| dna sequence of the herpes simplex virus type 2 glycoprotein d gene. | we describe a 1635-bp herpes simplex virus type 2 (hsv-2) dna sequence containing the entire coding region of glycoprotein d (gd-2). the amino acid sequence of gd-2, deduced from the nucleotide sequence, was compared to that of the analogous herpes simplex virus type 1 (hsv-1) glycoprotein (gd-1). the two glycoproteins are 85% homologous and contain highly conserved regions of as much as 49 amino acids in length. comparison of dna sequences upstream from gd-1 and gd-2 coding regions identified p ... | 1983 | 6323270 |
| detection of herpes simplex virus intertypic recombinant genomes in infected cell dna. | intertypic recombination between herpes simplex virus types 1 and 2 (hsv-1 and hsv-2) was detected using dna from mixedly infected cells. because hsv-1 and hsv-2 share a 50% base sequence homology along the genome but have markedly different dna restriction enzyme cleavage patterns, recombination events can be detected and quantified by analysis of restriction endonuclease digests for the presence of novel dna fragments. we have used this technique to quantify the degree of interference by hsv-2 ... | 1984 | 6323508 |
| [evaluation of 80 virologically-confirmed cases of ocular herpes. study of the correlation between the type of virus and the epidemiologic characteristics of the disease]. | 80 strains were isolated from patients with herpetic ocular infection during the period may 1979 to may 1981: 17 patients with herpetic blepharitis, 40 patients with superficial keratitis and 23 with deep stromal keratitis or kerato-uveitis. among 63 patients treated with antiviral agents, clinical resistance to the drug was observed in 17 cases. the strains were typed as hsv 1.1, 1.2 or 2.2 by seroneutralization and thermosensitivity in cellular cultures. no relationship between the viral types ... | 1983 | 6323567 |
| immunotoxic effects of diethylstilbestrol on host resistance: comparison with cyclophosphamide. | to evaluate the usefulness of host resistance assays for measurement of immunotoxicologic effects of chemicals, the immunosuppressive effects of exposure to diethylstilbestrol (des) were compared with the effects of treatment with the known immunosuppressive drug cyclophosphamide (cps). a panel of six host resistance models was evaluated, including infection with the bacterium listeria monocytogenes, herpes simplex virus type 2 (hsv-2), and encephalomyocarditis virus (emc), the yeast cryptococcu ... | 1984 | 6323603 |
| characterization of the 92,000-dalton glycoprotein induced by herpes simplex virus type 2. | evidence is presented showing that the 92,000-dalton glycoprotein (g92k) induced by herpes simplex virus (hsv) type 2 has properties distinct from those assigned to any other hsv glycoprotein. first, the carbohydrate composition and extent of sulfation differ from those of glycoproteins d and e. second, two clonally unrelated monoclonal antibodies, ap1 and lp5, shown in this paper to specifically immunoprecipitate g92k, do not react with any of the known processed forms of glycoproteins b, c, d, ... | 1984 | 6323754 |
| resistance of herpes simplex virus to 9-[[2-hydroxy-1-(hydroxymethyl)ethoxy]methyl]guanine: physical mapping of drug synergism within the viral dna polymerase locus. | a herpes simplex virus type 2 (hsv-2) mutant ts6 (strain hg52) induces a heat-labile viral dna polymerase at the nonpermissive temperature and is markedly resistant to 9-[[2-hydroxy-1-(hydroxymethyl)ethoxy]methyl]-guanine [2'-nor-2'-deoxyguanosine; 2'ndg]. this antiviral drug requires hsv thymidine kinase for phosphorylation to an active inhibitor (2'ndg-triphosphate), and thymidine kinase-deficient mutants of hsv exhibit varying degrees of resistance to 2'ndg, with the hsv type 1 (hsv-1) b2006 ... | 1984 | 6324203 |
| herpes simplex virus infection causes the accumulation of a heat-shock protein. | a monoclonal antibody, produced from mice immunized with a herpes simplex virus (hsv)-infected cell extract, reacts with a molecule which is present in uninfected cells and which accumulates in large amounts during hsv 2 infection. in uninfected cells this molecule is growth regulated, in that exponentially growing cells have intense nuclear immunofluorescence, whereas confluent quiescent cells have little. it has a mol. wt. of 57 000 (p57) in exponential cells, and one of 61 000 (p61) in quiesc ... | 1984 | 6325164 |
| synthesis of some phosphonates with antiherpetic activity. | several keto phosphonates, phosphonoacetates , and dialkyl phosphonates containing (aryloxy)aryl groups were synthesized and evaluated for antiherpteic activity. two of the most active compounds, 12 and 16, were evaluated topically in the mouse vaginal model against herpes simplex virus (hsv) type 2. compound 16 exhibited an increased survival rate, as well as increased survival time. evaluation of 16 in the guinea pig skin test against hsv-2 produced a reduction in virus titer, as well as in me ... | 1984 | 6325695 |
| "recurrent herpes zoster": an unproved entity? | physicians sometimes misdiagnose recurrent zosteriform herpes simplex virus (hsv) skin infections as "zoster" or "recurrent zoster." misdiagnosis can lead to inappropriate therapy with potentially harmful consequences, particularly in patients with ophthalmitis or immunosuppression, in which early institution of the correct antiviral therapy may be crucial. we report three patients who were originally misdiagnosed to have recurrent herpes zoster skin infections before we cultured hsv from their ... | 1984 | 6327783 |
| secretory iga antibody in cervicovaginal secretions from women with genital infection due to herpes simplex virus. | sequential samples of cervicovaginal secretions from women with untreated first and recurrent episodes of genital infection due to herpes simplex virus type 2 (hsv-2) were assayed for iga antibodies to hsv-2 by using fluorescent antibodies to human secretory piece (siga) and human iga. among women with first-episode genital herpes, siga antibody to hsv-2 was detected in 20 of 31 women from whom hsv was isolated from the cervix, compared with four of 13 women from whom it was not (p less than .05 ... | 1984 | 6327834 |
| immunogenicity of herpes simplex virus glycoproteins gc and gb and their role in protective immunity. | the relative antigenicity of the individual herpes simplex virus type 1 (kos) glycoproteins gc and gb was analyzed in balb/c mice by using kos mutants altered in their ability to present these antigens on cell surface membranes during infection. the mutants employed were as follows: syn ld70 , a non-temperature-sensitive mutant defective in the synthesis of cell surface membrane gc; tsf13 , a temperature-sensitive mutant defective in the processing of the precursor form of gb to the mature cell ... | 1984 | 6328010 |
| physical mapping of the herpes simplex virus type 2 nuc- lesion affecting alkaline exonuclease activity by using herpes simplex virus type 1 deletion clones. | the nuc- lesion affecting alkaline exonuclease activity in the herpes simplex virus type 2 (hsv-2) mutant ts1348 had previously been mapped to the ecori-d restriction enzyme fragment of hsv-1. eight clones with deletions representing most of hsv-1 ecori fragment d were selected with lambda gtwes hybrids. these clones were tested for their ability to rescue the alkaline exonuclease activity of hsv-2 nuc- ts1348 virus. the sequences colinear with the hsv-2 nuc- lesion were found to map between 0.1 ... | 1984 | 6328043 |
| glycoprotein c of herpes simplex virus 1 acts as a receptor for the c3b complement component on infected cells. | receptors for the fc portion of immunoglobulins or for the third component of complement (c3) are present on a variety of circulating and fixed tissue cells including granulocytes, monocytes, lymphocytes and glomerular epithelial cells. cells which lack fc receptors may express them after infection by herpes simplex virus (hsv)-1, hsv-2, cytomegalovirus or varicella zoster virus. we recently reported that infection by hsv-1 induces both fc and c3 receptors on human endothelial cells. glycoprotei ... | 1984 | 6328323 |
| characterization of an aphidicolin-resistant mutant of herpes simplex virus type 2 which induces an altered viral dna polymerase. | the replication of wild-type herpes simplex virus type 2 (hsv-2) was very sensitive to aphidicolin, a specific inhibitor of eukaryotic alpha-type dna polymerases; viral dna synthesis was strongly inhibited by 1 microgram/ml of aphidicolin, but the synthesis of early viral polypeptides was not affected. using aphidicolin as the selective agent, aphidicolin-resistant ( aphr ) viruses were isolated from hsv-2 strain 186. all of these plaque isolates induced altered viral dna polymerases which were ... | 1984 | 6328755 |
| phosphorylation of four acyclic guanosine analogs by herpes simplex virus type 2 thymidine kinase. | four acyclic guanosine analogs, the (r) and (s) enantiomers of 9-(3,4-dihydroxybutyl)guanine, 9-(4-hydroxybutyl)guanine, and acyclovir were compared in enzyme kinetic experiments, using purified herpes simplex virus type 2 thymidine kinase. all four analogs showed competitive patterns of inhibition in the phosphorylation of thymidine by the viral thymidine kinase, but different affinities and relative rates of phosphorylation were observed. | 1984 | 6329085 |
| direction of synthesis of the message for a 35 000 polypeptide of herpes simplex virus type 2. | a restriction endonuclease map of the coding sequences for the transformation-related 35 000 polypeptide of herpes simplex virus type 2 is reported, using 11 enzymes that cut dna infrequently. hybrid-arrested translation with small dna fragments was used to locate the 5' terminus of these coding sequences. a novel procedure involving translation of the 35 000 mrna selected with cloned viral dna that had been digested with exonuclease was employed to confirm that this message is transcribed from ... | 1984 | 6329490 |
| herpes virus antigens and antibodies in kidney biopsies and sera of iga glomerulonephritic patients. | antibody titers against 4 viruses of the herpes group have been studied in the sera of 54 patients with iga glomerulonephritis (gn). the incidence of antibodies to herpes simplex virus type-1 (hsv-1), hsv-2, cytomegalovirus (cmv), epstein-barr virus nuclear antigen (ebna), and that of igg antibodies to ebv virus capsid antigen (vca) were similar in patients and in controls. however, elevated antibody titers (greater than or equal to 64) to hsv and cmv occurred more frequently in patients with ig ... | 1984 | 6329570 |
| expression of a herpes simplex virus glycoprotein in two clonal lines of hamster cells transformed by herpes simplex virus type 2. | expression of herpes simplex virus type 2 (hsv-2) glycoproteins on the cell surface of two clones of a hamster cell line transformed by hsv-2 was examined by immunofluorescence tests with hamster antisera prepared against three size-class glycoprotein fractions obtained from hamster embryo fibroblast cells infected with hsv-2. enhanced expression of one of the three size-class glycoprotein fractions (molecular weight, 82,000-94,000) was found in one clone (155-4-213) after replating of the cells ... | 1984 | 6329882 |
| structural organization of human herpesvirus dna molecules. | the herpesviruses are among the largest and most complex of all dna viruses, and their genomes display an astonishing diversity in size, structure, and organization. in 1974, the features of large inverted repeats and structural isomerization were first discovered, and these proved to be characteristic properties of many herpesvirus genomes. since then, research using the powerful techniques of modern molecular biology has revealed a great deal of comparative structural information about the arr ... | 1984 | 6330219 |
| genital herpes simplex infections: effect of asymptomatic shedding and latency on management of infections in pregnant women and neonates. | asymptomatic shedding of herpes simplex virus (hsv) at delivery occurred in 2.4% of women with a past history of recurrent genital infections; using current methods, this could not be predicted in advance. in addition, only 22% of the mothers of infected infants had an elicitable history of recurrent genital infections. passively derived neutralizing antibody titers of 1:106 to hsv-1 and 1:67 to hsv-2 were found in 22 exposed infants who remained asymptomatic as compared with 1:8 and 1:8, respec ... | 1984 | 6330222 |
| herpes simplex virus type 2 establishes latency in the mouse footpad and in the sensory ganglia. | three mouse strains as well as wt and 7 ts mutants of herpes simplex virus (hsv) type 2 (strain hg52) have been used to investigate latency. the mice were inoculated in the right rear footpad. virus reactivation following explanation and culture of the dorsal root ganglia and the footpad was scored. the results show that: hsv-2 can be maintained in the mouse footpad in a state indistinguishable from latency; virus gene functions necessary for latency can be identified by the use of ts mutants; a ... | 1984 | 6330225 |
| hsv, cmv, and hpv in human neoplasia. | we are studying the role of sexually transmitted viruses in the development of human tumors. the persistence of herpes simplex virus, cytomegalovirus, and human papillomavirus nucleic acid sequences has been examined using cloned viral dna sequences as probes. the relationship of the viruses to various stages in the progression of neoplasia is examined, with particular reference to the role of viral and/or cellular genes in the initiation, promotion, and maintenance of the neoplastic phenotype. ... | 1984 | 6330227 |
| determination of herpes simplex virus type-specific antibodies by solid-phase ria on helix pomatia lectin-purified antigens. | herpes simplex virus type 1 (hsv-1) and type 2 (hsv-2) antibodies in humans and animals were determined by a micro-solid-phase radioimmunoassay with helix pomatia lectin/sepharose 4b-purified antigens from hsv-1- and hsv-2-infected cells. a low but constant heterotypic reactivity was found with hsv-1 antigen, whereas hsv-2 antigen was type specific, as evidenced by (1) its reactivity with sera from hsv-2- but not with those from hsv-1-immunized animals, (2) its reactivity with monoclonal antibod ... | 1984 | 6330240 |

| evaluation of the effectiveness of 2h-1,3-oxazine-2,6(3h)-dione (oxauracil) in the treatment of herpes simplex virus (hsv)-induced acute encephalitis in mice. | treatment of suckling mice with the pyrimidine analogue 2h-1,3-oxazine-2,6(3h)-dione (oxauracil) proved successful in reducing mortality associated with hsv-2-induced encephalitis. oxauracil did not decrease mortality associated with hsv-1 infection; however, there was an increased survival time and a decrease in the amount of infectious virus recovered from the brains of hsv-1-infected animals. | 1984 | 6330291 |
| homology between two ebv early genes and hsv ribonucleotide reductase and 38k genes. | computer-matching of amino acid sequences predicted from the complete ebv dna sequence against the known hsv gene sequences has revealed significant homology between two ebv reading frames and the hsv1 and hsv2 140k and 38k proteins which are associated with ribonucleotide reductase activity. the two genes are arranged tandemly as in hsv though it appears that, unlike hsv, the two mrnas are not 3' co-terminal. we have mapped two promoters predicted from the dna sequence for these genes and shown ... | 1984 | 6330697 |
| nucleotide sequence of the marmoset herpesvirus thymidine kinase gene and predicted amino acid sequence of thymidine kinase polypeptide. | the nucleotide sequence of a 2549-bp dna fragment containing the entire coding region of the marmoset herpesvirus (marhv) thymidine kinase gene (tk) and the flanking sequences was determined by the dideoxynucleotide chain termination method. the marhv thymidine kinase polypeptide predicted from the nucleotide sequence contained 376 amino acids and had a molecular weight of 41,281. the sequencing data also reveal that the coding portion of another marhv gene probably begins only 292 nucleotides d ... | 1984 | 6330976 |
| enhanced efficacy of the acyclic nucleoside 9-(1,3-dihydroxy-2-propoxymethyl)guanine in combination with alpha-interferon against herpes simplex virus type 2 in mice. | the acyclic nucleoside dhpg [9-(1,3-dihydroxy-2-propoxymethyl)guanine] and recombinant human alpha-interferon of clones a/d potentiate each other's antiviral activity against a systemic infection with herpes simplex virus type 2. the effective dose at which 50% of the mice survived was lowered approximately 10-fold for dhpg when it was given in combination with a marginally effective dose of alpha-interferon and greater than 10-fold for alpha-interferon when it was given in combination with a no ... | 1984 | 6335382 |
| rapid diagnosis of varicella-zoster virus infection by detection of viral deoxythymidine kinase in serum and vesicle fluid. | a sensitive enzyme assay utilizing [125i]iododeoxyuridine as the substrate and ctp as the phosphate donor in combination with isozyme-specific antisera was used for direct detection and typing of herpesvirus deoxythymidine kinase (dtk) in clinical specimens. an investigation of 16 coded vesicle fluid specimens, taken in connection with varicella-zoster virus (vzv) and herpes simplex virus infections, revealed viral dtk activity in 14 samples. all positive samples except one were taken within 5 d ... | 1983 | 6339548 |
| current status and prospects for oral acyclovir treatment of first episode and recurrent genital herpes simplex virus. | herpes simplex genitalis is an increasingly common primary or recurrent hsv infection. acyclovir (acv) has been found to diminish virus shedding and clinical symptoms in patients with first episode genital hsv when given topically or intravenously. as most patients with first episode disease do not require hospitalization and recurrent disease is usually less severe than the primary infection, out-patient treatment forms the basis of practical management. acyclovir is absorbed orally with plasma ... | 1983 | 6355052 |
| lysis of herpesvirus-infected cells by macrophages activated with free or liposome-encapsulated lymphokine produced by a murine t cell hybridoma. | thioglycolate-induced mouse peritoneal macrophages were activated in vitro by the lymphokine designated macrophage-activating factor (maf) produced by a murine t cell hybridoma to lyse herpes simplex virus type 2 (hsv-2)-infected murine target cells. comparison of uninfected balb/c 10e2 cells with hsv-2-infected 10e2 cells showed that macrophages activated with maf selectively destroyed hsv-2-infected cells and left uninfected cells unharmed, as measured by an 18-h 51cr-release assay. in contras ... | 1983 | 6358037 |
| polypeptide specificity of the early antibody response following primary and recurrent genital herpes simplex virus type 2 infections. | relative igg titres to specific viral proteins in acute and convalescent sera from patients with primary and recurrent genital herpes simplex virus type 2 (hsv-2) infections were determined using an immunoblot assay. patients with recurrent genital infections generally had high titres of antibody reactive with two of the three major viral glycoproteins (gd and gg) as well as with several viral capsid proteins in both acute and convalescent sera. in contrast, patients experiencing primary genital ... | 1984 | 6387042 |
| epidemiological aspects of cervical cancer in tropical africa. | cervical cancer is one of the most common malignant tumours in tropical africa accounting, for example, for nearly one-quarter of female cancer cases overall in uganda. the disease is likely to be under-reported and available incidence rates are probably gross underestimates. spread is through sexual contacts. both female and male promiscuity and a low standard of sexual hygiene lead to a high incidence within a given community. a number of investigations show that the risk of cervical cancer va ... | 1984 | 6399280 |
| carcinoma of the cervix: can a viral etiology be confirmed? | the etiological role of viruses in various animal cancers is no longer in doubt; a similar role in human cancers is, however, yet to be confirmed. indeed, until recently, virus infections were considered to be responsible for only a small proportion of the clinical states encountered in humans and the view that viruses may be etiological agents for human malignant tumours was not seriously entertained. with the introduction of more advanced techniques in immunovirology, the role of viruses in cl ... | 1984 | 6399281 |
| preferential inhibition of 5-trifluoromethyl-2'-deoxyuridine phosphorylation by 5'-amino-5'-deoxythymidine in uninfected versus herpes simplex virus-infected cells. | the cytotoxic effects of 5-trifluoromethyl-2'-deoxyuridine (cf3durd) were effectively antagonized by 5'-amino-5'-deoxythymidine (5'-adthd). the antiproliferative actions of cf3durd were reduced in a dose-dependent manner by 5'-adthd in both hela and vero cells. in addition, the ability of cf3durd to kill hela cells (95% at 1 microm and 99% at 3 microm), as measured by cloning efficiency, was ablated entirely by 5'-adthd (300 microm). in contrast, the inhibition of herpes simplex virus type 2 (hs ... | 1983 | 6408395 |
| ultrastructural localization of gold in macrophages and mast cells exposed to aurothioglucose. | the ultrastructural localization of gold in resting, stimulated, and activated mouse peritoneal cells exposed in vivo and in vitro to aurothioglucose was examined by a photochemical technique. activated macrophages from herpes simplex virus type 2 infected mice showed the heaviest accumulation of gold, located in phagolysosomes. gold was also visualized in granules of mast cells and in nuclei of disintegrated cells. no gold was found in polymorphonuclear leucocytes and in lymphocytes. the mechan ... | 1984 | 6420183 |
| human monocytes activated by immunomodulators in liposomes lyse herpesvirus-infected but not normal cells. | highly purified peripheral blood monocytes from normal human donors were activated in vitro by incubation with liposomes containing immunomodulators such as recombinant human gamma interferon, human lymphokines, or muramyl dipeptide. the ability of liposomes containing immunomodulators to activate monocytes to a cytotoxic state capable of discriminating between virus-infected and uninfected cells was shown by activated monocytes recognizing and destroying herpes simplex virus type 2-infected cel ... | 1984 | 6426057 |
| topical treatment of cutaneous herpes simplex virus infection in hairless mice with (e)-5-(2-bromovinyl)-2'-deoxyuridine and related compounds. | (e)-5-(2-bromovinyl)-2'-deoxyuridine (bromovinyldeoxyuridine) was found to suppress the development of herpetic skin lesions and the paralysis and mortality associated therewith in hairless mice inoculated intracutaneously with herpes simplex virus type 1. this protective effect was achieved with bromovinyldeoxyuridine applied topically at 1, 3, or 10% in either dimethylsulfoxide (dmso), beeler base, tween-glycerol-water, 5% azone (1-dodecylazacycloheptan-2-one) in water, or 5% azone in dmso. th ... | 1984 | 6486759 |
| broad-spectrum synergistic antiviral activity of selenazofurin and ribavirin. | the antiviral effects of selenazofurin (2-beta-d-ribofuranosylselenazole-4-carboxamide, selenazole), ribavirin (1-beta-d-ribofuranosyl-1,2,4-triazole-3-carboxamide), and 3-deazaguanosine (6-amino-1-beta-d-ribofuranosylimidazo-[4.5-c]pyridin-4(5h)-one) were investigated separately and in various combinations in an in vitro study. the combination interactions were evaluated at seven drug concentrations, graphically (isobolograms) or by using fractional inhibitory concentration indices against mump ... | 1984 | 6517540 |
| recurrences after first episodes of genital herpes in patients treated with topical acyclovir cream. | the effect of topical acyclovir treatment of first episode genital herpes on the time to first recurrence in a group of 42 patients receiving either acyclovir or placebo was investigated. topical acyclovir treatment had no effect on time to first recurrence in patients with either first episode hsv-1 or hsv-2 infections. there was no significant difference in the time to first recurrence in patients with either true primary or initial genital infections. however, the time to first recurrence in ... | 1984 | 6517563 |
