Abstract: the analysis of the results of a microbiological study of secretions after medical abortion in 143 women who had previously had inflammatory gynecological diseases, the etiological factor of which was chlamydial infection (Chl. Trachomatis), was carried out. All women examined in this paper signed an informed consent to participate in a research program and an agreement on non-disclosure of personal data. Excretion of the genital tract to detect chlamydial infection by PCR after medical abortion was performed daily for 5 days. In women with the advent of Chl. trachomatis in secretions from the genital tract after medical abortion, which used barrier contraception, in addition, after 30 days, PCR analysis of the material from C, V and U was carried out, with parallel determination of Ig M and Ig G in blood serum. When studying secretions from the genital tract using PCR, it was found that in 69 (48.3 ± 4.1%) of 143 women, Chl. Trachomatis was detected during the first 3 days after a medical abortion. 1 month after a medical abortion, a control gynecological examination was performed of 54 (37.8 ± 3.9%) women who used barrier contraception after medical abortion out of 69 (48.3 ± 4.1%) in whom in the early postabortion period Chl. trachomatis. It was established that 21 (14.7 ± 3.9%) of them showed the effects of sluggish cervicitis, and Chl. trachomatis was detected in a PCR study of scrapings from the cervix in 15 (10.5 ± 2.5%). The obtained results testified to the pathogenetic significance of the activation of persistent chlamydial infection in the development of complications after a medical abortion, even with negative results of examination on the UGC before its implementation.
