- QnrD is a plasmid-mediated quinolone resistance (PMQR) determinant first reported in clinical Salmonella enterica isolates from China, located on nonconjugative plasmids of 4270 bp. Since then, the qnrD gene has been mostly found on plasmids around 2683 bp in Proteus and Morganella genera. However, Providencia spp. strains carrying qnrD-harboring plasmids have only been reported among clinical samples, in France and China. In this paper we describe two plasmids carrying qnrD in Providencia spp. isolated from Brazilian food and coastal waters. These plasmids present high coverage and identity with those recovered in France. Our results emphasize the relevance of the Proteeae tribe as reservoirs of qnrD and include P. rettgeri as a possible environmental carrier of this gene.
