These infections may be localized or systemic, and can affect the skin, lungs, and other organs. Actinomyces can cause diseases such as actinomycosis, which is a chronic infection of the skin and soft tissues; pulmonary actinomycosis, which is an infection of the lungs; and systemic actinomycosis, which is an infection of the blood and organs. Treatment for these infections usually includes antibiotics, but surgery may be required in some cases.
