With the development of next-generation sequencing methods, dysbiosis patterns of the vaginal microbiome have been described worldwide, but the correlation between dysbiosis and clinical symptoms, which is crucial for understanding the vaginal microbiome-host interaction, is largely unknown. The present study identified 4 types of community states in 88 women with vaginal dysbiosis. These community state types (CSTs) were dominated by non-iners Lactobacillus (CST1), L.iners (CST2), and Gardnerella vaginalis (CST3), and a variety of dominant species other than the above three (CST4). We found that urodynia or lumbodynia was more prevalent in women with CST4 than in women with CST3, and cervical hypertrophy was more prevalent in women with CST4 than in women with CST2 and CST3. These results indicate that patients in CST4 may have a greater tendency of vaginal symptoms, and the detailed mechanisms underlying these correlations of specific microbes with host symptoms should be further studied.
