Abstract: Many animal and plant species harbour microbes in their microbiota that suppress pathogen infection. These ‘protective microbes’ can form a significant component of host defence. By experimentally evolving multiple microbial systems (e.g., worms, bacteria, viruses), my group has demonstrated that host-associated microbes can rapidly evolve to defend their animal hosts against infection. We show these protective microbes can drive major changes in molecular processes underlying pathogen virulence and host immunity, as well as alter host-pathogen coevolutionary dynamics and evolutionary rates. Our results indicate that microbes in hosts are important in shaping infection outcomes, during pathogen emergence and over evolutionary time.
