“…With an estimated annual prevalence of 276 million new cases, mixed infections with different parasite strains are expected. Although it is known that parasites interact with their host to enhance their own survival and transmission, evidence of mixed infections call into question the extent to which unicellular parasites communicate with each other. …”

“…Coevolution between hosts and parasites is a major driver of rapid evolutionary change(1) and diversification.(2)(,)(3) However, direct antagonistic interactions between hosts and parasites could be disrupted(4) when host microbiota form a line of defense, a phenomenon widespread across animal and plant species.(5)(,)(6) By suppressing parasite infection, protective microbiota could reduce the need for host-based defenses and favor host support for microbiota colonization,(6) raising the possibility that the microbiota can alter host-parasite coevolutionary patterns and processes.(7) Here, using an experimental evolution approach, we co-passaged populations of nematode host (Caenorhabditis elegans) and parasites (Staphylococcus aureus) when hosts were colonized (or not) by protective bacteria (Enterococcus faecalis). …”
