Plasmid mediated quinolone resistance (PMQR) has been revealed to play not only a significant role in quinolone resistance but also this drug resistance can spread from one bacterium to another. There is limited data regarding the prevalence of PMQR are available from Bangladesh. So, the aim of this study was to detect the prevalence of qnr and aac(6')-Ib-cr genes among clinical isolates of ciprofloxacin resistant Proteus spp. This cross-sectional study was carried out in the Department of Microbiology of Dhaka Medical College, Dhaka, Bangladesh from July 2018 to June 2019. Fourty (40) Proteus spp. was isolated from 300 culture positive samples. Proteus mirabilis and Proteus vulgaris were identified by culture and biochemical test. Antibiotic susceptibility was performed by disc-diffusion technique. Quinolone resistance genes (qnrA, qnrB, qnrC, qnrD, qnrS and aac(6')-1b-cr) among ciprofloxacin resistant Proteus spp. were detected by PCR. Thirty (75%) ciprofloxacin resistant isolates were detected during disk-diffusion technique. Among them, quinolone resistance genes were found positive 11(36.67%) for aac(6')-Ib-cr, 6(20%) for qnrA, 5(16.67%) for qnrD, 4(13.33%) for qnrS and 3(10%) for qnrB genes. Co-existance of qnrA + aac(6')-Ib-cr and qnrD + qnrS were found in 3(10%) wound swab & pus and urine samples respectively followed by qnrA + qnrB in 2(6.67%) wound swab and pus and qnrA+qnrS in 1(3.33%) urine sample. The results of this study showed presence of high (66.67%) percentage of PMQR genes as well as high (30%) rate of co-carriage of the two genes among Proteus spp. isolates. The incidence of PMQR genes was found to be high which could be due to the increased prescription of fluoroquinolones. Thus, there is a need for rational usage of fluoroquinolones.
