I am not sure if this research relates to the biofilm life cycle (e.g., the the maturity of polymicrobial biofilms on human skin), but time will tell.
I salute the researchers for designing this experiment. I’d love to find out more. I will eventually listen to the podcast; source article and that found here:

Microbes Make Some People Smell Delicious To Mosquitoes
Tuesday, January 3, 2012
Ever wondered why mosquitoes eat some people up but leave others relatively unscathed? A new study finds that this preferential treatment is due to the smells produced by the microscopic critters that cover our bodies. The research is in the journal Public Library of Science ONE. [Niels O. Verhulst et al, Composition of Human Skin Microbiota Affects Attractiveness to Malaria Mosquitoes]
To a mosquito, every human has a particular smell. And the differences are due in part to the particular bacteria on each individuals skin.
The study tested the malaria-transmitting Anopheles gambiae mosquitos attraction to the odors of 50 adult men. The participants avoided items, such as garlic, that would change their natural smell.
Researchers collected the male scents by rubbing glass beads on the bottom of each participants foot, and swabbed the same skin for microbes. And they discovered that mosquitoes preferred the smell of skin with more abundantbut less diversebacterial communities.
The scientists suggest that the diverse communities may include some microbes that produce compounds mosquitoes naturally dislike. If further research can identify these compounds, it could lead to the development of repellents to make bloodthirsty mosquitoes buzz off.

Well!!According to me that skin is very sensitive part of the body.So we should be take care of the skin.According to me that vegetarian foods,milk and fresh fruits are
so good for keep good fitness of the skin.I am very care full abou the skin matters…
