Abstract
In this study, C. perfringens isolated from liver and intestine of diseased chickens (50% and 100%, respectively) and isolated from liver and intestine of diseased ducks (50% and 80%, respectively) as well as from liver and intestine samples of diseased turkey (40% and 80%, respectively). The diseased turkeys voided C. perfringens in 28 out of 45 samples (62.2%) while the percentage was 42.2% among the apparently healthy turkey samples. The majority of isolates collected from chickens were belonged to toxin type A with incidence of 35.6% followed by type D (15.6%). The majority of isolates from turkeys belonged to toxin type A with an incidence of 34% followed by type D (19.1%) then type C (10.6%). The majority of isolates from ducks belonged type A (31.1%) followed by type C (17.8%). Trial was made in this study to describe the C. perfringens toxins by SDS-PAGE.
