| zosteriform spread of herpes simplex virus type 2 genital infection in the guinea-pig. | a model of herpes simplex virus type 2 (hsv-2) infection was developed in the guinea-pig that permits investigation of the role of neural spread of virus in the pathogenesis of genital skin disease. after hsv-2 inoculation of an abraded area lateral to the external genital skin, virus was first detected in the ipsilateral (to the inoculation site) peripheral nerves or genital skin on day 2 or 3 post-inoculation followed by detection in the ipsilateral dorsal root ganglia and spinal cord on day 3 ... | 1986 | 3018127 |
| genetically determined difference in the antiviral action of alpha/beta interferon in cells from mice resistant or susceptible to herpes simplex virus type 2. | resistance of mice to infection with herpes simplex virus type 2 (hsv-2) is genetically determined. embryonic cells from susceptible balb/c and resistant c57bl/6 mice were equally sensitive to infection with hsv-2 as judged by plaque area, plaquing efficiency, endpoint titration and virus yield. cells from c57bl/6 mice showed a higher sensitivity than cells from balb/c mice to the protective action of two preparations of alpha/beta interferon against challenge with hsv-2. this was evident both f ... | 1986 | 3018128 |

| antiherpetic effects of a human alpha interferon analog, ifn-alpha con1, in hamsters. | the efficacy of a novel consensus form of human alpha interferon designated ifn-alpha con1 was evaluated against herpesvirus infections in vitro and in vivo. at comparable antiviral concentrations, natural lymphoblastoid ifn, ifn-alpha con1, the molecular subtype ifn-alpha, and the hybrid ifn-alpha ad(bgl) obtained by recombinant dna methods conferred similar protection against herpes simplex virus type 1 and type 2 (hsv-2) infections of human cells in vitro. whereas 7 x 10(5) u of ifn-alpha ad( ... | 1986 | 3019238 |
| specific transfer factor protects mice against lethal challenge with herpes simplex virus. | bovine transfer factor (tfd) specific to herpes simplex virus (hsv)1 or to hsv2 was prepared by immunizing calves with the corresponding virus. the tfd preparations were then injected into swiss mice in an attempt to protect them against a subsequent lethal challenge with hsv1 or hsv2 virus. it was thus shown that injection of anti-hsv tfd protects the mice against the corresponding hsv virus, whereas the injection of a nonspecific tfd (anti-cmv) fails to protect against a challenge with hsv1. f ... | 1986 | 3019568 |
| human papillomavirus in clinically and histologically normal tissue of patients with genital cancer. | to study the association of human papillomavirus (hpv) and herpes simplex virus (hsv) with genital cancer, we collected specimens of cervical, vulvar, endometrial, and vaginal tumors at the time of operation in patients with cancer. in some patients, matched internal-control (histologically normal) tissue was also collected. dna extracted from the tissue was probed with radiolabeled hpv type 16 dna, hpv type 18 dna, and cloned fragments of hsv type 2 dna. hybridization to the hindiiia clone of h ... | 1986 | 3020404 |

| photodynamic inactivation of influenza and herpes viruses by hematoporphyrin. | hematoporphyrin (hp), at concentrations as low as 0.5 microgram/ml, was found to inhibit the in vitro replication of influenza a and herpes simplex viruses, but not of several other viruses. the effect required exposure of the viruses or cells to visible light and was demonstrable when hp was administered shortly before virus inoculation or during the infection. in studies on the mechanism of action of hp, we found that in the presence of light, hp caused decomposition of gmp but not of various ... | 1987 | 3026246 |
| evidence that neomycin inhibits hsv 1 infection of bhk cells. | the effect of neomycin on the herpes simplex virus (hsv) type 1 and 2 infection of baby hamster kidney cells was studied. neomycin concentrations of 3 mm or more caused a more than 90% inhibition of hsv 1 proliferation, while it had no effect on hsv 2 proliferation, measured as plaque-forming units. furthermore, neomycin must be present at the time of infection in order to exert full effect, addition 1 hour postinfection was comparable to untreated cells. this indicates that neomycin may specifi ... | 1986 | 3026374 |
