Studies on Pathogenicity of Chicken Infectious Anaemia Virus Isolated From a Poultry Flock of Chhattisgarh, India
Abstract:
The present study reports the effects of a recent isolate of chicken infectious anaemia virus (CIAV) designated as Durg CIAV, recovered from a poultry flock of Raipur, Chhattisgarh state, India. In experimentally infected day old chicks, the isolate produced consistent clinical signs, low haematocrit values and generalized lymphoid atrophy particularly of thymus, bursa and spleen along with depletion of lymphocytes from the lymphoid organs in almost all infected chicks. Haematological studies revealed significant decrease in haemoglobin (p≤0.01), PCV (p≤0.01), total leucocyte count (p≤0.01) and lymphocyte (p≤0.05) values. Results revealed that Durg CIAV isolate is pathogenic and immunosuppressive in nature. Therefore, suitable prevention and control strategies need to be formulated to prevent the virus infection in avian flocks in the country.
