Characterization of enterotoxin producing Clostridium perfringens isolated from foods of animal origin [PDF]

, 2017
Screening of 105 samples comprising of milk, meat and their products for isolation of Clostridium perfringens revealed a total of 39 (37.14%) samples to be positive for C. perfringens, yielding an equal number of isolates.

The effects of probiotic Bacillus subtilis on the cytotoxicity of Clostridium perfringens type a in Caco-2 cell culture

BMC Microbiology, 2017
Background Some Bacillus strains have recently been identified for potential use as probiotics and food additives. The present study evaluated the antimicrobial effects of Bacillus subtilis ATCC 6633 and its metabolite on the enterotoxin and vegetative ...

Processing of Clostridium perfringens Enterotoxin by Intestinal Proteases

Toxins
C. perfringens type F isolates are a leading cause of food poisoning and antibiotic-associated diarrhea. Type F isolate virulence requires production of C. perfringens enterotoxin [CPE], which acts by forming large pore complexes in host cell plasma membranes. During GI disease, CPE is produced in the intestines when type F strains undergo sporulation.

Biological assay for Clostridium perfringens enterotoxin with vero cells.

The Japanese Journal of Veterinary Science, 1984
A simple and reproducible assay method using African green-monkey kidney (Vero) cells for Clostridium perfringens enterotoxin was developed. Vero cells were incubated with enterotoxin in wells on a microtiter plate for 60 min at 37 C and stained with a 0.2% nigrosin solution. A nearly linear curve was obtained between the ratio of the stained cells and

A study of Clostridium difficile in biofilm mode of growth using the Sorbarod filter system [PDF]

In all ecosystems, bacteria are likely to grow in biofilms, and the organisms making up the natural flora of the colon are considered to be no exception to this. One of the most important hospital-acquired infections is antibiotic associated diarrhoea,

Improved Media for Sporulation and Enterotoxin Production by Clostridium perfringens

Journal of Food Protection, 1986
Sporulation of 24 strains of Clostridium perfringens isolated from stools of food poisoning patients and normal controls was improved by adding sodium carbonate to Duncan-Strong (DS) sporulation medium and replacing starch with raffinose in Taniguti's AEA medium.
