ISOLATION OF PORCINE ADENOVIRUS AS A CANDIDATE OF 5TH SEROTYPE

A strain of cytopathic virus, named strain TG/K79, was isolated from t he brain of a newborn piglet, pure Hampshire breed, which died shortly after birth. The physicochemical property of virus was considered to be that of the family Adenoviridae. A significant difference between o ur isolate and 4 reference porcine adenoviruses was demonstrated by cr oss-seroneutralization test. Differences between TG/K79 and other porc ine adenoviruses were also seen in electrophoretic patterns of viral D NA in agarose gel after digested by restiction endonucleases. Two SPF pigs, 2-month-old, experimentally infected via intranasal showed a fev er and a hemorrhagic enteritis. A serological survey indicates that at least swine in the farm where the virus was isolated have been highly contaminated.
