Faecal shedding of verotoxigenic Escherichia coli in cattle in the Czech Republic

Popis výsledku v původním jazyce

Prevalence of verotoxigenic E. coli (VTEC) in rectal swabs from healthy dairy cattle was estimated in three herds in the Czech Republic. Presence of the stx1, stx2 and eaeA genes in faecal swab cultures was detected by PCR. VTEC were detected in animalsfrom all three herds. In the group of 3-week-old calves, VTEC were only detected in samples collected in the summer months. However, in the other age-groups, VTEC were detected in both the summer and winter months. EHEC shedding was observed in 30 to 100% of the total samples collected from cattle aged three months and one year in the summer months, and in 30 to 60% of samples taken in the winter months. EHEC strains of serogroup O157 were detected in two herds. The range of verotoxins shed by VTEC isolates of serogroup O157 differed between herds. Besides serogroup O157, additional EHEC belonging to the antigen groups O26, O103, O128 and O153 have been identified, and in some of them, no somatic antigen was detected.
