New Publication on host-microbiota responses to heavy metal contamination (Video abstract)

The objective of this experimental microbial ecology and evolution study was to test the resilience of the microbiota in a host-microbiota system after exposure to a gradient of contamination with cadmium chloride.

MORE INFORMATION:

By combining modeling approaches for assembling ecological communities with network analyzes, we were able to quantify the contribution of the different evolutionary forces (neutral and non-neutral) to the taxonomic dynamics of the different microbial niches, as well as the interaction dynamics between the different members of microbial communities.

The novelty of this study suggests that the resilience tested on the yellow perch microbiota varies according to the type of tissue and the level of metal contamination: the skin microbiota has stabilized towards an intermediate structure, the intestinal microbiota has converged towards that of the group. control, suggesting strong resilience. The gradual contamination compared to the constant was more harmful on the composition and structure of all types of microbial communities, as well as on the bioaccumulation of Cadmium in the livers of juvenile fish.
