Pathological and clinical investigations of an outbreak of Blackleg disease due to C. chauvoei in cattle in Punjab, Pakistan

Abstract: Introduction: Clostridium chauvoei (C. chauvoei) is an anaerobic, histotoxic Gram-positive, bacterium causing fatal myonecrosis in livestock with high mortalities. The disease is common in dairy animals, but little is known about the pathophysiology of the disease in exotic (non-native) animals kept under local conditions in Pakistan. Methodology: Diagnosis of blackleg was made based on hematological and serum biochemical analysis, PCR, necropsy and histopathology. Results: Clinically sick animals … Show more

“…In the acute form, the body temperature of the animal increases to 41–42°C; the animal shows signs of depression, including a refusal to eat and lethargy; and subcutaneous gas oedema forms, especially in the extremities, with swelling and crepitus in the affected muscles ( 21 , 22 ). In the hyper-acute form, the clinical signs are usually not observed due to the sudden death of the affected animal ( 5 ).…”

“…The characteristic pathological and anatomical changes are acute necrohemorrhagic emphysematous myositis of the skeletal muscles, most often of the thoracic and pelvic belt muscles 5,17,18 ; expressed pulmonary oedema; myocarditis and petechial haemorrhages on the heart; liver enlargement; and venous hyperaemia of the liver and spleen 17,22,23 . Visceral myonecrosis is less commonly noted and may affect the heart, hyoid muscles and diaphragm 24,18 .…”
