| Summary |
An outbreak of anemia caused by chicken anemia virus (CAV) infection was diagnosed in a broiler flock in 1991 in Taiwan. The affected chicks had yellowish bone marrow and severe depletion oflymphocytes in the lymphoid organs were observed in most birds examined, Twelve CAV isolates were obtained in MDCC-MSBl cells from livers of the affected chicks. Anemia was induced in specific-pathogen-free chicks inoculated with an isolate at one day of age. In total 209 ( 71.58 % ) serum samples from nine breeder flocks of 292 serum samples from 11 breeder flocks had the antibody against CAV by an ind-irect immunofluorescent antibody test.
