title: Pelvic colonization with Actinomyces in women using intrauterine contraceptive devices.
abstract: Recent reports suggest a relationship between intrauterine contraceptive device (IUD) use and colonization or infection of the genital tract with Actinomyces species. This prospective, case-controlled study was designed to determine the incidence of colonization or infection with Actinomyces in IUD users. None of 50 control patients and four of 50 study patients (8%) had Actinomyces identified. None of the patients with positive results had symptomatic pelvic infection. Cervical cytology was effective in detecting each of the four study patients with positive results. It appears that the presence of any type of IUD is a major predisposing factor to colonization with Actinomyces.
