Abstract

A total of 82 C. perfringensisolates (41%) were recovered from 200 samples collected from 100 turkeys (20 apparently healthy, 40 clinically diseased and 40 freshly dead), 4-6 weeks old. The clinical signs of diseased birds were sudden mortality, depression, ruffled feathers, diarrhea, dehydration, emaciation and decrease in feed consumption with increase in water consumption. While, postmortem findings were consistent with necrotic enteritis (NE), the small intestine was severely affected. Small and demarcated lesions were found in the duodenal loop, hepatitis and cholecystitis were also observed. Unopened intestines were gas-filled and enlarged with thin wall. The intestinal contents were dark due to necrotic material. The opened intestines showed necrotic lesions of varying severity of the mucosa. Isolation and biochemical identification of C.perfringenswere done.Five C.Perfringens field isolates were analyzed by PCR assay to determine the presence of some toxin genes.In all tested isolates, the Cpa gene (alpha toxin) was detected (100%) confirming the isolates were C.perfringens. While, Cpb (beta toxin) gene was detected in two samples (40%). But the Etx gene (epsilon toxin) was not detected in any isolate (0%). NetB gene was detected in two isolates (40%). Antimicrobial susceptibility of 40 C.perfringens field isolates recovered from turkeys revealed that C.perfringens isolates were sensitive to Ampicillin (85%), Amoxicillin (85%), Penicillin (82.5%), Florfenicol (72.5%), Enrofloxacin (67.5%), Vancomycin (65%), Bacitracin (60%), Oxytetracyclin (32.5%), Lincomycin (22.5%) and Clindamycin  (15%).These five C. perfringens isolates were also screened by PCR which detected the presence of tetracycline resistance gene tet(K) in three isolates (60%)  and Lincomycin resistance gene lin(B) in three isolates (60%).
