About 2000 Bacteria Has Been Discovered in the Human Gut

Researchers found almost 2000 bacteria in the human gut. The discovery was realized by researchers at EMBL’s European Bioinformatics Institute and the Wellcome Sanger. Almost 2000 bacteria are living in the human gut and these species are yet to be cultured in the lab.

Scientists used different kind of computational methods to analyse samples from individuals worldwide. The information was provided by the journal Nature, mentioning that though researchers are possibly getting closer to creating a comprehensive list of the commonly found microbes in the North American and European gut, there is a lack of data from other regions of the world.

“The human gut is home to many species of microbes, collectively referred to as the gut microbiota. Despite extensive studies in the field, researchers are still working on identifying the individual microbial species that live in our guts and understanding what roles they play in human health,” mentions www.sciencedaily.com.

“Computational methods allow us to understand bacteria that we cannot yet culture in the lab. Using metagenomics to reconstruct bacterial genomes is a bit like reconstructing hundreds of puzzles after mixing all the pieces together, without knowing what the final image is meant to look like, and after completely removing a few pieces from the mix just to make it that bit harder,” says Rob Finn, Group Leader at EMBL-EBI. “Researchers are now at a stage where they can use a range of computational tools to complement and sometimes guide lab work, in order to uncover new insights into the human gut.”

The study revealed how the composition of gut bacteria varies around the world, and how significant it is for the samples that researchers research to reproduce this diversity.

“We are seeing a lot of the same bacterial species crop up in the data from European and North American populations,” continues Finn. “However, the few South American and African datasets we had access to for this study revealed significant diversity not present in the former populations. This suggests that collecting data from underrepresented populations is essential if we want to achieve a truly comprehensive picture of the composition of the human gut.”
