Toxin typing of Clostridium perfringens Associated with Enterotoxaemia in Sheep in Fars Province [PDF]

Archives of Razi Institute, 2021
Clostridium perfringens is implicated in the etiology of some diseases including fatal enterotoxaemia. Determining dominant toxin types of this microorganism can be helpful in epidemiologic surveys and the formulation of more proper vaccines.

Epsilon-Toxin Plasmids of Clostridium perfringens Type D Are Conjugative [PDF]

Journal of Bacteriology, 2007
ABSTRACT Isolates of Clostridium perfringens type D produce the potent epsilon-toxin (a CDC/U.S. Department of Agriculture overlap class B select agent) and are responsible for several economically significant enterotoxemias of domestic livestock.

Determination of Type and Molecular Identity of Clostridium perfringens Isolated from Patients with Multiple Sclerosis (MS) [PDF]

Journal of Advanced Biomedical Sciences, 2022
Background & Objectives: Multiple sclerosis (MS) is a chronic inflammatory autoimmune disease of the central nervous system (CNS). Clostridium perfringens ε-toxin (ETX) can cause emerging complications of MS due to its tendency to the blood-brain barrier.

Virulence Plasmid Diversity inClostridium perfringensType D Isolates [PDF]

Infection and Immunity, 2007
ABSTRACTClostridium perfringenstype D isolates are important in biodefense and also cause natural enterotoxemias in sheep, goats, and occasionally cattle. In these isolates, the gene (etx) encoding ε-toxin is thought to reside on poorly characterized large plasmids.

The Pathology of Peracute Experimental Clostridium Perfringens Type D Enterotoxemia in Sheep [PDF]

Journal of Veterinary Diagnostic Investigation, 2004
The pathological findings in sheep with peracute experimental Clostridium perfringens type D enterotoxemia are described. Of 16 animals inoculated intraduodenally with a whole culture of this microorganism and a starch solution in the abomasum, 12 developed clinical signs including increased respiratory efforts, recumbency, paddling, bleating ...

Clostridium perfringensepsilon toxin H149A mutant as a platform for receptor binding studies [PDF]

, 2013
Clostridium perfringens epsilon toxin (Etx) is a pore-forming toxin responsible for a severe and rapidly fatal enterotoxemia of ruminants. The toxin is classified as a category B bioterrorism agent by the U.S.

Genotyping of Clostridium perfringens associated with sudden death in cattle

Journal of Venomous Animals and Toxins including Tropical Diseases, 2009
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.
