The localization of anti-IBR and anti-PI-3 activity in the serum and nasal secretory immunoglobulins following intranasal immunization of cattle with a mixed vaccine (IBR-PI-3, MLV, TCO) was studied and was found to reside in the nasal secretory IgA,

9-β- d -Arabinofuranosyladenine (Ara-A) effectively inhibited the production of infectious vesicular stomatitis virus (VSV) in MDBK cells. Furthermore, inhibition was shown to begin as early as the first 3 hr of infection. Studies employing 3 H- l -

When infectious bovine rhinotracheitis (IBR) virus-infected MDBK cells were overlaid with Eagle's MEM lacking a single amino acid, virus yields were lowered. The omission of either arginine or leucine greatly reduced viral yields; but, further supple

The production of vesicular stomatitis virus in MDBK cells has been shown to be markedly enhanced by the addition of whole serum to maintenance media. Maximum virus production occurred in the presence of human and fetal calf sera. When different seru

Summary The addition of either isatin-β-thiosemicarbazone (IBT) or its N-methyl derivative effectively inhibited the multiplication of various isolates of infectious bovine rhinotracheitis virus. Treatment of infected cultures with IBT early or late

Trypsin enhancement of parainfluenza-3 virus infectivity in HEp-2 cells was demonstrated. A substantial enhancement of infectivity was observed when cell cultures were exposed to trypsin during the adsorption period or when subcultured with trypsin l

Neutral protease activity of allantoic fluid from embryonated chicken eggs was quantified during the course of influenza virus infection. Antigenic subtypes of influenza A viruses selected for study were H1N1 strains PR/8/34, Brazil/8/78, FM/1/47, th

The levels of neutral protease activity associated with allantoic and amniotic fluids of embryonated eggs during the replication of influenza strains A/PR/8/34 (H1N1) and A/turkey/Ontario/7732/66 (H5N9) were investigated. A sensitive fluorometric tec

Allantoic fluids harvested from embryonated chicken eggs infected with reference strains of influenza A viruses were analysed for subtilisin inhibitor activity. While all acid heat-treated and nontreated virus-infected fluids could reduce subtilisin
