- Abstract: Rationale: Acinetobacter radioresistens is a non-fermentative Gram-negative coccobacillus that is environmentally ubiquitous and is an uncommon cause of pneumonia in an immunocompetent patient with no known chronic medical illness. Patient concerns: A middle-aged Asian male with a smoking history presented with fever and cough. Physical examination was unremarkable. Chest imaging was consistent with pulmonary parenchymal infection and blood culture grew Acinetobacter radioresistens. Diagnosis: Community acquired pneumonia with Acinetobacter radioresistens bacteremia. Interventions: The patient received a combination of intravenous and oral ampicillin-sulbactam over 2 weeks. Outcomes: Repeat blood cultures showed resolution of bacteremia. Completion of antimicrobial treatment saw resolution of respiratory symptoms and radiological pneumonic changes. Lessons: Acinetobacter radioresistens causing community-acquired pneumonia in an immunocompetent host has never been described before. It may be a novel emerging infectious agent in pulmonary infections. Its clinical course in this immunocompetent patient appears to be relatively benign.
