Emergence of OXA-72-producing Acinetobacter pittii clinical isolates.
The genus Acinetobacter comprises 47 characterised genomic species, among which species belonging to the Acinetobacter calcoaceticus–Acinetobacter baumannii complex are the most clinically relevant. Within this complex, A. baumannii, Acinetobacter nosocomialis (formerly genomic species 13TU) and Acinetobacter pittii (formerly genomic species 3) are frequently associated with hospital-acquired i...
متن کاملCarbapenem-resistant Acinetobacter baumannii producing OXA-23 in Thailand.
We investigated the resistance determinant of 13 clinical isolates of carbapenem-resistant Acinetobacter baumannii collected from a regional hospital in the north of Thailand. All isolates were multidrug resistant and produced the OXA-23 carbapenemase. The bla(OXA-23) gene was found adjacent to ISAba1. Furthermore, two isolates carried the metallo beta-lactamase gene, bla(IMP). The bla(OXA-23) ...
متن کاملOXA beta-lactamase-mediated carbapenem resistance in Acinetobacter baumannii.
OBJECTIVES Acinetobacter baumannii is a significant pathogen in health care settings. In recent years, an increase in carbapenem resistance among A. baumannii due to Ambler class B metallo-beta-lactamases or class D OXA carbapenamases has been reported. In this study we detected the presence of OXA carbapenamases and coproduction of metallo-beta-lactamases (blaVIM and blaIMP ) by phenotypic and...
متن کاملA case of IMP-4-, OXA-421-, OXA-96-, and CARB-2-producing Acinetobacter pittii sequence type 119 in Australia.
An IMP-4-producing Acinetobacter pittii strain coproducing oxacillinases was isolated from a leg wound of a 67-year-old female patient. Identification to the species level by rpoB and gyrB sequencing and multiplex-PCR-based analysis revealed that the isolate was A. pittii. Whole-genome sequencing of this A. pittii isolate determined the presence of blaOXA-96, blaCARB-2, and a novel blaOXA-421 g...
متن کاملCarbapenem-resistant Acinetobacter baumannii isolates from Tunisia producing the OXA-58-like carbapenem-hydrolyzing oxacillinase OXA-97.
The basis of the beta-lactam resistance of 39 multidrug-resistant Acinetobacter baumannii isolates recovered from hospitalized patients was studied. These isolates were collected from 2001 to 2005 at the Sahloul Hospital in Sousse, Tunisia. They belonged to two distinct clones. One clone that grouped 19 isolates produced a carbapenem-hydrolyzing oxacillinase, OXA-97, that differed from OXA-58 b...
