140,000 viruses live in the human intestine |
Bacteriophage illustration.
Viruses are the most numerous organisms on the planet.
A paper published in Cell recently analyzed more than 28,000 gut microbiome samples collected in different parts of the world.
In the human intestine, in addition to bacteria, thousands of viruses called bacteriophages that can infect bacteria also live there.
This time, using a DNA research method called metagenomics, the researchers studied and recorded the diversity of virus species found in 28060 human intestinal metagenomics and 2898 bacterial isolated genomes, confirming that they live in the human intestine.
"Not all viruses are harmful.
Among the tens of thousands of viruses discovered, a new epidemic branch was discovered.
The two viruses seem to infect similar types of human intestinal bacteria, but the exact function of Gubaphage is not yet clear.
"An important aspect of our work is to ensure that the reconstructed viral genome is of the highest quality.
The research results form the basis of the intestinal phage database, which contains 142809 non-redundant phage genomes, which is a very valuable resource for those engaged in phage-related research.
