Recently, there has been a rapid increase in studies on the relationship between brain diseases and gut microbiota, and clinical evidence on gut microbial changes in Parkinson's disease (PD) has accumulated. 6-Hydroxydopamine (6-OHDA) is a widely used neurotoxin that leads to PD pathogenesis, but whether 6-OHDA affects gut microbial environment has not been investigated. Here we performed the 16S rRNA gene sequencing to analyze the gut microbial community of mice. We found that there were no significant changes in species richness and its diversity in the 6-OHDA-lesioned mice. The relative abundance of Lactobacillus gasseri and L. reuteri probiotic species in feces of 6-OHDA-lesioned mice was significantly decreased compared with those of sham-operated mice, while the commensal bacterium Bacteroides acidifaciens in 6-OHDA-treated mice was remarkably higher than sham-operated mice. These results provide a baseline for understanding the microbial communities of 6-OHDA-induced PD model to investigate the role of gut microbiota in the pathogenesis of PD.
