Abstract

Chicken infectious anemia virus (CIAV) is one of the most important immunosuppressive in chickens. Circoviruses are non-enveloped and icosahedral viruses. Their genomes are circular, single-stranded DNA. The CAV is recently re-classified as the only member of the genus Gyrovirus. The severity of clinical disease depends on several factors, including virus dose, age at infection. It is believed that the development of age resistance is strongly associated with the maturation of immune system. The aim of this study was to detect CIAV infection in broiler chickens of Khuzestan province, Southwestern of Iran. Samples from 50 broiler chicken at slaughterhouse were collected randomly 10 liver tissues. Results showed 32 (64%) of 50 broiler chicken were positive with PCR. Thirteen of 24 farms (54.16%) in broiler chickens were positive by ELISA test. It was concluded that CAVs infection widespread in broiler flocks of this area and proved high rate subclinical form of CIAV in broiler poultry farms.
