Healthy body is not necessarily protected from bacteria. Even when your body is very clean, bacteria and chemicals will still be attached to the body. According to recent studies, in some particular body part has a collection of bacteria most. Quoted from the journal Proceedings of the National Academy of Sciences on Sunday (04/12/2015), originally scientists discovered there are 20 thousand chemicals and bacteria attached on the human body. Chemicals and bacteria comes from cosmetics, shampoos and deodorants. “These products are used in the body every day actually attached to the skin and a moisturizer handy become profitable,” said Pieter Dorrestein, professor of pharmacology at the University of California, San Diego.
The scientists start by rubbing a cotton research in 400 parts of the body on two volunteers who do not bathe and use any cosmetic products for three days. “We really want to see an increase in bacteria naturally from the body, so that we reduce the use of cosmetic products,” explains Pieter, who is also the leader of the study. Cotton is rubbed on the body and then analyzed by NMR and tools for analyzing DNA other bacteria. After that, the researchers could see a gathering place for the bacteria through the 3D image in every part of the body of volunteers. The result is amazing! It turns out the human body has a kind of bacteria and chemicals that are highly variable. Researchers identified about 850 different bacteria were also commonly found in food and medicine.
Even more interesting, the researchers found where bacteria are found at most in some parts of the body. Staphylococcus bacteria are found near the area of the foot, while Propionibacterium and Corynebacterium most volunteers come from both faces. Meanwhile apart in the intestine and vagina, Lactobacillus more visible in some parts of the body. But you do not need to panic, the bacteria attached on body has benefits that outweigh the costs. This discovery is expected to be renewed again to prevent diseases such as allergic porters, dermatitis and psoriosis. “Our team wanted to find out more about the bacteria in the body so that it can improve human health,” concluded Pieter.
