Prevalence of cpb2, encoding beta2 toxin, in Clostridium perfringens field isolates: correlation of genotype with phenotype.
Beta2 toxin, encoded by the cpb2 gene, has been implicated in the pathogenesis of porcine, equine and bovine enteritis by type A Clostridium perfringens. By incorporating primers to cpb2 into a… Expand

Atypical cpb2 Genes, Encoding Beta2-Toxin in Clostridium perfringens Isolates of Nonporcine Origin
ABSTRACT Beta2-toxin, encoded by cpb2, is implicated in the pathogenesis of Clostridium perfringens enteritis. However, cpb2 genes from nonporcine C. perfringens isolates were not always expressed,… Expand

Clostridium perfringens Beta-Toxin Forms Potential-Dependent, Cation-Selective Channels in Lipid Bilayers
ABSTRACT Recombinant beta-toxin from Clostridium perfringenstype C was found to increase the conductance of bilayer lipid membranes (BLMs) by inducing channel activity. The channels exhibited a… Expand

An Arcanobacterium (Actinomyces) pyogenes mutant deficient in production of the pore-forming cytolysin pyolysin has reduced virulence.
Pyolysin (PLO), the hemolytic exotoxin expressed by Arcanobacterium (Actinomyces) pyogenes, is a member of the thiol-activated cytolysin family of bacterial toxins. Insertional inactivation of the… Expand
