Abstract
Carbapenemase production is an important mechanism of carbapenem resistance among nonfermentative Gram-negative isolates. This study aimed to report the detection of bla(OXA-58) gene in multiresistant clinical isolates of Acinetobacter baumannii recovered from inpatients in a public hospital. Polymerase chain reaction tests were performed to detect the bla(OXA-23-like), bla(OXA-24-like), bla(OXA-58-like) and bla(OXA-51-like) genes. The bla(OXA-58) and bla(OXA-23) genes were detected in one and three isolates, respectively. Sequencing of the bla(OXA-58-like) amplicon revealed 100% identity with the A. baumannii bla(OXA-58) gene listed in the GenBank database. This is the first report of an OXA-58-producing A. baumannii isolate in Rio de Janeiro, Brazil.
