- W788568093 abstract "Escherichia coli (EPEC) and Shiga toxin Escherichia coli (STEC) are implicated in causing serious disease in humans. Due to the increased production of buffalo milk and small amount of studies on the prevalence of STEC and EPEC in buffalo this work was proposed. The objectives were to determine the prevalence of STEC and EPEC isolates from buffalo by investigating the genes stx1, stx2, eae, iha, efa1, toxB, lpfAO157/OI-141, lpfAO157/OI-154, lpfAO113, saa, ehxA and bfp; sorogrupagem and biochemical characterization of isolates and resistance profile of strains of EPEC and STEC isolates to different antimicrobial drugs. We isolated 33 strains of E. coli, of which 21 (63.6%) STEC and 12 (36.4%) EPEC, showed that 23 different genetic profiles. All isolates had more than one virulence gene. All of the genes studied only the bfp was not found in the samples. The strains isolated were sensitive to most antimicrobials tested. The serogroup O26 was the most common, followed by O157. The strains were virulence genes that are related to severe disease in humans. From the results we can say that buffaloes are major reservoirs of STEC and EPEC and the presence of strains with certain genetic profiles should be better studied." @default.
