ABSTRACT
This report is the description of the first case in Brazil of community-acquired bloodstream infection caused byAcinetobacter radioresistens. A 73-year-old male patient with Alzheimer’s and Parkinson’s disease was hospitalized and diagnosed with pneumonia at a general hospital. MacConkey agar pure culture was obtained from blood cultures. Conventional tests identified the isolate as Acinetobacter baumannii complex. However, the matrix-assisted laser desorption ionization-time of flight (MALDI-TOF) technique identified it as Acinetobacter radioresistens. The isolate was sensitive to all antibiotics tested by the disk diffusion method, including carbapenem. However, blaoxa-23 gene was detected by the polymerase chain reaction (PCR) assay. Acinetobacter radioresistens can be considered an important agent of opportunistic infections in immunocompromised patients, a potential disseminator of resistance genes.
