A total of 225 isolates of Salmonella enterica serovar Typhimurium from food-producing animals collected between 2003 and 2007 were examined for the prevalence of plasmid-mediated quinolone resistance (PMQR) determinants, namely qnrA, qnrB, qnrC, qnrD, qnrS, qepA and aac(6')Ib-cr, in Japan. Two isolates (0.8%) of S. Typhimurium DT104 from different dairy cows on a single farm in 2006 and 2007 were found to have qnrS1 on a plasmid of approximately 9.6-kbp. None of the S. Typhimurium isolates had… Expand
Prevalence and characterization of plasmid-mediated quinolone resistance genes in Salmonella isolated from poultry in Korea
TLDR
This report is the first to describe the detection of qnr genes in Salmonella spp. Expand
Detection of aac(6’)-Ib-cr in Avian Pathogenic Escherichia coli Isolates in Japan
TLDR
This is the first report of the aac (6’)-Ib-cr gene in bacteria from food-producing animals in Japan, and it is shown to belong to phylogenetic group A, sequence type 167 and untypable serogroup. Expand
Quinolone Resistance Mechanisms Among Salmonella enterica in Malaysia.
TLDR
Overall, mutations in gyrA and the presence of qnrS1 genes might have contributed to the high level of quinolone resistance among Salmonella strains circulating in Malaysia. Expand
Quinolone susceptibility and genetic characterization of Salmonella enterica subsp. enterica isolated from pet turtles
TLDR
Results suggest that studied strains of S. enterica isolated from pet turtles are susceptible to quinolones and genetically more conserved with regards to gyrA gene region. Expand
Molecular Characterization of CTX-M Producing Salmonella Isolates with Concurrent Resistance to Ciprofloxacin and Cefotaxime from Slaughtered Chicken Carcasses in Qingdao, China
TLDR
The emergence of CTX-M, QRDR and PMQR were found in ciprofloxacin and cefotaxime coresistant Salmonella, especially S. indiana among chicken carcasses in Qingdao. Expand
Multiple transmissible genes encoding fluoroquinolone and third-generation cephalosporin resistance co-located in non-typhoidal Salmonella isolated from food-producing animals in China.
TLDR
The presence of multidrug-resistant bacteria in food-producing animals in countries that export foodstuffs suggests that global transfer of antibiotic resistances from country to country on food is possible. Expand
Detection of extended spectrum beta-lactamases and resistance in members of the Enterobacteriaceae family isolated from healthy sheep and dogs in Umuarama, Paraná, Brazil.
TLDR
Findings indicate the presence of MR bacteria in the normal microbiota of the animals studied, which can contribute to the dissemination of antimicrobial resistance to other animals, environment, and/or human beings. Expand
Molecular characterization of antibiotic-resistant Salmonella isolates from retail meat from markets in Northern Vietnam.
TLDR
The data revealed that resistant Salmonella strains were widely distributed in Northern Vietnam via the food chain and that they might contain multiple genes specifying identical resistance phenotypes, and further studies are necessary to clarify the mechanisms of antibiotic resistance in Salmoneella strains and their spread in the livestock market.

Research Note: Longitudinal monitoring of chicken houses in a commercial layer farm for antimicrobial resistance in Escherichia coli with special reference to plasmid-mediated quinolone resistance
TLDR
Results suggest that despite the low prevalence of quinolone resistance in this farm, various PMQR genes, located on diverse plasmids, exist. Expand
High prevalence and molecular characteristics of multidrug-resistant Salmonella in pigs, pork and humans in Thailand and Laos provinces.
TLDR
Multidrug-resistant Salmonella was common in pigs, pork and human samples in this region and carried mobile genetic elements and resistance genes on conjugative plasmids that could be readily transferred to other bacterial species. Expand
