clostridium perfringens is a part of the microflora of soil, and many reports have revealed the widespread occurrence of this organism in raw and processed foods. c. perfringens is classified into five types (types a to e), depending upon their ability to express alpha, beta, epsilon, and iota toxins in this study, a multiplex polymerase chain reaction (pcr) assay was developed for detection of...

Clostridium perfringens is an important pathogen that provokes numerous different diseases. This bacterium is classified into five various types, each of which capable of causing a distinct disease. There are various methods for the bacterial identification, many are labor-intensive, time-consuming, expensive and also show low sensitivity and specificity. The aim of this research was to identif...

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...

clostridium perfringens is an important cause of bacterial food poisoning worldwide. the disease is caused by c. perfringens enterotoxin (cpe) encoded by cpe gene. the aim of this research was to identify the different types of c. perfringens and the presence of cpe gene in isolated bacteria from broilers’ meat marketed in retail meat shops of mashhad city in northeastern of iran. after isolati...

the aim of this study was to determine the presence of toxin genes in clostridium perfringens isolated from 200minced meat samples using molecular typing. for this purpose, after isolation of clostridium perfringens using conventional culture method and confirmation by specific 16srd na gene pcr, alpha (cpa), beta (cpb), beta 2 (cpb2),epsilon (etx), iota (ia) and enterotoxin (cpe) genes were in...

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...

Clostridium perfringens is an important cause of bacterial food poisoning worldwide. The disease is caused by C. perfringens enterotoxin (CPE) encoded by cpe gene. The aim of this research was to identify the different types of C. perfringens and the presence of cpe gene in isolated bacteria from broilers’ meat marketed in retail meat shops of Mashha...

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...

background : clostridium perfringens type c strains cause severe necrotizing enteritis in sheep, calves, goats, pigs and humans. beta-toxin is introduced to be the essential virulence factor of this microorganism. in the present study, a new method was established for the purification of beta toxin from culture supernatant fluid of c. perfringens type c vaccinal strain. methods : the four steps...
