Fig. 1From: Nisin a probiotic bacteriocin mitigates brain microbiome dysbiosis and Alzheimer’s disease-like neuroinflammation triggered by periodontal diseaseAnalysis of the microbial abundance by 16s rRNA sequencing shows that nisin reverses the changes in brain microbiome composition induced by oral polymicrobial infection. The groups included Control, Infection, Nisin, Infection + Nisin. Differential abundance analysis for bacteria at phylum (A) and genus level (B). *, the difference between the Control and Infection group was significant (P < 0.05). #, the difference between the Infection and Infection + Nisin group was significant (P < 0.05)Back to article page
