Photo by Fotciencia 2015

After a six-year-old boy placed his hand on a Petri dish and incubated for two days at 28°C, this photo was taken by Raúl Rivas González and Lorena Celador Lera. Their goal was to show children of this age that hand washing is important on the one hand, but on the other hand, the skin is inhabited by a large number of microorganisms. Behind these stains of different sizes and colors there are several species of bacteria and fungi.

Rivas and Celador have been the main winners of the 13th edition of Fotciencia, organized by CSIC and FECYT with this photo.
