| dna polymerase in pseudorabies virus infected cells. | the dna polymerase activity in bhk 21/c13 cells infected with pseudorabies virus is inhibited by incubation with antiserum to pseudorabies but not by incubation with pre-immune serum or by antiserum to herpes simplex virus type 1 (hsv-1) or herpes simplex virus type 2 (hsv-2). it also differs from the cell enzyme and the enzymes in hsv-1 or hsv-2 infected cells in its requirement for kcl in the in vitro assay. it seems likely, therefore, that pseudorabies virus specifies its own dna polymerase. | 1976 | 173798 |
| a study of the immuno-suppressive activity of herpes simplex virus type 2 and the tumor enhancing potential of the virus on yoshida sarcoma. | the relative delays of yoshida sarcoma (ys) tumor induction were used as indicator for the immunosuppressive potential caused by the subcutaneous infection of sprague-dawley rats with approximately 10(7) tcd50 hsv-2. the tumor formation is clearly accelerated and the number of tumors is increased as compared to sham injected rats. the impairment of immunity is at its maximum when the virus and the ys cells are applied simultaneously, whereas virus given after the tumor is of no consequence. the ... | 1975 | 174048 |
| herpes simplex virus type 2 and acute aseptic meningitis. clinical features of cases with isolation of herpes simplex virus from cerebrospinal fluids. | herpes simplex virus (hsv) was recovered from the cerebrospinal fluids (csf) of 10 patients with acute aseptic meningitis. hsv type 1 was isolated from the csf of a 6-month-old boy. the other 9 hsv isolates from csf were from adults in the age-group 15 to 29 years; 7 of these isolates were available for typing and were identified as hsv type 2. in a further 9 patients with acute aseptic meningitis and belonging to the same age-group a hsv infection was suggested by a significant titre rise in co ... | 1975 | 174191 |
| prospective double-blind evaluation of topical adenine arabinoside in male herpes progenitalis. | thirty-four virologically proven episodes of herpes progenitalis in 32 men were treated in a prospective double-blind study with either adenine arabinoside ointment or an identical-appearing placebo for 7 days. clinical evaluation and quantitative virological studies were done on days 1, 3, and 8. there was a highly significant correlation between clinical response and quantitative virology. there was no difference in clinical or virological response between drug and control groups. primary atta ... | 1975 | 174489 |
| [seroepidemiological studies related to the association of genital herpes to cervical cancer (author's transl)]. | blood sera of 290 patients were examined for the presence of antibodies against herpes simplex virus type 1 and type 2 (hsv-1 and hsv-2): 1. lues - seronegative individuals, 2. patients with specific lues antibodies, and 3. patients with so-called carcinoma in situ and invasive carcinoma of the uterine cervix. the group of syphilis-seropositive individuals served as control for the group with cervical lesions, because in both groups certain socioepidemiologic factors (promiscuity, early sexual i ... | 1975 | 174969 |
| deoxycytidine kinase from rabbit kidney cells infected with herpes simplex virus type 1 or 2. | when rabbit kidney cells were infected with herpes simplex virus type 1 (strain seibert) or herpes simplex virus type 2 (strain 316d), deoxycytidine kinase (cdr kinase) activity, assayed at 38 degrees, increased 5- to 15-fold relative to controls. the cdr kinase activity induced by type 2 virus was more thermolabile than the enzyme activity induced by type 1 virus. when cdr kinase activity was assayed at various temperatures between 0.5 and 38 degrees, maximum activity for type 1 enzyme was obta ... | 1976 | 175378 |
| human ecto- and endocervical epithelial cells as targets for herpes simplex type two infection in vitro. | an in vitro method was used to compare the herpes simplex virus type 2 (hsv2) susceptibility of human ecto- and endocervical epithelial cells as well as the induced cellular alterations. hsv2 caused a productive infection and morphological alterations both in ecto- and endocervical epithelial cells, but the cytopathogenicity, virus production and development of hsv2 antigens showed a greater sensitivity of ectocervical cells to hsv2 infection. the cytopathogenicity and production of infectious v ... | 1976 | 175640 |
| editorial: herpesvirus and cancer of uterine cervix. | frequent coitus with several partners or at a very young age carries the greatest risk of cancer of the uterine cervix. lowest risk is among celibate women and those who live in communities where marriage is stable and where premarital and extramarital coitus is infrequent. all evidence points to the venereal hypothesis of cervical cancer. herpes simplex virus type 2 (hsv-2) has been implicated. immunological defenses, oxygen tension, ph, and hormonal changes in the cervical tissues may also ... | 1976 | 175880 |
| a search for herpes simplex virus type 2 markers in cervical carcinoma. | carcinoma of the uterine cervix is now clearly recognized as the second most common malignant disease of women in the united states. epidemiological studies provided the first suggestive evidence that an infectious, venereally transmitted agent was involved in this disease in either a causal or a casual fashion. later cytohistopathological, virological, and seroepidemiological studies confirmed this observation and identified the suspect agent as herpes simplex virus type 2. recently, several la ... | 1976 | 175943 |
| herpesvirus type 2-related antigens and their relevance to humoral and cell-mediated immunity in patients with cervical cancer. | the central theme of this communication is the interaction of herpes simplex virus type 2 with its host. in addition to the productive infection, we are confronted by latency and, as suggested by recent studies, by cancer. the possible mechanisms of latency and the role it may play as a precursor of carcinogenesis are discussed. if virus is to coexist with its host, a defined level of molecular interaction between host and viral gene products must exist. the association of ag-4 with active tumor ... | 1976 | 175945 |
| anal infections caused by herpes simplex virus. | herpes simplex infections of the perianal skin and anal canal are not uncommon, as evidenced by the present series of 16 cases, but have rarely been reported in the literature of the past. they are caused by the hsv-2 virus, which is also associated with genital lesions. there is abundant evidence that anogenital herpes is a venereal disease. anal herpes is most commonly transmitted by anal intercourse. when the infection is present inside the anal canal, especially in a primary attack, the pain ... | 1976 | 176017 |
| effect of cross-immunization on monotypic antibody responses to herpes simplex virus types 1 and 2. | new zealand white rabbits were immunized subcutaneously with partially purified uv-inactivated preparations of herpes simplex virus (hsv-1 or hsv-2) in complete freund's adjuvant. after the initial immunizations, designated groups of animals received additional amounts of either hsv-1 or hsv-2 at 35-day intervals. sera were absorbed with lysates of cells infected with heterotypic virus and the residual monotypic antibodies were detected by 51cr-release assay using hsv-infected target cells. a po ... | 1976 | 176275 |
| igm antibody to a tumor-associated antigen (ag-4) induced by herpes simplex virus type 2: its use in location of the antigen in infected cells. | rate-zonal centrifugation was used to separate 7s and 19s lg's from sera of patients with cervical cancer and of controls. the lg's were assayed for their ability to recognize ag-4, a tumor-associated antigen, and herpes simplex virus 2 (hsv-2) by various serologic assays including neutralization, immunofluorescence, and complement fixation. these studies indicated that antibody to ag-4 is a macroglobulin; antibody-fixing complement with hsv-2 is a 7s lg. the results of various serologic assays ... | 1976 | 176392 |
| quantitation of the viral dna present in cells transformed by uv-irradiated herpes simplex virus. | two cell lines biochemically transformed by uv-irradiated herpes simplex virus (hsv) each contain virus dna. a comparison of the kinetics of reassociation of 3h-labeled hsv dna in the presence and absence of either clone 139 (hsv-1 transformed) or clone 207 (hsv-2 transformed) dna showed that the presence of transformed cell dna increased the rate of reassociation of approximately 10% of the viral genome while having no effect on the remaining 90%. the cot1/2 of this reaction was approximately 1 ... | 1976 | 176444 |
| deoxyribonucleoside triphosphate pools in synchronized human cells infected with herpes simplex virus types 1 and 2. | deoxyribonucleoside triphosphate pools in uninfected and herpes simplex virus type 1 (hsv-1)- and hsv-2-infected kb cells were analyzed to determine whether ribonucleotide reductase functions in vivo in the presence and absence of thymidine (tdr). previously we showed that hsv-2 replication was inhibited in kb cells blocked in their capacity to synthesize dna by tdr. hsv-1 replication was not inhibited under these conditions. both hsv-1 and hsv-2 induced an altered ribonucleotide reductase resis ... | 1976 | 176471 |
| host range temperature-sensitive mutants of herpes simplex virus type 2. | two small-plaque mutants of herpes simplex virus type 2 (hsv-2) (strain 333), whose growth at 39 c was blocked in certain cell types (cell-dependent temperature sensitivity), were compared compared with parental virus in a number of biological assays. one mutant (no. 69) was found to produce a large number of morphologically normal, but noninfectious, particles; under nonpermissive conditions, these mutant particles were able to interfere with the replication of wild-type hsv-2. the other mutant ... | 1976 | 176473 |
| electron microscope observations on tubular structures in cells infected with herpes simplex virus type 2. | the fine structure of filamentous structures and lattice-like structures found in herpes simplex virus type 2-infected cells was studied. by specimen tilting experiments, it was demonstrated that the lattice-like structures were the cross-sectional views of the tubular structures and the filamentous structures were the longitudinal sections. the observation in negatively stained preparations of isolated tubular structures revealed that the structure was constructed by regular array of ring shape ... | 1976 | 176968 |

| mutants of herpes simplex virus types 1 and 2 that are resistant to phosphonoacetic acid induce altered dna polymerase activities in infected cells. | three mutants of herpes simplex virus (hsv) have been isolated which form plaques in the presence of 100 mug/ml phosphonoacetic acid (ppa). all three mutants (3 from hsv-1 strain 17 syn+, 14 from hsv-1 strain 17 syn, and 19 from hsv-2) induce viral dna synthesis and viral dna polymerase activity, and these are much less sensitive to ppa than the wild-type virus. the results support the hypothesis that ppa interacts directly with the viral dna polymerase protein, at least part of which is virus c ... | 1976 | 177727 |
| herpesvirus proteins: dna polymerase and pyrimidine deoxynucleoside kinase activities in temperature-sensitive mutants of herpes simplex virus type 2. | eleven temperature-sensitive mutants of herpes simplex virus type 2 strain hg52 were examined for ability to induce dna polymerase activity in bhk 21/c13 cells. all mutants induced dna polymerase at a permissive temperature, (31 degrees c) and all dna-positive mutants at a non-permissive temperature (38 degrees c). three dna-negative mutants induced no dna polymerase (ts 6, ts 9) or very little dna polymerase (ts 11), at a non-permissive temperature, while ts 1, also dna negative, induced a litt ... | 1976 | 177730 |
| effects of immunostimulants on resistance of newborn mice to herpes simplex type 2 infection. | since age-dependent diminished macrophage function has been related to the increased susceptibility of newborn mice to herpes simplex virus (hsv) infection, the effect of several agents which might activate macrophages or other cells involved in immunity was investigated. bcg, typhoid vaccine, brucella vaccine, levamisole, or staphage lysate were administered to newborn mice prior to challenge with hsv-2. of these agents, only bcg, administered ip or id 6 days prior to challenge, was found to in ... | 1976 | 177992 |
| cross-reacting herpes simplex virus antigens in hamster and mouse cells transformed by ultraviolet light-inactivated herpes simplex virus type 2. | murine and hamster cell lines, each transformed with a different strain of herpes simplex virus (hsv), were examined for cross-reacting antigens by in vitro and in vivo assays. a comparative study by the indirect immunofluorescence technique detected common cross-reacting viral antigens. cytoplasmic fluorescence patterns were observed in the 333-8-9 hamster line, the h238 murine line, and the h238 clonal lines; these patterns were identical to the fluorescence pattern of hsv -2-infected controls ... | 1976 | 178596 |
| quantitative cytophotometry evaluated as a method for analyses of herpes simplex viral deoxyribonucleic acid synthesis. | feulgen deoxyribonucleic acid (f-dna) microspectrophotometry was evaluated as a potential tool for quantification of herpes simplex virus type 1 (hsv-1) and 2(hsv-2) dna synthesis in single cells. since hsv dna synthesis has been extensively studied using incorporation of radioactive precursors into viral and cellular dna, microspectrophotometric measures were correlated with biochemical data obtained using tritium-labeled thymidine ([3h]tdr). it was established that: (i) viral-induced increaae ... | 1976 | 178608 |
| electron microscope studies of temperature-sensitive mutants of herpes simplex virus type 2. | nine temperature-sensitive mutants of herpes simplex virus type 2 representing eight complementation groups were assigned to two classes as a consequence of the virion forms and virus-specific cellular alterations observed in thin sections of mutant-infected human embryonic lung cells grown at the nonpermissive temperature. mutants in class a, one dna- and one dna +, failed to synthesize detectable virus particles. mutants in class b, 4dna- and 3dna+, produced moderate to large numbers of empty ... | 1976 | 178905 |

| herpes simplex virus dna in transformed cells: sequence complexity in five hamster cell lines and one derived hamster tumor. | analyses of the hybridization kinetics of labeled herpes simplex virus 2 (hsv-2) dna with dna from five hamster cell lines transformed by uv light-irradiated hsv-2 revealed the following. (i) viral dna sequences were detected in all five cell lines tested. (ii) none of the cell lines contained the full complement of hsv-2 dna. (iii) the amount of viral dna present in the cells varied in different transformed cell lines and ranged from 8 to 32% of the hsv-2 dna genome in 1 to 3 copies/cell. (iv) ... | 1976 | 178927 |

| viruses and cancer of the lower genital tract. | the importance of viruses as oncogenic agents in animals is well established. recent work suggests that viruses may also be etiologically related to some human cancers. herpes simplex virus type 2 (hsv-2) and the genital wart virus are prime suspects in carcinomas involving the female lower genital tract. in particular, a close association has been found between hsv-2 infection and cervical neoplasia in cytohistopathologic and seroepidemiologic studies. preliminary results of prospective studies ... | 1976 | 179694 |
| the detection of virus dna sequences in a herpes type 2 transformed hamster cell line (333-8-9). | herpes simplex virus type 2 dna labelled in vitro with 125i has been used as a probe to search for virus dna sequences in the 333-8-9 line of transformed primary hamster cells and in clines derived from the line. virus dna sequences were present when the cells were examined initially but these sequences were lost on subsequent handling. no virus sequences were detected in clones derived from the line. it is suggested that the presence of virus dna is an unstable characteristic of the cell line a ... | 1976 | 179957 |
| clonal derivatives of a herpes type 2 transformed hamster cell line (333-8-9): cytogenetic analysis, tumorigenicity and virus sequence detection. | the characteristics of the syrian hamster cell line (333-8-9), putatively transformed by herpes virus type 2 (hsv-2), strain 333, have been examined. the line has been cloned and the clones characterized cytogenetically and morphologically. the original line and the clones have been assayed for tumorigenicity and for the presence of herpes-virus-specific nucleic acid sequences using in situ hybridization with 125i hsv-2 dna. the line 333-8-9 is hyperdiploid with a mode of 49 chromosomes and cont ... | 1976 | 179958 |
| comparison of herpes simplex virus isolates using a quantitative selection assay for transformation. | transformation potential of herpes simplex virus types 1 and 2 (hsv-1 and hsv-2) was quantitatively compared in a system selecting for biochemical transformants. the highest frequency of transformation was obtained with hsv-2 strain 333. the transformation rates for two strains of hsv-1 were lower and distinctly different from hsv-2 and from each other. the dose of inactivating ultraviolet light received by the virus and the multiplicity of infection proved to be critical components of the proce ... | 1975 | 179966 |
| immunopotentiation and antiviral chemotherapy in a suckling rat model of herpesvirus encephalitis. | encephalitis was induced in 10-day-old wistar rats by intraperitoneal injection of approximately 100 50% tissue culture infective doses of herpes simplex virus type 2. treatment regimens included immunopotentiation with levamisole and combined therapy with levamisole and an antiviral agent, adenine arabinoside. rats treated with levamisole alone had significantly higher rates of survival than placebo-treated controls 14 days after injection of virus. combination therapy with levamisole and adeni ... | 1976 | 180203 |
| histocompatibility types and viral antibodies. | serum neutralizing (nt) antibodies to herpes simplex virus type 1 (hsv-1) and type 2 (hsv-2), and histocompatibility (hl-a) types, were determined in multiple sclerosis (ms) patients and in control subjects. titers of nt antibodies to hsv-1 and to hsv-2 were increased among subjects bearing hl-a3 or hl-a7 or both, whether they suffered from ms or not. the increases were statistically significant in the ms group. the ms and control groups did not differ significantly in levels of hsv-1 or hsv-2 n ... | 1976 | 180933 |
| herpes simplex virus types 1 and 2: therapeutic response to antiviral drugs. | in vitro studies have demonstrated a relative resistance of herpes simplex virus type 2 to antiviral therapy when compared with herpes simplex virus type 1. the in vivo studies, however, show an excellent therapeutic response to both antiviral drugs in experimentally induced viral keratoconjunctivitis. | 1976 | 180942 |
| temperature-sensitive mutants of herpes simplex virus type 2: a provisional linkage map based on recombination analysis. | thirteen ts mutants of type 2 herpes simplex virus were backcrossed to a syncytial but not temperature-sensitive mutant of wild-type virus. this was an attempt to introduce a third marker, syncytial plaque morphology or syn, into at least some of the ts mutants. three ts mutants carrying the syn marker were obtained but only one, ts 9, was satisfactory for genetic experiments. three-factor crosses were carried out between ts 9 syn and the mutants which determined the order of eleven ts mutations ... | 1976 | 181531 |
