 The study examined the salivary microbiomes of five adults over a period of up to 29 days. It used culture-independent methods to identify the presence of various bacterial species in the saliva. The results showed that the salivary microbiome was relatively stable over time, with certain species being present in all subjects at all time points. Additionally, some species were found to be unique to specific individuals, suggesting that the composition of the salivary microbiome may vary between people. This suggests that the salivary microbiome could potentially serve as a biological marker for identifying individuals. Furthermore, the study also identified a new genus of bacteria, gemella, which was present in all subjects at all time points. This suggests that gemella may play a role in maintaining the stability of the salivary microbiome. This article was authored by François Patrice, Anand S David, White Sun Catrine, and others.
