Actinomycosis (A42)
Clinical Information
Actinomyces - A genus of gram-positive, rod-shaped bacteria whose organisms are nonmotile. Filaments that may be present in certain species are either straight or wavy and may have swollen or clubbed heads.
Actinomycosis - Infections with bacteria of the genus ACTINOMYCES.
Actinomycosis, Cervicofacial - A form of ACTINOMYCOSIS characterized by slow-growing inflammatory lesions of the lymph nodes that drain the mouth (lumpy jaw), reddening of the overlying skin, and intraperitoneal abscesses.
Typhlitis - Necrotizing inflammation of the CECUM ("typhlon" in Greek), sometimes spreading to the APPENDIX and/or the ILEUM. Symptoms include ABDOMINAL PAIN and DIARRHEA. Its pathogenesis is multifactorial. Typhlitis is often associated with NEUTROPENIA and chemotherapy in immunocompromised individuals (IMMUNOCOMPROMISED HOST).

An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
