Abstract

Salmonellosis is an important disease in animals and human which is caused by different serovars of Salmonella enterica. Serovars Typhimurium is one of the most prevalent serovars in humans. Quinolones and fluoroquinolones are the family of extended-spectrum antibiotics which are used in salmonellosis treatment. QNR GENES are the plasmid-mediated quinolones resistance which leads to resistance in Enterobacteriaceae. The aim of this study is the identification of quinolone resistance genes qnr in SALMONELLA TYPHIMURIUM isolated from food samples. In this study, 60 Salmonella samples isolated from food was collected and confirmed by culture and biochemical tests. Serotyping was done by O and H antisera. MULTIPLEX-PCR was performed to identify qnrA, qnrB, and qnrS genes. All of the 60 isolates were confirmed as Salmonella by culture and biochemical tests. The results of serotyping showed all the 60 isolates belonged to serogroup B and serovar Typhimurium. MULTIPLEX-PCR test showed 5 samples had the qnrB, 4 had the qnrS and 1 harbored qnrA gene. The results of this study show the presence of QNR GENES in SALMONELLA TYPHIMURIUM isolated from food samples which has a specific public health importance. Therefore, there should be surveillance and monitoring programs to prevent this quinolone resistance.
