OBJECTIVE: To identify the microbiota communities in the vaginal tracts of healthy Mexican women across the pregnancy.
METHODS: Vaginal swabs were obtained during the prenatal visit of women from all trimesters (n = 64) of healthy pregnant women of Mexico City. DNA was isolated from each sample, and PCR-DGGE and sequencing of 16S rRNA gene fragments were used to identify the bacterial communities.
RESULTS: 21 different microorganisms were identified in the vaginal samples. Lactobacillus genus was present in 98% of women studied. Four lactobacilli species were identified in vaginal samples. L. acidophilus was the predominant (78%) followed by L. iners (54%), L. gasseri (20%), and L. delbrueckii (6%). 17 different microorganisms related to bacterial vaginosis conditions were identified. Ureaplasma urealyticum was the predominant (21%) followed by BVAB1 (17%) and Gemella bergeriae (7.8%).
CONCLUSIONS: Lactobacillus genus predominates in the vaginal samples of Mexican pregnant women associated with different microorganisms related to bacterial vaginosis conditions.
