Actinomycosis
Definition
Actinomycosis is a bacterial infection that results in abscesses (collections of pus) in the abdominal cavity, jaw (cervicofacial), lungs (thoracic), or all over the body (generalized actinomycosis). This condition can be treated, so contact your doctor if you think you may have actinomycosis.

Causes
Actinomycosis is most often caused by infection by the bacterium, Actinomyces israelii , which is present in the gums, teeth, and tonsils.
Risk Factors
A risk factor is something that increases your chance for getting a disease or condition. The following factors increase your chance of developing actinomycosis. If you have any of these risk factors, tell your doctor:
- Dental disease
- Trauma
- Aspiration (liquids or solids are sucked into lungs)
Symptoms
If you experience any of these symptoms do not assume it is due to actinomycosis. These symptoms may be caused by other, less serious health conditions. If you experience any one of them, see your physician.
- Pain
- Fever
- Vomiting
- Diarrhea
- Constipation
- Weight loss
- Drainage of pus through the skin
- Small, flat, hard, sometimes painful swellings around the mouth, neck, or jaw, which may discharge pus
- Sputum-producing cough
Diagnosis
Your doctor will ask about your symptoms and medical history, and perform a physical exam. Tests may include the following:
- Analyses of pus, sputum, or tissue
- X-ray
