Detection and characterization of multidrug‐resistant <i>Salmonella enterica</i> serovar Infantis as an emerging threat in poultry farms of Faisalabad, Pakistan

Abstract

AIMS: The aim of this study was the molecular identification of Salmonella enterica serovar Infantis (S. Infantis) isolated from poultry samples and their antimicrobial resistance and virulence profiling. METHODS AND RESULTS: (44·4%). Among efflux pump coding genes, armA showed highest (74·2%) prevalence and for virulence, a high prevalence of SopE (89·2%) showed the zoonotic potential of the isolates. The activity of efflux pumps was detected through Ethidium Bromide-agar method. CONCLUSIONS: Poultry could act as reservoirs of multidrug resistance Salmonella. SIGNIFICANCE AND IMPACT OF THE STUDY: We firstly report the prevalence and molecular characterization of virulence/drug resistance in S. Infantis from this region and the results may contribute to designing precisely targeted therapy. This study has also highlighted the possible emergence of S. Infantis with zoonotic potential.
