Actinomycosis is a rare infectious bacterial disease caused by the gram-positive Actinomyces species.[1] The name refers to ray-like appearance of the organisms in the granules. About 70% of infections are due to either Actinomyces israelii or A. gerencseriae.[1] Infection can also be caused by Streptomyces somaliensis and Propionibacterium propionicus. The condition is likely to be a polymicrobial anaerobic infection.[2]
