Transferable Acinetobacter baumannii plasmid pDETAB2 encodes OXA-58 and NDM-1 and represents a new class of antibiotic resistance plasmids

GR34 plasmids are found in several Acinetobacter species from diverse environments. They display considerable variation in accessory content owing to the presence of pdif sites and an array of dif modules, some of which contain antibiotic resistance genes.
