title: Markers of pathogenicity islands in strains of Aeromonas species of clinical and environmental origin.
abstract: The aim of this study was to investigate the presence of markers of pathogenicity islands that may be informative to detect the virulent PAI carriers of clinical and environmental strains of Aeromonas spp. isolated in Mexico. virB2, virB9 and virB11 genes were found in Aeromonas strains isolated from environmental and clinical sources while cagE and tfc16 genes were only in strains of environmental origin. Having performed the wide screening presented in this study, we now have a set of strains to map and confirm the presence of a pathogenicity island in Aeromonas strains isolated in Mexico.
