Hepatic and renal ultrastructural lesions in experimental Clostridium perfringens type A enterotoxemia in chickens.
Hepatic and renal electron microscopic investigations were carried out in 10 chickens that had experimental intraduodenal infection with Clostridium perfringens Type A. Fourteen days postinfection, there were ultrastructural changes in hepatocytes and renal tubular epithelial cells; these included mitochondrial lesions (swelling, cristolysis, rarefication of the matrix, myelin figures), glycogen loss, and capillary endothelial cell swelling in both organs, as well as thickening of glomerular basement membrane. The findings are discussed with particular reference to the pathogenesis of Clostridium perfringens Type A enterotoxemia.
