Abstract

Nocardia species are difficult to identify, saprophytic, aerobic actinomycetes that are associated with high mortality rates and primarily affect immunocompromised hosts. Recently, the number ofdiagnoses of Nocardia cyriacigeorgica has grown in the United States, yet complicated clinical diagnosis and costly identification methods presume an underestimation of its presence in patients. We describe a case of brain abscess secondary to a pulmonary infection in an elderly, diabetic, Afghani man with an extensive history of chewing tobacco use.

Keywords: actinomyces; aerobic bacteria; brain abscess; diabetes; gram-positive bacteria; infectious disease; lung abscess; nocardia; nocardia cyriacigeorgica; tobacco.
