[Isolation and detection of avian adenoviruses on cell cultures].

It is important, from the hygienic and epizootological view-point, to detect the presence of various microbiological agents in birds. The authors present the results of the virological examination of poultry, avian adenoviruses being the main object of investigation. Ninety-eight virus strains were isolated from chickens of different age categories and were included in the group of avian adenoviruses according to the form of cytopathic changes on the cell cultures of hen kidneys, according to the need for adaptation passages, chloroform, thermal, and pH resistance, character of nucleic acid, formation of intranuclear inclusions, and joint precipitation antigen, shared with the reference virus.
