Abstract

Three strains of chicken anemia virus (CAV) were detected in 11 to 14-weeks old chickens, showing depression, wasting, and increased mortality, from three farms in eastern Japan. Another strain was detected in 12-weeks old chickens from one farm without clinical signs. Bacterial infections were suggested in three farms with clinical signs and its involvement in the occurrence of the diseases might be suspected. Sequence analysis of the VP1, VP2, and VP3 genes of four CAV strains revealed that the three from farms with clinical signs belonged to genotype A2, whereas that from the apparently-normal farm belonged to A3. This may be a rare case report about the diseases suspected of the involvement of the CAV infection in older birds.
