Objective(s): Plasmid-mediated quinolone resistance (PMQR) determinants and integrons have a considerable contribution to bacterial drug resistance in Gram-negative pathogens. We studied the prevalence of PMQR genes and integron carriage in multidrug-resistant community isolates of Klebsiella spp.Materials and Methods: Two hundred and fi...

Studies to understand the role wastewater treatment plants (WWTPs) play in dissemination of antibiotics (ABs), and emergence antibiotic resistance (ABR), an important tackling this global crisis. Here we describe abundance distribution 16 ABs, 4 corresponding genes (ARGs), sampled from influent five WWTPs within a single river catchment. We consider four classes antibiotics: fluroquinolones, ma...

Introduction: In recent years, antibiotic resistance has been on the rise, leading to limited ways to control nosocomial infections (especially surgical site infections) and the right treatment options. The main purpose of this study was the pattern of antibiotic resistance and the frequency of plasmid-dependent quinolone resistance (qnr) genes in Pseudomonas aeruginosa, Escherichia coli and Kl...

Municipal wastewater treatment facilities are considered to be "hotspots" for antibiotic resistance, since they conjoin high densities of environmental and fecal bacteria with selective pressure in the form of sub-therapeutic concentrations of antibiotics. Discharged effluents and biosolids from these facilities can disseminate antibiotic resistant genes to terrestrial and aquatic environments,...

Abstract Background This study was aimed to determine the prevalence of qnr genes among fluoroquinolone-resistant Escherichia coli (FREC) isolates from Nigeria. Antimicrobial susceptibility testing performed by disc diffusion technique. Polymerase chain reaction used identify ( E. ) and for detection genes. Results A total 206 non-duplicate were isolated 300 clinical specimens analyzed. In all,...

Sir, Quinolone resistance in Enterobacteriaceae usually results from mutations in genes coding for chromosomally encoded type II topoisomerases, efflux pumps or porin-related proteins. Recently, transferable, plasmid-borne, quinolone resistance genes—qnrA, qnrB, qnrS, cr variant of aac(60)-Ib, qepA and oxqB—have been observed in clinical isolates, more frequently among strains producing plasmid...

Background: The emergence and spread of multidrug-resistant bacteria have become a major public health problem worldwide, particularly in developing countries such as Burkina Faso. This study aims to determine phenotypic genotypic antibiotic resistant diarrheagenic Escherichia coli (DEC) from patients with diarrhea Ouagadougou, Methodology: Microbiological biochemical analysis were done detect ...

Antimicrobials are commonly used in conventional livestock production and manure is widely applied to agricultural lands as fertilizer. This practice raises questions regarding the effects of fertilization on (i) soil microbiota composition (ii) spread antimicrobials antimicrobial resistance (AMR) environment. study was conducted a high-density farming area Northern Italy aimed at assessing imp...
