Objective: To identify the possible association between cervicovaginal infections (CVI) and preterm delivery.
Design: Cohorts. REFERENCE FRAME: Instituto Nacional de Perinatología, Hospital Central Militar and Hospital General Regional No. 1, IMSS, Culiacán, Sinaloa, México.
Patients: Four hundred and sixty eight patients attending prenatal control and delivery care.
Interventions: Fresh smears, Gram stain, and cervicovaginal sample culture from samples obtained during the following gestational stages: First sample at 16-24 weeks, second sample at 25-32 weeks, and third sample at 33-42 weeks. The following microorganisms were studied: Candida albicans, Gardnerella vaginalis, Ureaplasma urealyticum, Streptococcus agalactiae, Mycoplasma hominis, Neisseria gonorrhoeae, Listeria monocytogenes, and Chlamydia trachomatis. In case of a positive culture, the specific treatment was indicated.
Measurements: Positive or negative culture for each of the studied pathogens, and the presence or absence of a preterm delivery for each of the patients included in the study.
Results: Three hundred and ninety eight were still present at the end of the study, of which 156 had a CVI and 242 had no CVI. No differences between both groups were observed concerning preterm delivery. Significant relative risks were: In the first stage, Ureaplasma urealyticum and Mycoplasma hominis with RR = 9.0 (6.81, 11.8); in the second stage, Ureaplasma urealyticum with RR = 6.2 (3.30, 11.7) and Escherichia coli with RR = 3.4 (1.33, 8.6); in the third stage, Ureaplasma urealyticum with RR = 9.19 (6.93, 12.1). The logistic regression analysis identified Ureaplasma urealyticum during the second stage with OR = 16.6 (2.9, 93.7), statistically significant with p = 0.001. The survival analysis showed differences between the two groups concerning pregnancy duration (p < 0.001).
Conclusions: There is a difference in the duration in pregnancy in patients with CVI and without CVI. Ureaplasma urealyticum is consistently associated with preterm delivery.

Background: Human infection with is mainly manifested as non-gonococcal urethritis, where it can lead to cervicitis, premature rupture of membranes and abortion in women, as well as infertility in males, which becomes a major problem in clinical diagnosis and treatment. At present, real-time fluorescence quantitative PCR and culture are the two main methods for detecting UU. The real-time fluorescence quantitative PCR method is cumbersome and cannot accomplish absolute quantification on nucleic acids, while the cultivation method has limitations such as low sensitivity and being time-consuming.

Background: Sexually transmitted infections (STIs) rank among the most prevalent acute infectious conditions and remain a major global public health concern. Notable STI pathogens include Chlamydia trachomatis (CT), Ureaplasma urealyticum (UU), and Neisseria gonorrhoeae (NG). Early detection and diagnosis are crucial for controlling the spread of STIs.
