| first report of piscine nodavirus infecting wild winter flounder pleuronectes americanus in passamaquoddy bay, new brunswick, canada. | piscine nodaviruses (betanodaviridae) are frequently reported from a variety of cultured and wild finfishes. these non-enveloped, single-stranded rna virions cause viral encephalopathy and retinopathy (ver), also known as viral nervous necrosis (vnn) or fish encephalitis. recently, nodavirus infections have posed serious problems for larval and juvenile cultured halibut hippoglossus hippoglossus in norway and scotland. to date, no such viruses have been described from any cultured or wild pleuro ... | 2002 | 12078988 |
| taxonomy and host-specificity of gyrodactylus aideni n. sp. and g. pleuronecti (monogenea: gyrodactylidae) from pseudopleuronectes americanus (walbaum) in passamaquoddy bay, new brunswick, canada. | wild and cultured winter flounder pseudopleuronectes americanus (walbaum) from passamaquoddy bay were surveyed for species of gyrodactylus nordmann, 1832. two species were found: g. pleuronecti cone, 1981 and g. aideni n. sp, both members of malmberg's 'groenlandicus group'. although the hard parts in the haptor are very similar in the two species, hamuli of g. aideni are consistently shorter than those of g. pleuronecti. the two species differed by 35 base pairs in the its 1, 5.8 and its 2 regi ... | 2010 | 20960093 |
| molecular detection and characterization of nodavirus in several marine fish species from the northeastern atlantic. | nodaviruses (nnv) are responsible for causing disease outbreaks mainly in hatchery-reared larvae and juveniles of a wide variety of fishes throughout the world. this disease has seriously limited the culture of marine fishes over the last decade. in the atlantic provinces of canada, disease caused by a nodavirus was first reported in juvenile atlantic cod being reared in nova scotia, in 1999. more recently, disease outbreaks caused by nodavirus have been identified in hatchery-reared atlantic co ... | 2004 | 15672873 |
