| experimental infection dynamics: using immunosuppression and in vivo parasite tracking to understand host resistance in an amphibian-trematode system. | although naturally occurring hosts often exhibit pronounced differences in infection and pathology, the relative importance of factors associated with host life history and immunity in explaining such patterns often remains speculative. research in eco-immunology highlights the trade-offs between host physiology and immunity, for which natural variations in disease susceptibility offer a valuable platform to test predictions within this framework. here, we combined use of a novel, in vivo assay ... | 2013 | 23821713 |
| does timing matter? how priority effects influence the outcome of parasite interactions within hosts. | in nature, hosts are exposed to an assemblage of parasite species that collectively form a complex community within the host. to date, however, our understanding of how within-host-parasite communities assemble and interact remains limited. using a larval amphibian host (pacific chorus frog, pseudacris regilla) and two common trematode parasites (ribeiroia ondatrae and echinostoma trivolvis), we experimentally examined how the sequence of host exposure influenced parasite interactions within hos ... | 2013 | 23754306 |
