From: HPV infection and bacterial microbiota in the placenta, uterine cervix and oral mucosa
The bacterial microbiota in oral samples negative and positive for HPV DNA. Increased bacterial richness as assessed by the Chao1 index (A) was detected in HPV positive oral samples (blue) as compared to HPV negative samples (red). No difference in bacterial diversity (B) was detected between HPV negative (red) and positive (blue) oral samples. The relative abundance of bacteria are presented on the phylum (C) and family levels (D). In LEfSe analysis, unclassified Bifidobacteriaceae and Finegoldia genera were significantly enriched in HPV positive (blue) samples as compared to HPV negative (red) (LDA score > 3.36 and 3.32 respectively, p < 0.05), while Haemophilus genus was enriched in HPV negative (red) compared to HPV positive (E).
