Clostridium perfringens is a gram-positive, anaerobic bacterium that causes a wide range of diseases in humans and animals. Th e purposes of this study were to determine, using the enzyme-linked immunosorbent assay (ELISA), the clostridial toxins in intestinal samples of lambs with suspected enterotoxemia; to conduct molecular typing of C. perfringens isolates; and to investigate the presence o...

The effectiveness as antimicrobials of lactic acid bacteria produced compounds reuterin and nisin was assessed against vegetative cells and spores of Clostridium perfringens isolates (from ovine milk obtained in farms with diarrheic lambs) and C. perfringens CECT 486 (type A toxin producer). We also tested the inhibitory effect of lysozyme and sodium nitrite on Clostridium. Minimal inhibitory c...

The present investigation was conducted to study the effects of experimental Clostridium perfringens type D enterotoxaemia in teddy goats. Clinical signs started to appear after 30 min of experimental infection like anorexia, diarrhea, dehydration, frothing and dyspnea. Gross lesions consisted of severe congestion in tissues of varying intensity with enlarged mesenteric lymph nodes while histol...

Designing and producing a proper fusion construction is the most important problem of producing large quantities of a properly folded functional protein. This construction should have all necessary components of a real gene. A good designed fusion gene construction could be cloned into a good and suitable host. Clostridium perfringens is an important pathogen of humans and livestock and produce...

Clostridium perfringens is an important cause of enteric diseases in both human and animals. The bacteria produce several toxins which play key roles in the pathogenesis of diseases and are classified into five toxin types, on the basis of the differential production of Alpha, Beta, Epsilon and Iota toxins. In this study a single PCR assay was developed and used for detection of cpb2 gene to id...

In this research a molecular method based on polymerase chain reaction for typing of Clostridium perfringens was developed and toxin genotypes of 64 isolates from sheep and goats in Iran were determined. The PCR assays were developed for detection of alpha (cpa), beta (cpb) and epsilon (etx) toxin genes, allowing classification of the isolates into genotypes A B, C and D. The field isolates ...

background and objectives: clostridium perfringens, a gram-positive obligate anaerobic bacterium, is able to form resistant spores which are widely distributed in the environment. c. perfringens is subdivided into five types a to e based on its four major alpha, beta, epsilon and iota toxins. the aim of the present study was cloning and expression of c. perfringens type d vaccine strain epsilon...

Ostrich (Struthio camelus) chicks less than 3 mo age are observed to experience a high mortality rate that is often associated with enteritis. This study was undertaken to investigate the infectious bacteria implicated in ostrich chick enteritis. Postmortems were performed on 122 ostrich chicks aged from 1 d to 3 mo and intestinal samples were subjected to bacterial culture. Bacterial isolates ...
