Streptomyces pneumonia in a patient with human immunodeficiency virus infection: case report and review of the literature on invasive streptomyces infections

Abstract

Streptomyces species are most widely known for their production of antimicrobial substances and, apart from mycetoma, have rarely been reported as a cause of infection. We describe a patient with early human immunodeficiency virus infection who presented with fever, cough, and nodular pulmonary infiltrates. Open lung biopsy revealed necrotic tissue and a sulfur granule; aerobic bacterial cultures yielded Streptomyces species. The patient was treated successfully with clarithromycin for 6 months. We review the clinical presentation and treatment of invasive streptomyces infections.
