Acinetobacter calcoaceticus, an aerobic gram-negative coccobacillus, is a rare cause of community-acquired pneumonia. It most commonly causes nosocomial infections, particularly in elderly debilitated patients who have undergone surgery, instrumentation, and antibiotic therapy. In a study of acute pneumonia in adults, five cases of community-acquired acinetobacter pneumonia were observed over an 11-month period. Other than chronic pulmonary disease (two patients), no serious underlying diseases existed in these patients. Lobar consolidation was the predominant radiologic pattern. The mortality rate was 40%, and mortality was directly related to therapy with inappropriate antibiotics. The reason for this relatively high prevalence of community-acquired acinetobacter pneumonia in the population studied is not known. Possible explanations include the high prevalence of chronic pulmonary disease, indiscriminate use of penicillin, and an unknown immunodeficiency state.
醋酸钙不动杆菌是一种需氧革兰氏阴性球杆菌，是社区获得性肺炎的罕见病因。它最常引起医院感染，尤其是在接受过手术、器械操作和抗生素治疗的老年体弱患者中。在一项针对成人急性肺炎的研究中，在11个月的时间里观察到5例社区获得性不动杆菌肺炎病例。除了慢性肺病（2例患者）外，这些患者没有其他严重的基础疾病。大叶实变是主要的影像学表现。死亡率为40%，死亡与使用不适当的抗生素治疗直接相关。在所研究的人群中社区获得性不动杆菌肺炎相对高发的原因尚不清楚。可能的解释包括慢性肺病的高患病率、青霉素的滥用以及未知的免疫缺陷状态。
