“In conclusion, the Batwa exhibit higher diversity in their saliva microbiome composition. A number of unique genera are found only in the Batwa, and the lifestyle and diet of the Batwa may play a role in their distinctive saliva microbiome. Our results also highlight the importance of studying the microbiomes of non-traditional groups, in order to fully encompass the diversity of the human microbiome.”
This hunter-gatherer population has lower incidence of cavities. The investigators suggest this is because their diet affects the saliva microbiome which in turn prevents cavities. Makes sense. Interesting paper.
