Novel genetic environment of plasmid-mediated quinolone resistance gene qnrB2 in Salmonella Bredeney from poultry.

摘要

Plasmid-mediated quinolone resistance (PMQR) in Enterobacteriaceae of human origin is an emerging problem in Europe. A variety of qnrA, qnrB and qnrS genes are commonly isolated from Enterobacteriaceae of human origin, and qnr genes have been detected in several Salmonella enterica serotypes in Europe, the USA, Africa, Australia and Asia. However, few reports describe the occurrence of PMQR among bacteria from food-producing animals. The presence of these genetic traits in bacteria isolated from food-producing animals may constitute a public health concern, since the transfer of resistant bacteria or mobile resistance determinants between animals and humans via the food chain or by direct contact has been suggested.
