Study highlights association between oral bacteria and diseases

The study that I am toking about shows that the most common bacterial phyla amongst the samples were Firmicutes, Bacteroidetes, Proteobacteria and Actinobacteria, while the most common genera were Streptococcus spp, Prevotella spp, and Staphylococcus spp.

The study was conducted using 1,014 samples from as many patients, of whom 469 were women and 545 men.

The finding isn't only of importance to dental medicine, it also helps us understand the role of dental infection in patients with underlying diseases. If a certain bacterium infects and causes damage in the mouth, it's very likely that it can be harmful to tissues elsewhere in the body as the infection spreads.
