The skin that attract mosquitoes more
For insects, some people are more "teaser" than others. The variety and amount of bacteria on the skin, key to the "pull" of mosquitoes.
Researchers at the University of Wageningen, The Netherlands, discovered why some people are more "attractive" than others to mosquitoes: the variety and amount of bacteria on the skin can attract these insects. The experts conducted their experiments with female mosquitoes Anopheles gambiae species, which is key in the transmission of malaria in Africa. For chopping, the mosquitoes are guided by signals from the skin fragrant, produced by microbes. The researchers wanted to determine if the composition of the microorganisms on the skin, called microbiota, affects the degree of attraction is a mosquito to a human being. They found that the skin of the feet produces compounds that are attractive to A. gambiae and this is one of the favorite snacks. So, who are more communities of bacteria in the feet, have more chances of being bitten.
