Actinomycosis

Actinomycosis is mainly a chronic purulent inflammation caused by actinomyces israeli. Fistulas form and flow out of pus with sulfur-colored particles. According to modern biological classification, actinomycetes are not a fungus but an anaerobic bacterium. Because it causes lesions similar to mycosis, and in accordance with past habits, actinomycosis is often still described with mycosis. Actinomycetes have a cell wall, which is similar in chemical composition to bacteria and has no nuclear membrane. The mycelia are filamentous, similar to fungi, and the thickness of mycelium is similar to that of common bacilli, and the diameter is generally not more than 1 μm. The hypha branch can be broken into rods. With the widespread application of antibiotics, the incidence of this disease has a downward trend.
