Abstract The present study was carried out to investigate the outbreaks of chicken infectious anaemia virus (CIAV) infections in poultry of Chhattisgarh. A total of 250 birds were screened for CIAV PCR assay using CIAV specific primers produced an amplicon of approximately 713 bp indicating CIAV infection. The necropsy showed severe anemia indicated by paleness of carcasses. Grossly, CIAV affected birds showed paleness in liver and kidney and atrophic changes in bursa of Fabricious, thymus and spleen. Microscopically, CIAV-positive birds showed severe depletion of lymphocyte population from thymus, bursa of Fabricious and spleen, severe congestion and vacuolation in brain, degenerative and necrotic changes along with mononuclear cell infiltration in liver, haemorrhages in lungs and congestion, degeneration, necrosis and fibrous tissue proliferation in kidneys.
