Pulmonary streptomyces infection in patient with sarcoidosis, France, 2012.

TO THE EDITOR: Streptomyces spp. are aerobic, gram-positive bacteria of the order Actinomycetales, known for their ability to produce antimicrobial molecules such as streptomycin. Streptomyces spp., usually saprophytic to humans, can cause local cutaneous fistulized nodules known as actinomycetoma or mycetoma. Severe invasive infections have seldom been reported, but most cases reported have occurred in immunocompromised patients (1-5). We report a case of invasive pulmonary infection caused by a Streptomyces sp. in a splenectomized patient with sarcoidosis.
