Enzyme-linked immunosorbent assay for rapid detection of toxins from Clostridium perfringens.
An enzyme-linked immunosorbent assay (ELISA) with antibodies specific to beta, epsilon and iota ib toxins of Clostridium perfringens was developed to detect beta, epsilon and iota ib toxins, respectively. The ELISA was sensitive enough to detect as little as 1.0 ng/ml of purified beta and iota ib toxins and 0.1 ng/ml of purified epsilon toxin. By means of the ELISA method, 192 isolates of C. perfringens from food samples in Japan and Thailand, and 58 isolates from patients suffering from gas gangrene or gastroenteritis were examined. One isolate from food samples in Japan, three from food samples in Thailand and five from stools of patients with gastroenteritis were C. perfringens type D. One type B and one type C were detected from the stools of patients with gastroenteritis.
