The availability of next-generation sequencing, and the accompanying capability to process and analyze large amounts of data, has made many previously unthinkable projects possible. Examples include the sequencing of entire microbial genomes to track the spread of antibiotic-resistant infections in a hospital setting, sequencing all the contents of a particular foodstuff to identify meat sources and contaminants, and the microbiome project—a multi-national research effort to characterize the microrganisms colonizing the human body to look for associations with health and disease.
The ability to both get and process data on this large a scale has led to numerous advances in our understanding of the complex relationships between ourselves and our microbial colonizers. Over the last couple of years the microbiome project has generated data suggesting previously unimagined connections between bacteria colonizing our bodies and obesity, cardiac disease, and even personal identification.
As if the complex inter-relationship between bacterial and human cells isn’t enough to grapple with, there is also the virome to consider. Continue reading “Move Over Genome, Here’s the Virome”
