Antimicrobial resistance genes in multidrug-resistant Salmonella enterica isolated from animals, retail meats, and humans in the United States and Canada.

ABSTRACT: Salmonella enterica is a prevalent foodborne pathogen that can carry multidrug resistance (MDR) and pose a threat to human health. Identifying the genetics associated with MDR in Salmonella isolated from animals, foods, and humans can help determine sources of MDR in food animals and their impact on humans. S. enterica serovars most frequently carrying MDR from healthy animals, retail meats, and human infections in the United States and Canada were identified and isolates resistant to the largest number of antimicrobials were chosen. Isolates were from U.S. slaughter (n=12), retail (9), and humans (9), and Canadian slaughter (9), retail (9), and humans (8; total n=56). These isolates were assayed by microarray for antimicrobial resistance and MDR plasmid genes. Genes detected encoded resis
