Nephropathogenic Infectious Bronchitis (NIB) is an important viral disease of poultry associated with severe renal damage and economic losses. The present study investigated the haematological alterations associated with naturally occurring NIB in broiler chickens from five confirmed flocks. Gross and histopathological examination revealed visceral uricosis, renal congestion, haemorrhage, necrosis, interstitial nephritis, glomerulonephritis, tubular degeneration and necrosis, and urate crystal deposition. Haematological analysis showed significantly reduced (P<0.05) haemoglobin (Hb), total erythrocyte count (TEC), and total leukocyte count (TLC), indicating anaemia and leukopenia. Differential leukocyte count revealed significant heterophilia, lymphopenia, and reduced monocyte percentage, whereas eosinophil and basophil percentages did not differ significantly. These findings indicate that NIB is associated with characteristic haematological alterations that may serve as supportive indicators of disease in naturally infected broiler flocks.
