| susceptibility of common marmosets (callithrix jacchus) to oncogenic and attenuated strains of herpesvirus saimiri. | adult common marmosets, inoculated with either of 2 oncogenic herpesvirus saimiri (hvs) strains, developed fatal lymphoproliferative disease within 23-25 days post inoculation (pi). the disease was identical to hvs-induced lymphoma in cotton-topped and white-lipped marmosets. common marmosets inoculated with an attenuated hvs strain developed persistent infection; virus has been recovered from cocultivated lymphocytes of these animals for more than 384 days pi. | 1977 | 198565 |
| establishment of a cell line with associated epstein-barr-like virus from a leukemic orangutan. | an epstein-barr virus like herpesvirus has been isolated from a lymphoid cell line derived from an orangutan with spontaneous myelomonocytic leukemia. herpesvirus has not previously been isolated from this species of higher ape. | 1977 | 198878 |
| [study of viremia in chronic human herpetic infection]. | attempts at virus isolation were made on the blood specimens from patients with relapsing herpesvirus infection. examinations of over 100 blood specimens from patients with various localizations of herpetic lesions yielded ii strains of herpesvirus. in all the cases the virus was isolated from a mixture of leukocytes with erythrocytes of the blood of patients. the method of cocultivation of blood leukocytes with cell cultures was most sensitive and yielded 7 herpesvirus isolates. the herpesvirus ... | 1977 | 198957 |
| [study of the antigenic properties of herpesvirus strains isolated from herpetic lesions at different sites]. | the antigenic properties of 15 strains of hepesvirus isolated from herpetic lesions of different localization were studied. the serotype of each strain was established by the neutralization tests with hyperimmune sera to the reference type 1 and 2 strains: the cross-neutralization tests revealed antigenic relationships between the strains of 1 and 2 serotypes. most strains isolated from lesions of the genitalia belonged to type 2, although one strain isolated in herpes genitalis belonged to type ... | 1977 | 198960 |
| atypical herpesvirus hominis type 2 infection in uremic patients receiving immunosuppressive therapy. | in four uremic patients (three renal transplant recipients and one with idiopathic thrombocytopenia), painful, initially vesicular lesions developed in the anogenital region while they were receiving immunosuppressive drug therapy. these lesions enlarged, coalesced and ulcerated, presenting a puzzling diagnostic problem. initial misdiagnoses often resulted in inappropriate antimicrobial therapy. routine cultures, histologic sections and tzanck preparations were seldom helpful. the correct diagno ... | 1977 | 199060 |
| equine rhinopneumonitis virus (herpesvirus type 1): attenuation in stable monkey cell line. | an isolate of virulent equine herpesvirus (ehv) type 1 was adapted to vero stable cell line by 13 serial passages at 37 c and 50 serial passages at 26 c. characteristics of the attenuated ehv-1 were found to be avirulent, but immunogenic in horses if injected intramuscularly. the attenuated virus was regularly isolated from peripheral leukocytes in inoculated horses, but was not recovered from nasal turbinate tissues. a mild leukopenia was noticed. the attenuated virus produced characteristic la ... | 1977 | 199093 |
| a study of cytomegalovirus, epstein-barr virus and herpesvirus hominis (types 1 and 2) antibody in institutionalized and non-institutionalized children. | in an attempt to demonstrate differences in antibody prevalence between free-living and institutionalized children, antibodies to cytomegalovirus (cmv), epstein-barr virus (ebv), and herpesvirus hominis (hvh), types 1 and 2, were assayed in 123 children. the children comprised three groups consisting of 41 institutionalized patients with down's syndrome (all non-disjunctive trisomy-g karyotype and equal numbers of age-, sex-, and race-matched non-mongoloid institutionalized subjects and non-inst ... | 1977 | 199558 |
| herpetic whitlow as part of genital virus infection. | lesions on fingers or hands caused by herpesvirus hominis have in the past been attributed to inoculation with virus-containing oropharyngeal secretions. often these "herpetic whitlows" were caused by h. hominis type 1 and occurred in medical personnel. a recent series of 13 recurrent "herpetic whitlows" yielded 11 isolates of h. hominis type 2 and only two of h. hominis type 1. none of the subjects was engaged in patient care, and none had oral or facial herpetic lesions. nine of the 11 infecti ... | 1977 | 199676 |
| [attempts at specific immunoprophylaxis against herpes mammillitis]. | a live cell culture adsorbate vaccine was produced against herpes mammillitis in cattle. comparative investigations were carried out on the immunogenic properties of four vaccines having different adjuvants--aluminum hydroxide, saponin, arlacell, and freund's adjuvant. all tested vaccines proved harmless and immunogenic for sensitive cattle, the highest immunogenic effect being produced by the vaccine that contained aluminum hydroxide and freund's adjuvant. the vaccinated animals reacted to immu ... | 1977 | 199986 |

| [virus-induced autoimmunity phenomena in experimental animals (author's transl)]. | it may happen that the virus infection causes changes of the immunogenicity of the host cells that may theoretically result in disturbances of the "self-recognition" of the organism. in this paper we report on the immunization of rabbits by autologous testes cells infected with herpes-virus hominis (hvh) types 1 and 2. | 1977 | 191276 |
| in vitro cytotoxicity of serum and peripheral blood leukocytes for equine herpesvirus type 1-infected target cells. | the immune response in horses following experimental infection with equine herpesvirus type 1 (ehv-1) was assessed by measuring cytotoxicity for ehv-1-infected target cells. a technique was developed, using [125i]5-iodo-2'-deoxyuridine ([125i]iudr)-labeled equine fetal kidney cells infected with ehv-1 as the target cells. it was shown that peripheral blood leukocytes from a recovered horse were capable of lysing target cells, as measured by the loss of radio-active label. following the experimen ... | 1977 | 189645 |
| isolation from a transmissible lymphoid tumour (tlt) lymphoblastoid cell line of a herpesvirus similar to marek's disease virus. | a chicken lymphoblastoid cell line (tlt)-6855 originally established from an avian oncornavirus-induced lymphoma (siegfried and olson, 1972) was studied for the presence and expression of marek's disease virus (mdv) genome. by nucleic acid hybridization a significant amount of mdv dna was found in this cell line. this virus dna, however, was not expressed in either virus-specific intracellular or membrane antigens or the md-associated tumour-specific surface antigen (matsa). moreover, mdv-specif ... | 1977 | 191411 |
| the presence of herpesvirus saimiri genomes in virus-transformed cells. | herpesvirus saimiri (h. salmiri) -transformed cells contained both types of viral dna, unique l-dna and highly repetetive h-dna. dna from spleen and lymph-node autopsies of two tumor-bearing marmoset monkeys contained 0.14-0.75% viral l-dna -and 0.115-1.08% h-dna. this amount of h-dna would be equivalent to the presence of 14-130 m-genomes per diploid tumor tissue cell. six virus-transformed lymphoid cell lines, two of them virus-producing, contained 0.69-2.27% h-dna and more than 0.72-1.95% l-d ... | 1977 | 191414 |
| cell-mediated immune responses in recurrent herpesvirus infections. i. lymphocyte proliferation assay. | studies in immunosuppressed and immunodeficient patients indicate that the cell-mediated immune response appears to be responsible for controlling reactivated herpesvirus infections. in this study, the various parameters of a herpesvirus (types 1 and 2) antigen specific lymphocyte proliferation assay were optimized and used to evaluate individuals with clinical, recurrent hsv-1 and hsv-2 infections. normal individuals with neutralizing antibody to hsv-1 or hsv-2 responded to virus antigen in cul ... | 1977 | 191528 |
| interaction of adenine arabinoside and host defense factors in experimental infections due to herpesvirus hominis. | the role of host immune functions in relation to the antiviral effects of adenine arabinoside (ara-a) and/or humoral antibodies in herpesvirus hominis infection was studied in four different mouse models (newborn swiss mice, three-week-old swiss mice, athymic nude [nu/nu] mice, and phenotypically normal [nu/+] littermates of nude mice). although the overall beneficial effects afforded by the administration of ara-a and/or humoral antibodies were similar, the degree of protection varied among the ... | 1977 | 191543 |
| lack of association between defective delinquents and antibody of herpesvirus hominis. | several groups have reported a relation between herpesvirus hominis infection and certain psychiatric disorders. we have investigated herpes antibody levels in chronic criminal offenders who were diagnosed as defective delinquents and in criminals who were not defective delinquents. we found no difference in the frequency of titers of herpesvirus type i or type 2 antibody in these groups. | 1977 | 191768 |

| effect of water temperature on a herpesvirus infection of sea turtles. | the role of water temperature in the induction and maintenance of a dermal herpesvirus infection (gray-patch disease) of young, green sea turtles (chelonia mydas) was studied under carefully controlled experimental conditions, in which the influence of other recognized stress factors was negligible. a nimals that were subjected to a gradual temperature increase from 25 to 30 degrees c, with subsequent maintenance at 30 degrees c, and those that were abruptly shifted from water at 25 degrees c to ... | 1977 | 192673 |
| antigenic relationships among several simian varicella-like viruses and varicella-zoster virus. | cross-neutralization and complement fixation tests demonstrated the immunological identity of the delta herpesvirus, the 592s virus, the liverpool vervet monkey virus, the herpesvirus of patas monkeys, and the medical lake macaque virus. these viruses were isolated from diverse outbreaks of varicella-like disease in simians and from various simian species. all of the simian viruses were shown to be related to human varicella-zoster (v-z) virus, as evidenced by the fact that immunization of monke ... | 1977 | 192676 |
| infectious causes of equine respiratory disease on ontario standardbred racetracks. | upper respiratory disease has been a serious problem in standardbred horses on racetracks in ontario, with outbreaks occurring once or twice annually in late winter and early spring seasons. to determine the causes of these epidemics, a 3-year investigation was carried out in which nasal swabs and serum samples were obtained at intervals from apparently healthy horses and from horses suffering from upper respiratory disease. the nasal swabs were used to isolate bacteria and viruses. the serum sa ... | 1977 | 192757 |
| comparative complement fixation and serum neutralization antibody titers to herpes simplex virus type 1 and herpesvirus simiae in macaca mulatta and humans. | the serological relationship of herpes simplex type 1 virus and herpesvirus simiae was studied. antibody titers to these viruses were determined in 163 macaca mulatta sera and 67 human sera by serum neutralization (sn) and complement fixation (cf) tests. both groups of sera were also tested by cf with envelope and capsid antigens of herpes simplex type 1. by sn, the majority of the monkeys and all of the humans had a higher titer to herpes simplex type 1 than to h. simiae. by cf, with crude anti ... | 1977 | 192762 |
| suppressed response to interferon inducation in mice infected with encephalomyocarditis virus, semliki forest virus, influenza a2 virus, herpesvirus hominis type 2, or murine cytomegalovirus. | mice infected with encephalomyocarditis virus, semliki forest virus, influenza a2 virus, herpesvirus hominis type 2, or murine cytomegalovirus developed a state of hyporeactivity to interferon induction. in general, the capacity of infected animals to produce interferon in response to inducers became progressively impaired during the course of infection. the severity and time of onset of hyporeactivity, however, were dependent upon the inducer and the nature of the viral infection. during viral ... | 1977 | 192804 |
| genital herpesvirus homonis infection in mice. ii. treatment with phosphonoacetic acid, adenine arabinoside, and adenine arabinoside 5'-monophosphate. | genital infection of mice with herpesvirus hominis type 2 provides an experimental model for screening potential antiviral chemotherapeutic agents before clinical trials in humans. intravaginal treatment with phosphonoacetic acid (at a dose of 500 mg/kg in saline or as a 5% cream) initiated 3 hr after inoculation with h. hominis type 2 completely inhibited viral replication in the genital tract and prevented subsequent mortality. although therapy initiated 24-72 hr after infection significantly ... | 1977 | 192805 |
| cellular immune responses to herpesviruses during treatment with adenine arabinoside. | thirteen patients severely infected with herpesvirus were treated with intravenous adenine arabinoside (ara-a), and two patients received placebo therapy. blastogenic and cytotoxic responses specific for the virus infecting each patient were determined before, during, and after treatment. blastogenic responses to three mitogens (phytohemagglutinin, pokeweed, and concanavalin-a) were examined, as were titers of viral antibody. in vitro responses during and after treatment with ara-a were unchange ... | 1977 | 192808 |
| immunomodulation of host resistance to experimental viral infections in mice: effects of corynebacterium acnes, corynebacterium parvum, and bacille calmette-guérin. | resistance to a representative group of experimental virual infections in mice was significantly enhanced by nonspecific modulation of host defense mechanisms. corynebacterium acnes, corynebacterium parvum, and bacille calmette-guérin were effective in enhancing host resistance. animals treated seven to 10 days before inoculation of virus were protected against a lethal infection with herpesvirus hominis type 2, encephalomyocarditis virus, murine cytomegalovirus, or semliki forest virus. the pro ... | 1977 | 192811 |
| thymidine transport in herpesvirus hominis type 1 and 2 infected bhk 21 cells. | increase of dthd-uptake 4 to 12 h after infection of bhk or primary rabbit kidney cells with herpesvirus hominis of type 1 or 2 can be considered as an early function of the virus genome, because the presence of cyd-ara does not prevent the increase of uptake. however, increase of uptake can be prevented by addition of actinomycin d and cycloheximide early in the synthetic cycle. two modes of uptake have been differentiated by kinetic analysis: at low substrate concentration dthd is taken up by ... | 1977 | 192842 |

| antiviral activity of some beta-diketones. 1. aryl alkyl diketones. in vitro activity against both rna and dna viruses. | the discovery that 4-[3-ethyl-6-[(3,4-methylenedioxy)phenyl]-3-hexenyl]-3,5-heptanedione (40) exhibited an in vitro inhibitory effect against equine rhinovirus led to a structure--activity study to establish the criteria for optimum activity. modification of the bridge included removal of the ethyl group and reduction of the double bond. the heptanedione was replaced with hexanedione and pentanedione with a minimal effect. the effect of replacing the heptanedione with beta-keto esters and monoke ... | 1977 | 195054 |
| antiviral activity of some beta-diketones. 2. aryloxy alkyl diketones. in vitro activity against both rna and dna viruses. | a series of aryloxy alkyl diketones ii was synthesized and screened in vitro for antiviral activity. the effect of various substituents on the phenyl ring, as well as the length of the alkyl bridge, was examined to establish the requirements for optimum activity. one of the most active members of the series, 4-[6-(2-chloro-4-methoxy)phenoxy]hexyl-3,5-heptanedione (56), exhibited a high level of activity against both dna and rna viruses in both the tissue culture and organ culture screens and was ... | 1977 | 195055 |
| herpesvirus saimiri-induced lymphoproliferative disease in howler monkeys. | four of 5 howler monkeys (alouatta caraya) experimentally infected with herpesvirus saimiri (hvs) developed a rapidly fatal malignant lymphoma accompanied by peripheral t-cell lymphocytosis. hvs was isolated from fresh and tissue cultured blood and tissue lymphocytes and from cell cultures derived from nonlymphoid organs. humoral antibodies against hvs-induced antigens were detected in the sera of the animals. the in vitro response of the peripheral blood lymphocytes to mitogenic stimulants was ... | 1977 | 195067 |
| lymphoproliferative diseases of fowl: jm-v leukemic lymphoblasts in cell culture. | jm-v leukemic lymphoblasts were established in cell culture. the cultured cells (jm-vlc cells) were transplantable in young chicks and produced a disease indistinguishable from jm-v lymphoblastic leukemia as initiated by whole-blood inoculation. jm-vlc cells maintained a normal female karyotype through 13 passages in rhode island red cockerels. with the use of jm-v antisera and antisera from birds with naturally occurring marek's disease (md), specific antigens were detected on the surfaces of l ... | 1977 | 195070 |
| regulation of herpesvirus macromolecular synthesis. vi. synthesis and modification of viral polypeptides in enucleated cells. | cells were enucleated with cytochalasin b after infection with herpes simplex virus 1. when protein synthesis was blocked by cycloheximide from the time of infection, mrna for viral alpha-infected cell polypeptides (icp) 4, 0, and 27 accumulated in the cytoplasm and was expressed after the removal of both drug and nucleus. a host protein, icp 22, whose synthesis is stimulated in intact cells, was not made, and viral protein icp4, which is normally modified to a form that migrates more slowly in ... | 1977 | 195087 |
| replication of herpesvirus dna. iii. rate of dna elongation. | the rate of pseudorabies virus dna elongation was measured by three different techniques: density shift experiments, radioautography examined by light microscopy, and radioautography examined by electron microscopy. the rate of the fork movement at 37 degrees c was estimated to be approximately 1 micron/min. | 1977 | 195088 |
| episomal viral dna in a herpesvirus saimiri-transformed lymphoid cell line. | the lymphoid cell line #1670 has been derived from the infiltrated spleen of a tumor-bearing marmoset monkey infected with herpesvirus saimiri. the cells contain both types of h. saimiri dna, unique light (l-) dna (36% cytosine plus guanine) and repetitive heavy (h-) dna (71% cytosine plus guanine), without producing infectious virus. viral dna was found to persist in these cells as nonintegrated circular dna molecules. closed circular superhelical viral dna molecules were isolated by three subs ... | 1977 | 195090 |
| experimental cytomegalovirus infection and the developing mouse inner ear: in vivo and in vitro studies. | mouse cytomegalovirus causes perilabyrinthitis in the cochlea following intracranial inoculation of the newborn mouse. in spite of infection of cranial nerve ganglion cells and schwann cells the organ of corti achieves normal adult morphology including efferent nerve endings. no involvement of neuroaxons is seen. in comparison human cytomegalovirus infection causes endolabyrinthitis without involving periotic connective tissues or nerves even in the presence of meningoencephalitis. the lack of e ... | 1977 | 195137 |
| spontaneous mutations in ageing human cells: studies using a herpesvirus probe. | several fundamental theories of ageing postulate that spontaneous mutations increase in somatic cells as they age. this has not until recently been directly tested in mammalian cells, because of the problem of estimating mutation rate in declining cell populations. one possible approach is to infect cells with lytic virus and measure the mutation frequency in virus made by the cellular machinery. three temperature-sensitive mutants of herpesvirus were used to infect human fibroblasts in vitro. t ... | 1977 | 195146 |
| induction of deoxycytidine deaminase activity in mammalian cell lines by infection with herpes simplex virus type 1. | herpes simplex virus type 1 induces deoxycytidine deaminase (cytidine/deoxycytidine aminohydrolase, ec 3.5.4.5) activity when it lytically infects a number of mammalian cell lines. the deaminase activity is induced in a mouse cell line that is deficient in this enzyme. the induction of the enzyme in this mutant cell line does not occur in the presence of actinomycin d and the induced enzyme is more thermolabile than the enzyme of the wild-type mouse cell line. furthermore, a new deoxycytidine de ... | 1977 | 193115 |
