Actinomycosis is a bacterial infection that can cause sinus tracts and abscesses that contain sulfur granules, which are small, hard "nuggets" made of bacterial colonies. The disease is more common in immunosuppressed patients. Gas gangrene, pseudomembranous colitis, and myonecrosis do not typically present with sulfur granules.
