Comparison of Amish and non-Amish oral microbiomes

What is it about?

This research compares the oral bacteria of the Old-Order Amish to rural non-Amish. Our findings demonstrate that the Amish have bacteria in their mouth (i.e., associated with saliva and plaque) that are distinctly different than non-Amish. The more diverse mix of species and a noticeably lower amount of one specific grouping of bacteria (Proteobacteria) in the Amish may be because of differences in genetics, lifestyles, diet, and dental habits.

Why is it important?

This study was an exploratory study consisting of saliva and plaque samples from 14 Amish and 13 non-Amish individuals. While quite a bit is known about non-Amish individuals living in Lancaster County, PA, this study is the first to characterize the oral microbiome of Amish living in close geographic proximity. The study findings demonstrate that both groups have the same general types of bacteria in their mouths, but that lifestyle, diet, genetics, and dental habits can also yield differences in the bacterial communities,
