The current study was conducted to detect fibrinous pericarditis and perihepatitis in naturally infected broilers and layers chickens in Basrah province, Iraq, on the basis of clinicopathological findings, and blood alterations. Suspected samples were obtained from several locations in Basrah province (Al-Hartha, Abo Alkaseb, and Al-Qurnah). The result of this study showed some birds presented clinical symptoms like the chicken reduced feed efficiency, weight loss, ruffled feathers, labored rapid breathing, coughing, and reduced consciousness. The blood tests revealed a significant increase (P≤0.05) in WBCs, heterophils, and lymphocytes. The results of biochemical revealed a significant increase (P≤0.05) in (ALT and AST and troponin titer) compared with healthy birds. The macroscopical of the internal organs showed severe accumulation of white typical fibrinous exudate in the pericardial sac. In addition, there is an enlargement of the liver with obvious of white typical fibrinous exudate in the parietal surface of the liver. The histopathological section of the heart showed severe infiltration of inflammatory cells in the pericardial sac with fibrinous exudation. There is an edematous exudate in the myocardial muscle fibers. The histopathological section of the liver showed thick severe fibrinous exudate capsulated on the liver surface. The histochemical section of the heart and the liver showed bluish-positive staining of collagen and fibrin fibers that accumulate in the pericardial sac and in the hepatic capsular. The study concluded that fibrinous pericarditis and perihepatitis lead to an effect on the health status and performance of different species of chickens as a broiler or layer.
