ABSTRACT
Out of 4,082 Escherichia strains isolated from 989 hospitalized patients with acute enteric infections 2,979 strains belonged to 139 O-groups and the remaining strains could not by typed with O-sera (O1-O164) or were in the serological R-form. 19.3% of the strains isolated from 354 patients showed a positive reaction for thermolabile enterotoxin (TLET) determined in the radioimmunoassay. Escherichia with pronounced reaction for TLET were isolated from 5.5% of the patients. The serological picture of Escherichia with a positive reaction for TLET comprised 78 O-groups, showed practically no variations in children of different age and adult patients and was related to the intensity of reaction for TLET. The number of enterotoxigenic Escherichia greatly varied within individual O-groups from 3.1 +/- 3.63% (O11) to 100 +/- 9.81% (O114) of the total number of known strains in these O-groups. In most O-groups the number of enterotoxigenic strains varied from 10% to 50%. The most widely spread serovars of etiologically important enterotoxigenic Escherichia belonged to 24 O-groups and were often isolated as monocultures. The capacity for producing TLET (and, probably, some other antigenically related substances) in widely spread among Escherichia; still, the determination of enterotoxicity is a necessary, but not sufficient criterion of their etiological importance in acute enteric infections.
