First Report of a Foodborne Salmonella enterica Serovar Gloucester (4:i:l,w) ST34 Strain Harboring bla _{CTX-M- 55} and qnrS Genes Located in IS26-Mediated Composite Transposon.

ABSTRACT: Extended-spectrum β-lactamases (ESBLs) production and (fluoro)quinolone (FQ) resistance among Salmonella pose a public health threat. The objective of this study was the phenotypic and genotypic characterization of an ESBL-producing and nalidixic acid-resistant Salmonella enterica serovar Gloucester isolate (serotype 4:i:l,w) of sequence type 34 (ST34) from ready-to-eat (RTE) meat products in China. Whole-genome short and long read sequencing (HiSeq and MinION) results showed that it contained bla _{CTX-M- 55}, qnrS1, and tetB genes, with bla _{CTX-M- 55} and qnrS1 located in chromosomal IS26-mediated composite transposon (IS26-qnrS1-IS3-Tn3-orf-bla _C
