| relationship of herpes simplex virus type-2 antibodies and squamous dysplasia to cervical carcinoma in situ. | serum specimens from 75 women with cervical carcinoma in situ, 84 with squamous dysplasia, and 132 controls, who had previously been interviewed and tested for complement fixing antibodies against a number of organisms, were analyzed for hsv-2 antibodies. carcinoma in situ and severe dysplasia were associated with hsv-2 antibodies. mild dysplasia was related to evidence of prior infection by trichomonas vaginalis, adenoviruses, and mycoplasma pneumoniae, plus a history of vaginal discharge. seve ... | 1978 | 215294 |
| comparison of various macrophage-inhibitory agents on vaginal and systemic herpes simplex virus type 2 infections. | pretreatment of mice intraperitoneally with silica, trypan blue, or dextran sulfate to inhibit macrophage function markedly increased the lethality of a systemic intravenous infection with herpes simplex virus type 2, but did not affect the lethality or local virus growth after vaginal infection of mice with herpes simplex virus type 2. agents which inhibit macrophage function by different mechanisms decreased host resistance to herpes simplex virus type 2, but the effects of macrophage-inhibito ... | 1978 | 215548 |
| characterization of human tk- cell lines transformed to a tk+ phenotype by herpes simplex virus type 2 dna. | human tk- cells carrying the hsv-2 tk gene as a result of transformation with virus dna express a tk activity of virus origin and maintain the tk+ phenotype when grown in hat medium. under non-selective conditions, however, reversion to a tk- phenotype occurs with a significant frequency characteristic of each transformed line. once reversion has occurred the tk- phenotype appears to be stable, since only very rare instances of tk- to tk+ reversion have been observed. tk- revertants were suscept ... | 1979 | 215706 |

| reversible inhibition of the induction of dna polymerase of herpes simplex virus type 2 in hela cells. | the induction of dna polymerase of herpes simplex virus type 2 in hela cells was inhibited by 2-mercapto-1-(beta-4-pyridethyl)benzimidazole added at an early time after infection. however, the inhibitory effect was easily released by removal of the inhibitor. since the drug disorganizes nucleolar structure and prevents its function in hela cells in a reversible manner, it is possible that nucleoli are involved in the induction of dna polymerase of this virus. | 1978 | 216336 |
| lymphocyte stimulation by herpes simplex virus (hsv) antigens. 1. culture conditions, cell fractionation and presentation of hsv antigens. | optimal culture conditions for rabbit lymphocytes were established. inclusion of 2-mercaptoethanol in the medium greatly enhanced responses. lymphocytes from the blood of hsv-immunized rabbits responded specifically in vitro to heat-killed (56 degree, 60 min) or uv-inactivated hsv preparations. a uv dose of 13,392 ergs/mm2 was the most suitable inactivating dose. oral intramucosal injection was the most effective way of generating blood lymphocyte responses to hsv, but animals immunized in trade ... | 1977 | 216529 |

| extreme sensitivity of enveloped viruses, including herpes simplex, to long-chain unsaturated monoglycerides and alcohols. | unsaturated monoglycerides and alcohols of chain lengths of 16 or 18 carbons were found to be extremely potent inactivators of two enveloped viruses, herpes simplex virus type 2 and bacteriophage phi6. the lipid-containing bacteriophage pm2 was also inactivated by some of these amphiphilic molecules. treatment of herpes simplex virus type 2 with these compounds at concentrations as low as 0.2 mum reduced virus survival to 50% in 30 min, making these agents the most potent inactivators of herpes ... | 1979 | 218499 |
| herpes simplex virus types 1 and 2 in organotypic cultures of mouse central and peripheral nervous system. 2. electron microscopic observations of myelin degeneration. | organotypic cultures of mouse spinal cord with attached dorsal root ganglia, which contain both central and peripheral myelin in the one unit of tissue, were infected with hsv 1 or hsv 2 and studied using electron microscopy. intranuclear viral nucleocapsids and intracytoplasmic enveloped particles were found in the schwann cells associated with peripheral myelin and in oligodendroglia associated with central myelin. degeneration of peripheral myelin most commonly involved an asymmetrical swelli ... | 1979 | 219153 |
| herpes simplex virus type 2 functions expressed during stimulation of human cell dna synthesis. | experiments were designed to identify herpes simplex virus type 2 (hsv-2)-specific functions expressed during stimulation of human embryo fibroblast dna synthesis. cultures were partially arrested in dna synthesis by pretreatment with 5-fluorouracil and maintenance in low-serum (0.2%) medium during virus infection. results showed that continuous [methyl-(3)h]thymidine uptake into cellular dna was ninefold greater in hsv-2-infected than in mock-infected cultures measured after 24 h of incubation ... | 1979 | 219236 |
| molecular genetics of herpes simplex virus. ii. mapping of the major viral glycoproteins and of the genetic loci specifying the social behavior of infected cells. | we have mapped the location in herpes simplex virus (hsv) dna of (i) three mutations at different loci (syn loci) which alter the social behavior of infected cells from clumping of rounded cells to polykaryocytosis, (ii) a mutation which determines the accumulation of one major glycoprotein [vp8.0(c(2))], and (iii) the sequences encoding four major virus glycoproteins [vp8.0(c(2)), vp7(b(2)), vp8.5(a), and vp19e(d(2))]. the experimental design and results were as follows. (i) analysis of hsv-1 x ... | 1979 | 219254 |
| anatomy of herpes simplex virus dna. xi. apparent clustering of functions effecting rapid inhibition of host dna and protein synthesis. | herpes simplex virus type 2 (hsv-2) strains inhibit the synthesis of both dna and protein of the host cell more rapidly than hsv-1 strains. several intertypic hsv-1 x hsv-2 recombinants and parental strains were examined for their ability to inhibit rapidly the synthesis of host protein and dna. the two functions cosegregated in all of eight recombinants tested and are therefore controlled by the same gene or by different genes in the same region of the viral dna. | 1979 | 219262 |
| reactivation of herpes simplex virus (type 2) infection in trigeminal ganglia and oral lips with cyclophosphamide treatment. | age-dependent resistance in trigeminal nerve against type 2 herpes simplex virus infection through oral lips and reactivation of the latent virus infection with cyclophosphamide in the ganglion in correlation to theprimary infected part were studied in mice with immunofluorescent and histopathological methods. the mice acquired resistance in the nervous tissue after 8 weeks of age. the viral antigen appeared in all trigeminal ganglia immediately after infection, but not found at 4 weeks later. r ... | 1978 | 219274 |
| [comparative study of the effectiveness of the purification and concentration of herpes simplex virus types 1 and 2]. | the results of comparative studies on concentration and purification of herpes simplex virus type 1 and type 2 (hsv-1 and hsv-2) by ficol density gradient centrifugation are presented. a two-phase distribution of extracellular hsv was established in phycol density gradient centrifugation: in zones with density of 1.110-1.114 and 1.088-1.085 g/ml. the effectiveness of purification of hsv preparations recovered from the corresponding gradient zones was determined by electron microscopy and quantit ... | 1979 | 219611 |
| persistence of herpes simplex virus types 1 and 2 in infected individuals. | during a 23-month period, 18 patients with facial or genital herpetic lesions were examined; culture specimens from each patient were obtained three times per week for virologic studies. the isolated viruses were identified, and the average duration of herpesvirus in lesions was determined. herpes simplex virus type 1 (hsv-1) was isolated from facial lesions for a mean duration of 3 1/2 days. in contrast, herpes simplex virus type 2 (hsv-2) was isolated from genital lesions for a mean duration o ... | 1979 | 219784 |
| application of antisera to interferon in studying oncogenic viruses. | susceptibility of balb/c mice to infection with moloney sarcoma virus (msv) and to herpes simplex virus type 2 (hsv-2) was considerably increased by administration of sheep anti-mouse interferon (anti-if) serum. the regression of the msv-induced tumors was inhibited when the weanling (three-to-four-week-old) mice were injected with the anti-if serum. using the anti-if serum it has been found that the antagonism between hsv-2 and rauscher leukemia virus in the mouse is not mediated by interferon. ... | 1978 | 219809 |
| herpes simplex virus isolation from pyoderma gangrenosum lesions in a patient with chronic lymphatic leukemia. | herpes simplex virus type 2 was isolated and identified from the vesicular border of pyoderma gangrenosum lesions on the genital region of a patient with chronic lymphatic leukemia. dramatic relief of pain as well as quick disappearance of the vesicular margin of the lesions and of the inflammatory halo around them occurred as a result of local treatment with a solution of zinc acetate. a careful search for a viral agent should be done in every case of pyoderma gangrenosum occurring in a patient ... | 1979 | 220109 |
| evaluation of indirect hemagglutination and its inhibition in the differentiation between antibodies to herpes simplex virus types 1 and 2 for seroepidemiologic studies: use of a ii/i index threshold of 85 and an assay of type-specific antibodies. | two parameters, a ii/i index threshold value of 85 and an assay of type-specific antibodies to herpes simplex virus type 1 (hsv-1) and type 2 (hsv-2), were assessed, for seroepidemiologic purposes, for their efficacy in the establishment of past infections with hsv-1 and hsv-2 as indicated by the results of tests for indirect hemagglutination and its inhibition. neither criterion alone established past infection with either hsv-1 or hsv-2. however, by combination of the two parameters, antibodie ... | 1979 | 220339 |

| analysis of herpes simplex virus low molecular-weight native proteins by polyacrylamide gel electrofocusing. | this communication has demonstrated the potential application of gel electrofocusing for the isolation and further characterization of hsv-2 native proteins. at least eight major hsv-2 specific proteins with characteristic isoelectric points could be reproducibly resolved by gel isoelectric focusing. their isoelectric points ranged from 5.0 to 7.5 and analysis by two-dimensional electrophoresis on sds gels indicated that their molecular weights range from 11,000 to 49,000. | 1978 | 221328 |
| the use of intertypic recombinants for analysis of gene organization in herpes simplex virus. | analysis of the dna sequence arrangement and polypeptides specified by 28 hsv-1 x hsv-2 recombinants show the following: (i) recombinants with heterogeneous l and s components or with heterogenous inverted repeats are viable. (ii) hsv-1 and hsv-2 genes appear to be functionally equivalent and with few exceptions co-linearly arranged. co-linear dna maps have been established. (iii) at most two arrangements of hsv dna are capable of replication. this is consistant with current studies suggesting t ... | 1978 | 221347 |

| mapping of the herpes simplex virus dna sequences in three herpes simplex virus thymidine kinase-transformed cell lines. | we have made use of a novel filter hybridization approach in order to map the herpes simplex virus (hsv) dna sequences which are present in three hsv thymidine kinase (tk)-transformed cell lines. the cell line 33a+ which was produced by infection of 3t3 tk- cells with uv-irradiated hsv-2 (333) was found to contain one contiguous stretch of viral dna sequences which maps between 0.15 and 0.57 on the hsv-2 genome. the sequences mapping from 0.31 to 0.37 were present in 3--4-fold higher abundance t ... | 1978 | 221351 |
| dna-mediated transfer of herpes simplex virus tk gene to human tk- cells: properties of the transformed lines. | human tk- cells carrying the hsv-2 tk gene express a tk activity of viral origin and maintain the tk+ phenotype when grown in hat medium. under non-selective or counterselective conditions, however, reversion to a tk- phenotype occurs with a significant frequency characteristic of each transformed line. the tk- phenotype appears to be stable since no instances of tk- to tk+ reversion have been observed. | 1978 | 221353 |
| enhanced efficiency of transfection of hsv dna in hsv-1 dna-transformed hamster cells. | the efficiency of transfection, i.e., the number of plaques per microgram of dna, was compared for herpes simplex virus (hsv) type 1 and type 2, and herpesvirus eidolon (antigenically unrelated to hsv) dnas in hsv dna-transformed cells (eh/a44) and control hamster cells (eht). the efficiency of transfection of hsv-1 and hsv-2 dnas was significantly higher in eh/a44 cells than in eht cells, showing that an early step in hsv infection was involved in the partial resistance of hsv dna-transformed c ... | 1978 | 221357 |
| interferon in the replication of herpes simplex virus in normal and pathological nerve cells. | previous results obtained in experimental and clinical trials have demonstrated that topical combined thrapy with human interferon (hi) and human colostral secretory immunoglobulin a (s-iga) is effective against herpetic corneal infection. this therapy prevented encephalitis in rabbits but could not completely prevent recurrences either in rabbits or in patients. a number of in vitro studies were designed to elucidate the role of these factors in herpes simplex virus replication in the nervous s ... | 1978 | 221373 |
| immune responses to vaginal or systemic infection of mice with herpes simplex virus type 2. | relationships among cell-mediated immune (cmi) responses, neutralizing antibody, and macrophages in host resistance to vaginal or systemic infection with hsv-2 were defined in balb/c mice. the importance of t-lymphocytes in resistance to either systemic or vaginal infection was demonstrated by increased susceptibility of mice depleted of t-lymphocytes. a role for non-specific resistance against the systemic, but not vaginal, infection was demonstrated by increased susceptibility of mice depleted ... | 1978 | 221400 |

| preliminary studies of the mode of action of arildone, a novel antiviral agent. | arildone (also known as win 38020), a novel aryl diketone, inhibited replication of herpes simplex virus type 2 in tissue culture by interfering with an event that occurs prior to 6 h postinfection. the inhibition could be partially reversed by washing. although the exact mechanism of action is unknown, neither viral deoxyribonucleic acid nor viral proteins were synthesized in the presence of arildone. | 1979 | 224808 |
| presence of herpes simplex virus type 2 dna in hamster cells oncogenically transformed by ultraviolet-inactivated virus. | herpes simplex virus type 2 (hsv-2) dna has been detected by molecular hybridization in hamster fibroblast cells oncogenically transformed by ultraviolet-irradiated virus. at early passages after cloning in soft agar, about 40% of the hsv-2 genome was present in all the transformed cell lines at one to six copies per cell. in cell lines derived from tumors induced by these cells, the same percentage of the hsv-2 genome was also found with more uniform number of copies (between two and three). th ... | 1979 | 224988 |
| lymphocyte transformation for the detection of herpesvirus-induced tumor-associated antigens. | cell-mediated immunity to fibroblasts transformed by herpes simplex virus type 2 was investigated with a lymphocyte assay system. the assay system was first standardized with phytohemagglutinin, a nonspecific stimulator of blastogenesis. hamster splenic and blood lymphocytes reacted to phytohemagglutinin with a dose-response curve similar to that reported for other rodent species. splenic lymphocytes from hamsters bearing isografts, induced by herpes simplex virus type 2, were transformed by cel ... | 1979 | 225013 |
| phosphorylation of arabinofuranosylthymine in non-infected and herpesvirus (tk+ and tk-)-infected cells. | the phosphorylation of arabinofuranosylthymine (arathd) has been studied both in non-infected cells and in those infected with herpes simplex virus (hsv-1, lennette; hsv-1, ies and hsv-2, d-316). in these experiments, hsv strains were used which either contain (lennette, tk+ and d-316 tk+) or lack (ies, tk-) the capacity to induce pyrimidine deoxyribonucleoside kinase. it was found that extracellularly administered arathd is phosphorylated to ara ttp via aratmp and aratdp in both non-infected an ... | 1979 | 225422 |
| neoplastic transformation of cultured syrian hamster embryo cells by dna of herpes simplex virus type 2. | syrian hamster embryo cells were transformed to a neoplastic phenotype after exposure to herpes simplex virus type 2 (s-1) dna at concentrations (less than or equal to 0.01 microgram per 60-mm dish) at which infectivity was no longer demonstrable. transformed cells manifested in vitro phenotypic properties characteristic of the neoplastic state, expressed herpes simplex virus-specific antigens, and induced invasive tumors in vivo. transfection and transformation of syrian hamster embryo cells wi ... | 1979 | 225525 |
| physical mapping of paar mutations of herpes simplex virus type 1 and type 2 by intertypic marker rescue. | mutations (paar) in herpes simplex virus (hsv) which confer resistance to phosphonoacetic acid involve genes associated with virus-induced dna polymerase activity. two mutants of hsv (hsv-1 tsh and hsv-2 ts6) produce a thermolabile dna polymerase activity. in this study, the ts lesions present in these mutants and those present in two independent phosphonoacetic acid-resistant mutants of hsv-1 and hsv-2 (paar-1 and paar-2) have been physically mapped by restriction endonuclease analysis of recom ... | 1979 | 225553 |

| production of tubular structures in vero cells infected with herpes simplex virus type 2; effects of ultraviolet light irradiation and antimetabolites. | in order to investigate the nature of tubular structures specifically found in herpes simplex virus type 2 (hsv-2)-infected cells, the multiplication of hsv-2 was studied in vero cells cultured in the presence of varying concentrations of cytosine arabinoside (ara-c) and cycloheximide (ch), inhibitors of dna synthesis and protein synthesis respectively. ara-c, at a concentration of 60 micrograms/ml, inhibited the multiplication of hsv-2 by more than 99% and also prevented the appearance of tubul ... | 1979 | 228001 |
| dnase induced after infection of kb cells by herpes simplex virus type 1 or type 2. ii. characterization of an associated endonuclease activity. | purified preparations of the "exonuclease" specified by herpes simplex virus type 1 (hsv-1) and type 2 (hsv-2) possess an endonuclease activity. the exonuclease and endonuclease activities copurify and cosediment in a sucrose density gradient. endonuclease activity is only observed in the presence of a divalent cation, and mg(2+) or mn(2+) is equally effective as a cofactor with an optimal concentration of 2 mm. a slight amount of endonuclease activity is observed in the presence of ca(2+), wher ... | 1979 | 228069 |

| regulation of persistent infection with herpes simplex virus in vitro by hydrocortisone. | about 1% of raji cells showed sensitivity to herpes simplex virus type 2 (hsv-2) infection when tested by infectious center assays or immunofluorescence tests, and the percentage did not change during cell passage. the addition of hydrocortisone to raji cells persistently infected with hsv-2 caused a marked increase in virus production and in the number of hsv-producing cells. in the case of hsv-1, it was shown that the addition of hydrocortisone was required to maintain persistent infection. th ... | 1979 | 229255 |
| alterations in glycosphingolipid patterns in a line of african green monkey kidney cells infected with herpesvirus. | the major glycosphingolipids (gsls) of a line of african green monkey kidney cells (bgm) were characterized as glucosylceramide, lactosylceramide, galactosyl-galactosyl-glucosylceramide, and n-acetylgalactosaminyl-galactosyl-galactosyl-glucosylceramide. neutral gsls accounted for approximately 80% of the total gsls isolated. the predominant gangliosides were n-acetylneuraminyl-galactosyl-glucosylceramide, n-acetylgalactosaminyl-n-acetylneuraminyl-galactosyl- glucosylceramide, and galactosyl-n-ac ... | 1979 | 229262 |
| storage and transport of cultures for herpes simplex virus, type 2. | tryptic soy broth and brain-heart infusion broth maintained herpes simplex virus within +/- 1 serial dilution of the original titer in all of 51 samples held for one to three days at 4 c. in contrast, holding temperatures of -20 c or 22 c resulted in losses of titer of 10(2) or more. holding periods as long as five days prior to inoculation did not delay the appearance of the cytopathic effect following inoculation. unmodified tryptic soy broth or brain-heart infusion broth and holding periods a ... | 1979 | 229726 |
| effects of antimetabolites on the production of tubular structures in vero cells infected with herpes simplex virus type 2. | treatment of vero cells infected with herpes simplex virus type 2 with the proper concentrations of hydroxyurea (hu) reduced the production of infectious virus and markedly increased the accumulation of tubular structures in the nuclei when the drug was added within 6 hours after infection. similar accumulation of tubular structures in the infected nuclei was also observed when infected cells were treated with phosphonoacetic acid at proper concentrations. the release of hu-treated, herpes simpl ... | 1979 | 229802 |
| isolation of the major herpes simplex virus type 1 (hsv-1)-specific glycoprotein by hydroxylapatite chromatography and its use in enzyme-linked immunosorbent assay for titration of human hsv-1-specific antibodies. | a 131,000 molecular weight herpes simplex virus type 1 (hsv-1) glycoprotein designated antigen number 6 (ag-6) was previously shown to possess almost exclusively hsv-1-specific antigenic sites. fused rocket and crossed immunoelectrophoresis of fractions obtained from hydroxylapatite chromatography of crude hsv-1 antigen (triton x-100-solubilized, infected tissue culture cells) showed that a subfraction of ag-6 could be separated from the other hsv antigens. enzyme-linked immunosorbent assay with ... | 1979 | 230199 |
| reactivation of herpes simplex virus type 2 from a quiescent state by human cytomegalovirus. | the ability of human cytomegalovirus to stimulate replication of herpes simplex virus type 2 (hsv-2) was examined. the system used involved hsv-2-infected human embryonic lung cells under conditions (39.5-40 degrees c) in which hsv-2 remains undetectable. reactivation of hsv-2 was maximal and persisted for the longest duration when cultures were superinfected with 0.02 plaque-forming unit of human cytomegalovirus per cell. infectious hsv-2 appeared 2 days after superinfection with human cytomega ... | 1979 | 230494 |
| growth inhibition by acycloguanosine of herpesviruses isolated from human infections. | inhibition by acycloguanosine (acg) of plaque formation by harpes simplex virus types 1 and 2 (hsv-1 and hsv-2), varicella-zoster virus, and cytomegalovirus was studied. seventeen clinical isolates of hsv-1 were inhibited by acg at a mean 50% inhibitory dose (id(50)) of 0.15 +/- 0.09 mum. the mean id(50) for 10 isolates of hsv-2 was 1.62 +/- 0.76 mum, and for four isolates of varicella-zoster virus it was 3.75 +/- 1.30 mum. the id(50)'s for two cytomegalovirus isolates were 100 and 160 mum, and ... | 1979 | 230783 |
| [epidemiology of carcinoma of the cervix (author's transl)]. | in order to explain why modes of sexual life influence the incidence of cervical carcinoma, several factors have been claimed to be involved. there is no solid basis for the hypothesis that sperm may be mutagenic. by contrast, epidemiological studies showed that partners whose life is not sedentary bring back home to their wives an increased risk of cervical carcinoma. the infectious factor does not seem to be associated with syphilis but may well be represented by herpes genitalis virus (herpes ... | 1979 | 230875 |
| host-cell response to herpes virus infection in central and peripheral nervous tissue in vitro. | in an organotypic nerve cell culture system, all cells in both the central and the peripheral nervous system (cns, pns) components supported replication of herpes simplex virus types 1 and 2 (hsv 1, hsv 2). in hsv 1 infection, cellular response was particularly characterized by the formation of small syncytia (which involved neurons) and by the presence of bundles of interwoven fine filaments within the nuclei of infected cells. in hsv 2 infection, groups of parallel tubules characteristically f ... | 1979 | 231090 |
| blocking of acid-fixed nuclear binding of epstein-barr virus nuclear antigen (ebna) by different dna species. | treatment of epstein-barr virus-determined nuclear antigen (ebna) with dna resulted in blocking of its ability to convert acid-fixed ebna-negative cell nuclei to an ebna-positive form. epstein-barr virus (ebv) dna, herpes simplex virus type 2 (hsv-2) dna and dna isolated from three lymphoblastoid cell lines differed in their potency to block this reaction. ebv dna was found to be about three times more effective than cellular dnas in abolishing the ability of dna-cellulose-purified ebna to conve ... | 1979 | 231093 |
| the presence of herpes simplex virus dna in hamster embryo cells transformed by a temperature sensitive mutant, ts-4. | hamster embryo cells transformed with a temperature sensitive mutant of hsv-2, ts-4t, were examined for the presence of viral genomes. dna-dna reassociation kinetics showed that only a small portion (11 +/- 4%) of hsv-2 was present in the transformed cells. | 1979 | 231439 |
| comparative study of herpes group virus-induced dna polymerases. | a comparative biochemical study of virus-induced dna polymerases was made among the herpes group viruses: namely, herpes simplex virus (hsv) type 1 and type 2, human cytomegalovirus (hcmv) and varicella-zoster virus (vzv). although these virus-induced enzymes shared some biochemical properties, they differed in several important aspects. all these virus-induced dna polymerases could efficiently use poly(dc) . oligo(dg)12--18 and poly(da) . oligo(dt)12--18 as template-primers. however, in phospho ... | 1979 | 231586 |
| tumorgenicity of herpesvirus hominis type 2-transformed cells (line 333-8-9) in adult hamsters. | inoculation of adult hamsters with greater than 1.5 x 10(2) herpesvirus type 2 (hsv-2) transformed hamster embryo fibroblasts induced rapidly growing tumours at the site of inoculation, in more than 50 per cent of animals. the tumours were examined by light and electron microscopy, and were histologically anaplastic fibrosarcomas. lung metastases were frequently found in tumour-bearing animals; these were usually only seen microscopically, and were cytologically similar to the primary tumours. t ... | 1979 | 231649 |
| serological studies on the antigenic relationship between herpes simplex virus and varicella-zoster virus. | if crossreacting antibodies between varicella-zoster virus (vzv) and herpes simplex virus (hsv) exist, one would expect more positive reactions with vzv in a group of hsv positive patients than in a group of hsv negative patients. this statement can only apply to a group of individuals where positive and negative reactions with respect to hsv and vzv are evenly distributed. such a distribution can only be found among children. therefore, the relationship between hsv-1 and vzv was the only one wh ... | 1979 | 232073 |
| phosphorylation of a ribosomal protein and of virus-specific proteins in cells infected with herpes simplex virus. | in cells infected with herpes simplex virus a protein associated with the small subunit of ribosomes became phosphorylated. it was not detectably labelled with 14c-amino acids added after infection and is therefore probably a cellular protein. the phosphorylated ribosomal proteins from hsv-1- and hsv-2-infected cells were indistinguishable electrophoretically and had an apparent mol. wt. of about 48 000. phosphorylation of the 48k protein was detected 2 to 3 h after infection and reached a maxim ... | 1979 | 232130 |
| virus-specific dna sequences present in cells which carry the herpes simplex virus thymidine kinase gene. | two independently derived cell lines which carry the herpes simplex type 2 thymidine kinase gene have been examined for the presence of hsv-2-specific dna sequences. both cell lines contained 1 to 3 copies per cell of a sequence lying within map co-ordinates 0.2 to 0.4 of the hsv-2 genome. revertant cells, which contained no detectable thymidine kinase, did not contain this dna sequence. the failure of ecor1-restricted hsv-2 dna to act as a donor of the thymidine kinase gene in transformation ex ... | 1979 | 232133 |
| mutant of herpes simplex virus type 2 with temperature-sensitive lesions affecting virion thermostability and dnase activity: identification of the lethal mutation and physical mapping of the nuc-lesion. | we had previously shown that a temperature-sensitive (ts) mutant of herpes simplex virus type 2 strain hg52, ts13, induced a heat-labile dnase activity in infected cells (b. francke, h. moss, m. c. timbury, and j. hay, j. virol. 26:209-213, 1978). earlier work indicated that the mutant also possessed temperature-sensitive infectivity (i. w. halliburton and m. c. timbury, j. gen. virol. 30:207-221, 1976). in this study temperature-stable revertants of ts13 have been isolated; examination of them ... | 1979 | 232166 |
| [seroepidemiological study of herpes simplex virus type 2 in adult women of costa rica]. | the frequency of genital herpes simplex type 2 infections in a group of twenty adult costa rican women was studied by isolation of the virus and the measurement of neutralizing antibody activity in sera. the virus could not be isolated in any of the vaginal secretions. neutralizing antibody activity to herpes virus types 1 and 2 was found in sera from sixteen subjects. an antibody ii/i index equal to or larger than 87, indicative of infection with herpes simplex type 2 was found in fifty per cen ... | 1979 | 233038 |
