Scientists at the University of Cambridge discovered a type of gut bacteria called CAG-170 that is more common in healthy people. This bacteria helps with digestion and keeps the gut microbiome balanced.

Researchers from the University of Cambridge studied over 11,000 gut microbiome samples from people across 39 countries. They found that a specific group of gut bacteria, called CAG-170, was present in higher levels in healthy individuals. This bacteria is known only through its genetic signature and has not been grown in a lab before.

CAG-170 produces Vitamin B12 and carries enzymes that help break down carbohydrates, sugars, and fibers in the gut. The researchers believe that this bacteria helps maintain balance within the broader gut ecosystem by supporting other beneficial gut bacteria.

The study found that people with chronic illnesses like inflammatory bowel disease, obesity, and chronic fatigue syndrome had lower levels of CAG-170 bacteria in their gut. This suggests that CAG-170 could be a marker of gut microbiome health and may even be used to develop probiotics designed specifically to maintain healthy levels of this bacteria.

Dr. Alexandre Almeida, who led the study, said: 'Our work has revealed that CAG-170 bacteria appear to be key players in human health, likely by helping us digest our food and keep the gut microbiome running smoothly.'

Why It Matters

This research is important for Indian students because it highlights the importance of maintaining a healthy gut microbiome. A balanced gut microbiome can help prevent chronic diseases like inflammatory bowel disease and obesity, which are common in India.
