1. Co-infections by multiple parasite genotypes are common and have
important implications for host-parasite ecology and evolution through
within-host interactions. Typically, these infections take place
sequentially and therefore, the outcome of co-infection may be shaped by
host immune responses triggered by previous infections. For example, in
vertebrates specific immune responses play a central role in protection
against disease over the course of life, but co-infection research has
mostly focused on previously uninfected individuals. 2. Here, we
investigated whether sequential exposure and activation of host resistance
in rainbow trout Oncorhynchus mykiss affects infection success and
interactions between co-infecting parasite genotypes of the trematode
eye-fluke Diplostomum pseudospathaceum. 3. In accordance with earlier
results, we show that a simultaneous attack of two parasite genotypes
facilitates parasite establishment in previously uninfected hosts.
However, we find for the first time that this facilitation in co-infection
is lost in hosts with prior infection. 4. We conclude that vertebrate host
infection history can affect the direction of within-host parasite
interactions. Our results may have significant implications for the
evolution of co-infections and parasite transmission strategies.
