Résumé : | [BDSP. Notice produite par INIST aR0xvovQ. Diffusion soumise à autorisation]. Virulence factors of Verotoxin-producing Escherichia coli (VTEC) strains isolated from hamburgers and ground beef were studied in Argentina by PCR. Their virulence profiles were correlated with those corresponding to strains isolated from calves and adult cattle. Most virulent profiles (VTs+eae+Mp+) were present in E. coli from healthy and diarrheic calves corresponding to O5 : H-O5 : H27, O20 : H ? O26 : H11, O38 : H ? O103 : H-O103 : H2, O111 : H-O118 : H16, O165 : H-serotypes. The presence of the eae gene was significantly more frequent among VTEC strains isolated from calves (20/26 ; 76%) than from adult cattle (1/39 ; 2.5%) (p |
