Mechanisms of Action and Cell Death Associated with Clostridium perfringens Toxins

Clostridium perfringens and its arsenal of toxins.

GENOTYPING OF Clostridium perfringens ASSOCIATED WITH SUDDEN DEATH IN CATTLE

Toxigenic types of Clostridium perfringens are significant causative agents of enteric disease in domestic animals, although type E is presumably rare, appearing as an uncommon cause of enterotoxemia of lambs, calves and rabbits. We report herein the typing of 23 C. perfringens strains, by the polymerase chain reaction (PCR) technique, isolated from small intestine samples of bovines that have ...

Clostridium Perfringens Toxin Types Associated with Meat: Review in Iran

Food poisoning due to Clostridium perfringens (C. perfringens) is a major food health problem, particularly in terms of meat consumption. Due to human’s susceptibility to this pathogen, detection methods and prevention measures should be implemented to reduce its incidence. Several pathogenic strains of C. perfringens have been identified so far. One of the potential concerns about this bacteri...

Clostridium Perfringens Toxins Involved in Mammalian Veterinary Diseases

Clostridium perfringens is a gram-positive anaerobic rod that is classified into 5 toxinotypes (A, B, C, D, and E) according to the production of 4 major toxins, namely alpha (CPA), beta (CPB), epsilon (ETX) and iota (ITX). However, this microorganism can produce up to 16 toxins in various combinations, including lethal toxins such as perfringolysin O (PFO), enterotoxin (CPE), and beta2 toxin (...

Mechanisms of Antibacterial Action of Quinoxaline 1,4-di-N-oxides against Clostridium perfringens and Brachyspira hyodysenteriae

Quinoxaline 1,4-di-N-oxides (QdNOs) are a class of bioreductive compounds, however, their antibacterial mechanisms are still unclarified. The aim of this study was to assess the ability of two representative QdNO drugs, cyadox (CYA) and olaquindox (OLA), to produce reactive oxide species (ROS) in Gram-positive anaerobe Clostridium perfringens CVCC1125 and Gram-negative anaerobe Brachyspira hyod...
