The balance of human intestinal microbiota, consisting of hundreds of bacterial species and phages (bacteria viruses), is crucial to good health. A research team, including scientists from the CNRS and the Institut Pasteur, has characterised the phage-bacterial interaction networks of the microbiota in ten healthy individuals, with unprecedented precision. Scientists detected several hundred bacterial and phage genomes and identified the thousands of interactions that bind them by quantifying the contacts between the DNA molecules of viruses and their hosts. This method has the advantage of providing exhaustive data from limited biological samples. The results were then analysed using algorithms similar to those applied to t ....
