Genetic context of bla _CTX-M-55 and qnrS1 genes in a foodborne Salmonella enterica serotype Saintpaul isolate from China.

ABSTRACT: Salmonella enterica resistant to fluoroquinolones (FQs) and extended-spectrum cephalosporins (ESCs) has been deemed a high-priority pathogen by the WHO. Salmonella enterica serovar Saintpaul (S. Saintpaul) co-resistant to ESCs and FQs and harboring corresponding resistance genes (bla _CTX-M-55 and qnrS1) have been previously reported. However, they have not been reported in China. Moreover, the genetic context and transferability of ESCs and FQs resistance genes in S. Saintpaul remain obscure. This study is the first study to characterize a multidrug-resistant (MDR) S. Saintpaul isolate (16Sal016) harboring plasmid-mediated bla _CTX-M-55 and qnrS1 genes recovered from weever fish in China.
