Severe Community-acquired Pneumonia Caused by Acinetobacter baumannii Successfully Treated with the Initial Administration of Meropenem Based on the Sputum Gram Staining Findings

A 62-year-old man with diabetes mellitus and a two-day history of fever and dyspnea presented at our hospital. He was diagnosed with community-acquired pneumonia (CAP), septic shock, and respiratory failure. Sputum Gram staining revealed Gram-negative coccobacilli. Based on the Gram staining finding...

Description
Summary:A 62-year-old man with diabetes mellitus and a two-day history of fever and dyspnea presented at our hospital. He was diagnosed with community-acquired pneumonia (CAP), septic shock, and respiratory failure. Sputum Gram staining revealed Gram-negative coccobacilli. Based on the Gram staining findings and history, Acinetobacter baumannii was considered as one of the causative organisms of his CAP. Consequently, he was successfully treated with the initial administration of meropenem. We suggest that A. baumannii should be considered as one of the possible causative organisms of CAP based on a fulminant clinical course, and the presence of Gram-negative coccobacilli.
