Crohn’s disease is an inflammatory bowel disease linked to an imbalance in the gut microbiome. Now, researchers at McMaster University have found in mice a way to target and 'turn off' only the bad gut bacteria using specially trained, precision viruses. This breakthrough paves the way for treatments tailored to each patient.
Scientists discover that a gut microbiota molecule causes atherosclerosis

A new study reveals that a molecule produced by gut bacteria can trigger atherosclerosis, shedding light on why some healthy individuals develop cardiovascular disease.
A new stool biomarker for multiple sclerosis: gut bacteria’s role in disease progression
13 May 2025by Manon Oliero
New research suggests that changes in the ratio between two common gut bacteria could be associated with symptom severity in people with multiple sclerosis. While more studies are needed, the findings point to a potential microbial marker for monitoring the disease.
The gut-heart axis: how the gut microbiota impacts cardiovascular health
23 Dec 2024by Cristina Sáez
The fundamental role of gut bacteria in overall health has been recognized for years. Imbalances in its composition have been linked to autoimmune, gastrointestinal, and metabolic diseases, and now also to cardiovascular conditions. Increasingly, scientists are studying the gut-heart axis and suggest that the gut microbiota could become a new therapeutic target for preventing and treating heart diseases.
We continue our series on the gut axis, this time focusing on the gut-skin connection. You might have noticed it yourself—how a heavy, sugary meal can lead to breakouts the next day, or how certain food allergies can trigger rashes. This is the gut-skin axis at work, demonstrating an association between the health of our gut and the condition of our skin, and vice versa.
You are probably familiar with the gut-brain connection. But did you know that your gut and lungs are in constant conversation? Scientists call this connection the gut-lung axis. Both the gut and lungs are mucosal organs—while the gut absorbs nutrients from food, the lungs absorb gases like oxygen from the air.
Could the gut microbiota explain why inflammatory bowel diseases are on the rise?
23 Mar 2023by Andreu Prados
Inflammatory bowel disease covers chronic inflammatory conditions of the gastrointestinal tract, such as Crohn’s disease and ulcerative colitis. Find out more about the typical and atypical forms of IBD and what science knows about how the gut microbiota is involved in its development.
Allergic children present different bacterial strains that promote inflammation
21 Apr 2022by Manon Oliero
Rural living, vaginal delivery, pet ownership, eating a wide variety of foods, low antibiotic use, and breast milk microbiota can prevent your children from developing a respiratory or food allergy. But what if differences in the gut microbiota could predict which children will grow out of their allergies?
Will gut microbiota provide the solution to all of our health problems?
23 Apr 2020by Patrice D. Cani
Gut microbiota, with its close links to metabolism and the immune system, could potentially be a factor that lies at the core of good health. This means it can be positioned at the heart of the processes that influence the risk of contracting different diseases.
Have a look at our infographic to learn how a dysfunctional intestinal barrier may play a role in the development of gastrointestinal diseases.
