They find 2,000 new bacteria in the human gut

Scientists from the European Laboratory of Molecular Biology (EMBL) and the Wellcome Sanger Institute (UK) identified nearly 2000 species of bacteria that inhabit the human bowel. The advance, published in Nature, was possible thanks to powerful computer techniques that allowed the genomes to be identified, the many genes of these organisms.

"Calculation methods allow us to understand the bacteria that we can not grow in the lab yet," said Rob Finn, head of the EMBL research team.

Although technology does not allow these microbes to grow in laboratories or be analyzed, computer sciences and sequencing methods (meta-genomics) allow them to organize and read their genomes accordingly. That's why species that have not yet been spotted.

"Using meta-genomics to reconstruct bacterial genomes is like restoring hundreds of puzzles after mixing all the pieces without knowing how the final image will look and after removing a few pieces forever to make the work a little bigger . Finn said.

Despite the difficulty of this task, researchers now have powerful computer techniques to learn about the secrets of the microbial world and especially microbes.


Map of microbes. Scientists are closer to creating a complete map of all germs that are usually part of the intestines of people in North America and Europe.

Microorganisms. So far, it is known that intestinal microorganisms play a crucial role in preventing pathogens from entering, regulating the immune system and absorbing nutrients.
