Prevalence of Ureaplasma urealyticum, Chlamydia trachomatis, and Neisseria gonorrhoeae in gynecological outpatients, Taizhou, China

Abstract

Objectives: Ureaplasma urealyticum (UU), Chlamydia trachomatis (CT), and Neisseria gonorrhoeae (NG) are highly prevalent worldwide and may lead to some genital diseases. The objective of this large-scale study was to estimate the prevalence characteristics of UU, CT, and NG among women in Taizhou, Zhejiang Province, China. Methods: A total of 13 303 women who visited the gynecologic outpatient service of Taizhou First People's Hospital in Taizhou from 2013 to 2018 were analyzed. The testing of UU, CT, and NG was performed on the collected vaginal swabs using real-time fluorescence quantitative polymerase chain reaction (RT-PCR) method. Results: The overall infection rates of UU, CT, and NG were 62.04%, 10.20%, and 4.09% in the Taizhou-based population, respectively. The age-specific prevalence showed that younger women (age <25 years) were the preferred period for the positive detection of UU or CT, while elder women (age ≥40 years) had the highest prevalence of NG. In addition, the UU-CT co-infection pattern (7.32%) predominated in the study population, and CT was significantly associated with UU and NG. Conclusions: Our novel data demonstrated that UU, CT, and NG infection are prevalent among women in Taizhou, and comprehensive UU, CT, and NG screening guidelines and treatment policies for this population are warranted.
