Title: Experimental Diarrhoea in Human Volunteers Following Oral Administration of <i>Clostridium perfringens</i> Enterotoxin
Abstract: Peroral administration of purified enterotoxin to human volunteers provoked diarrhoea and abdominal pain, symptoms identical with those encountered in outbreaks of Clostridium perfringens food poisoning. Eight milligrams of enterotoxin caused diarrhoea in one of two volunteers. All of five subjects given 10 and 12 mg of purified enterotoxin or crude enterotoxin developed the classical symptoms of this food poisoning. Passive haemagglutination anti‐enterotoxin titres in serum increased in only 5 of 9 volunteers after exposure to enterotoxin. As such levels of anti‐enterotoxin can be detected in normal serum samples, titration of anti‐enterotoxin may be of little use in diagnosing Cl. perfringens food poisoning. Enterotoxin was detected in all diarrhoeal faecal specimens, and the enterotoxin level varied from 0·2–16 μg/g. Detection of enterotoxin in diarrhoeal faeces may be the most reliable procedure in diagnosing outbreaks of Cl. perfringens food poisoning.
