MJT Kibenge,T Iwamoto,Y Wang, A Morton, R Routledge and FSB Kibenge, (2016) Discovery of variant infectious salmon anaemia virus (ISAV) of European genotype in British Columbia, Canada.

This is the first published report of the detection of ISAV sequences in fish from British Columbia, Canada. The sequences detected, both of ISAV-HPRΔ and ISAV-HPR0 are of European genotype. These sequences are different from the classical ISAV segment 8 sequences, and this difference suggests the presence of a new ISAV variant of European genotype in BC. Our results further suggest that ISAV-HPRΔ strains can be present without clinical disease in farmed fish and without being detected by virus isolation using fish cell lines.
