What could acuse the actinomycosis in my abdomen?

Actinomycosis: Actinomycosis is a germ that can cause intra-abdominal infections. In women, this could relate to an IUD, since bacteria in general like to have some sort of scaffold or support for them to get started. There are billions upon billions of bacteria living in us and on us, somehow these pathogens were allowed to flourish. An infectious diseases doc could have more answers, and investigation is good

Abdominal actinomycosis can be caused by infections, surgery or trauma (i.e. appendicitis with perforation, diverticulitis with perforation, emergency surgery to lower GI tract, ingestion of foreign body that perforates GI tract or prolonged IUD placement.) https://www.sciencedirect.com/topics/pharmacology-toxicology-and-pharmaceutical-science/abdominal-actinomycosis
