determination of herpes simplex virus type-specific antibodies by enzyme-linked immunosorbent assay. | we determined type-specific antibodies to herpes simplex virus type 1 (hsv-1) and type 2 (hsv-2) by an indirect enzyme-linked immunosorbent assay, using as antigens hsv-1 glycoprotein gc-1 and a hsv-2-specific polypeptide purified on affinity columns of monoclonal antibodies. all sera were initially screened for hsv antibodies by the enzyme-linked immunosorbent assay with a pool of triton x-100-extracted antigens of hsv-1- and hsv-2-infected hep-2 cells. the titer of hsv antibodies was predicted ... | 1983 | 6311871 |
correlation between low natural killing of fibroblasts infected with herpes simplex virus type 1 and susceptibility to herpesvirus infections. | natural killer cells capable of lysing herpes simplex virus type 1 (hsv-1)-infected fibroblasts were studied in three groups of patients unusually susceptible to severe herpes-virus infections. cord blood was evaluated because of the known susceptibility of neonates to disseminated infections due to herpes simplex virus type 2 at birth. only 30% of the cord blood specimens tested demonstrated normal lysis of hsv-1-infected fibroblasts and a normal increment in the lysis of infected over uninfect ... | 1983 | 6304202 |
herpes simplex virus-induced ribonucleotide reductase: development of antibodies specific for the enzyme. | we have previously reported on the characterization of a novel ribonucleotide reductase induced in herpes simplex virus type 2 (hsv-2)-infected mammalian cells. the virus-induced enzyme was partially purified, free of the constitutive cell isozyme, by fractionation of infected cell extracts with ammonium sulphate. in this report we describe a further purification of the virus-induced enzyme and the development of a rabbit antiserum capable of specifically inhibiting its activity. enzymically act ... | 1983 | 6304235 |
nucleotide sequence of the herpes simplex virus type 2 thymidine kinase gene. | we have determined the complete nucleotide sequence of the thymidine kinase gene of herpes simplex virus (hsv) type 2 strain 333. the sequence of the thymidine kinase gene exhibits an open translational reading frame of 1,128 nucleotides encoding a protein of 376 amino acids. the dna sequence was compared with that of the hsv type 1 thymidine kinase gene from strain mp (s. l. mcknight, nucleic acids res. 8:5949-5964, 1980) and from strain cl 101 (m. j. wagner, j. a. sharp, and w. c. summers, pro ... | 1983 | 6304336 |
neoplastic transformation by a cloned human cytomegalovirus dna fragment uniquely homologous to one of the transforming regions of herpes simplex virus type 2. | specific dna fragments of human cytomegalovirus strain towne exhibited sequence homology to the transforming regions of herpes simplex virus type 2 (hsv-2) when examined by nitrocellulose filter hybridization under nonstringent conditions. cloned towne xba i fragments b and c were homologous to both bgl ii transforming fragments n and c of hsv-2 dna, whereas cloned towne xba i fragment e was uniquely homologous to hsv-2 bgl ii fragment c. furthermore, towne xba i fragment e exhibited homology to ... | 1983 | 6304741 |
herpes simplex virus and human cancer. iii. search for relationship of herpes simplex antibodies and cervical dysplasia and labial neoplasia. | we employed the enzyme-linked immunosorbent assay (elisa), indirect hemagglutination (iha), and complement fixation (cf) methods to measure antibody titer to herpes simplex virus type 1 (hsv-1) and type 2 (hsv-2) in patients affected by labial tumors or cervical dysplasias. no relationship of antibody titer to hsv-1 and labial tumors was detected by any of the three methods. association between antibody titer to hsv-2 and cervical dysplasias was revealed by iha (p less than 0.05) and elisa (p le ... | 1983 | 6304957 |
a novel method for determining the sensitivity of herpes simplex virus to antiviral compounds. | a rapid and sensitive assay was developed to analyse the sensitivity of wild type hsv-1 and hsv-2 isolates with respect to a battery of antiviral substances. in the viral sensitivity assay, human embryonic lung fibroblasts are incubated with the virus isolate and different concentrations of the antivirals. after 1-3 days, the cells are disrupted and analysed for hsv type 1 or 2 antigens by an enzyme-linked immunosorbent assay. antigens corresponding to 17 plaque-forming units were detectable aft ... | 1983 | 6306030 |
9-([2-hydroxy-1-(hydroxymethyl)ethoxy]methyl)guanine: a selective inhibitor of herpes group virus replication. | 9-([2-hydroxy-1-(hydroxymethyl)ethoxy]methyl)guanine (2'-nor-2'-deoxyguanosine; 2'ndg) selectively inhibits the replication of herpes group viruses. in cell culture studies 2'ndg was at least 10-fold more potent than acyclovir (acv) in inhibition of human cytomegalovirus replication and epstein-barr virus-induced lymphocyte transformation and was about as effective as acv in inhibition of herpes simplex viruses 1 and 2 and varicella zoster virus. orally administered 2'ndg was 6- to 50-fold more ... | 1983 | 6306664 |
sexual and socioeconomic factors affecting the risk of past infections with herpes simplex virus type 2. | between november 1978 and may 1980, a cross-sectional survey of 566 females and 391 males, aged 35 to 50 years, living in metropolitan toronto, was conducted to examine the influence of socioeconomic status and sexual behavior on the occurrence of antibodies to herpes simplex virus type 2. antibodies to the virus were detected in 17.5% of females and 12.8% of males. lower socioeconomic status was associated with an increased risk of herpes simplex virus type 2 seropositivity for females but not ... | 1983 | 6307043 |
monoclonal antibodies for rapid diagnosis and typing of genital herpes infections during pregnancy. | fluorescein-conjugated, type-specific monoclonal antibodies to herpes simplex virus (hsv-1 and hsv-2) and group-specific antibody which recognizes both hsv-1 and hsv-2 were used to detect hsv-infected cells in clinical specimens. specimens were collected from 66 pregnant women with a past history of herpes genitalis or with suspected lesions. fourteen of 18 samples from which virus was isolated were positive by immunofluorescence test; four of 18 specimens had an insufficient number of cells (le ... | 1983 | 6307053 |
susceptibility of recent clinical isolates of herpes simplex virus to 5-ethyl-2'-deoxyuridine: preferential inhibition of herpes simplex virus type 2. | we examined the in vitro susceptibilities of three reference strains and 41 recent clinical isolates of herpes simplex virus types 1 and 2 to 5-ethyl-2'-deoxyuridine. this thymidine analog exerts a type 2-preferential but not a type 2-specific antiviral effect. utilizing a microtiter assay with bhk-21 cells, we found that the mean (+/- standard deviation) 50% inhibitory dose for herpes simplex virus type 1 isolates was 0.58 +/- 0.30 micrograms/ml as compared with 0.33 +/- 0.20 microgram/ml for h ... | 1983 | 6307130 |
antiviral activity of the 3'-amino derivative of (e)-5-(2-bromovinyl)-2'-deoxyuridine. | 3'-nh2-bv-durd, the 3'-amino derivative of (e)-5-(2-bromovinyl)-2'-deoxyuridine, was found to be a potent and selective inhibitor of herpes simplex virus type 1 (hsv-1) and varicella-zoster virus (vzv) replication. 3'-nh2-bv-durd was about 4-12 times less potent but equally selective in its anti-herpes activity as bv-durd. akin to bv-durd, 3'-nh2-bv-durd was much less inhibitory to herpes simplex virus type 2 than type 1. it was totally inactive against a thymidine kinase-deficient mutant of hsv ... | 1983 | 6307280 |
detection in antisera of antibodies that cross-react with herpes simplex virus type 1 glycoprotein gc. | herpes simplex virus type 1 (hsv-1) glycoprotein gc was purified by affinity chromatography with an immunosorbent column containing monoclonal antibody to hsv-1 gc, and its reactivity with rabbit antisera was measured by enzyme-linked immunosorbent assay and sodium dodecyl sulfate-polyacrylamide gel electrophoretic analysis of radioimmunoprecipitates. positive reactions were detected between hsv-1 gc and rabbit hyperimmune antisera to both hsv-1 and hsv-2. electrophoretic analysis also revealed ... | 1983 | 6307870 |
blocked herpes simplex virus type 2-specific dna synthesis in simian virus 40-transformed hamster cells permissive for herpes simplex virus type 1. | simian virus 40-transformed hamster cells (ll-1) permissive to herpes simplex virus type 1 (hsv-1) were shown to be relatively nonpermissive to hsv-2. when ll-1 cells were infected with hsv-2, there was a 3- to 4-log reduction in infectious viral progeny at 24 h postinfection as compared with hsv-1 under identical cultured conditions. hsv-2 could be carried in the ll-1 cell line for up to 12 passages without any appreciable cytopathology. various early functions of the replicative cycle of hsv-2 ... | 1983 | 6307875 |
colonization of murine ganglia by a superinfecting strain of herpes simplex virus. | we report on the colonization of murine trigeminal ganglia after sequential infection of mice by herpes simplex viruses (hsvs). in preliminary studies, we have established that whereas the hsv-1(f) strain efficiently colonizes ganglia when inoculated by either the ear or eye routes, the hsv-1 x hsv-2 recombinant c7d colonizes ganglia when inoculated by the eye route only. the experimental design consisted of inoculating the right eye with c7d on day 1 and with hsv-1(f) in both left and right eye ... | 1983 | 6307880 |
replication at body temperature selects a neurovirulent herpes simplex virus type 2. | a prototype strain of herpes simplex virus type 2 (hg-52) replicated at 31 degrees c was avirulent when inoculated intracranially into mice. this property was not altered after serial passage of the agent at 31 degrees c, but the virus became virulent after passage at 37.5 degrees c. the selection was not merely for an agent which replicated more efficiently at the higher temperature, but for viruses with enhanced capacity to replicate in the brains of mice. virulent descendants of plaque-purifi ... | 1983 | 6307887 |
an elisa technique to detect igg antibody to the early herpes simplex virus type 2 (hsv-2) antigen ag-4 in hsv-2 patients. | an elisa system, based on urease activity was used for the detection and titration of igg to the immediate early ag-4 antigen in sera from hsv-2 patients. it detected low levels of igg to the ag-4 antigen in 32% of patients' sera known to contain complement fixing antibody to the antigen. furthermore, the sensitivity of the elisa system was 2- to 10-fold higher than the complement-fixation system depending on when the sera was taken from the hsv-2 patients. the system also allowed the easy detec ... | 1983 | 6308025 |
the use of monoclonal antibodies in (reverse) passive haemagglutination tests for herpes simplex virus antigens and antibodies. | three monoclonal antibodies against herpes simplex virus type 2 have been tested for their suitability as reagents in reverse passive haemagglutination. two of these antibodies with specificity for virus glycoprotein d, when linked to red blood cells, were able to capture antigens without being agglutinated, but addition of immune serum subsequently led to agglutination. haemagglutination using these monoclonal antibody-linked, antigen-captured red cells was readily applicable to testing human s ... | 1983 | 6308140 |
phase i evaluation of 2'-fluoro-5-iodo-1-beta-d-arabinofuranosylcytosine in immunosuppressed patients with herpesvirus infection. | 2'-fluoro-5-iodo-1-beta-d-arabinofuranosylcytosine (fiac) is a potent selective inhibitor of the replication of herpes simplex virus types 1 and 2 (hsv-1, hsv-2), varicella zoster virus, and cytomegalovirus in cell culture systems. fiac produces an unequivocal therapeutic effect in mice that have been inoculated with a lethal burden of hsv-1. we have administered fiac to 32 host compromised patients, 30 with advanced cancer, who were experiencing acute herpesvirus infections (varicella zoster, 2 ... | 1983 | 6309380 |
the effect of cycloheximide on the accumulation and stability of functional alpha-mrna in cells infected with herpes simplex virus. | cells were infected with herpes simplex virus type 2, hsv-2(g), and incubated in the presence of cycloheximide (cx). when cx was removed and actinomycin d (act d) added, alpha-polypeptides icp 0 and icp 4 were synthesized at low rates. if cx was removed without adding act d, the rate of production of icp 4 increased while that of icp 0 remained constant. in cells treated with azetidine to enhance the production of icp 4 and 0, accumulation of functional mrna for icp 4 (determined indirectly by t ... | 1983 | 6310035 |
localization of the coding region for a 35000 dalton polypeptide on the genome of herpes simplex virus type 2. | the cloned bglii n fragment of herpes simplex virus type 2 (hsv-2) dna has been shown to code for a 35k polypeptide. subfragments made by cleavage with xhoi, bamhi, sstii and xorii were then cloned and used with rna extracted from hsv-2-infected cells for mrna selection and in vitro protein synthesis. we found that the major translation product of such hybrid-selected mrna has a molecular weight of 35 000. by further mapping, dna coding sequences for this mrna were located within the region of b ... | 1983 | 6310044 |
nucleotide sequence of the herpes simplex virus type 2 (hsv-2) thymidine kinase gene and predicted amino acid sequence of thymidine kinase polypeptide and its comparison with the hsv-1 thymidine kinase gene. | to analyze the boundaries of the functional coding region of the hsv-2(333) thymidine kinase gene (tk gene), deletion mutants of hybrid plasmid pmar401 h2g, which contains the 17.5 kbp bglii-g fragment of hsv-2 dna, were prepared and tested for capacity to transform lm(tk-) cells to the thymidine kinase-positive phenotype. these studies showed that hybrid plasmids containing 2.2-2.4 kbp subfragments of hsv-2 bglii-g dna transformed lm(tk-) cells to the thymidine kinase-positive phenotype and sug ... | 1983 | 6317035 |
intranuclear distribution of herpes simplex virus type 2 dna synthesis: examination by light and electron microscopy. | uptake of [3h]thymidine by serum-starved baby hamster kidney cells infected with herpes simplex virus type 2 was investigated by light microscopic and electron microscopic autoradiography. the distribution of incorporated label altered throughout the period of viral dna synthesis. it was restricted initially to a few well-defined sites within the nucleus which increased in size and spread as infection proceeded until the entire nucleus was involved. the label was not associated with any identifi ... | 1983 | 6310045 |
immortalization and neoplastic transformation of normal diploid cells by defined cloned dna fragments of herpes simplex virus type 2. | diploid syrian hamster embryo (she) cells were passaged after transfection with recombinant plasmids containing herpes simplex virus type 2 (hsv-2) dna inserts bgl ii focus-forming fragment n, bgl ii transforming fragment c, and ecori/hindiii fragment ae. cultures transfected with salmon dna or with 0.1-5.0 micrograms of bgl ii fragment n reached crisis and senesced. those transfected with 0.1-0.5 micrograms of bgl ii fragment c or its left-hand 64% subclone ecori/hindiii fragment ae escaped sen ... | 1983 | 6310602 |
activity of 1-(2'-fluoro-2'-deoxy-beta-d-arabinofuranosyl)thymine against herpes simplex virus in cell cultures and rabbit eyes. | a new antiviral compound 1-(2'-fluoro-2'-deoxy-beta-d-arabinofuranosyl)thymine (2'-fluoro-5-methyl-ara-uracil [fmau]), was compared with acyclovir and idoxuridine in vitro against two strains of both herpes simplex virus type 1 (hsv-1) and hsv-2. determinations of the 50% effective dose varied slightly with each strain and with the host cells employed. the 50% effective dose for fmau and acyclovir against hsv-1 ranged from 0.1 microm to 0.5 to 0.6 microm in rabbit kidney cells and from 0.5 micro ... | 1983 | 6311085 |
hepatic infection by thymidine kinase-positive and thymidine kinase-negative herpes simplex virus after partial hepatectomy. | herpes simplex virus (hsv) infection of mouse liver after partial hepatectomy was studied. partial hepatectomy resulted in the rapid onset of cellular dna synthesis and the appearance of many mitotic figures (peak, 3 days after surgery). similar changes were not seen in control animals. after partial hepatectomy, the mice were infected with thymidine kinase-positive (tk+) and -negative (tk-) hsv to investigate virus titers in liver tissue during liver cell replication. in control unoperated mice ... | 1983 | 6311750 |
herpes simplex virus non-structural proteins. iv. purification of the virus-induced deoxyribonuclease and characterization of the enzyme using monoclonal antibodies. | the alkaline nucleases induced by herpes simplex virus type 1 (hsv-1) and type 2 (hsv-2) have been purified from high salt extracts of virus-infected cells. the purification used three types of column chromatography and resulted in apparently homogeneous dnase preparations with good recovery. the enzyme from hsv-2-infected cells has been characterized. it had both exonuclease and endonuclease activity, each with an unusually high ph optimum. the enzyme had an absolute requirement for magnesium w ... | 1983 | 6311954 |
inhibition by acyclovir of herpes simplex virus type 2 morphologically transformed cell growth in tissue culture and tumor-bearing animals. | rat embryo fibroblasts (ref) morphologically transformed by herpes simplex virus type 2 (hsv-2) and tumor-derived cells were tested for ability to grow in the presence of 9-(2-hydroxyethoxymethyl) guanine (acyclovir). results indicated that the effective dose of acyclovir (acv) required to inhibit hsv-2-transformed and tumor-derived cell growth by 50% (ed50) compared to mock-treated control cells averaged 15 to 75 micrograms/ml. in contrast, the ed50 of acyclovir was more than hep-2 cells. hsv-2 ... | 1983 | 6311971 |
insertion mutants of herpes simplex virus have a duplication of the glycoprotein d gene and express two different forms of glycoprotein d. | we produced insertion mutants of herpes simplex virus (hsv) that contain two functional copies of genes encoding different forms of glycoprotein d (gd). these viruses have the gene for hsv type 2 (hsv-2) gd at the normal locus and the gene for hsv-1 gd inserted into the thymidine kinase locus. results of immunoprecipitation experiments done with monoclonal antibodies revealed that both gd genes were expressed by these viruses, regardless of orientation of the inserted hsv-1 gd gene, and that max ... | 1983 | 6312097 |
effect of phosphonoformate on symptomatic genital herpes simplex virus type 2 infection of guinea pigs. | using a guinea pig model of genital herpes simplex virus (hsv) type 2 infection, phosphonoformate treatment initiated after the onset of symptoms had a therapeutic effect on the outcome of disease. severity of disease, viral shedding, and hsv-induced cellular changes in vaginal cytology were significantly reduced in drug-treated animals as compared to sham-treated animals, although virus was readily detected in the nervous system of animals from both groups. the percentage of animals harboring l ... | 1983 | 6298142 |
induction of a latent herpes simplex virus from a rat tumour initiated by herpes simplex virus-transformed cells. | a rat tumour induced by cells transformed with the sheared dna of herpes simplex virus (hsv) type 1 hfem alpha (re2a) was injected with the intertypic virus hsv-2 hg52 ts 1. separate plaques, isolated from cocultivation of excised tumour tissue with susceptible cells, yielded virus the dna of which had the restriction enzyme profile either of the injected hsv-2 virus or that of the hsv-1 virus, originally used to transform the cells. no evidence of in vivo recombination was detected. in hooded l ... | 1983 | 6298356 |
inversion of the two segments of the herpes simplex virus genome in intertypic recombinants. | we have analysed by restriction site mapping the structures of the termini and l-s joint in several hsv-1/hsv-2 intertypic recombinants, including bx1(28-1), the virion dna of which has a marked overabundance of one orientation of the l segment, and subclones of bx1(28-1). all recombinants with both orientations of l present in equal amounts contain trl and irl regions derived at least in part from the same parent (hsv-1 or hsv-2) as a result of previously undetected crossovers in these regions. ... | 1983 | 6296294 |
herpes simplex virus types 1 and 2 induce shutoff of host protein synthesis by different mechanisms in friend erythroleukemia cells. | herpes simplex virus type 1 (hsv-1) and hsv-2 disrupt host protein synthesis after viral infection. we have treated both viral types with agents which prevent transcription of the viral genome and used these treated viruses to infect induced friend erythroleukemia cells. by measuring the changes in globin synthesis after infection, we have determined whether expression of the viral genome precedes the shutoff of host protein synthesis or whether the inhibitor molecule enters the cells as part of ... | 1983 | 6296433 |
characterization of herpes simplex virus 2 temperature-sensitive mutants whose lesions map in or near the coding sequences for the major dna-binding protein. | by marker rescue with cloned herpes simplex virus 2 dna fragments, we have mapped the temperature-sensitive mutations of a series of herpes simplex virus 2 mutants to a region of the herpes simplex virus 2 genome that lies within or near the coding sequences for the major dna-binding protein, icp8. in cells infected with certain of these mutants at the nonpermissive temperature, the association of the major dna-binding protein with the cell nucleus was defective. in these cells, the dna-binding ... | 1983 | 6296440 |
herpes simplex virus. an expanding relationship to human cancer. | herpes simplex virus (hsv) causes a wide spectrum of infectious disease in humans. during the past 15 years, evidence has accumulated indicating that, in addition, hsv may be a cause of human cancer, particularly cervical cancer. the research on hsv has taken five directions. first is detection of previous infection with hsv 2. this was the earliest approach and was performed largely with serologic assays. studies showed a higher incidence of infection with hsv-2 in cervical cancer patients as c ... | 1983 | 6300393 |
genetic analysis of temperature-sensitive mutants which define the genes for the major herpes simplex virus type 2 dna-binding protein and a new late function. | eleven temperature-sensitive mutants of herpes simplex virus type 2 (hsv-2) exhibit overlapping patterns of complementation that define four functional groups. recombination tests confirmed the assignment of mutants to complementation groups 1 through 4 and permitted the four groups to be ordered in an unambiguous linear array. combined recombination and marker rescue tests (a. e. spang, p. j. godowski, and d. m. knipe, j. virol. 45:332-342, 1983) indicate that the mutations lie in a tight clust ... | 1983 | 6296441 |
genetic analysis of temperature-sensitive mutants which define the gene for the major herpes simplex virus type 1 dna-binding protein. | we have assigned eight temperature-sensitive mutants of herpes simplex virus type 1 to complementation group 1-1. members of this group fail to complement mutants in herpes simplex virus type 2 complementation group 2-2. the mutation of one member of group 1-1, tsha1 of strain mp, has been shown to map in or near the sequence which encodes the major herpes simplex virus type 1 dna-binding protein (conley et al., j. virol. 37:191-206, 1981). the mutations of five other members of group 1-1 map in ... | 1983 | 6296442 |
[level of cyclic nucleotides (camp and cgmp), atpase activity and calcium ion transport in hamster lymphocytes during tumor growth]. | the biochemical systems of lymphocytes of the peripheral blood and lymph nodes of hamsters with a herpes simplex (type 2) virus--induced transplantable tumor rapp hsv2 were studied. the camp concentration in tumor-bearing hamsters was 1.5-2 times higher, while cgmp level--2.2 times lower than in control. this was matched by a rise in the level of transport atpases in the lymphocytes of experimental animals. concanavalin a had practically no effect on the uptake of ca2+ by lymphocytes of tumor-be ... | 1983 | 6301159 |
molecular genetics of herpes simplex virus. viii. further characterization of a temperature-sensitive mutant defective in release of viral dna and in other stages of the viral reproductive cycle. | previous studies have shown that cells infected with the herpes simplex virus 1(hfem) mutant tsb7 and maintained at the nonpermissive temperature fail to accumulate viral polypeptides. analyses of intertypic recombinants generated by marker rescue of tsb7 with herpes simplex virus 2 dna fragments localized the mutation between 0.46 and 0.52 map units on the viral genome (knipe et al., j. virol. 38:539-547, 1981). in this paper we report that the mutation in tsb7 affects several aspects of the re ... | 1983 | 6296445 |
enhancement of lewis lung carcinoma by the concomitant infection of the host with herpes simplex virus type 1 and type 2. | infection with herpes simplex virus (hsv) enhances the growth of lewis lung tumor (llt). infection with hsv-1 enhances as efficiently as hsv-2. a significant acceleration of primary tumor formation was obtained. in mice, lung metastases were increased in number and size above the controls. enhancement occurred only with high doses of infectious virus and was also obtained only when the virus infection was at a site close to that of the tumor implantation. this finding, in addition to the lack of ... | 1983 | 6296746 |
fatal systemic herpes simplex virus type 2 infection in a healthy young woman. | a previously healthy 28-year-old woman without historic or anatomic evidence of immunologic defect had a genital herpes simplex virus infection that rapidly progressed to systemic disease, with death 12 days after the onset of illness. herpes simplex virus type 2 was isolated from the liver and spleen and was also shown by direct immunofluorescence in the liver and spleen, but not in the brain. we have found no previously reported instance of death from this virus in a young adult uncompromised ... | 1983 | 6297097 |
viral genes modify herpes simplex virus latency both in mouse footpad and sensory ganglia. | herpes simplex virus type 2 wild-type and 13 temperature-sensitive mutants have been examined for their ability to be recovered from latently infected biozzi mice. after inoculation into the rear footpad, virus could be recovered from both the dorsal root ganglia (drg) and the footpad (fp) at the site of inoculation (wt, ts 1, ts 2, ts 4, ts 6, ts 7 and ts 8), or from the drg only (ts 11 and ts 13), or from fp only (ts 3, ts 9, ts 12). two mutants (ts 5 and ts 10) have not been recovered from ei ... | 1983 | 6302212 |
herpes simplex virus non-structural proteins. iii. function of the major dna-binding protein. | the herpes simplex virus type 2 major dna-binding protein has been functionally characterized using temperature-sensitive mutants in the complementation group 2-2. the mutants were shown to be defective in the dna-binding protein gene by mapping the mutants to the area of the genome known to code for the protein, and by demonstrating alterations in the major dna-binding protein induced in mutant-infected cells. the mutants were shown to be defective in the replication of virus dna. the nature of ... | 1983 | 6302216 |
a herpesvirus antigen in human premalignant and malignant cervical biopsies and explants. | cervical biopsies and explant cultures from patients with squamous metaplasia, various grades of dysplasia, carcinoma in situ (cis), and invasive squamous cell carcinoma were screened for vp143, an early nonstructural polypeptide of herpes simplex virus type 2 (hsv-2), vp143 was identified in 31% of biopsies exhibiting severe dysplasia, 29% with cis, and 41% with invasive squamous cell carcinoma. similar results were obtained when explants derived from these biopsies were examined for vp143. the ... | 1983 | 6295165 |
leptomeningitis and polycaryocyte formation in the cns of rats inoculated subcutaneously with herpes simplex virus. | wistar rats were inoculated subcutaneously with either type 1 (hsv1) or type 2 (hsv2) herpes simplex virus at 5 days of age. animals were killed in extremis or at the end of the 14-day observation period postinoculation. acute destructive meningoencephalitis with hemorrhage and leukocytic infiltration was observed in both groups. polycaryocytes comprised of cells of the internal granular layer of the cerebellum were observed in some animals inoculated with hsv1. these multinucleated cells appear ... | 1983 | 6852211 |
viruses and human cancer. | the cause of human cancer is probably multifactorial and the role of viruses is unclear. the study of retroviruses has led to the identification of oncogenes responsible for transformation and tumor induction. human viruses associated with malignancies include the jc virus (associated with progressive multifocal leukoencephalopathy) and some adenoviruses. no human malignancies have been associated with the latter group. a number of herpes viruses of lower animals have been associated with malign ... | 1983 | 6870184 |
changes in the vaginal cytology of the guinea pig induced by herpes simplex virus. | the vaginal cytology of guinea pigs with genital herpes simplex virus type 2 (hsv-2) infection was examined during acute and latent infection. cytologic changes similar to those observed in humans with hsv-2 genital infections were observed in the guinea pigs during acute infection. during latent infection, some animals continued to have abnormal cytology. the severity of the changes was reduced after treatment with phosphonoformic acid during acute infection. | 1983 | 6223477 |
herpes type 2 infection with unusual generalised manifestations and delayed diagnosis in an adult male. | a case of severe generalised herpes simplex type 2 infection is described in an adult male who had known exposure to herpes. the patient first complained of headache, fever and neurological symptoms, and three to six days later of conjunctivitis, severe pharyngitis, arthralgia and vesicular lesions about the body. during the first 14 days of illness, including three in hospital, the patient was diagnosed as having infection with varicella virus, vesicular stomatitis virus, or hand-foot-and-mouth ... | 1983 | 6875292 |
lack of efficacy of amp against recrudescent genital herpes infections in guinea pigs. | amp was evaluated for its efficacy against herpes simplex virus type 2 genital infections in guinea pigs. vaginally infected animals were treated twice a day with amp at 50 mg/kg per dose for 2 weeks. subcutaneous doses were started 10 weeks postinfection. amp treatment did not reduce the number of animals with recrudescent episodes when compared with saline-treated controls. in addition, amp treatment did not reduce either the number of lesions or the duration of the recrudescent episodes which ... | 1983 | 6685993 |
