Microbiology Today May 19 | microbiologysociety.org 97 Editorial Welcome to the May edition of Microbiology Today, and up for investigation in this edition are microbial metabolism, health and disease. The ability of microbes to metabolise different substrates enables them to thrive in a vast diversity of niches, including various parts of the human host. The way microbes interact with metabolites influences how they affect the health of their host and can be linked to disease. This month our authors explore the fascinating range of ways in which these microbes and their metabolism can impact health. Whole Picture o start us off on this theme, Moving from bacteria to disease. Starting with the microbiome Kim Hardie reflects on how viruses, Sally Roberts and Joanna in early life and highlighting the factors T metabolism and the ability Parish consider how the development of that impact on the health of our to utilise essential nutrients forms organotypic raft cultures has improved microbiome, they consider the impact the basis of a healthy microbial cell. our ability to study virus infection of bacterial products on host health.
