The authors demonstrated the etiological role of E. coli 06 in group acute intestinal diseases with the clinical picture of food poisoning. The leading role of the food factor in the spread of this infection was established. A study was made of 64 E. coli 06 cultures isolated from the patients in group infection and from the carriers examined by various indications. The cultures produced no keratoconjunctivitis in guinea pigs. The capacity to produce enterotoxin was revealed in 2 of 5 cultures tested in experiments with the intranasal infection of albino mice.
