Vaginal microbiota of healthy pregnant Mexican women is constituted by four Lactobacillus species and several vaginosis-associated bacteria.

ABSTRACT:

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 we
