Host genotype and genetic diversity shape the evolution of a novel bacterial infection

Alice Ekroth & Kayla King
Pathogens continue to emerge from increased contact with novel host species. Whilst these hosts can represent distinct environments for pathogens, the impacts of host genetic background on how a pathogen evolves post-emergence are unclear. In a novel interaction, we experimentally evolved a pathogen (Staphylococcus aureus) in populations of wild nematodes (Caenorhabditis elegans) to test whether host genotype and genetic diversity affect pathogen evolution. After 10 rounds of selection, we found that pathogen virulence evolved to...
