Study of Spit Offers Insight Into Your Health – 480th Edition
Bacteria found in people’s spit does not vary much around the world, a report has surprisingly found. The experts believe this report could provide an insight into how diet and cultural factors affect human health.
As the human body carries 10 times more bacterial cells than human cells, scientists are trying to understand the findings and also understand more about the bacteria we carry in our mouths. The fact that people from varying cultures and regions can have the same basic bacteria within their mouths proves that we are all much more linked than we even previously thought. However, the other bacteria differs quite a lot which proves that our lifestyles may have a dramatic impact on the amount and types of bacteria in our bodies.
The human mouth is a major organ in the sense that it contains a diverse range of bacteria that reside in the mouth. However many scientists do not know anything about the bacteria we carry in our mouth, the diversity of this bacteria, how the bacteria effect us, how it relates to our diet and how it may hinder the process of us getting better when we are ill.
We are interested in this because by studying the bacteria we can get more insights into human populations than we would get from just studying the human DNA,” Mark Stoneking of the Max Planck Institute in Leipzig, Germany, the person who lead the investigation.
The research that was conducted on saliva samples from 120 people from volunteers from North America, South America, Western Europe, Eastern Europe, Africa and Asia.
The samples were taken from various different individuals so that the sample could be effective & also ensure that it was unbiased.
The team found that there was considerable diversity of bacterial life in the overall saliva microbiome with and between individuals. Within these samples from different geographic areas they did not find much variation, which tends to suggest that bacteria within a person in any of the countries could be just as different as someone on the other side of the world.
The findings could help better understand human migrations and populations. The results could also provide background for future investigations looking at the influence of diets, disease on differences in saliva as well as research further into how this is possible.
Mr M. Stoneking said “The saliva microbiome does not vary substantially around the world, which seems surprising given the large diversity in diet and other cultural factors that could influence the human salivary microbiome.”
