Abstract

We report the detection of Salmonella carrying bla(CTX-M) in U.S. livestock populations. We identified 12 of 2,034 (0.6%) Salmonella isolates originating from turkeys, horses, and pigs from at least 6 U.S. states, all carrying bla(CTX-M-1), many on a pandemic sequence type 1 IncN plasmid.
