A recent study, led by Dr. Deanna L. Gibson from the Department of Biology at the University of British Columbia (Canada), has found that cardiorespiratory fitness is correlated with increased microbial diversity and increased production of faecal butyrate in healthy humans.

A recent study, led by Dr. Wendy A. Henderson from the National Institute of Nursing Research at National Institutes of Health (NIH) in Bethesda (USA), and co-authored by Research Fellow Dr. Nicolaas Fourie, has found that the oral microbiota could be a useful source of information in patients with irritable bowel syndrome (IBS).

Two recent studies, led by Dr. Veena Taneja from the Department of Immunology and Division of Rheumatology at Mayo Clinic in Rochester (USA), allow a better understanding of the role of gut microbiota in people with rheumatoid arthritis and how manipulation of the gut microbiota may provide an additional approach to therapy.

Recent advances in research have described the importance of gut microbiota in influencing interactions between the central and the enteric nervous systems. These brain-gut interactions appear to be bidirectional by means of neural, endocrine, immune, and humoral signals. Most of the data have been acquired using rodents (mice or rats) and pigs.

The gut microbiome of individuals with human immunodeficiency virus (HIV) is a topic of growing scientific interest, as recent research has linked severe immunodeficiency in HIV infection with changes in both the bacterial and viral communities of the gut.

A recent study, led by Dr. Yue Zeng from the Department of Gastroenterology at Shanghai Jiao Tong University School of Medicine in Shanghai (China), has found that colorectal pre-neoplasic lesions may be the most important factor leading to mucosal adherent bacterial dysbiosis in patients with colorectal adenomas.

A recent study, led by Prof. Maureen Hanson from the Department of Molecular Biology and Genetics at Cornell University in Ithaca, NY, USA, has found that ME/CFS patients have an altered composition of the gut microbiota that may play a role in increased microbial translocation and inflammatory symptoms in this condition.

It has been previously hypothesized that gut microbes could control a host’s eating behaviour through several potential mechanisms, including microbial manipulation of reward pathways, production of toxins that alter mood, changes to receptors (including taste receptors), and interference with neurotransmission via the vagus nerve—the main neural axis between the gut and the brain.
