Actinomycosis pulmonary
Definition
Pulmonary actinomycosis is a lung infection caused by the bacteria actinomyces or propioni.
Alternative NamesActinomycosis pulmonary
Causes
The organisms that cause actinomycosis are normally found in the mouth and gastrointestinal tract, where they do not usually cause harm. However, poor dental hygiene and dental abscess can increase a person's risk for face sores and lung infections caused by these bacteria.
Alcohol abuse is associated with actinomycosis.
Actinomycosis in the lungs causes lung cavities, lung nodules, and pleural effusions. The disease is rare and may occur at any age, but most patients are 30-60 years old. Men are more frequently affected than women.
Symptoms
- Lethargy
- Weight loss
- Fever
- Cough with sputum

Exams and Tests
- CBC

- Culture of specific tissue
- Bronchoscopy with culture
- Lung biopsy
- Thoracentesis with culture
- Tissue and fluid analysis for sulfur granules
Treatment
The goal of treatment is to control the infection. However, many patients are slow to respond to treatment. Long-term use of penicillin is needed to cure the condition. Alternative antibiotics such as tetracyclines, macrolides, or clindamycin may be used in patients who cannot take penicillin.
Surgery may be necessary to drain fluid from the lung area and control the infection.
Outlook (Prognosis)
The probable outcome is good after treatment with antibiotics.
Possible Complications
