| qualitative risk assessment of routes of transmission of the exotic fish parasite gyrodactylus salaris between river catchments in england and wales. | gyrodactylus salaris is a freshwater, monogenean ecto-parasite of atlantic-salmon. infection of its natural host, the baltic strain of atlantic-salmon, is inapparent. g. salaris also can infect rainbow-trout (oncorhynchus mykiss) permanently, and cause infection of < or =50 days in several other species. it is only on atlantic stocks of atlantic-salmon (salmo salar) that the parasite multiplies unchecked by an immune response, causes death in juveniles and dramatic reductions in wild populations ... | 2004 | 15325771 |
| mitochondrial haplotype diversity of gyrodactylus thymalli (platyhelminthes; monogenea): extended geographic sampling in united kingdom, poland, and norway reveals further lineages. | in recent years, the mitochondrial haplotype diversity of the monogenean ectoparasites gyrodactylus salaris malmberg, 1957 on atlantic salmon and g. thymalli zitnan, 1960 on grayling has been studied intensively to understand the taxonomy and phylogeography of the two species. according to these studies, neither species can be considered monophyletic, but unfortunately, the geographic sampling has mostly been restricted to fennoscandia. only few samples from continental europe have been analysed ... | 2007 | 17216240 |
