There may be a new way to distinguish a person’s identity.
Bacteria in the mouth—especially bacteria located in gums—can tell you more about a person then could ever be imagined. The remnants are similar to that of a fingerprint, meaning it’s possible to tell some people apart based on these remnants. And yes, you can even tell a person’s ethnicity.
Scientists managed to pinpoint 400 different species of bacteria in the mouth based on about 100 participants in the study. The ethnicities involved included blacks, whites, Chinese and Latinos.
The results indicated that just 2 percent of bacterial species are seen in all people. The exact numbers, high or low, showed some similarities among people of the same ethnic group.
