Resumo

Most known plasmids are identified by conferring virulence or antimicrobial resistance phenotypes and such characteristics aid in the success of the dispersion of different plasmid types between bacteria from different sources. This study aimed to perform the subtyping of the plasmid-mediated quinolone resistance, detected in Salmonella spp. A total of 34 Salmonella strains non-susceptible to ciprofloxacin were evaluated. Strains were selected based on the presence of PMQR determined by Polymerase Chain Reaction and further submitted to Next Generation Sequencing. Most of the strains presented the qnrB19 in small ColE-like plasmids and qnrB2 gene associated with IncN/ST5 plasmids also detected. Our results indicated the co-occurrence of PMQR and ESBLs in plasmids that are a lineage of epidemic plasmids circulating in Salmonella in which additional resistances were detected, highlighting the potential threat of resistance Salmonella to public health, particularly in infections in which antimicrobial therapy is needed.
