Severe heart muscle degeneration caused by Clostridium perfringens type A in camel calves (Camelus dromedarius)

Clostridium perfringens type A was isolated from different organs and intestines from three to five weeks old camel calves which have died from heart muscle necrosis. No other bacterial pathogens were isolated. Virus isolation on two different cell lines including a fetal camel skin were also negative. Mice which were injected with bacteria free filtrates prepared from intestinal contents of necropsied camel calves died after one to six hours demonstrating the presence of clostridial toxins. Our findings suggest that the cardiac muscle necrosis is caused by Clostridium perfringens type A toxins.
