PY - 2020 DA - 2020/06/15 TI - Impacts of a novel defensive symbiosis on the nematode host microbiome JO - BMC Microbiology SP - 159 VL - 20 IS - 1 AB - Bacteria adapted to live within animals can protect their hosts against harmful infections. Beyond antagonism with pathogens, a ‘defensive’ bacterial symbiont could engage in additional interactions with other colonizing micro-organisms. A single bacterium might thus have cascading ecological impacts on the whole microbiome that are rarely investigated. Here, we assess the role of a defensive symbiont as a driver of host-associated microbiota composition by using a bacterial species (Enterococcus faecalis) that was previously experimentally adapted to a nematode host model (Caenorhabditis elegans).
