Occurrence of Tetracapsuloides bryosalmonae in the kidney of smolts of Atlantic salmon (Salmo salar) and sea trout (S. trutta)

Out-migrant smolts from a river on the west coast of Norway were sampled prior to seawater entry and screened for the occurrence of Tetracapsuloides bryosalmonae by histology and real-time PCR. T. bryosalmonae was found in more than 50% of the fish by real-time PCR, while no exstrasporogonic stages...

Zusammenfassung:Out-migrant smolts from a river on the west coast of Norway were sampled prior to seawater entry and screened for the occurrence of Tetracapsuloides bryosalmonae by histology and real-time PCR. T. bryosalmonae was found in more than 50% of the fish by real-time PCR, while no exstrasporogonic stages were found by histology. Heavily melanization in the kidney tissue was found in less than half the examined which could be the result of a past or ongoing subclinical PKD or caused by other infections.
