Abdominal disease is another manifestation of actinomycosis. There are different ways to contract actinomycosis. It is, therefore, a form of actinomycosis. "Actinomyces" bacteria are generally sensitive to penicillin, which is frequently used to treat actinomycosis. The diagnosis of actinomycosis can be a difficult one to make. Incidence of oral actinomycosis, which is harder to diagnose, has increased. The use of intrauterine devices (IUDs) has increased incidence of genitourinary actinomycosis in females. The Norwegian painter Halfdan Egedius died from actinomycosis on 2 February 1899. Violinist Joseph Joachim died of actinomycosis on 15 August 1907. The cause of death was actinomycosis, a bacterial infection that attacked the internal organs. Actinomycosis abscesses grow larger as the disease progresses, often over months. Pelvic actinomycosis is a rare but proven complication of use of intrauterine devices. Actinomycosis does not occur in isolation from other bacteria. Cutaneous actinomycosis is a chronic disease that affects the deep subcutaneous tissue of the skin. Actinomycosis is most frequently caused by "A. israelii".
