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...

باکتری clostridium perfringens (c. perfringens) یک باسیل گرم مثبتِ بی هوازی هاگ دار و بیماری زا است که در طبیعت، و سیستم گوارش و برخی دیگر از اندام های بدن انسان و دام، به وفور یافت می شود. توکسین های اپسیلون و بتا از توکسین های اصلی c. perfringens تیپ هایd وb هستند که از فاکتورهای ویرولانس در این تیپ ها بوده و عامل ایجاد بیماری های انتریت نکروزی، انتروتوکسمی و قلوه نرمی در گوسفند، بز و بندرت در...
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...
In a study to identify the clostridial species associated with sporadic diarrhoea in children aged 5 years and below, clostridia species were isolated from 57 (3%) of 1761 diarrhoeic faecal samples studied. Fifty-one of the clostridial isolates were identified as Clostridium perfringens while the other six isolates were identified as C. bifermentans. Forthy-seven were C. perfringens type A, 4 w...
Introduction & Purpose Fecal coliforms and Escherichia coli have been conventionally used as indicators of microbial pollution of drinking water. The European Directive on drinking water quality has included Clostridium perfringens as one of the microbiological parameters to be determined in control of the water quality for human consumption. This study was carried out to evaluate the efficien...

The epidemiological and bacteriological investigations on four foodborne outbreaks caused by a new type of enterotoxin-producing Clostridium perfringens are described. C. perfringens isolated from patients of these outbreaks did not produce any known enterotoxin and did not carry the C. perfringens enterotoxin gene. However, the culture filtrates of these isolates induced the accumulation of fl...
A hydrophobic grid membrane filter-colony hybridization (HGMF-CH) method for the enumeration and isolation of cpe gene-carrying (cpe-positive) Clostridium perfringens spores from feces was developed. A 425-bp DNA probe specific for the cpe gene was sensitive and specific when tested with bacterial DNA and pure cultures. The enumeration of cpe-positive C. perfringens by the HGMF-CH method proved...
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...
