colposcopic examination of the cervix of cebus monkeys.a total of 410 colposcopic examinations were performed on 188 female cebus monkeys that were under study to determine the oncogenic potential of herpes simplex virus type 2 in this genus. a split-cone vaginal speculum was developed that permitted good observation of the vaginal cervix in the cebus monkey. the cervical anatomy of cebus monkeys was found to differ from that of humans in that the surface of the animal cervix was more papilliform, with thinner squamous epithelium, and the squamocolu ...1978214730
recombinants between herpes simplex virus types 1 and 2: analyses of genome structures and expression of immediate early polypeptides.recombinants between temperature-sensitive mutants of herpes simplex virus types 1 (hsv-1) and 2 (hsv-2) were constructed. using restriction endonucleases, we analyzed the genome composition of 17 intertypic recombinants and detected crossovers in every region of the genome. the virion dna of one recombinant appeared to be largely "frozen" in two of the four possible genome arrangements of hsv. knowledge of the genome structures of recombinants enabled us to physically map immediate early polype ...1978214575
antibodies to herpes simplex virus types 1 and 2 in patients with squamous-cell carcinoma of uterine cervix in india.antibody activity to herpes simplex virus type-1 (hsv-1) and type-2 (hsv-2) was measured by the indirect hemagglutination (iha) test in sera from 124 women with squamous-cell carcinoma of the uterine cervix, 46 women with non-cervical cancer and 116 matched normal women. the type-specific antibodies were assayed by iha inhibition test. the proportion of cervical cancer cases positive for hsv-2 infection was significantly greater than that of non-cervical cancer cases and matched control women. n ...1978214407
a rational approach to the development of antiviral chemotherapy: alternative substrates of herpes simplex virus type 1 (hsv-1) and type 2 (hsv-2) thymidine kinase (tk). 1977212988
collaborative complementation study of temperature-sensitive mutants of herpes simplex virus types 1 and 2.twenty-three complementation groups of herpes simplex virus type 1 (hsv-1) and 20 of hsv-2 were identified by qualitative and quantitative complementation analysis from among 43 temperature-sensitive (ts) mutants of hsv-1 and 29 ts mutants of hsv-2 which had been isolated independently in 10 laboratories.1978212578
suppression of the synthesis of cellular macromolecules by herpes simplex virus.synthesis of cellular protein was substantially inhibited within 1 h of infection with herpes simplex virus, type 2, strain g (hsv-2). the inhibition also occurred, although no virus-specific protein synthesis was detected, after infection with u.v. irradiated virus and in cytoplasts that had been enucleated before infection. the inhibitory activity could not be distinguished from infectivity by dilution, sedimentation or reaction with gamma-globulin. hsv-2 also suppresssed the synthesis of send ...1978212520
optical diffraction analysis of electron microscope images of tubular structures found in cells infected with herpes simplex virus type 2.optical diffraction analysis was done on the electron micrographs of tubular structures found in cells infected with herpes simplex virus type 2. by this method, the helical arrangement of subunits forming a tubular structure was demonstrated.1978212515
molecular genetics of herpes simplex virus: demonstration of regions of obligatory and nonobligatory identity within diploid regions of the genome by sequence replacement and insertion.the dnas of herpes simplex virus (hsv) 1 and 2 consist of two components, l and s, each composed of unique sequences bracketed by inverted repeats. in this study we have probed the structure of the reiterated regions of the s component in marker rescue experiments involving transfection of cells with mixtures of intact hsv-1 mutant viral dna and individual dna fragments generated by restriction endonuclease digestion of wild-type hsv-1 or hsv-2 dnas. the results were as follows: (i) hsv is diplo ...1978211508
cellular immune response in genital herpes simplex virus infection.we studied the relations between the cellular immune response, pre-existing complement-fixing antibody and virus type with duration of virus excretion in genital herpes simplex virus (hsv) infection. thirty-six patients (seven with hsv-1 and 29 with hsv-2) with genital herpes underwent serologic testing, sequential viral cultures and weekly determination of lymphocyte-transformation stimulation index with inactivated hsv antic n. the duration of virus excretion was shortest in those with pre-exi ...1978211414
evidence for a herpes simplex virus-specific factor controlling the transcription of deoxypyrimidine kinase.a cistron-specific, enzyme-forming-capacity method was used to study the control of herpes simplex virus (hsv)-specific deoxypyrimidine kinase (dpyk) mrna synthesis. a virus-specific factor was formed by a primary infecting virus, and this factor effected the transcription of dpyk mrna of a superinfecting virus in the presence of cycloheximide, suggesting that the factor acted in "trans" and was a diffusible one. after the addition of actinomycin d to prevent further transcription and upon remov ...1978211259
herpes simplex virus types 1 and 2 in organotypic cultures of mouse central and peripheral nervous system. i. light microscopic observations of myelin degeneration.mature mouse spinal cord-ganglion cultures, which contain both peripheral and central nervous system as one unit, were infected with herpes simplex virus type 1 (hsv 1) or type 2 (hsv 2) and observed by bright field microscopy for up to 72 hours. there was degeneration of both central and peripheral myelin in cultures infected with either virus, but the pattern of peripheral myelin degeneration associated with hsv 1-infected cultures was differrnt from that in hsv 2-infected cultures. type 1 was ...1978211204
herpes simplex virus necleic acid synthesis following infection of non-permissive xc cells.dna hybridization kinetic analysis of cellular dna following high multiplicity infection of non-permissive xc cells by herpes simplex virus type i showed that hsv dna penetrates to the nucleus of the cell but that the number of virus dna copies present in each cell quickly begins to decline. there did not appear to be any net virus dna synthesis and the loss of virus dna copies continued until there was approximately one per haploid genome equivalent. hsv-2 likewise did not show any detectable v ...1978211197
complement-mediated cytolysis of hsv-1 and hsv-2 infected cells: plasma membrane antigens reactive with type-specific and cross-reactive antibody.surface antigens of bhk-21 cells infected with hsv-1 or hsv-2 were radioiodinated (125i) with lactoperoxidase, immune precipitated and analysed by polyacrylamide gel electrophoresis (page). experiments using antiserum to hsv-1 or hsv-2, absorbed with appropriate hemotypic or heterotypic antigens, revealed that both type-specific (homotypic) and cross-reactive antibody combined with surface glycoproteins to form a single large radioactive peak. this peak, which constituted the major glycoprotein ...1978211189
the fine structure of cells infected with temperature-sensitive mutants of herpes simplex virus type 2.the fine structure of cells infected with the hg 52 strain of herpes simplex virus type 2 and 13 temperature-sensitive mutants derived from it was investigated. in cells infected with the wild-type virus, development of virions appeared to be similar to that described in previous reports. however there were two exceptions to this: (1) capsid envelopment apparently occurred de novo in the nucleus; (2) densely staining vacuolar accumulations were seen, frequently surrounding virus capsids. the 13 ...1978211178
herpes simplex virus type 2 infection of neonatal mice.we have demonstrated that newborn mice can be infected orally with herpes simplex virus type 2. transplacental and transvaginal transmission of herpes simplex virus type 2 did not occur in our mice. failure to produce natural transvaginal infection in mice may be explained by the relatively short period of exposure to the virus during parturition. these experiments demonstrate that high oral doses of herpes simplex virus type 2 can produce disseminate herpes neonatal infection in mice and theref ...1978211091
effect of immunization on the development of latent ganglionic infection in mice challenged intravaginally with herpes simplex virus types 1 and 2.immunization of balb/c mice with virulent and avirulent strains of hsv-1 resulted in high levels of neutralizing antibody and protected against both the lethal effect of the virus and the development of a latent ganglionic infection when animals were challenged by the intravaginal route. in animals immunized with avirulent strain of hsv-2 and challenged with a high virulent strain of hsv-2, substantial protection against death was observed despite low levels of neutralizing antibody. nineteen pe ...1978210669
a nonlytic transforming mutant of herpes simplex virus type 2.a small-plaque mutant (no.69) of herpes simplex virus type 2 (hsv-2) strain 333 has been previously isolated and characterized in this laboratory. this mutant was shown to produce a high ratio of noninfectious to infectious particles when grown at the nonpermissive temperature in hamster embryo fibroblasts [westmoreland d. and rapp f. (1976). journal of virology [8:92--102]. in this study, we have demonstrated that it is possible to obtain noninfectious stocks of this virus which retain transfor ...1978210252
conditions required for induction of murine p30 by herpes simplex virus.mouse cells (line n cia cl10) contain 1.2-2.5 ng murine leukaemia virus (mulv) p30 antigen/mg of protein; this amount of antigen is measurable by competition radioimmunoassay (ria) but is not detectable by indirect immunofluorescence (if). infection of n cia cl10 cells with herpes simplex virus type 2 (hsv-2) induces expression of mulv p30. induction by hsv-2 does not require either cell or virus dna synthesis and is optimal 8 h post infection when cells at 50-70% confluence are infected at a mu ...1978210128

protective effect of an oral infection with herpes simplex virus type 1 against subsequent genital infection with herpes simplex virus type 2.the problem of whether oral herpes simplex virus type 1 (hsv-1) infection provides protection against subsequent genital infection by herpes simplex virus type 2 (hsv-2) was investigated. mice were used as models. following conditions in man, both the oral and genital infections applied were noninjurious. mice infected orally with hsv-1 were weakly protected against virus 'take' following vaginal challenge with hsv-2. genital 'takes' were found in 67% of the immunized mice, as compared with 83% ...1978209295
5,6-dihydro-5-azathymidine: in vitro antiviral properties against human herpesviruses.5,6-dihydro-5-azathymidine (dhadt), a novel water-soluble nucleoside antibiotic, inhibits herpes simplex virus type 1 (hsv-1) in appropriately infected cell cultures to a greater extent than herpes simplex virus type 2 (hsv-2). vaccinia virus was less susceptible than hsv-2, and pseudorabies virus yields were not reduced at the concentrations studied. plaque formation by varicella-zoster virus was suppressed by dhadt. dhadt was slightly toxic to cells at concentrations that were inhibitory for h ...1978208459
anatomy of herpes simplex virus (hsv) dna. x. mapping of viral genes by analysis of polypeptides and functions specified by hsv-1 x hsv-2 recombinants.in an earlier paper (morse et al., j. virol 24:231--248, 1977) we reported on the provenance of the dna sequences in 26 herpes simplex virus type 1 (hsv-1) x hsv-2 recombinants as determined from analyses of their dnas with at least five restriction endonucleases. this report deals with the polypeptides specified by the recombinants and by their hsv-1 and hsv-2 parents. we have identified (i) the corresponding hsv-1 and hsv-2 polypeptides with molecular weights ranging from 20,000 to more than 2 ...1978207894
alkaline dnase activity in cells infected with a temperature-sensitive mutant of herpes simplex virus type 2.bhk cells infected with the temperature-sensitive mutant ts13 of herpes simplex virus type 2 at a nonpermissive temperature lack the alkaline nuclease activity, which is induced by the mutant at a permissive temperature and by wild-type virus at either temperature. for ts13, enzyme activity could be induced by a temperature shift to permissive conditions, but not in the presence of cycloheximide. after a shift from permissive to nonpermissive conditions in the presence of cycloheximide, the acti ...1978207883

congenital herpes simplex virus, type 2, bilateral endophthalmitis.a set of dizygotic twins, both born prematurely, developed herpes simplex encephalitis shortly after birth. the second twin had unilateral keratoconjunctivitis and bilateral endophthalmitis and subsequently died from disseminated herpes infection. herpes simplex, type 2, was isolated from conjunctiva of both eyes, cerebrospinal fluid, nasopharynx and trachea. histologic examination of the eyes reveaed bilateral endophthalmitis with a necrotizing retinitis. intranuclear inclusion bodies were demo ...1977206999
biochemical transformation of mouse cells by herpes simplex virus type 2: enhancement by means of low-level photodynamic treatment.the biochemical transformation of thymidine kinase-deficient cells by uv-inactivated herpes simplex virus is enhanced by low-level photodynamic treatment of the infected cells. at the concentration of proflavine used, the virus was not inactivated and both virus and cellular dna syntheses were only marginally inhibited. the observed enhancement of the transfer of a virus gene to the cell genome suggests a possible cocarcinogenic role for photodynamically active dyes at very low concentrations.1978206727
the deoxyribonuclease induced after infection of kb cells by herpes simplex virus type 1 or type 2. i. purification and characterization of the enzyme.the deoxyribonuclease induced in kb cells by herpes simplex virus (hsv) type 1 and type 2 has been purified. both enzymes are able to completely degrade single- and double-stranded dna yielding 5'-monophosphonucleotides as the sole products. a divalent cation, either mg2+ or mn2+, is an absolute requirement for catalysis and a reducing agent is necessary for enzyme stability. the maximum rate of reaction is achieved with 5 mm mgcl2 for both hsv-1 and hsv-2 dnase. the optimum concentration for mn ...1978206546
role of activated macrophages in resistance of congenitally athymic nude mice to hepatitis induced by herpes simplex virus type 2.congenitally athymic nude (nu/nu) mice of a balb/c genetic background were found considerably more resistant to the induction of focal necrotic hepatitis by herpes simplex virus type 2 (hsv-2) tha, were phenotypically normal littermates (nu/+) or balb/c mice. the augmented resistance was age dependent, as it was only manifested in mice from 4 to 5 weeks of age. studies of the course of infection showed that nude mice were able to restrain virus multiplication in the liver far better than normal ...1978205507
production of plasminogen activator by cells transformed by herpesviruses.plasminogen activator is produced by hamster cells transformed by human herpesviruses. these cell lines have previously been shown to be oncogenic when injected s.c. into newborn syngeneic hamsters. lysis of fibrin overlays by these cell lines was plasminogen dependent. normal hamster embryo fibroblasts and a hamster cell line transformed by para-7 (an adenovirus-sv 40 hybrid) failed to produced lysis. in separate experiments fibrin overlay of lytically infected secondary rabbit kidney cells did ...1978205345
induction capacity and influence of dthdmp on thymidine kinase activity of type 1 and 2 strains of herpes simplex virus.the thymidine kinase inducing ability of 104 strains of herpes simplex virus was studied comparatively. a pronounced relationship was established between induction of the enzyme and the serotype of the strains. as a rule, the strains of serotype 2 are weaker inducer of dthd- and dcyd-kinase activity than serotype 1 strains. a certain parallelism exists between induction of both enzymes, however the activity of the thymidine kinase increases after infection with herpes simplex virus 4--5 times mo ...1978205197
chromosome abberations in rat embryo cells transformed after infection with ultraviolet-irradiated herpes simplex virus.two rat embryo cell lines (tr1 and tr2) transformed after infection with ultaviolet-inactivated herpes simplex virus type 2 showed modal chromosome numbers in the tetraploid range. in the tr1 cell line a near-diploid cell population replaced during subcultivation the hypotetraploid cells thus explaining the loss of immunofluorescent viral antigens. both transformed cell lines showed frequent achromatic gaps. in the tr1 cell line such gaps were preferentially located in specific chromosome region ...1978205041
incidence and distribution of herpes simplex virus types 1 and 2 from genital lesions in college women.during a 9-month period, 9,772 women were treated at the student health center's gynecology clinic. herpes simplex virus was isolated from 30 of 57 patients clinically diagnosed as suffering from a herpetic or herpetic-like genial infection for a virological incidence rate of 0.31%. using virus plaque diameter in chick embryo cells and heat stability of viral thymidine kinase, 37% of the isolates were classified as herpes simplex virus type 1 and 63% were classified as herpes simplex virus type ...1977204741

induction of latent herpes simplex virus type 2 infection in human cervical epithelial cells in vitro.an in vitro method was used to induce non-productive herpes simplex virus type 2 (hsv-2) infections in human ecto- and endocervical epithelial cells. adenine arabinoside (ara-a) could prevent the replication of hsv-2 in ecto- and endocervical cells and after removal of ara-a from growth medium a rapid destruction of explants with development of infectious virus was observed. when ara-a was not withdrawn until 4 days or later after in vitro infection the morphological, immunofluorescent and virol ...1977203162
an investigation into the relationship of the immunological status of herpes simplex virus type-2 (hsv-2) infected animals and the tumor-enhancing property of this infection.in order to compare the state of immunity of hsv-2 infected animals with their sham treated counterparts, several in vivo methods for cell-mediated immunity in addition to the stimulation in vitro of mouse splenocytes with pha were performed. the grafting of c 3 h mice with heterologous skin and the paw test with pha showed no noticeable difference between the two groups. the tuberculin test performed on guinea pigs infected via the footpads, permitted the detection of a slightly impaired reacti ...1977201898
studies on tumors produced by cells transformed with herpes simplex virus type 2.biological, histological, and ultrastructural studies were made on tumors produced in weanling hamsters inoculated with hamster embryo fibroblasts (hef) transformed by herpes simplex virus type 2 or with cultured cells (tumor cell lines t1 and t2) derived from the tumor tissues. the malignancy of transformants increased through passages in vitro and in vivo. histologically, two tumor cells lines (155-4t1 and u-15t1) produced fibrosarcomas and one (u-26t1) produced lesions resembling "malignant f ...1977201537
[herpes simplex virus (hsv-1 and hsv-2) infection: its clinical and oncogenic properties (author's transl)].the epidemiology and clinical features of diseases caused by the herpes simplex virus, are reviewed and recent results are discussed which give an insight into the complex mechanism of primary and chronic, recurrent hsv-1 infections. immunological reactions in hsv infection and data concerning the oncogenic potential of hsv-1 and -2 are dealt with. furthermore, current therapeutic possibilities are outlined.1977201107
unexpected disseminated herpes simplex infection in a newborn.disseminated herpes simplex virus type 2 was unexpectedly discovered in a baby delivered by primary cesarean section at 36 weeks' gestation prior to rupture of the membranes. the mother was free of orogenital lesions at each prenatal examination. examination of the placenta revealed chorioamnionitis implicating an ascending infection from the mother's infected genital tract.1977200876
complement-dependent cytotoxic antibodies in the course of cervical carcinoma.complement-dependent cytotoxic antibodies to three cervical carcinoma cell lines (me-180, sw-732 and hela) and to herpes simplex virus type 2 (hsv-2)-infected cells were determined in a long-term study of women with cervical carcinoma. cytolysis of surface antigens differed significantly between the cervical carcinoma cell lines and hsv-2. regression of the tumor during treatment was accompanied by decreasing cytolysis in the cervical carcinoma lines, while tumor bearers and patients who became ...1977200570
specifically immune mouse t-cells can destroy h-2 compatible murine target cells infected with herpes simplex virus types 1 or 2.lymphocytes from the spleen (sl) or peritoneal cavities (pl) of hsv-1- or hsv-2-immunized c 3 h mice expressed pronounced cytotoxicity, as measured by 51cr release assay, against l cells experimentally infected with hsf-types 1 or 2 but not against uninfected l cells. hsv-1 or hsv-2 immune lymphocytes induced substantially more 51cr release when l-cell targets were infected with homotypic virus compared to those infected with heterotypic virus. inasmuch as the cytotoxicity of specifically immune ...1977198986
prolongation of herpes simplex virus latency in cultured human cells by temperature elevation.treatment of herpes simplex virus type 2 (hsv-2)-infected human fibroblast cells with cytosine arabinoside (ara-c) at 25 microgram/ml resulted in complete inhibition of virus replication. removal of ara-c after 7 days of treatment ultimately resulted in renewed virus replication, but after a delay of at least 5 days. if however, the temperature was elevated from 37 degrees c to 39.5 to 40 degrees c at the time of ara-c reversal, infectious hsv-2 did not reappear. as long as the cultures were mai ...1977198583
anatomy of herpes simplex virus dna. ix. apparent exclusion of some parental dna arrangements in the generation of intertypic (hsv-1 x hsv-2) recombinants.we are reporting the physical location of parental dna sequences in 28 recombinants produced by crossing herpes simplex viruses (hsv) 1 and 2. the parental crosses were of two kinds. in the first, temperature-sensitive mutants of hsv-1 and hsv-2 were crossed to produce wild-type recombinants. in the second, temperature-sensitive mutants of hsv-1 rendered resistant to phosphonoacetic acid were crossed with wild-type hsv-2, and recombinants that multiplied at nonpermissive temperature and were res ...1977198577
antiviral activity of arabinosylthymine in herpesviral replication: mechanism of action in vivo and in vitro.1-beta-d-arabinofuranosylthymine (ara-t), a metabolite of the sponge tethya crypta, has shown selective activity against herpes simplex virus (hsv) replication (g. a. gentry and j. f. aswell, virology 65:294-296, 1975). analysis of hsv-infected and uninfected cell lysates by cscl isopycnic centrifugation showed that ara-t blocked the incorporation of [(3)h]hypoxanthine into viral deoxyribonucleic acid and, to a large extent, into host deoxyribonucleic acid of infected (but not uninfected) cells. ...1977197886
the photoinactivation of an rna animal virus, vesicular stomatitis virus, with the aid of newly synthesized psoralen derivatives.the newly synthesized psoralen derivatives, 4' hydroxymethyl 4,5',8 trimethylpsoralen, 4' methoxymethyl 4,5',8 trimethylpsoralen, and 4' aminomethyl 4,5',8 trimethylpsoralen hydrochloride photoreact with the single-stranded rna animal virus, vesicular stomatitis virus, vsv. this virus is inactivated 10(3) times more effectively by photoreaction with these compounds than when photoreacted with 4,5',8 trimethylpsoralen. under these conditions the rna virus remains more than 10(3) times less sensit ...1977197489
laser cytophotometric detection of variations in spatial distribution of concanavalin-a cell surface receptors following viral infection.human cells in culture (h.ep. 2) were infected with herpes simplex virus type 2 at a multiplicity of infection (m.o.i.) of 3 for 3, 18 and 36 hr. spatial redistribution of concanavalin (con-a) cell surface receptor sites was detected by an indirect double-antibody (peroxidase-conjugated goat anti-rabbit to rabbit anti-con-a) immunoenzymatic staining reaction which rendered the con-a sites visible to light microscopy and to flow laser cytophotometry. significant spatial redistribution of cell sur ...1977197163

effect of silica on the pathogenic distinction between herpes simplex virus type 1 and 2 hepatitis in mice.the role of macrophages in the difference in liver pathogenicity between herpes simplex virus type 1 (hsv-1) and type 2 (hsv-2) in mice was investigated by selectively blocking the macrophage function of the mice by silica. intravenous administration of 3 mg of silica 2 h before virus inoculation partially abolished the difference between the two virus types, as judged by macroscopic and microscopic examination of the livers and by virus isolation studies. intraperitoneal inoculation of 50 mg of ...1977197016
genetics of macrophage-controlled resistance to hepatitis induced by herpes simplex virus type 2 in mice.the genetics of innate resistance of mice to hepatitis induced by herpes simplex virus type 2 (hsv-2) was analyzed by crossing resistant male gr to susceptible female balb/c mice and backcrossing females of this f1 generation to susceptible male balb/c mice. by scoring of macroscopic liver lesions and virus isolation studies from the liver 4 days after intraperitoneal inoculation of hsv-2, it appeared that the resistance was governed by one x-linked dominant gene or closely linked gene complex, ...1977197015
type specificity and use of human sera for rapid typing of herpes simplex virus isolates by an indirect peroxidase-labeled antibody technique: a comparison with three other methods.human sera from patients showing seroconversion following a primary herpes simplex virus type 1 (hsv-1) or hsv type 2 (hsv-2) infection, as well as 19s and 7s fractions obtained from the same sera, have been used for typing 191 hsv isolates by an indirect peroxidase-labeled antibody (pla) method. typing has also been performed on all of the isolates using a microneutralization (mn) and the indirect hemagglutination (iha) inhibition test. furthermore, 30 isolates have been typed by a plaque metho ...1977196572
ultrastructural effects of herpes simplex virus type 2 infection of rat dorsal root ganglia in culture.the ultrastructural consequences of herpes simplex virus type 2 (strain r-2) infection of organotypic cultures of embryonic rat dorsal root ganglia were studied. the intial consequences (dilation of endoplasmic reticulum and/or golgi apparatus and distortion of mitochondrial structure) occurred in the cytoplasm. these effects were followed by several nuclear changes including loss of nucleoplasm, and margination of chromatin. extensive nuclear membrane proliferation was accompanied by the viral ...1977196052
quantification of the herpes simplex virus dna present in biochemically transformed mouse cells and their revertants.four cell lines biochemically transformed by u.v.-irradiated herpes simplex virus contain virus dna fragments ranging from 3 to 22% of the hsv genome. of five revertant clones selected for 3h-tdr or brdurd resistance, four had lost all detectable virus dna while the fifth, selected for brdurd resistance, retained the entire virus fragment but there was a reduction of virus copies per cell from 5 to 1. three 'supertransformed' revertant cell lines contained virus dna fragments ranging from 12 to ...1977196037
purification of herpesvirus nucleocapsids by fluorocarbon extraction.purified nucleocapsids were prepared from herpes simplex virus type-1 and herpes simplex virus type-2 infected cells, using a fluorocarbon extraction technique with freon 113. fifty to 85% of the total nucleocapsid population remained 'nucleated' or full in terms of the nucleic acid core making them useful as a source of dna. cscl banded dna represented 30--40% of the theoretical yield of the total nucleocapsid population.1976195183
biochemical transformation of mouse cells by fragments of herpes simplex virus dna.mouse l cells lacking the enzyme thymidine kinase (lmtk-) have been converted to a tk+ phenotype by infection with fragmented hsv2 strain 333 dna. the dna fragments used were either unique, produced by cleavage with the restriction endonucleases eco ri and hild iii, or randomly produced by mechanical shearing. survival in hat medium was used initially to establish the tk+ phenotype; clones possessing the ability to grow in selective medium were picked on the basis of differing morphology and gro ...1977194705

multicystic cerebral degeneration in neonatal herpes simplex virus encephalitis.typical herpetic papulovesicular skin lesions developed in an apparently normal infant at 12 days of age and were followed within 48 hours by signs and symptoms of acute encephalitis. herpes simplex virus type 2 was cultured from the intact skin vesicles, and a fourfold increase in complement fixation titer to herpes simplex virus type 2 was found over the ensuing 24 days. the infant survived her acute illness, but was left with severe neurologic sequelae manifested as microcephaly with multicys ...1977193394
[epidemiology of herpes simplex diseases].the epidemiological principle of the herpes simplex virus (hsv) infections is to have the affected host survive, to persist in it and thus to make it to be a life long starting point for new infection chains. there is an accurately tuned correlation between virus and host organism, in which the persistence of the virus as a latent infection in the ganglion cells of sensory neurones is of central importance. in this state the virus cannot be attacked by the defensive power of the body. when chang ...1977193312
[oncogeny of herpes simplex viruses and lupidon].the part of the herpes simplex virus type 2 in the development of the cervex carcinoma of women is still an open question. after the serological findings that patients with cervix carcinoma have a higher rate of antibodies against type 2 than healthy women, which were initially published with great expectation, the molecular-virological examinations which were meanwhile carried out by several work groups to find traces of the herpes simplex virus type 2 in the carcinoma cells were negative, exce ...1977193311
transfer of the gene for thymidine kinase to thymidine kinase-deficient human cells by purified herpes simplex viral dna.transformation of human cells from a thymidine kinase (atp:thymidine 5'-phosphotransferase, ec 2.7.1.75)-negative to a thymidine kinase-positive phenotype has been achieved by using purified dna from herpes simplex virus type 2. the specific activity of the dna was in the range 0.5 to 2.0 transformants per microng and the efficiency of gene transfer was up to 1 transformant per 10(5) recipient cells. several transformed lines able to grow continuously in medium selective for thymidine kinase-pos ...1977193108
the tumor enhancing property of herpes simplex virus type-2 (hsv-2).the s.c. infection of dbf-1 mice with hsv-2 has a tumor enhancing effect on simultaneously i.m. implanted mca-induced syngeneic spindle cell sarcoma. thus with the dosage used here, the first palpable tumors appeared on day 6 in the virus treated group as compared to day 9 p.i. in the sham treated batch. further, more tumors were formed: 75% among the infected and 40% among the sham injected. the tumor yield could be modulated: no difference between the 2 groups was found when the tumor cell dos ...1977193079

comparative effects of herpes simplex virus types 1 and 2 in organotypic cultures of mouse dorsal root ganglion.mature organized cultures of mouse dorsal root ganglion (mdrg) were infected with herpes simplex virus, type 1 (hsv 1) and type 2 (hsv 2). onset of infectious virus production occurred faster and reached higher levels in hsv 2-infected cultures. neurons, supporting cells and myelin were affected in both types of infection, but morphological changes occurred significantly earlier and more dramatically with the type 2 infection. the pattern of myelin changes was distinctly different in the two typ ...1977192854
effect of immunization on acute and latent infections of vaginouterine tissue with herpes simplex virus types 1 and 2.inoculation of mice with herpes simplex virus types 1 and 2 (hsv-1 and hsv-2) by the vaginal route resulted in viral shedding during the acute phase of the infection and the development of a latent infection in vaginouterine tissue lasting up to one year in greater than 25% of the animals. immunization with either serotype of hsv markedly reduced viral shedding when animals were subsequently challenged with the homologous serotype, but immunization with hsv-2 was significantly less effective in ...1977192810
a sensitive method for the detection of herpes simplex virus type 2 specific thymidine kinase.thymidine kinase (tk) activity of uninfected and in vitro herpes simplex virus type 2 (hsv-2) infected human fetal lung cells was analyzed. polyacrylamide gel electrophoresis was carried out, and subsequent incubation of equally divided gel slices in the presence of normal or anti-hsv-2 specific tk serum, together with different substrates, was performed. small amounts of virus-specific enzyme could be detected using this combination of electrophoresis and antibodies and replacing atp by ctp in ...1977192698
role of macrophages in hepatitis induced by herpes simplex virus types 1 and 2 in mice.a marked difference was found between herpes simplex virus type 1 (hsv-1) and type 2 (hsv-2) in the induction of hepatic necrotic lesions in mice inoculated intraperitoneally. although hsv-2 produced many large, progressive liver lesions in 4-week-old balb/c mice, hsv-1 only occasionally induced a few, self-limiting foci, which eventually healed. this was reflected in the isolation of hsv from the liver and spleen, two organs that are rich in macrophages. although hsv-1 could be only temporarily ...1977192671
[prevention and therapy of viral diseases with special reference to interferon].human leukocyte interferon (hli) was used for treatment of human diploid fibroblasts before and after infection with vaccinia virus, herpes simplex virus type 1 (hsv 1), herpes simplex virus type 2 (hsv 2), and varicella zoster virus (vzv). vero cells were infected with medical lake macaque herpes virus (mlmv), and treated with hli in the same way. in all of these systems hli exhibited an antiviral effect when administered before infection, and this effect could be increased by additional hli tr ...1977192653
specific non-immunoglobulin g antibodies and cell-mediated response to herpes simplex virus antigens in women with cervical carcinoma.non-immunoglobulin g-neutralizing antibodies to herpes simplex virus (hsv) type 2 were assayed in sera adsorbed with staphylococcus aureus cowan i. they were present in 8% of women with normal cervical smear and in 20, 41, and 74% of women with atypia, dysplasia, and cervical carcinoma, respectively. lymphocytes of the patients were tested for in vitro transformation by killed hsv type 1 and hsv type 2 (hsv-2), as well as by mitomycin c-treated hamster cells transformed by hsv or other viruses o ...1977192446
immunodiagnostic potential of a virus-coded, tumor-associated antigen (ag-4) in cervical cancer.the central theme of this communication is the recognition of an immunodiagnostic potential in a herpes virus antigen, the molecular interrelationship of which with cervical tumor cells is described. in addition to the productive infection caused by herpes simplex virus type 2 (hsv-2) we are confronted by latency and, as suggested by recent studies, by cancer. these different types of virus-host cell interactions are discussed at the host, as well as at the cellular level. a defined level of mol ...1977192436
long-term follow-up studies on herpes simplex antibodies in the course of cervical cancer: patterns of neutralizing antibodies.the kinetics of neutralization was used to study antibodies to herpes simplex virus type 2 in 90 patients with invasive carcinoma of the cervix uteri. the first sera were drawn before treatment and consective sera were drawn at intervals thereafter. control groups consisted of 90 age-matched healthy women and 70 cancer patients suffering from malignancies other than cervix carcinoma. patients surviving during the observation period of 12-60 months had a significantly higher frequency of neutrali ...1977192072
[investigations concerning the evidence of herpes simplex virus type 2 (hsv-2) antibodies in patients with carcinoma of the cervix (author's transl)].the neutralizing antibodies to hsv-1 and hsv-2 were determined in the sera of 128 patients. infection was detectable in nearly 100% of the cases in each of the three investigated groups (patients with carcinoma of the cervix, female patients with chronic recurrent hsv infection in the genital area and a control group without and history of hsv infection). the percentage of patients displaying hsv-2 antibodies in the group with carcinoma of the cervix (38%) is significantly higher than in the con ...1977191994
herpes simplex virus type 2 meningitis.to date only 9 culture-proven cases of herpes simplex virus type 2 meningitis have been recorded. presented here is the 10th case with a review of the literature. although generally a benign disease, its recognition in association with herpes progenitalis must be appreciated to avoid confusion in the treatment of this common veneral disease.1977191771
herpes simplex virus types 1 and 2 in clinical infections: differences observed by electron microscopy.microtubule-like structures have been observed ultrastructurally in bhk-21/4 cells infected with herpes simplex virus type 2 (hsv-2) but not in cells infected with herpes simplex virus type 1 (hsv-1). bhk-21/4 cells were infected with two known strains of hsv-2 and one known strain of hsv-1, as well as with vesicular fluid from 50 clinical isolates (47 perioral, two penile, and one from the leg) in an examination of the accuracy of electron microscopy for differentiation between clinical isolate ...1977191545
cell-mediated immune responses in recurrent herpesvirus infections. i. lymphocyte proliferation assay.studies in immunosuppressed and immunodeficient patients indicate that the cell-mediated immune response appears to be responsible for controlling reactivated herpesvirus infections. in this study, the various parameters of a herpesvirus (types 1 and 2) antigen specific lymphocyte proliferation assay were optimized and used to evaluate individuals with clinical, recurrent hsv-1 and hsv-2 infections. normal individuals with neutralizing antibody to hsv-1 or hsv-2 responded to virus antigen in cul ...1977191528
preliminary studies of nonvirion antigens associated with herpes simplex virus 1 and 2 (hsv1 - hsv2).biochemical and radioimmunological studies have indicated the presence of a nonvirion antigen associated with herpes virus. guinea pig kidney cells were grown in culture and infected (i-cells) for 3h with herpes virus. uninfected cells (n-cells) served as control. the cells were collected and sonicated to obtain, after centrifugation, "soluble extract" (si, sn). the pellets were extracted with kcl (isp, nsp). sn, si were submitted to gel-filtration on sephadex g-200. extracts from i and n cells ...1976191042

correlation of herpes simplex virus types 1 and 2 with clinical features of infection.strains (338) of herpes simplex virus (hsv) were isolated in stockholm during 1965-1974. by immunoelectroosmophoresis it was possible to identify all strains as either hsv type 1 (hsv-1) or 2 (hsv-2). no strains of intermediate antigenic type or with untypable characteristics were found. the antigenic type of hsv was correlated with body site and clinical features of infection. a case of severe, recurrent, abdominal pain in association with hsv-2 infection is described. in one patient with acute ...1977188954
dna-binding proteins of cells infected by herpes simplex virus type 1 and type 2.proteins showing affinity for dna in hsv-1-and hsv-2-infected cells were compared by dna-cellulose chromatography and page. the proteins observed depended on the type of virus used to infect the cell; however, several examples of analogous polypeptides were present in cells infected by both virus types. proteins showing highest affinity for dna-cellulose were similar in molecular size in cells infected by both virus types.1976188782
cell surface antigens induced by herpes simplex virus (hsv).among the antigens induced by hsv on the surface of infected cells there are antigens binding anti-hsv antibodies by their combining (fab) site (hsv-ag), and others binding antibodies of various specificities, probably through their fc fragment (igr). hsv-ag were demonstrated by cytotoxicity and mixed agglutination tests; igr were made evident by passive hemadsorption. the ability to induce igr is especially characteristic of hsv-1 strains, being absent or limited with hsv-2 strains. igr were no ...1976188230
immune interactions with cells infected with herpes simplex virus: antibodies to radioiodinated surface antigens.lactoperoxidase-catalyzed radioiodination was used to study reactions between surface antigens and antibodies on bhk-21 cells infected with hsv-1 and hsv-2. isolation of iodinated surface antigens was achieved by indirect immune precipitation of triton x-100 disrupted cells with antisera to hsv and igg. analysis of immune precipitates by polyacrylamide gel electrophoresis (page) revealed at least 10 antigens, ranging in m.w. from 35 x 103 to 160 x 103 daltons. antigens were detectable on cell su ...1977187696
lasar flow cytophotometric immunoperoxidase detection of herpes simplex virus type 2 antigens in infected cultured human cells.human cells in culture (hep-2) were infected with herpes simplex virus type 2 (hsv-2) at multiplicities of infection varying from 0.2 to 10, and fixed 6, 12, 18 and 24 hr after infection. infection-related antigens were detected by an indirect double antibody (peroxidase conjugated goat anti-rabbit to rabbit anti-herpes simplex virus type 2) immunoenzymatic staining reaction that rendered infection-related antigens visible by light microscopy. a corresponding series of laser flow cytophotometric ...1976187690
comparison of dna polymerase activities induced by herpes simplex virus types 1 and 2.hsv-2-induced a salt-stimulated dna polymerase activity in hep-2 cells at similar levels to that induced by hsv-1 virus at multiplicites of infection from 2 to 20 pfu/cell. de novo synthesis of protein and mrna was required for dna polymerase induction by both types. dna polymerase activity of three strains of each type was compared by response to various salt concentrations and by heat inactivation. strain-dependent, but not type-dependent differences were found by both tests. considerable cros ...1975187552
reaction of antigens isolated from herpes simplex virus-transformed cells with sera of squamous cell carcinoma patients.antigens isolated from herpes simplex virus type 1, herpes simplex virus type 2, or cytomegalovirus-transformed hamster cells were tested against 66 sera from non-cancer individuals or patients with different types of cancer. by use of the microcomplement fixation procedure to quantify all antigen-antibody interactions, it was observed that 94% (p less than 0.001) of all sera from patients with squamous cell carcinoma reacted with antigens from herpes simplex virus type 1-transformed cells, whil ...1976187320
herpesviruses and cancer in man and subhuman primates.because there is strong evidence for the involvement of epstein-barr virus in the etiology of burkitt's lymphoma and nasopharyngeal carcinoma, we have discussed the relationship of epstein-barr virus to these two diseases in the context of geographic distribution, pathology, epidemiology, genetics, immunovirology, and biochemistry. we have also discussed the relationship of epstein-barr virus to other diseases, both malignant and non-malignant. although the etiologic relationship of herpes simpl ...1976187259
comparison of dna facilitators in the uptake and intracellular fate of infectious herpes simplex virus type 2 dna.the comparative efficiencies of polyornithine, cacl2 and deae-dextran in enhancing the infectivity of exogenous herpes simplex virus (hsv) type 2 dna were examined. cacl2 was 12-times more effective in promoting genetic expression of viral dna than deae-dextran, while polyornithine did not mediate any hsv dna infectivity. a comparison of sedimentation profiles of dna extracted from cells inoculated with viral dna in the presence of each facilitator revealed that input 56 s hsv dna underwent mark ...1976187236
studies on kinetics of dna synthesis in cv-1 cell cultures infected with different multiplicities (moi) of herpes simplex virus type 2 (hsv-2).infection of cv-1 cell cultures with hsv-2 at moi 5 respectively 1pfu/cell resulted in markedly different patterns of dna-synthesis. isolation and separation of cellular and viral dna on cscl equilibrium density gradients during the "late" phase after infection with 5pfu/cell revealed a rapid increase in synthesis of virus-specific dna (which banded at density q25 = 1.729 g/ccm) while synthesis of host cell dna (banding at 1.705 g/ccm) was constantly inhibited. 15 hours after infection and incub ...1976186742
replication of herpes simplex virus in mouse spleen cell cultures stimulated by lipopolysaccharide.replication of hsv was demonstrated in spleen cell cultures of d2 and several other strains of mice after prestimulation with mitogenic doses of lps for 2 days. no viral replication occurred in unstimulated cultures or in cultures prestimulated with pha and con a, whereas there was some viral replication in spleen cell cultures of d2 mice after prestimulation with poly i-c. spleen cells of b6 mice did not support replication of hsv under any of the conditions we have tested thus far. the reasons ...1976186534
plaque dissociation of herpes simplex viruses: biochemical and biological characters of the viral variants.polycaryocytogenic (p) and non-polycaryocytogenic, or aggregating (a), stable variants were selected from a herpes simplex virus type 1 (hsv-1) and from a herpes simplex virus type 2 (hsv 2) which had not been deliberately exposed to known mutagenic agents. the p variant of hsv-1 (fp) differed from the a variant (fa) in polypeptides and glycoprotein patterns, but no gross differences were evident between the two variants of hsv-2 (gp and ga). each p variant proved more 'specific' than each a var ...1975186433
