ABSTRACT

Isolation and biochemical and molecular identification of 303 strains of Escherichia coli obtained from diarrheic and healthy young alpacas of Puno-Peru, were realized. PCR amplification for 7 virulence factor genes associated with STEC, STEC O157:H7, EPEC: sxt1, sxt2, rfbO157, fliCH7, hlyA, eae y bfp were determined. A total of 39 strains (12.88%) showed amplification for one or more of these genes. Twenty three strains (59%) were classified as STEC and 16 strains (41%) as EPEC. An 88.18% (34/39) of STEC and EPEC strains were obtained from healthy alpacas and only 11.82% (5/39) from diarrheic alpacas considering this specie as potential zoonotic reservoir of STEC and EPEC.
