[Combinations of pathogenicity factors in Escherichia coli isolated from children and domestic animals].

The study has shown that in E. coli strains isolated from children aged up to 1 year with acute intestinal diseases of unknown etiology different combinations of pathogenicity factors (Ent. K88, K99, Vir, CFAI, CFAII, HIy, ColV, ColI) can be detected in 47.1 +/- 3.8% of cases, while in E. coli strains isolated from practically healthy children of the same age combined carriership of these factors does not exceed 5.8 +/- 2.5%. In E. coli strains isolated from swine and cattle with diarrhea the combined carriership of pathogenicity factors is 68.5 +/- 2.8% and 58.4 +/- 4.9% respectively.
