Microbiomes in far-flung places: characterizing the arctic Inuit gut microbiome

The hamlet of Resolute Bay is a tiny Arctic village in the Nunavut territory of Canada with a population that hovers at or below 300. Over hundreds of perhaps even thousands of years, the traditional Inuit diet in Resolute Bay and elsewhere has been dictated by the Arctic environment. The diet i... Read More

Researchers Use Innovating Methods to Study Vertical Transmission of Microbes

It has been assumed that mothers pass on gut microbes to their infants during and just after delivery, a process called vertical transmission, but because of technical restraints, the evidence of this occurring has been limited. Previous cultivation-free studies have observed the same microbial ... Read More
