Chicken infectious anaemia is one immunosuppressive agent that chicken was considered to be the natural host of chicken anaemia virus (CAV). For detection of this virus in commercial Japanese quail flocks, 250 thymus samples were taken from 50 quail flocks in Isfahan and Yazd provinces, Iran. Thymus samples were taken by history recording and direct observation of quail carcasses in quail flocks with mortality. Viral DNA was extracted by DNA extraction kit and amplified a fragment of VP2 gene. The results showed the prevalence of CAV infection in 50 quail flocks was 22%. This study revealed quail can be as a host of CAV and it is necessary to take controlling strategy for preventing of CAV infection between chicken and quail flocks.
