Vertically and horizontally transmitted microbial symbionts shape the gut microbiota ontogenesis of a skin-mucus feeding discus fish progeny
Scientific Reports 7:5263 (2017)
This new publication, authored by François-Étienne Sylvain and Nicolas Derome, discusses the gut microbiota acquisition patterns in the Discus fish, which display a unique parenting behaviour by feeding their fry off their own skin mucus in the early life stages.

Northern ecosystems are facing unprecedented assaults resulting from direct (e.g. industrial activities, such as mining and hydroelectricity) and indirect (global warming) anthropogenic activities, thus amplifying the risk of disturbing essential ecosystem services mediated by microbial communities (nitrogen cycle, primary production) and contaminate the whole food web. Because gut microbiota is critically implicated in modulating the host response to contaminants and toxins, such bio-accumulated contaminants (e.g. iron, mercury, arsenic, lead, cadmium, arsenic and manganese) are expected to have serious consequences on major host functions such as immune response, energetic performance and development. Furthermore, there are enough results suggesting that climate change could alter stages and rates of development of endemic pathogens, modify host resistance, and result in changes in the physiology of host-pathogen interactions. Because microbiota constitutes the first immune barrier by both producing specific antimicrobial compounds and outcompete invasive microbes for host resources, it is crucial to develop a sentinel model for studying skin and gut microbiota resilience when facing allochthonous pathogens in controlled conditions.
