Epitheliocystis Distribution and Characterisation in Brown trout (Salmo trutta) from the headwaters of two major European rivers, the Rhine and Rhone.

We present a first description of the distribution and characterization of epitheliocystis infections in brown trout (Salmo trutta) from the upper catchments of two major European rivers, the Rhine and the Rhone. Overall, epitheliocystis was widely distributed, with 70% of the Rhine and 67% of the R...
