Abstract

Bacterial vaginosis (BV) is a microbial imbalance (i.e., dysbiosis) that can produce serious medical effects in women at childbearing age. Little is known, however, about the incidence of BV or vaginal microbiota dysbiosis in pregnant teenagers in low and middle-income countries such as Ecuador. The scope of this exploratory analysis was to study the relationship between epidemiologic and microbial risk factors. Among the microbiology risk factors this study investigated fiveLactobacillusspecies, two of them know in preview studies as microbiology risk factors for BV development (Lactobacillus acidophilusandLactobacillus iners), and the last three known for being associated with a healthy vaginal tract (Lactobacillus crispatus,Lactobacillus gasseriandLactobacillus jensenii). In addition, fastidious anaerobes known to be microbial risk factors for BV development in pregnant teenagers were searched as well, more exactly,Gardnerella vaginalis,Atopobium vaginaeandMobiluncus mulieris. Ninety-five healthy adolescent pregnant women, visiting a secondary level hospital in Quito, Ecuador, were enrolled into the study in 2015. The enrolled patients were between 10 to 13 weeks of pregnancy. Four epidemiological risk factors were collected...Continue Reading
