Bacteremia por Acinetobacter radioresistens adquirida na comunidade: relato de caso

Abstract

This is the description of the first case of community-acquired bacteremia caused by Acinetobacter radioresistens in Brazil. Pure culture on MacConkey agar was obtained from the blood of a 73-year-old male patient with Alzheimer's and Parkinson's disease. Gram staining and biochemical tests identified the strain as belonging to the Acinetobacter baumanni complex, but the MALDI-TOF system identified as A. radioresistens. Antimicrobial susceptibility testing and blaOXA-23 gene detection were performed using diffusion and PCR techniques, respectively. The strain was sensitive to all antibiotics tested, including carbapenems, despite bearing the blaOXA23 gene. Acinetobacter radioresistens can be considered an important agent of opportunistic infections in immunocompromised patients.
