The authors performen the bacteriological and epidemiological observations on the food poisoning incidence in October, 1966, which was caused by a strain of E. coli.<br>Epidemiological observations revealed that the number of patients, with principal symptoms of stomachache, nausea, vomitting, diarrhea and fever, 15 with 18.5% of morbidity. the patients were all adult and the mean time of incubation period was 10.5h.<br>E. coli strains were isolated almost in pure culture on the media used diagnostically from 5 patients examined. These cultures originated as single lactose-fermenting colonies on the media, which were there-after subcultured and identified by fermentative and biochemical reactions as Escherichia coli. These cultures were also identified by biological and serological reactions as E. coil O-111, B4 and agreed with the biological properties of type 1 described by F. Kauffmann. Widal reaction did not show any rise in O- antibody against the strain E. coil O-111, B4 which was isolated from the patients.
