# Acinetobacter radioresistens Bacteremia in Complicated Pneumonia. A Case Report and Literature Review

## TL;DR

This paper reports the first case of Acinetobacter radioresistens infection showing resistance to some antibiotics, highlighting its potential role in spreading antibiotic resistance.

## Contribution

First reported case of Acinetobacter radioresistens infection with resistance to sulfamethoxazole-trimethoprim and intermediate sensitivity to other antibiotics.

## Key findings

- The infection was resistant to sulfamethoxazole-trimethoprim.
- The isolate showed intermediate sensitivity to meropenem and ciprofloxacin.
- This case highlights the potential of A. radioresistens to spread resistance genes.

## Abstract

Acinetobacter radioresistens
, a ubiquitous non‐pathogen microorganism, is the source of the class D carbapenemase OXA‐23 being therefore a potential disseminator of resistance genes in Acinetobacter spp. At present few cases of human infections have been reported in the literature, all sensible to beta‐lactams. The present paper reports for the first time an infection by
Acinetobacter radioresistens
showing resistance to sulfamethoxazole‐trimethoprim and intermediate sensitivity to meropenem and ciprofloxacin.
