title: Enterotoxin formation by Clostridium perfringens type A studied by the use of fluorescent antibody.
abstract: Fluorescein isothiocyanate-conjugated antibody to purified enterotoxin of Clostridium perfringens was used to study the intracellular formation of enterotoxin by this organism. Enterotoxin was detected at 4 h of growth at the end of the cell containing forespore. With the development of the spore, enterotoxin accumulation continued and involved the entire length of the cell until its lysis with the release of enterotoxin and mature spore. The spores did not contain demonstrable enterotoxin. Only a certain number of the sporulated cells of the enterotoxigenic strains studied produced this toxin. The amount of enterotoxin produced varied with sporulation percentage, and between strains and individual cells.
