Nocardia can usually be differentiated from Actinomyces by acid-fast staining, as Nocardia typically exhibit varying degrees of acid fastness due to the mycolic acid content of the cell wall.

Pap smear can detect the presence of Actinomyces organisms, which are seen as branching filaments, sulfa granules or irregular islands of amorphous material which stain blue to brown or black.

Management is with long-term penicillin and surgery, if needed Drainage or infected tissue may have the characteristic yellow sulfur granules associated with Actinomyces. Untreated cases of actinomycosis result in chronic, progressive disease

Antibiotics are used to treat actinomycosis and, in severe cases, surgery is required to remove lesions.
