A30-A49: Other bacterial diseases
A42: Actinomycosis
Actinomycosis is a chronic infection caused by a family of bacteria known as Actinomyces. These bacteria are generally harmless and are commonly found in the mouth, nose, and throat. They may occasionally cause disease, however, after penetrating the body's protective barriers due to injuries, surgery, or oral diseases, leading to an actinomycosis infection. Symptoms generally emerge slowly and can vary greatly depending on which part of the body is affected. Influenceable areas include the lungs, skin, or the central nervous system. In most cases, individuals may experience lumps or sores on the affected area, which may progress to form long-term (chronic) abscesses that produce a pus discharge. This condition can progressively worsen over a long period of time if left untreated, potentially affecting other systems in the body.
