Erysipelothrix rhusiopathiae pneumonia in an immunocompetent patient.

Erysipelothrix rhusiopathiae is a Gram-positive bacillus that causes infections primarily in animals. In humans, this bacterium usually causes localized cutaneous infections called erysipeloid. Here we report a case of pneumonia with isolation of E. rhusiopathiae from bronchoalveolar lavage and sputum. To our knowledge, this is the first report of a pneumonia case caused by E. rhusiopathiae confirmed by culture.
