Overview
Pathophysiology
- Actinomycosis is caused by the bacteria Actinomyces which is a normal commensal of the human oral cavity but less common in the female genital tract and lower gastrointestinal tract.
- The common clinical forms of are:
- Cervicofacial actinomycosis (lumpy jaw)
- Thoracic actinomycosis
- Abdominal actinomycosis
- Pelvic actinomycosis
- Dermatologic actinomycosis
- Pediatric actinomycosis
- Opthalmological actinomycosis
Pathogenesis
- Actinomyces does not grow in oxygen rich environment. When there is a break through the protective lining surrounding the cavities (from mouth to rectum), the Actinomycetales penetrate through the deeper tissues where the bacteria grow rapidly due to low oxygen levels.[1]
