Molecular characterization and antibiotic resistance of salmonella serovars isolated in the Apulia region of Italy

During the period January 2013 December 2015, 175 cases of human salmonellosis were reported in the Apulia Region of Italy.The aim of this study was to characterize Salmonelle strains from the standpoint of serovars prevalence,antimicrobial resistance and clonal origin. All the strains were tested by pulsed-field gel electrophoresis ( PFGE) according to the PulseNet Protocol and cluster analysis was performed using BioNumerics Software. Molecular typing by PFGE yelded 60 different macrorestriction profiles among 33 serotypes.
