[Community-acquired Acinetobacter baumannii pneumonia]

Abstract

We report two cases of community-acquired Acinetobacter baumannii pneumonia. Although most infections occur in hospitalized patients, a few cases of community-acquired pneumonia have been described. This disease occurs predominantly in men, and is often associated with underlying conditions such as cigarette smoking, alcohol abuse, diabetes mellitus, and chronic pulmonary diseases. Community-acquired Acinetobacter baumannii pneumonia cases are generally reported from tropical areas, especially during wet season. Microbiological identification in blood or sputum can be difficult because of frequent misinterpretation and possible confusion with Staphylococcus or Haemophilus infuenzae or neisseriae. Early antibiotherapy is required because of the fulminant clinical course, with approximatively 50% fatality rate.
