Characterization of antimicrobial resistance of Salmonella Newport isolated from animals, the environment, and animal food products in Canada.

ABSTRACT: Multi-drug-resistant (MDR) Salmonella enterica serovar Newport strains are increasingly isolated from animals and food products of animal origin and have caused septicemic illness in animals and humans. The purpose of this study was to determine the occurrence and the epidemiologic, phenotypic, and genotypic characteristics of S. Newport of animal origin that may infect humans, either via the food chain or directly. During the 1993-2002 period, the Office International des Epizooties Reference Laboratory for Salmonellosis in Guelph, Ontario, received 36 841 Salmonella strains for serotyping that had been isolated from animals, environmental sources, and food of animal origin in Canada. Of these, 119 (0.3%) were S. Newport. Before 2000, none of 49 S. Newport strains was resistant to more th
