Virulence and antimicrobial resistance factors in serotypes isolated from pigs and chickens in central Chile.

is a food-borne pathogen with a wide host-range that during decades has been of public health concern in developed and developing countries. In Chile, the poultry and pig industries represent the biggest contribution of meat consumption in the population, and sanitary regulations have been imposed for control. The aim of this work was to determine and characterize strains isolated from pigs and chicken raised on commercials farms in Chile.
