Editorial: The oral-gut axis: from ectopic colonization to within-host evolution of oral bacteria.

This article, titled "Editorial: The oral-gut axis: from ectopic colonization to within-host evolution of oral bacteria," explores the relationship between the oral and gut microbiomes and their impact on human health. The authors discuss the composition and dynamics of bacterial communities in the oral cavity and intestine, highlighting their roles in maintaining health and contributing to disease states such as inflammatory bowel disease (IBD) and colorectal cancer. The study also examines the crosstalk between oral bacteria and the immune system, as well as the potential link between the oral microbiota and Alzheimer's disease. Overall, the article provides valuable insights into the complex interplay between oral and gut microbiota and their implications for health and disease. [Extracted from the article]
