Outbreak of Clostridium perfringens type D enterotoxemia in sheep

Prevalence of Clostridium perfringens toxin genotypes in enterotoxemia suspected sheep flocks of Andhra Pradesh

Aim: To identify the Clostridium perfringens toxin genotypes prevailing in enterotoxemia suspected sheep flocks in Andhra Pradesh by using multiplex PCR. Materials and Methods: Intestinal scrapings were collected from lambs below three months of age from flocks with similar management from different Districts of Andhra Pradesh, in India. A total of 208 samples were collected with 140 from enter...

Prevalence and Toxinotyping of the Toxigenic Clostridium perfringens in Sheep with suspected Enterotoxemia

The study was designed to determine the types of Clostridium perfringens and their toxins in sheep with suspected enterotoxemia in AlAhsa province, KSA. Out of 240 intestinal content samples collected from dead sheep with suspected enterotoxemia, 34 Clostridial strains were isolated. Diagnosis was based on classical diagnostic tests, enzyme-linked immunosorbent assay (ELISA) and multiplex polym...

Preparation of Standard Clostridium perfringens Antitoxin in the Sheep

Hepatic and renal ultrastructural lesions in experimental Clostridium perfringens type A enterotoxemia in chickens.

Hepatic and renal electron microscopic investigations were carried out in 10 chickens that had experimental intraduodenal infection with Clostridium perfringens Type A. Fourteen days postinfection, there were ultrastructural changes in hepatocytes and renal tubular epithelial cells; these included mitochondrial lesions (swelling, cristolysis, rarefication of the matrix, myelin figures), glycoge...

Haemorhagic enterotoxemia by Clostridium perfringens type C and type A in silver foxes.

Type C and type A of C. perfringens were detected in the seat of natural infections in silver foxes characterized by symptoms of haemorrhagic enterotoxemia. In all of the dead foxes characteristic changes were noted in the small intestine and parenchymatous organs. The production of alpha and beta toxins by isolated bacteria was confirmed by the bioassay using white mice and by PCR. The results...
