Abstract

ABSTRACT Nontyphoidal Salmonella (NTS) causes an estimated 1.2 million illnesses, 23,000 hospitalizations, and 450 deaths each year in the United States. Decreased susceptibility to ciprofloxacin (DSC) has historically been associated with chromosomal mutations of the quinolone resistance determining region (QRDR), but plasmid-mediated quinolone resistance (PMQR) genes are increasing. To investigate DSC among Salmonella enterica serotype Newport strains, we examined 40 isolates from 1996 to 2016 with DSC. Thirty isolates (71%) contained the PMQR gene qnrB and eight isolates (19%) contained a QRDR.
