Temperature-Sensitive Live-Attenuated Canine Influenza Virus H3N8 Vaccine.
Canine influenza is a respiratory disease of dogs caused by canine influenza virus (CIV). CIV subtypes responsible for influenza in dogs include H3N8, which originated from the transfer of H3N8 equine influenza virus to dogs; and the H3N2 CIV, which is an avian-origin virus that adapted to infect dogs. Influenza infections are most effectively prevented through vaccination to reduce transmissio...
متن کاملRapid onset of protection against infectious bovine rhinotracheitis with a modified-live virus multivalent vaccine.
This study provides evidence that subcutaneous vaccination of cattle with a commercially available modified-live virus combination vaccine can help reduce clinical signs associated with infectious bovine rhinotracheitis infections in feedlot animals vaccinated at the time of arrival. Calves vaccinated 72 or 96 hours before challenge had reduced clinical signs, lower body temperatures, lower vir...
متن کاملSusceptibility of bovine macrophages to infectious bovine rhinotracheitis virus infection.
Infectious bovine rhinotracheitis virus replicated in cultured bovine alveolar macrophages (AM). However, yields of infectious virus were low, with maximum titers approximately 100 times that of the residual inoculum. Immunofluorescence and electron microscopic studies indicated that the majority of macrophages produced viral antigen, but after infection at a multiplicity of 0.1, only 4.1% of A...
متن کاملTemperature-Sensitive Mutants of Measles Virus
were isolated after mutagenesis by 5-azacytidine, 5-fluorouracil, or proflavine. The restricted replication of all mutants at 39 C was blocked subsequent to cell penetration and could not be attributed to heat inactivation of virus infectivity. Complementation analysis was made possible through the use of poly-L-ornithine. The members of one complementation group exhibited wild-type RNA synthes...
متن کاملTemperature-Sensitive Mutants of Vesicular Stomatitis Virus
Different temperature-sensitive mutants of vesicular stomatitis virus have been characterized in terms of their ability to induce synthesis of viral ribonucleic acid (RNA) in BHK-21 cells at 39 C (the restrictive temperature for these mutants). Mutants belonging to complementation groups I and IV (and probably II) did not induce actinomycin-resistant RNA synthesis in infected cells incubated at...
