SUMMARY Climate change, in particular rising temperature, is suspected to be a major driver for the emergence of many wildlife diseases. Proliferative kidney disease salmonids, caused by myxozoan Tetracapsuloides bryosalmonae , was used evaluate how temperature dependence host–parasite interactions modulates emergence. Brown trout ( Salmo trutta fario ) kept at 12 and 15 °C, were experimentally infected with T. . Parasite development fish host release spores quantified simultaneously unravel parasite transmission potential from vertebrate invertebrate host. A change stable plateau infection intensity coincided threshold which spore shedding commenced. This onset delayed low accordance reaching this threshold, but amount released irrespective temperature. The production stages declined time. In conclusion, elevated modifies opportunities increasing duration stage production, may affect spread establishment wider range rivers.
