The bacteria that affect human health
The bacteria found in saliva people are not vary greatly around the world, a surprising conclusion that could provide ideas on diet and cultural factors that affect human health, according to researchers.
Because the human body are 10 times more bacterial cells that human cells, scientists are trying to understand more about the bacteria that we have.
The human mouth is one of the main entrances of bacteria in the body and that contains a wide variety of microbial species, however, scientists know little about this diversity and how it relates to the diet, the environment, health and disease.
“We are interested in this because through the study of the bacteria can obtain more information on human populations” Mark Stoneking of Max Planck Institute in Leipzig, Germany, which led the study.
In his study published in the genome research, the team is in the sequence of bacteria taken saliva samples of 120 healthy volunteers in North America, South America, Western Europe, Eastern Europe, Africa and Asia.
To compare the samples from different geographical areas not found much variation, suggesting that the bacteria in the mouth of a person or the neighbor can only be as different as someone from the other side of the world. Read the rest of this entry »
