Abstract
Examined field chickens with signs and lesions of natural infection with necrotic enteritis (NE) revealed the isolation of Clostridium perfringens (C. perfringens) from positive chickens at the rate of 63.33%,30%, 30% and 66.66% in autumn, winter ,spring and summer; respectively. 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. C. perfringens Type A recovered from broiler and layer were 2 and 3, 2 and 0, 4 and 2, 10 andi in autumn, winter, spring and summer; respectively. Only 2 isolates of type C were recovered in autumn and 1 in spring.
