A normal human gut virus, also called a bacteriophage, a country-specific bio-marker has been discovered. It is a benign globetrotter as the human himself. Further studies are keen on manipulating this microbiome to destroy harmful bacteria.
Travelling abroad for the summer can change a person's perspective--and it can also change the makeup of his gut.
Half the World's Population is Host to a Newly Discovered Gut Virus
A gut virus previously undetected by scientists, has been found to be present in more than half the world's population, found in a new study.

‘A normal human gut virus changes as the country that one has traveled to. But there is a global sameness of these viruses in the microbiome, and they are found to infect bacteria.’

A San Diego State University researcher has found evidence that a virus nicknamed crAssphage, found in the guts of about 70 percent of the world's population, has a country-specific biomarker that changes rapidly as humans travel from one location to another.
Bioinformatics researcher and professor Rob Edwards' study is the first to examine the global similarity of viruses in the human microbiome. His research also suggests that a relative of this crAssphage was living in primates and may have evolved alongside humans for millions of years. The research will be published in Nature Microbiology July 8th.

New computational modeling method can identify the microbe types in a person's gut which can reflect and affect the state of their health.
Edwards and colleagues discovered the existence of crAssphage in 2014 by using computer software rather than petri dishes to analyze fecal samples. This data-driven approach indicated crAssphage was not only "a benign globetrotter," but also "an integral part of the normal human gut virome."
He challenged the scientific community to join him in a kind of global treasure hunt for the virus, also called a bacteriophage. The response was overwhelming: 117 researchers, clinicians and academics together analyzed 32,273 different crAssphage sequences from more than 65 countries on six continents and found the phage, a type of virus that specifically infects bacteria, to be "a cosmopolitan inhabitant of the human gut the world over."
Key to this discovery were the worldwide scientific community of volunteers who helped make it happen by testing water from sewage plants, rivers, lakes, and ponds in their native countries.
Edwards said this recent discovery "is an illustration of how viruses move around the planet and are reflected in our microbiomes. We're just beginning to scratch the surface, but eventually, we may be able to manipulate the microbiome to target harmful bacteria. That would be a key step toward personalized medicine."
