The overall positive samples were 57 out of examined 120 chickens with incidence of 47.5 %. Regarding chicken breed, isolation rate in autumn were 65% and 60.0%, in winter 35.0% and 20.0% in spring 25.0% and 40.0%, in summer 85.0% and 30.0% was recorded out of broilers and layers; respectively. perfringens isolates were serologically typed into 24 type A, 3 type C and 30 nontoxigenic isolates. Type A isolates Were 5,2, 6 and 11 in autumn, winter, spring and summer; respectively. While type C isolates were 2 in autumn and 1 in spring.
