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...

Clostridium perfringens (C. perfringens) is an important pathogen in both human and veterinary medicine. Necrotic enteritis is the most severe clinical bacterial enteric disease of poultry induced by C. perfringens. Study was done on 100 broiler chickens (400 different tissues of chickens) in Southwest Iran. C. perfringens was isolated from different tissues of chickens (meats, liver, gizzard a...

Antagonistic effect of piglet microflora against Clostridium perfringens was studied in germfree mice, to isolate bacterial strains responsible for this colonization resistance. The 1:100 dilution of the feces of a 2 day-old conventional piglet, given per os to germfree mice already harboring C. perfringens, led to the elimination of C. perfringens. From this piglet flora, 8 bacterial strains w...

A 21-year-old Japanese man with a history of marked body weight loss over a short period of time died of necrotizing duodenitis caused by Clostridium perfringens (C. perfringens) type A. C. perfringens type A is considered to usually cause self-limiting gastroenteritis. Necrotizing enteritis sometimes occurs due to C. perfringens in developing countries; however, it is primarily caused by the t...

This study evaluated the risk of Clostridium perfringens (C. perfringens) foodborne illness from natural and processed cheeses. Microbial risk assessment in this study was conducted according to four steps: hazard identification, hazard characterization, exposure assessment, and risk characterization. The hazard identification of C. perfringens on cheese was identified through literature, and d...

background and objectives: clostridium perfringens is more prevalent type of clostridia genus isolated from the intestinal tract of ostrich ( struthio camelus ). necrotic enteritis (ne) is a potentially fatal gastrointestinal (gi) disease of poultry and other avian species, which produces marked destruction of intestinal lining in digestive tract caused by c. perfringens . pathogenicity and les...

Clostridium perfringens is a common inhabitant of the avian and mammalian gastrointestinal tracts and can behave commensally or pathogenically. Some enteric diseases caused by type A C. perfringens, including bovine clostridial abomasitis, remain poorly understood. To investigate the potential basis of virulence in strains causing this disease, we sequenced the genome of a type A C. perfringens...

Nine Clostridium perfringens strains were isolated from fifteen intestinal content samples collected from commercial broilers which suffered from necrotic enteritis NE. Molecular typing of C. perfringens was performed by PCR using three sets of primers specific for toxin -producing genes of C. perfringens [alpha (900bp), beta (236bp) and epsilon (541bp)]. Six strains of C. perfringens type A an...

BACKGROUND Although Clostridium perfringens (C. perfringens) is well known as the causative agent of several forms of enteric disease, precise epidemiological and pathobiological aspects are still unknown. METHODS We retrospectively reviewed the culture results of samples collected in our hospital from 2001 through 2013. In addition, for the detection and toxinogenic typing of C. perfringens,...

A stable shuttle vector which replicates in Escherichia coli and Clostridium perfringens was constructed by ligating a 3.6-kilobase (kb) fragment of plasmid pBR322 with C. perfringens plasmid pHB101 (3.1 kb). The marker for this shuttle plasmid originated from the 1.3-kb chloramphenicol resistance gene of plasmid pHR106. The resulting shuttle vector, designated pAK201, is 8 kb in size and codes...
