Rapid detection of Clostridium perfringens type A enterotoxin by enzyme-linked immunosorbent assay
Abstract
Clostridium perfringens type A enterotoxin was specifically detected and readily quantified by indirect and four-layer sandwich enzyme-linked immunosorbent assays (ELISAs). With the indirect ELISA, enterotoxin was detected in quantities of as low as 2.5 ng (25 ng/ml). When the more sensitive sandwich ELISA procedures was used, 100 pg (1 ng/ml) of enterotoxin was detected. The sandwich ELISA procedure specifically detected enterotoxin in human fecal extracts. Additionally, the sandwich ELISA specifically differentiated enterotoxin-positive strains from enterotoxin-negative strains of C. perfringens. Both the indirect and sandwich ELISA procedures described for C. perfringens enterotoxin in this report are rapid, specific, sensitive, and easily adaptable for large-scale use by clinical or research laboratories.
