Abstract

In this study thirty-eight strains of Salmonella enterica serovar Infantis isolated in Marche Region from human cases, food, animal and environmental samples were analyzed by Pulsed-Field Gel Electrophoresis (PFGE). All strains were typed by the DNA macro-restriction patterns obtained following PFGE of XbaI digests, while antimicrobial susceptibility testing of isolates was performed by the standardized disk diffusion method. The analysis of PFGE patterns by Bionumerics software demonstrated a strong similarity of S. infantis XbaI profiles, while the antimicrobial susceptibly testing showed less homogeneity.
