This document summarizes the 3rd meeting of the international research group on infectious diseases and microbiology. The meeting discussed completing the gene repertoire of microorganisms by comparing genomes from environments, healthy humans, and patients to identify links to diseases. It was noted that current metagenomic studies have only identified 10-15% of organisms with ribosomes and 15-30% of known viruses. Tools discussed included using culture-introducing culturomics, genome sequencing and analysis. Specific results mentioned were related to giant viruses, the microbiota and obesity, causes of fever in Africa, and developing new culture media and vaccines.
