Growing body of evidence shows that our microbial population plays a role in health and disease. As the sequencing methods are rapidly developing and improving, it is essential to have state-of-the-art bio-informatic platforms and expert knowledge that allow for comprehensive visualization and biological interpretation of the massive datasets. Future studies focusing on microbiota interaction with the host and effect on animal host physiology, leave room for exploration and new discoveries within this dynamic field of research. Dr Sabina Lukovac from NIZO shows, how it will help to identify novel biomarkers and aid in development of new therapeutic strategies.
