  Objectives: To describe the molecular characterization of CTX-M ESBL (Extended-spectrum Beta-lactamase)- producing Salmonella co-resistant ciprofloxacin and cefotaxime from chicken carcasses in 2014 in Qingdao, China. Methods: A total of 62 Salmonella isolates were confirmed as ESBLs by a combination disc diffusion test from 355 Salmonella isolates studied. Antimicrobial susceptibility was determined by the broth dilution method. CTX-M subtypes, Quinolone Resistance-determining Regions (QRDRs), Plasmid-mediated Quinolone Resistance (PMQR) determinants and Multi-locus Sequence Typing (MLST) were identified using PCR (Polymerase Chain Reaction) and sequencing. Plasmids were characterized by S1-nuclease PFGE, PCR-based replicon typing and transformation. Broth mating assays were carried out for all isolates to determine .. Read More»
