The in vivo distribution of bovine herpesvirus type 4 (BHV-4) was examined by testing nasal and conjunctival exudates, peripheral blood leukocytes, and various organs of experimentally infected calves. For virus detection, a nested PCR assay, virus isolation, and immunohistochemistry were applied. The nervous system and the muscles were free of viral DNA.(More)
Eight reference strains of the nine accepted bovine adenovirus serotypes were compared by means of restriction enzyme (RE) analysis of the viral DNA. The study was carried out with the aim to identify RE giving restriction patterns which are particularly feasible for identification of new isolates and useful for their classification into subgroups. The(More)
A slowly growing subgroup 2 bovine adenovirus (BAV) strain designated Ruakura 78-5371 was isolated from a yearling heifer with systemic adenovirus infection. Cross neutralization tests and restriction endonuclease analysis of the viral DNA showed the virus to be distinct from the other 9 recognised types of BAV. It is proposed that this strain should be(More)
The pathology of bovine herpesvirus type 4 (BHV-4) infection was studied in cats, rabbits and guinea pigs. Twenty kittens, twenty-two rabbits and ten guinea pigs, some treated with glucocorticoid-were inoculated with a BHV-4 strain of feline origin, via various routes of inoculation (conjunctival, intranasal, peritoneal). Clinical signs were recorded. After(More)
The DNA of thirty-three Hungarian bovine herpesvirus isolates originating from cattle with various clinical symptoms were compared by restriction endonuclease analysis using HindIII, EcoRI and BstEII enzymes. The EcoRI and HindIII cleavage patterns were similar to those of isolates studied in other countries. Based on the cleavage patterns, the Hungarian(More)
The DNA of a bovine herpesvirus 1 (BHV-1) strain isolated from calf encephalitis in Hungary was analysed with restriction enzymes. The cleavage pattern of the encephalitis strain Na/67 differed from those of all the other Hungarian BHV-1 isolates investigated so far. The EcoRI and HindIII cleavage patterns of virus strain Na/67 were found to be similar to(More)
