This species belongs to the phylum Myxozoa, class Malacosporea, and causes proliferative kidney disease (PKD) in various species of salmonids (Anderson et al. 1999), which are found in Europe and North America, and can lead to severe losses in rainbow trout (Oncorhynchus mykiss) (Walbaum, 1792) and brown trout (Salmo trutta) (Linnaeus, 1758) farms. The associated economic losses due to this disease make it an important factor for aquaculture (El-Matbouli and Hoffmann 2002). Additionally, PKD is suspected of contributing to the decline of wild brown trout and salmon populations, especially in Switzerland (Wahli et al. 2002). Spores develop in the kidney tubules of infected fish and are released via urine to infect freshwater bryozoans (Grabner and El-Matbouli 2008). Proliferation of T. bryosalmonae induces granulomatous cellular response in the interstitial tissue which induces swelling of the kidney and spleen.
