From: Characteristics of bacterial community in eyelashes of patients with Demodex blepharitis
Alpha diversity and beta diversity. a–e Violin plot of alpha diversity based on diversity indexes: a Chao1 index, b Good’s Coverage index, C Observed OTU index, d Shannon index, e Simpson index (P > 0.05, Mann–Whitney U-test). f Beta diversity PCA. The distance between samples from the two groups was close, and no obvious separation trend was observed (P > 0.05, ANOSIM test). The red part of the diagram represents the control group (eyelashes from healthy volunteers); the blue part of the diagram represents the DB group (eyelashes from patients with Demodex blepharitis). C, Control group; PCA, principal component analysis; T, DB group
