| genetic diversity and epidemiology of infectious hematopoietic necrosis virus in alaska. | forty-two infectious hematopoietic necrosis virus (ihnv) isolates from alaska were analyzed using the ribonuclease protection assay (rpa) and nucleotide sequencing. rpa analyses, utilizing 4 probes, n5, n3 (n gene), gf (g gene), and nv (nv gene), determined that the haplotypes of all 3 genes demonstrated a consistent spatial pattern. virus isolates belonging to the most common haplotype groups were distributed throughout alaska, whereas isolates in small haplotype groups were obtained from only ... | 2000 | 10843554 |
| isolation and characterization of a rhabdovirus from starry flounder (platichthys stellatus) collected from the northern portion of puget sound, washington, usa. | the initial characterization of a rhabdovirus isolated from a single, asymptomatic starry flounder (platichthys stellatus) collected during a viral survey of marine fishes from the northern portion of puget sound, washington, usa, is reported. virions were bullet-shaped and approximately 100 nm long and 50 nm wide, contained a lipid envelope, remained stable for at least 14 days at temperatures ranging from -80 to 5 degrees c and grew optimally at 15 degrees c in cultures of epithelioma papulosu ... | 2004 | 14769907 |
| differential susceptibility in steelhead trout populations to an emergent md strain of infectious hematopoietic necrosis virus. | a significant emergence of trout-adapted md subgroup infectious hematopoietic necrosis virus (ihnv) began in the coastal region of washington state, usa, in 2007. this emergence event lasted until 2011 and caused both asymptomatic adult fish infection and symptomatic epidemic disease and mortality in juvenile fish. incidence of virus during this emergence demonstrated a heterogeneous distribution among rivers of the coastal region, leaving fish populations of some rivers apparently untouched whi ... | 2014 | 25392039 |
| emergence of md type infectious hematopoietic necrosis virus in washington state coastal steelhead trout. | infectious hematopoietic necrosis virus (ihnv) occurs in north america as 3 major phylogenetic groups designated u, m, and l. in coastal washington state, ihnv has historically consisted of u genogroup viruses found predominantly in sockeye salmon oncorhynchus nerka. m genogroup ihnv, which has host-specific virulence for rainbow and steelhead trout o. mykiss, was detected only once in coastal washington prior to 2007, in an epidemic among juvenile steelhead trout in 1997. beginning in 2007 and ... | 2013 | 23759556 |
