The PCR method was used for the determination of LTI, STI, STII enterotoxins and Stx2e toxin genes in E. coli strains isolated from pigs with diarrhea. It was shown that most of the strains (77.3%) were enterotoxigenic, producing mainly LTI and STII (30.8%) or STI and STII (21.3%) toxins. It was found that 10.6% of isolates possessed the stx2e genes responsible for the elaboration of shiga toxin 2e.
