Overview
Actinomycosis is a rare infectious bacterial disease of humans generally caused by Actinomyces israelii, A. gerencseriae and Propionibacterium propionicus, though the condition is likely to be polymicrobial.Characterized by the formation of painful abscesses in the mouth, lungs, or digestive organs, actinomycosis abscesses grow larger as the disease progresses, often over a period of months. In severe cases, the abscesses may penetrate the surrounding bone and muscle to the skin, where they break open and leak large amounts of pus. Actinomycosis occurs in cattle and other animals as a disease called lumpy jaw. This name refers to the large abscesses that grow on the head and neck of the infected animal.
Historical Perspective
Acitnomycosis was first identified in 1877 in cattle by pathologist Otto Bollinger. Later in the year, James Israel discovered it in humans and classified it under fungal origin. In 1939, Bergey classified to be bacteria.
Classification
Actinomycosis can be classified based on the anatomical site involved into[1]
- Orocervicofacial actinomycosis
- Thoracic actinomycosis
- Abdominopelvic actinomycosis
- central nervous system actinomycosis
- Musculoskeletal actinomycosis
- Disseminated actinomycosis
Pathophysiology
Actinomycosis is a chronic pyogenic bacterial infection caused by Actinomyces species. Infection most frequently follows dental work, trauma, surgery, or other medical conditions. When there is break in the mucosa, anywhere from the mouth to the rectum they reach tissues and cause damage. Incubation period of Actinomycosis varies from one to four weeks. But occasionally, it may be as long as several months. Actinomycosis elicits both humoral and cell-mediated immune responses.[2][3][4][5][6][7]
