Characteristics and potential diagnostic ability of vaginal microflora in patients with aerobic vaginitis using 16S Ribosomal RNA sequencing.

PURPOSE: We aimed to explore the possible function of guiding dominant microflora for aerobic vaginitis (AV) women patients in China to know its diagnostic ability for the further clinical application.

METHOD: The characteristics and community compositions of AV vaginal microbiota was evaluated by high-throughput 16S ribosomal RNA (16S rRNA) sequencing after the vaginal microecology evaluations.

RESULTS

The increased colonization of Streptococcus agalactiae and Streptococcus anginosus and the absence of Lactobacillus are typical manifestations of AV patients. In addition, Lactobacillus were the major correlated bacteria with control groups of Modified Donders' Score under 3. Most of the significant KEGG pathways were classified into metabolism pathway, where the two bacteria behaved their own metabolism characteristics.

CONCLUSION

The increased colonizations of Streptococcus agalactiae and Streptococcus anginosus and the absences of Lactobacillus are the typical manifestations of AV.
