A 48 kilodalton enterotoxin-related protein from Clostridium perfringens vegetative and sporulating cells.
Sporulating and vegetative cell extracts of enterotoxin-positive and enterotoxin-negative strains of Clostridium perfringens were examined by Western blotting using enterotoxin antiserum. A 48-kDa enterotoxin-related protein was found in vegetative and sporulating cell extracts of both toxin types. The results question previous reports about the ability of vegetative cells and presumptive enterotoxin-negative strains of this organism to produce enterotoxin, a protein with a molecular weight of 34 kDa.
