Current research – gut bacteria, health and disease

In the last few years the role of gut bacteria, health and disease have become increasingly clear but there is still a lot to learn.

A lot of research is being carried out today in relation to the role of our gut ‘microbiome’ – the micro-organisms, bacteria, viruses, protozoa, and fungi, and their collective genetic material in each individuals gut. This research is mostly about how this is connected to health and disease, and in particular their interaction with genetics and the immune system in inflammatory bowel disease.
