The myxozoan, Tetracapsuloides bryosalmonae, is a multicellular endoparasite of freshwater bryozoans and salmonid fish.
Tetracapsuloides bryosalmonae causes the devastating Proliferative Kidney Disease in trout and salmon (Anderson et al. 1999; Canning et al. 1999; Feist et al. 2001), resulting in significant economic losses for aquaculture and threatening wild fish populations.
