That Gut Feeling

By studying the kinds and proportions of bacteria that live on and/or within you, the TCS team working on microbiome research can present a holistic picture of your present state of health, and even predict your future health condition

Most of us have experienced that strong gut feeling when trouble comes knocking at our door, although we are never quite able to explain exactly why (or how) we feel that way. What if we told you that there are bacteria in your gut that are capable of even stronger premonition – and that they could warn you about several impending diseases, including cancer?

The human body is home to a host of bacterial communities – or microbiomes – that together impact our overall health. By studying the kinds and proportions of bacteria that live on and/or within you, the TCS team working on microbiome research can present a holistic picture of your present state of health, and even predict your future health condition. Looking at certain biomarkers – that is, variations in structure or function – in these bacterial ecosystems, scientists can predict the presence or stage of several diseases. Some of these predictions could be life-saving.

The Life Sciences research area under TCS Research and Innovation (R&I), which specializes in the microbiome as one of the key topics of research, has for the past decade been developing and using state-of-the-art algorithms and analytics to examine the role of the human microbiome in diseases, and its applications in screening and diagnosis. While improved DNA sequencing technologies have made it possible for a large amount of bacterial genomic data to be sequenced, clinical interpretation of this data still remains a challenging task. This is where TCS researchers have achieved significant breakthroughs.

Analytics to the Rescue

The microbiome journey of this team started with an exploratory project in collaboration with the National Institute of Cholera and Enteric Diseases (NICED), Kolkata. NICED had collected gut microbiome data (that is, stool samples) from both healthy and severely malnourished children. The TCS team employed cutting-edge algorithms to decipher crucial insights about specific groups of bacteria that contributed to impaired digestion and poor nutrient absorption in the malnourished kids.
