Italian Oral Microbiome

In forensics, research has aimed to exploit the variation in composition of the oral microbiome to answer forensic relevant topics, such as human identification and geographical provenience. Several studies have focused on the use of microbiome for continental, national, or ethnic origin evaluations. However, it is not clear how the microbiome varies between similar ethnic populations across different regions in a country. We report here a comparison of the oral microbiomes of individuals living in two regions of Italy, Lombardy and Piedmont. Oral samples were obtained by swabbing the donors oral mucosa, and the V4 region of the 16S rRNA gene was sequenced from the extracted microbial DNA.
