Multidrug-resistant Salmonella typhimurium, Pacific Northwest, United States.
We compared human and bovine isolates of Salmonella enterica using antimicrobial-drug resistance profiles and pulsed-field gel electrophoresis. From 2000 through 2006, we observed an increase in a novel multidrug-resistant clone of S. Typhimurium with no recognized phage type. This clone may represent an emerging epidemic strain in the Pacific Northwest.
