Abstract

Objectives: To enable interactive visualization of the vaginal microbiome across the pregnancy and facilitate discovery of novel insights and generation of new hypotheses.

Material and methods: Vaginal Microbiome Atlas during Pregnancy (VMAP) was created with R shiny to generate visualizations of structured vaginal microbiome data from multiple studies.

Results: VMAP (http://vmapapp.org) visualizes 3880 vaginal microbiome samples of 1402 pregnant individuals from 11 studies, aggregated via open-source tool MaLiAmPi. Visualized features include diversity measures, VALENCIA community state types, and composition (phylotypes, taxonomy) that can be filtered by various categories.

Discussion: This work represents one of the largest and most geographically diverse aggregations of the vaginal microbiome in pregnancy to date and serves as a user-friendly resource to further analyze vaginal microbiome data and better understand pregnancies and associated outcomes.

Conclusion: VMAP can be obtained from https://github.com/msirota/vmap.git and is currently deployed as an online app for non-R users.

Keywords: 16S rRNA sequencing; bioinformatics; data integration; microbiome; visualization.

VMAP RShiny App. VMAP encompasses information from different microbiome studies gathering demographic information, birth outcomes, diversity measures, CST, and phylogeny (left). A user can visualize demographic features of the cohort, diversity measures (including correlations between them) by outcome of interest, alluvial plots of CSTs, dimensionality reduction plots of phylogeny, and heatmaps of taxonomical features (right). The visualizations are customizable by the filters in the bar on the left, allowing one to choose which projects and samples to visualize. Abbreviation: CST = community state types.
