Nocardiosis in the community hospital. Report of three cases.

Nocardiosis is an infectious disease that occurs in both normal and immunocompromised hosts. In North America, the most common presentation is that of primary subacute pneumonia. In Central and South America, primary cutaneous infections are more common. The diagnosis is often missed because of contamination of cultures and the need to culture specimens for extended periods. Because of this difficulty in diagnosis, the incidence of nocardiosis may actually be higher than what published data reveal. Incision and drainage of abscesses and extended drug therapy (eg, with sulfonamides) are the cornerstones of treatment.
