 This study examined the differences in gut microbiome composition between individuals with Parkinson's disease, PD, and those without it. It found that individuals with PD had different gut microbiomes than those without PD, suggesting that changes in a gut microbiome may be linked to the development of PD. Additionally, the study identified specific types of bacteria that were more prevalent in individuals with PD, suggesting that these bacteria may contribute to the development of the disease. This research provides insight into how the gut microbiome may affect the development of PD and could lead to new treatments for the disease. This article was authored by Bei Huang, Stephen W. H.
