In this study, the bioserotype distribution, virulence potential, the antimicrobial susceptibility, and the genomic diversity of Y. enterocolitica isolates recovered from Argentina and Chile were assessed. Eight Chilean and 22 Argentine isolates recovered from human (7) and animal feces (3), foods (18) and wastewater (2) were analyzed. They belonged to the bioserotypes B2 O:9 (9), B1A O:5 (8), B1A O:41,42‐41,43 (8), B4 O:3 (3) and B1A O:7,8‐8‐8,19 (2). Autoagglutination (AA), Ca2+‐dependent growth at 37°C and yadA, inv and yst genes were observed in B2 O:9 and B4 O:3 strains. B1A strains exhibited the genotype yadA‐ inv‐ yst+. All strains were resistant to ampicillin, rifampicin and erythromycin. By XbaI‐PFGE, 11 genomic types (GTs) were demonstrated (D.I. 0.90). The characteristics of these Y. enterocolitica isolates highlight the importance to maintain active surveillance of this enteropathogen in both count...
