Necrotic enteritis in chicken is caused by the Clostridium perfringens, which have been found on almost chickensand for decades antimicrobial therapy was only strategy to control it. However misuse of antimicrobials linked many impacts like reduced susceptibility C. perfringens strains and cause cross-resistance agents. Thisworkdemonstrates that, uses herbal extracts with antibacterial effectsc...
Necrotic enteritis (NE) is one of the most important enteric diseases in poultry and is a high cost to the industry worldwide. It is caused by avian-specific, Necrotic Enteritis Beta toxin (NetB)-producing, strains of Clostridium perfringens that also possess in common other virulence-associated genes. In Europe the disease incidence has increased since the ban on in-feed "growth promoting" ant...
NetB, a New Toxin That Is Associated with Avian Necrotic Enteritis Caused by Clostridium perfringens
For over 30 years a phospholipase C enzyme called alpha-toxin was thought to be the key virulence factor in necrotic enteritis caused by Clostridium perfringens. However, using a gene knockout mutant we have recently shown that alpha-toxin is not essential for pathogenesis. We have now discovered a key virulence determinant. A novel toxin (NetB) was identified in a C. perfringens strain isolate...
NetB, a New Toxin That Is Associated with Avian Necrotic Enteritis Caused by Clostridium perfringens
Clostridium perfringens β-toxin (CPB) is a β-barrel pore-forming toxin and an essential virulence factor of C. perfringens type C strains, which cause fatal hemorrhagic enteritis in animals and humans. We have previously shown that CPB is bound to endothelial cells within the intestine of affected pigs and humans, and that CPB is highly toxic to primary porcine endothelial cells (pEC) in vitro....
