Chicken infectious anaemia is an immunosuppressive disease primarily of young chickens, but it also infects the chickens of all age groups. The loss due to CIAV infection are estimated to crores of rupees causing great economic hardship to the poultry farmers due to increased mortality, poor growth, poor feed conversion, reduced weight gain and increased condemnation rates at slaughter and the cost of antibiotics used to control secondary bacterial infections. Hence, the current scenario warrants the need for constant monitoring of this virus in the field for emergence of any new variants and consequent change in pathogenicity. Therefore, the need was felt to go for the detection and molecular characterization of CIAV circulating in the field, in order to emphasize the importance of CIAV in the state. This book, a part of M.V.Sc thesis submitted to the Tamilnadu Veterinary and Animal Sciences University, Chennai, India explores the characterization of the CIAV at genome level, serosurveillance of CIAV in different breeder flocks and commercial layer birds, detection of CIAV infection in commercial poultry farms, and assessing CIAV contamination in different live poultry vaccines
