MicroJC is back from winter holiday! We’re kicking off with a bang, with what could be a landmark paper in host-microbe community interactions. Within a host’s microbiome, each constituent can produce a multitude of metabolites. These metabolites create a chemical mosaic that interacts with other members of the microbiome and the host, which ultimately affects host fitness in a positive, neutral, or negative manner.
If microbiome composition can have a large impact on host fitness, wouldn’t it make sense for the host to shape its own microbiome to maximize fitness? So any animal may change its behavior to acquire certain microbes, much like you or I may choose to eat fermented food or probiotic yogurt. How then specifically do interactions between microbes affect animal fitness? In Elife this month, a group of researchers examine these critical questions by looking at metabolite exchange between microbial species and fruit fly feeding/egg-laying behavior. Join us on Friday, February 3rd at 3PM ET as we look at the first paper to connect these dots.
