Fig. 1From: Indoor bacterial, fungal and viral species and functional genes in urban and rural schools in Shanxi Province, China–association with asthma, rhinitis and rhinoconjunctivitis in high school studentsMicrobial taxonomic composition and NMDS analysis of taxonomic composition in high schools in Shanxi, China. A The taxonomic composition is presented as the relative abundance of major microbial classes. Schools 1–5 are from rural areas, and schools 6–10 are from urban areas. B NMDS ordination of the classroom microbiome was calculated based on the Bray-Curtis distance matrix. Ordination plot between axes NMDS1 and NMDS2 is shownBack to article page
