Indirect haemagglutination test for the detection of thermolabile (LT) enterotoxin from Escherichia coli

An indirect haemagglutination test (IH) for the detection of enterotoxigenic E. coli (LT) was developed. Twenty-five enterotoxigenic E. coli (ETEC) from human and porcine diarrhoea and from river water were examined. The described IH test was more specific and sensitive than the passive immune haemolysis test (PIH).
