Gut microbial shifts toward inflammation in Parkinson's disease: Insights from pilot shotgun metagenomics Egyptian cohort.

Abstract

Gut microbiome alterations are increasingly linked to Parkinson's disease (PD), yet regional signatures remain underexplored. We performed shotgun metagenomic sequencing of stool samples from Egyptian PD patients and healthy controls. PD patients exhibited depletion of short-chain fatty acid-producing taxa, and enrichment of pathobionts. Our findings suggested a pro-inflammatory gut shift in PD and emphasized the need for geographically diverse microbiome studies. While limited in sample size (n = 7 PD patients and n = 6 controls), this pilot addressed a critical gap in African PD microbiome research.
