Of a total of 987 samples examind, 22 strains (2.2%) were identified as E. coli O157 and 10 of them as E. coli O157:H7. The virulence factors (stx1, stx2, eae and ehxA genes) were identified by polymerase chain reaction (PCR). Sensitivity to the antimicrobial drugs was tested using the standard dilution technique and disc diffusion test. Resistance against one or more antibiotics was found in 95.4% of E. coli O157. Only one strain was sensitive to all tested antibiotics." . "Occurrence of Escherichia coli O157 in raw material and food in Czech Republic"@en . .
