Part of the School of Biosciences' new Autumn Biology Lecture Series. We are surrounded by microbes in, on and around us. Many are helpful or harmless whilst some cause well known infections. However, what is less appreciated is the way in which these invisible organisms influence aspects of our lives such as diet, allergies and even our behaviour. In this talk, we'll highlight some recent discoveries about the more unusual ways in which microbes make use of their human homes. Open to all who are interested in the study of Biology. Particularly suitable for A-Level students. The lectures are free of charge. All welcome to attend.
