An ambitious,first-of-its-kind study on gut flora (microbes) in the Indian population clearly shows that the microbes could well be different from that found in the Western population. The findings detected some new bacteria implying that the link between gut flora and certain diseases in the West may not hold true for Indians.
The study has been accepted for publication in BioMedCentral (Microbiology).
Microbes in our gut play a huge role in overall health, says Shouche. Trillions of bacteria present in the gut help break down foodstuffs that our cells are not capable of doing…our knowledge of these microbes is largely limited, Shouche said.
The researchers collected stool samples from generations of two Pune-based families.
An eight-month-old infant,a 26-year-old and a 56-year-old,all of them male,of one family,and a 14-year-old,a 42-year-old and a 62-year-old,all female,from another family were involved in the yearlong study.
It is a miniscule sample size but the first such attempt is significant as here we also observed that gut flora changes with age, says Shouche.
After isolating anaerobic bacteria from stool samples,researchers found that 30 per cent of the bacteria isolated was entirely new,a finding not been reported anywhere in the world,suggesting that Indian individuals harbour novel bacteria,says Shouche.
Modern techniques like DNA sequencing and and qPCR were used in the study. We observed that gut flora changes with age within members of the same family. Different bacteria were dominant in gut flora of individuals with varying age, Shouche said.
