Objective:

To determine the prevalence of potentially pathogenic microbiological agents in vaginal exudates in a sample of asymptomatic pregnant women in the Department of Atlantico, Colombia.

Materials and Methods:

Descriptive cross-sectional study of a sample of asymptomatic pregnant women who attended a private primary healthcare institution in Barranquilla, Colombia, between 2014 and 2015. Pregnant women having received antimicrobial treatment within the last 30 days, with vaginal bleeding, mental disability or immunosuppression, were excluded. Consecutive sampling was performed. The prevalence of colonization time by some of the microbiological agents as well as specific prevalence were estimated: number of women with infection by agent type/number of women at risk assessed.

Results:

Overall prevalence was 24.8% (56/226); 55.4% (31/56) was due to vaginitis causal agents, and 44.6% (25/56) to vaginosis. The specific prevalence by type of pathogen, 13.3% (30/226) was vaginitis due to colonization by Candida spp. and 0.4% (1/226) was vaginitis due to T. vaginalis. Bacterial vaginosis (BV) was found in 8.0% (18/226).

Conclusion:

Substantial colonization of the lower genital tract by potentially pathogenic germs is found in pregnant women between 35 and 37 weeks of gestation. Further studies are required in order to determine the benefit of population screening in terms of avoiding poor maternal and perinatal outcomes, and the impact on the resulting overcosts.
