Characterization of quinolone resistance in Salmonella spp. isolates from food products and human samples in Brazil

Abstract: Non-typhoidal salmonellosis is an important zoonotic disease caused by Salmonella enterica. The aim of this study was to investigate the prevalence of plasmid-mediated quinolone resistance in Salmonella spp. and its association with fluoroquinolone susceptibility in Brazil. A total of 129 NTS isolates (samples from human origin, food from animal origin, environmental, and animal) grouped as from animal (n = 62) and human (n = 67) food were evaluated between 2009 and 2013. These isolates were investigated throu… Show more

“…Nevertheless, plasmid‐mediated quinolone resistance in Salmonella is an alternative resistance mechanism that employs an enzyme to shield DNA gyrase and type IV topoisomerase from quinolone inhibition (Al‐Gallas et al, ; van Hoek et al, ). The horizontal transmission of qnr genes increases resistance to quinolones such as ciprofloxacin, which could explain why one serovar was only resistant to ciprofloxacin but not to nalidixic acid (Aldred et al, ; Ata, Yibar, Arslan, Mustak, & Gunaydin, ; Cavaco & Aarestrup, ; Ferrari et al, ; Pribul et al, ).…”
