| a marmoset t lymphoma which functions as a human amplifier t cell. | a long-term in vitro grown t cell line derived from a cotton-topped marmoset (saguinus oedipus) infected with herpesvirus saimiri was fond to share surface antigens with human amplifier t cells and to augment the capacity of human b cells to secrete immunoglobulin. this is the first demonstration of t/b collaboration across such a large phylogenetic barrier and might have interesting implications for understanding the nature of molecular interactions mediating cell/cell cooperation. | 1981 | 6801144 |
| changes in immune response during responses in ms patients. | changes in clinical status and in two measures of immune function were followed for 21 months (median) in 106 multiple sclerosis (ms) patients and cohabitant controls. antibody titers to measles, cytomegalovirus, and herpesvirus 1 and 2, and leukocyte migration inhibition indexes (lmis) to measles and streptokinase/streptodornase (sksd) were measured at 3- to 6-month intervals and at time of exacerbation in the index case. there were 36 exacerbations in 25 patients. mean baseline antibody titers ... | 1981 | 6452588 |
| latent infections with marek's disease virus and turkey herpesvirus. | the number of plaque-forming units (pfu) from lymphocytes latently infected with oncogenic (ga-5) or nononcogenic (sb-1) marek's disease virus (mdv) was decreased after complement lysis with antisera against thymus-derived lymphocytes or bursa-derived lymphocytes; an additive effect with dual treatment was observed. complement lysis with antisera against marek's disease tumor-associated surface antigen (putative tumor antigen) had little effect, which suggests an absence of the antigen on latent ... | 1981 | 6259403 |
| herpesvirus-induced antigens in squamous-cell carcinoma in situ of the vulva. | antigens induced by herpes simplex virus type 2 (hsv2) were found to be associated with squamous-cell carcinoma in situ of the vulva in nine of 10 patients. the hsv2-induced antigens are dna-binding proteins that are normally present in the nuclei of infected cells, but in the cells of the carcinomas in situ they were found in the cytoplasm. whole-virion structural antigens were not present, although there was serologic evidence of previous hsv2 infection in patients tested for the presence of a ... | 1981 | 6265780 |
| differentiation of respiratory and abortigenic isolates of equine herpesvirus 1 by restriction endonucleases. | viruses classified by immunologic criteria as equine herpesvirus 1 cause respiratory disease and abortion in horses. restriction endonuclease analyses of the dna's of viruses from animals with respiratory disease and from aborted fetuses show that the patterns for respiratory viruses, while similar to each other, are entirely different from the patterns for fetal viruses. it is therefore proposed that the dna restriction endonuclease patterns of fetal and respiratory viruses analyzed in this stu ... | 1981 | 6270790 |
| enhancement of varicella-zoster virus replication in cultured human embryonic lung cells treated with the pesticide carbaryl. | in studies designed to determine the factors responsible for control of herpesvirus replicaton in an infected cell, we examined the interaction of varicella-zoster (vz) virus-infected human embryonic lung cells with the pesticide carbaryl. the replication of the cell-associated vz virus was enhanced 2- to 13-fold as compared to control cultures in sevin 4 oil-treated cultures and in cultures treated with the pesticide's active ingredient, carbaryl. the replication of vz virus in cultures teated ... | 1981 | 6261690 |
| regulation of herpesvirus macromolecular synthesis: temporal order of transcription of alpha genes is not dependent on the stringency of inhibition of protein synthesis. | operationally, alpha genes of herpes simplex virus 1 were defined on the basis of the observations that they are the earliest genes expressed in the infected cell and that the transcription, processing, accumulation of the mrna's in the infected cell cytoplasm can take place in the presence of inhibitors of protein synthesis, such as cycloheximide. in these studies, we translated in vitro the viral mrna's extracted from cells infected maintained in the presence of cycloheximide, emetine, or anis ... | 1981 | 6270385 |
| selective inhibition of herpesvirus deoxyribonucleic acid synthesis by acycloguanosine, 2'-fluoro-5-iodo-aracytosine, and (e)-5-(2-bromovinyl)-2'-deoxyuridine. | the selectivity of inhibition of herpesvirus deoxyribonucleic acid synthesis by acycloguanosine, 2'-fluoro-5-iodo-aracytosine, and (e)-5-(2-bromovinyl)-2'-deoxyuridine was determined by isopycnic banding of (32)p-labeled deoxyribonucleic acid from herpesvirus-infected and uninfected cells. | 1981 | 6271053 |

| the relationship of herpesvirus to carcinoma of the prostate. | a laboratory based epidemiologic study was done to determine the possible relationship of herpesvirus type 2 to carcinoma of the prostate. a total of 305 patients (224 with benign prostatic hypertrophy and 81 with prostatic carcinoma) who underwent transurethral resection of the prostate was studied. viral cultures were obtained from urethral swabs and urine preoperatively. prostatic tissue removed at operation was grown as tissue explants, using a monolayer cell culture technique, and examined ... | 1981 | 6259379 |
| infection of sheep and goats with bovid herpesvirus 2. | sheep and goats were shown to be susceptible to experimental infection with bovid herpesvirus 2 (bhv2), administered by either the intradermal or intravenous route. lesions developing in sheep following intradermal inoculation of virus were similar to those in cattle inoculated intradermally, whereas the lesions in goats resolved without ulceration or scabbing. disseminated circumscribed skin lesions developed in sheep and goats given bhv2 by the intravenous route. these lesions resolved in four ... | 1981 | 6281868 |
| effects of canavanine treatment on herpesvirus morphogenesis in cultured cells. | l-canavanine, a naturally occurring analog of arginine, effectively inhibited the morphogenesis of herpes simplex virus (hsv) and human cytomegalovirus (hcmv) when added at the time of infection, but allowed the expression of several cytopathic changes. exposure to canavanine at progressively later times ultimately led to qualitatively normal virion maturation. under no conditions were morphologically aberrant viral particles observed. however, hsv-infected cells treated at 3 h postinfection or ... | 1981 | 6282774 |
| antibody pattern to human cytomegalovirus in patients with adenocarcinoma of the colon. | the role of human cytomegalovirus (cmv) was examined according to serological patterns in 37 patients with adenocarcinoma of the colon (acc). the sera were examined for the presence of igg antibodies by the immunoperoxidase antibody to membrane antigens (ipama) method and by the complement-fixation (cf) test. antibody determinations were also performed by the ipama method for three other members of the herpesvirus group: epstein-barr virus (ebv), herpes simplex virus (hsv) and varicella-zoster ... | 1981 | 6282775 |
| serologic and molecular comparisons of several equine herpesvirus type 1 strains. | the molecular and serologic relatedness of 2 recent respiratory tract isolates of equine herpesvirus type 1, designated t1 and t2, were compared with the army 183, kentucky-a hamster-adapted (kya-ha), and l-m cell-adapted (kya-lm) strains. electrophoresis in polyacrylamide gels revealed differences in virion structural proteins among 4 purified strains. seven envelope glycoproteins (molecular weight of 93,000, 65,000, 62,000, 60,000, 36,000, 20,000, and 18,000) corresponding to virion proteins 1 ... | 1981 | 6280520 |

| a simple in vitro differentiation between turkey herpesvirus and marek's disease virus. | the growth and plaque formation by turkey herpesvirus (hvt) amd marek's disease herpesvirus (mdhv) were examined in qt35 cells, a continuous fibroblast cell line derived from chemically induced tumors of japanese quail. hvt grew and formed plaques consistently in qt35 cells when inoculated with cell-culture-propagated virus or peripheral mononuclear leukocytes (pml) from chickens that had been inoculated with hvt. both oncogenic and nononcogenic strains of mdhv, however, failed to grow and induc ... | 1981 | 6279072 |
| natural killer cell activity in chickens exposed to marek's disease virus: inhibition of activity in susceptible chickens and enhancement of activity in resistant and vaccinated chickens. | chickens of 2 genetic lines (lines p and n) were inoculated with a pathogenic strain of marek's disease (md) virus (mdv) and chronologically examined for disease response and natural killer (nk) cell expression. the nk cell reactivity was assayed in an in vitro cytotoxicity assay in which effector cells from the spleen of test chickens were reacted with 51cr-labeled lscc-rp9 target cells. chickens of line p developed progressive debilitating disease and a high incidence of gross tumors and death ... | 1981 | 6279075 |
| nucleotide sequence of the thymidine kinase gene of herpes simplex virus type 1. | we have determined the complete nucleotide sequence of the thymidine kinase (atp:thymidine 5' phosphotransferase, ec 2.7.1.21) gene of herpes simplex virus type 1 strain cl101 from a plasmid clone of viral dna derived by enquist et al. [enquist, l. w., vande woude, g. f., wagner, m., smiley, j. r. & summers, w. c. (1979) gene 7, 335-342]. a cdna copy of the 5' end of thymidine kinase mrna was also analyzed to locate the transcribed sequences. the transcribed portion of the gene is approximately ... | 1981 | 6262799 |
| spontaneous generalized herpesvirus hominis infection of a lowland gorilla (gorilla gorilla gorilla). | a 13-day-old lowland gorilla died from a generalized herpesvirus infection shortly after the onset of clinical signs. the pathologic-anatomical findings were compatible with those described for generalized herpes simplex infection in the human neonate. electron microscopic examination of lung tissue revealed the presence of herpesvirus which was identified with the fluorescent antibody technique as herpes simplex virus type i. tests with related sera of the herpes group (varicella, herpesvirus-b ... | 1981 | 6279853 |

| proteins specified by bovine herpesvirus 1 (infectious bovine rhinotracheitis virus). | an electrophoretic analysis of radioactively labeled, purified, "empty" and dna-containing infectious bovine rhinotracheitis virions revealed the presence of 25 to 33 structural (virion) polypeptides. a total of 11 of these polypeptides could be labeled with [3h]glucosamine and were identified as glycoproteins. in addition to the 25 structural polypeptides, infectious bovine rhinotracheitis virus infected cells also contained at least 15 nonstructural (nonvirion) polypeptides that were not prese ... | 1981 | 6275094 |
| studies on benzhydrazone, a specific inhibitor of herpesvirus glycoprotein synthesis. size distribution of glycopeptides and endo-beta-n-acetylglucosaminidase-h treatment. | benzhydrazone is a bis-amidinohydrazone derivative which specifically hinders the formation of herpes simplex virus (hsv) glycoproteins. in this study we present some structural features of the oligosaccharide chains of herpesvirus glycoproteins synthesized in cells incubated with the inhibitor. gel filtration analysis of glycopeptides, obtained through exhaustive pronase-digestion of infected cells after a long or a short labeling with 14c-glucosamine, showed that benzhydrazone reduced the appe ... | 1981 | 6275822 |
| postexposure immunoprophylaxis against b virus (herpesvirus simiae) infection. | local infiltration of antiserum into sites inoculated with b virus protected rabbits from an otherwise fatal encephalomyelitis. treatment was effective when delayed for six hours but not after 24 hours. homologous rabbit antisera were more effective than heterologous monkey antisera, and protection was unrelated to neutralisation titres. protection apparently depended not on neutralisation of inoculated virus but on destruction of infected cells before they produced progeny virus. normal human i ... | 1981 | 6275934 |

| episomal and nonepisomal herpesvirus dna in lymphoid tumor cell lines. | tumor cell lines derived from herpesvirus saimiri (h. saimiri)- and herpesvirus ateles (h. ateles)-induced lymphomas of new world primates and rabbits contain multiple copies of viral genomes. partial denaturation mapping and blot hybridizations of episomal dna from lymphoid tumor cell line no. 1670 showed that a 12.5md-fragment is missing which represents the ecori d- and h-fragments of virion l-dna. however, the missing piece can be demonstrated in total cellular dna by reassociation kinetics, ... | 1981 | 6274746 |
| stabilization of isometric dna viruses against thermoinactivation by lowered ionic strength. | the thermostability of isometric dna viruses increases, if the ionic strength is diminished before heating. when unpurified virus material from cell cultures is heated under conditions (temperature, time) which lead to a reduction in infectivity by 3 to 4 log10, this loss in titer is 1 to 3 log10 less, if the ionic strength is decreased by diluting the material in dist. water (1:100) before heating. a dilution in eagle's mem (1:100) or a previous dialysis against water does not have the same eff ... | 1981 | 6271099 |
| herpesvirus tamarinus and its relation to herpes simplex virus. | we have characterized herpesvirus tamarinus (ht), a virus of new world primates related to herpes simplex virus. ht virion dna cross-hybridized appreciably with herpes simplex virus type 1 (hsv-1) dna. the ht-hsv-1 cross-hybridizing dna sequences were distributed over the length of the genome; some dna sequences, however, were apparently more homologous than others. ht virion dna was estimated from the sum of restriction endonuclease fragments to have a mol. wt. 98 x 10(6). only 1 molar fragment ... | 1981 | 6271910 |
| retinoid-induced growth inhibition of herpesvirus-transformed marmoset lymphoblastoid cell lines. | the in vitro proliferation of herpesvirus-transformed marmoset lymphoblastoid cell lines (lcl) was inhibited by retinoic acid and retinyl acetate. both herpesvirus-ateles-and herpesvirus-saimiri-transformed lcl with t-cell characteristics and epstein-barr-transformed lcl with b-cell markers were more sensitive to retinoic acid than to retinyl acetate. inhibition of lcl proliferation was dependent on retinoid concentration and became apparent only after 3-4 days of exposure. in vitro assays for m ... | 1981 | 6272171 |
| activity of trifluorothymidine against cytomegalovirus. | trifluorothymidine (tft) was tested for antiviral activity against mouse cytomegalovirus (mcmv) and human cytomegalovirus (hcmv) in one-step replication assays. the tft concentration required to reduce virus yield by 50% (id50) was 0.22 microm for mcmv and 0.012 microm for hcmv. the antiviral activity of tft against mcmv was reversed by addition of equimolar thymidine, and no antiviral activity was demonstrable in a host cell line lacking thymidine kinase. thus, tft's anti-mcmv activity is depen ... | 1981 | 6272627 |

| [experimentally induced herpesvirus sa 8-pneumonia (bronchopneumonia) in kenya baboons (papio cynocephalus) (author's transl)]. | captive baboons of three age groups were experimentally infected with herpesvirus sa 8-strain 0430. intravenous inoculation of the virus induced minor, transient, interstitial pneumonia of a nonspecific type in newborn baboons. intratracheal inoculation, in contrast, invariably produced multifocal or diffuse necrotizing inclusion body bronchopneumonia within two days in newborn, two months and one year old baboons. differences in the outcome of the experimental intratracheal infections were noti ... | 1981 | 6269276 |
| efficacy of acyclovir against mouse cytomegalovirus in vivo. | acyclovir reduced mortality and organ virus titers in mice inoculated intraperitoneally with 10 50% lethal doses of mouse cytomegalovirus. this susceptibility to acyclovir of a herpesvirus which lacks thymidine kinase is surprising. alternative phosphorylating enzymes may account for this susceptibility. | 1981 | 6269490 |

| immunofluorescent staining of nuclear antigen in lymphoid cells transformed by herpesvirus papio (hvp). | an improved fixation method for antigen detection in lymphoblastoid cells is described. herpesvirus papio nuclear antigen (hupna) could be stained in several transformed lymphoid cell lines by anti-complement immunofluorescence (acif). antibody to hupna was detected in many human sera containing antibodies to epstein-barr virus capsid and nuclear antigen (ebna). rheumatoid arthritis sera showed a high incidence of both anti-ebna and anti-hupna antibodies. | 1981 | 6270210 |
| morphological components of herpesvirus. iii. localization of herpes simplex virus type 1 nucleocapsid polypeptides by immune electron microscopy. | herpes simplex virus type 1 (hsv-1) nucleocapsids were observed in the electron microscope after their reaction with igg's purified from the sera of rabbits immunized with the individual nucleocapsid polypeptides. the combining sites of nc1, the major capsid protein (mol. wt. 154k), were distributed over the entire capsid surface. this result provides further evidence that nc1 represents the major hexamer constituent. nc2 (mol. wt. 50k) was less widely distributed and appeared to be located at c ... | 1981 | 6270247 |
| thymidine kinase not required for antiviral activity of acyclovir against mouse cytomegalovirus. | previous studies of herpesvirus infections have indicated that a virus-specified thymidine kinase is required for the initial phosphorylation of acyclovir [acycloguanosine or 9-(2-hydroxyethoxymethyl)guanine] in the formation of acycloguanosine triphosphate. the latter compound accumulates in infected cells and competitively inhibits the viral dna polymerase. we found that mouse cytomegalovirus, which does not express a thymidine kinase, was sensitive to the antiviral effects of acyclovir at a 5 ... | 1981 | 6270357 |
| herpes simplex virus types 1 and 2 completely help adenovirus-associated virus replication. | in addition to adenoviruses, which are capable of completely helping adenovirus-associated virus (aav) multiplication, only herpesviruses are known to provide any aav helper activity, but this activity has been thought to be partial (i.e., aav dna, rna, and protein syntheses are induced, but infectious particles are not assembled). in this study, however, we show that herpes simplex virus type 1 (hsv-1) and type 2 (hsv-2) are in fact complete aav helpers and that aav type 2 (aav2) infectivity yi ... | 1981 | 6270377 |
| canine viruses and multiple sclerosis. | serum and cerebrospinal fluid from multiple sclerosis (ms) patients and control subjects were tested and compared for presence and titer of neutralizing antibody against the most common canine viruses. canine viruses included canine distemper virus (cdv), canine adenovirus 1 (cav-1), canine parainfluenza virus (cpiv), canine herpesvirus (chv), canine coronavirus (ccv), and canine parvovirus (cpv). neutralizing titers against measles virus (mv) and human adenovirus 8 (ha8) were also tested. signi ... | 1981 | 6267515 |
| serological responses to mycoplasma synoviae in chickens infected with virulent or avirulent strains of marek's disease virus. | the pathogenicity and immunosuppressive capability of five strains of marek's disease herpesvirus (mdhv) was examined. three of the strains (ala, miss, ncs) were isolated from flocks experiencing vaccine breaks while the other two strains (ga, hn) represented prototype virulent and avirulent viruses. pathogenicity of mdhv strains was evaluated on their ability to cause mortality, their ability to cause gross or microscopic lesions, and the median latent period to death (mlpd) for each strain. an ... | 1981 | 6267580 |

| an interchangeable elisa for cytomegalovirus antigen and antibody. | an enzyme-linked immunosorbent assay (elisa) was developed to demonstrate cytomegalovirus (cmv) antibodies and antigen. a nuclear antigen from cmv-infected cells was used for detection of igg and igm antibodies. significant rises of cmv-igg and significant levels of cmv-igm were found in sera from patients with acute cmv only, and not with other herpesvirus infections. cmv antigens were demonstrated in cells and in culture medium by a sandwich or by an inhibition elisa technique. in the sandwich ... | 1981 | 6262352 |
| two small rnas encoded by epstein-barr virus and complexed with protein are precipitated by antibodies from patients with systemic lupus erythematosus. | primate cells harboring the epstein-barr virus (ebv) genome synthesize large amounts of two small rnas:eber 1 and eber 2 (ebv-encoded rna). these rnas are approximately 180 nucleotides long, possess 5' pppa termini, and lack poly(a). they have different t1 and pancreatic rnase digestion fingerprints. they are not found in normal b lymphocytes, in transformed b lymphocytes that lack ebv dna, in t lymphocytes transformed by herpesvirus ateles, or in a variety of other nonlymphoid mammalian cells. ... | 1981 | 6262773 |
| experimental study of contagious paralysis of pigeons. | a study of the clinical and pathological changes in pigeons experimentally inoculated with a herpesvirus isolated recently from natural cases of a condition termed contagious paralysis was carried out. signs and pathological findings similar to those recorded in natural cases were produced after inoculation of the isolate via different routes. the incubation period differed according to the route of inoculation from 2 to 10 days and the course of the disease from 5 to 21 days. the mortality rang ... | 1981 | 6262960 |
| mortalities associated with herpesvirus infection in captive macropods. | fatal cases of herpesvirus infection in a quokka (setonix brachyurus), eight grey dorcopsis wallabies (dorcopsis muelleri luctuosa) in two separate outbreaks, as well as presumptive fatal herpesvirus infection in a western grey kangaroo (macropus fuliginosus) are described. all were captive animals and deaths were preceded by a period of stress. lesions occurred most often in alimentary tract epithelium, respiratory tract, skin, genital epithelium, conjunctivae, liver and adrenal cortex. herpesv ... | 1981 | 6264169 |
| detection of antibodies to herpesvirus simiae and herpesvirus hominis in nonhuman primates. | sera from nonhuman primates, predominantly macaca species, were assayed by a serum neutralization test for antibodies to antigenically related herpesvirus simiae (b virus) and herpesvirus hominis type 1. the data indicate that there would have been approximately 50% error in the diagnosis of herpesvirus simiae infection if these sera had been tested only against herpesvirus hominis antigen. the role of active guinea pig complement in the serum neutralization test was also evaluated and found to ... | 1981 | 6264222 |
| detailed characterization of the mrna mapping in the hindiii fragment k region of the herpes simplex virus type 1 genome. | we have isolated as recombinant dna clones, in the plasmid pbr322, regions of the herpesvirus type 1 genome spanning the region between 0.53 and 0.6 on the prototypical arrangement. this 11,000-base-pair region corresponds to 10% of the large unique region and encodes five major and several minor mrna species abundant at different times after infection, which range in length from 7 to 1 kilobase. in this report, we have used rna transfer blots and s1 nuclease digestion of hybrids between viral d ... | 1981 | 6262521 |
| herpesvirus-transformed cytotoxic t-cell lines. | investigations of cellular cytotoxicity of the immune system are hampered by the lack of continuously growing, transformed cell lines which express a cytotoxic potential. here we describe cytotoxic cell lines from the cotton-topped marmoset monkey, transformed by herpesvirus ateles (hva) or herpesvirus saimiri (hvs), which can kill certain target cells in a short-term in vitro test. hva/hvs-transformed cells have earlier been classified as belonging to the t-cell lineage in contrast to epstein-b ... | 1981 | 6262648 |
| serological responses to the cell associated herpesvirus and the manx calicivirus of spf male cats with herpesvirus-induced urolithiasis. | the feline cell associated herpesvirus (cahv), but not the manx calicivirus, was previously reported to induce urolithiasis in specific pathogen free (spf) cats. serum neutralization (sn) antibody studies, reported here, revealed that the experimental spf cats did not have sn antibodies either against the cahv or the manx calicivirus in preinoculation serum samples. however, all cats inoculated with the cahv (either alone or in combination with the manx virus) developed sn antibodies against the ... | 1981 | 6262014 |
| multifocal varicella-zoster virus leukoencephalitis temporally remote from herpes zoster. | two patients with cancer, one with hodgkin's disease and the other with a granulosa cell tumor of the ovary, developed a progressive, eventually fatal infection of the central nervous system exhibiting multifocal symptoms and signs. pathologically, gross abnormalities of the brain resembled those in progressive multifocal leukoencephalopathy (pml), with discrete and confluent plaque-like lesions concentrated in the white matter, particularly along the gray-white junction. microscopically, pathol ... | 1981 | 6261672 |
| herpesvirus papio dna is similar in organization to epstein-barr virus dna. | ecori, hindii, sali, nd xbai restriction endonuclease maps of herpesvirus papio (hvpapio) dna were derived by determining the fragment sizes and the linkage relationships between fragments generated by the different enzymes. the data indicate that hvpapio dna has a single molecular arrangement which is similar to that of epstein-barr virus dna. the size of the dna was 110 x 10(6) to 114 x 10(6) daltons. restriction fragments from both ends varied in the number of repeats of a 4 x 10(5)-dalton se ... | 1981 | 6261014 |
| linkage map of the fragments of herpesvirus papio dna. | herpesvirus papio (hvp), an epstein-barr-like virus, causes lymphoblastoid disease in baboons. the physical map of hvp dna was constructed for the fragments produced by cleavage of hvp dna with restriction endonucleases ecori, hindiii, sali, and pvui, which produced 12, 12, 10, and 4 fragments, respectively. the total molecular size of hvp dna was calculated as close to 110 megadaltons. the following methods were used for construction of the map; (i) fragments near the ends of hvp dna were ident ... | 1981 | 6261015 |
| colinearity between the dnas of epstein-barr virus and herpesvirus papio. | epstein barr virus (ebv) and herpesvirus papio (hvpapio) dnas share a common format and 40% homology. labeled cloned fragments of ebv dna were hybridized to blots of xbai, ecori, hindiii, and sali fragments of hvpapio dna. ebv fragments which mapped from 2 x 10(6) to 54 x 10(6) and from 59 x 10(6) to 106 x 10(6) daltons hybridized to fragments at identical map positions in hvpapio dna. regions of nonhomology were demonstrated at 0 x 10(6) to 2 x 10(6), 54 x 10(6) to 59 10(6), and 106 x 10(6) to ... | 1981 | 6261021 |
| viral-induced leukocyte interferon in vesicle fluid from lesions of recurrent herpes labialis. | antiviral activity characterized as human interferon (huifn) was demonstrated in vesicle fluid from lesions of recurrent herpes labialis in 18 of 19 otherwise healthy patients. high titers (geometric mean, 29,200 units) were present during the early course of lesion development. antiviral activity in vesicle fluid was neutralized by antibody to leukocyte (types i) huifn (huifn-alpha) in the eight patients in whom it was tested. these results indicate that huifn-alpha is present in the local lesi ... | 1981 | 6165784 |
| complement requirement for virus neutralization by antibody and reduced serum complement levels associated with experimental equine herpesvirus 1 infection. | pony foals, negative for detectable serum-neutralizing antibody to equine herpesvirus 1 by the standard tube-culture virus neutralization test, were experimentally infected with equine herpesvirus 1. complement-requiring (cr) and non-complement-requiring (ncr) serum-neutralizing antibodies were evaluated in preinfection and postinfection sera by means of a complement-enhanced plaque reduction assay. low levels of cr antibodies were found in the preinfection sera of only group ii ponies. upon inf ... | 1981 | 6260672 |
