| ABSTRACT The present study evaluated the antimicrobial susceptibility profile, β-lactamase production, and genetic diversity of Enterobacteriaceae, Pseudomonas aeruginosa, and Acinetobacter spp. using phenotypic identification, antimicrobial susceptibility testing, and β-lactamase phenotypic detection. Isolates were obtained from patients in an intensive care unit in a hospital in southern Brazil. Bacterial genomic DNA was extracted, followed by the genotypic detection of carbapenemases and enterobacterial repetitive intergenic consensus-polymerase chain reaction (ERIC-PCR). Fifty-six isolates (26 Klebsiella pneumoniae, five Escherichia coli, three Enterobacter aerogenes, nine P. aeruginosa, and 13 Acinetobacter spp.) were evaluated. The phenotypic... |
