| piscine reovirus: genomic and molecular phylogenetic analysis from farmed and wild salmonids collected on the canada/us pacific coast. | piscine reovirus (prv) is a double stranded non-enveloped rna virus detected in farmed and wild salmonids. this study examined the phylogenetic relationships among different prv sequence types present in samples from salmonids in western canada and the us, including alaska (us), british columbia (canada) and washington state (us). tissues testing positive for prv were partially sequenced for segment s1, producing 71 sequences that grouped into 10 unique sequence types. sequence analysis revealed ... | 2015 | 26536673 |
| piscine reovirus, but not jaundice syndrome, was transmissible to chinook salmon, oncorhynchus tshawytscha (walbaum), sockeye salmon, oncorhynchus nerka (walbaum), and atlantic salmon, salmo salar l. | a jaundice syndrome occurs sporadically among sea-pen-farmed chinook salmon in british columbia, the westernmost province of canada. affected salmon are easily identified by a distinctive yellow discolouration of the abdominal and periorbital regions. through traditional diagnostics, no bacterial or viral agents were cultured from tissues of jaundiced chinook salmon; however, piscine reovirus (prv) was identified via rt-rpcr in all 10 affected fish sampled. by histopathology, jaundice syndrome i ... | 2016 | 25630226 |
| piscine reovirus in wild and farmed salmonids in british columbia, canada: 1974-2013. | piscine reovirus (prv) was common among wild and farmed salmonids in british columbia, western canada, from 1987 to 2013. salmonid tissues tested for prv by real-time rrt-pcr included sections from archived paraffin blocks from 1974 to 2008 (n = 363) and fresh-frozen hearts from 2013 (n = 916). the earliest prv-positive sample was from a wild-source steelhead trout, oncorhynchus mykiss (walbaum), from 1977. by histopathology (n = 404), no fish had lesions diagnostic for heart and skeletal muscle ... | 2015 | 25048977 |
