Multiple introductions of salmonid alphavirus from a wild reservoir have caused independent and self-sustainable epizootics in aquaculture.


Salmonid alphavirus (SAV) causes infections in farmed Atlantic salmon and rainbow trout in Europe. Genetic diversity exists among SAV strains from farmed fish and six subtypes have been proposed based on genetic distance. Here, we used six full-genome sequences and 71 partial sequences of the structural ORF to estimate the evolutionary rate of SAV. The rate… (More)
