First record of Tetracapsuloides bryosalmonae (Myxozoa; Malacosporea) in European whitefish (Coregonus lavaretus)

Proliferative kidney disease (PKD) is a temperature-dependent disorder of salmonids induced by the myxozoan parasite Tetracapsuloides bryosalmonae. In Europe, T. bryosalmonae has been reported in rainbow trout, Atlantic salmon, brown trout, Arctic char, brook trout and grayling. This study reports for the first time the presence of T. bryosalmonae in European whitefish (Coregonus lavaretus) while the parasite was not found in vendace (C. albula) and European smelt (Osmerus eperlanus).
