RESUMO
The incidence of infection in 100 cases of abortion was studied. Intra-uterine swabs and products of conception were cultured both aerobically and anaerobically. Significant potentially-pathogenic organisms were cultured from 94 of 100 intra-uterine swabs and from all 100 samples of the products of conception. Anaerobes were cultured from 70 intra-uterine swabs and from 56 products of conception. The spectrum and relative proportion of organisms isolated resemble those found in the normal vagina and cervical os. In addition, positive blood cultures were obtained from 24 patients, 8 on admission and 17 after evacuation. With this high incidence of infection, routine antimicrobial therapy for aerobic and anaerobic organisms should be given to all patients with abortion.
