Overview

Common risk factors in the development of Actinomycosis include dental abscess, oral surgery, and facial trauma.

Risk Factors

Actinomycosis is usually caused by an anaerobic bacteria called Actinomyces israelii, which is a common and normally not disease-causing (nonpathogenic) organism found in the nose and throat. Because of the bacteria's normal location in the nose and throat, actinomycosis most commonly appears in the face and neck. However, the infection can sometimes occur in the chest (pulmonary actinomycosis), abdomen, pelvis, or other areas of the body. The infection is not contagious. Symptoms occur when the bacteria enters the facial tissues after trauma, surgery, or infection. A common triggering cause is dental abscess or oral surgery. The infection has also been seen in certain women who have had an intrauterine device (IUD) to prevent pregnancy.

Types	Risk Factors
Cervicofacial actinomycosis
Thoracic actinomycosis	Poor dental hygiene Alcoholism Seizure disorder
Abdominal actinomycosis
Pelvic actinomycoss
CNS actinomycosis	Dental caries or infection Dental manipulation Head trauma Abdominal surgery Sinusitis, mastoiditis or chronic otitis tetralogy of fallot Chronic osteomyelitis Infected IUD
