Immune mechanisms in 2 strains of Salmo salar (Baltic salmon from River Ume Alv in Sweden and East Atlantic salmon from River Skjernå in Denmark) infected with the monogenean ectoparasite Gyrodactylus salaris were elucidated by molecular tools (real-time PCR). The gene expression in the fins (the preferred microhabitat of the parasite) of the susceptible but responding Swedish salmon was compar...

Assessment of contaminant impacts to federally identified endangered, threatened and candidate, and state-identified endangered species (collectively referred to as "listed" species) requires understanding of a species' sensitivities to particular chemicals. The most direct approach would be to determine the sensitivity of a listed species to a particular contaminant or perturbation. An indirec...

Vitellogenin (VTG) is a precursor of egg-yolk protein and is therefore present at high concentrations in the plasma of female fish. In male fish, VTG concentrations are usually undetectable or low, but can be induced upon exposure to oestrogenic substances either via the water or the diet. This work was carried out to determine the reason for apparently elevated VTG concentrations in unexposed ...

Most quantitative structure-activity relationship (QSAR) models are linear relationships and significant for only a limited domain of compounds. Here we propose a data-driven approach with a flexible combination of unsupervised and supervised neural networks able to predict the toxicity of a large set of different chemicals while still respecting the QSAR postulates. Since QSAR is applicable on...

A lethal effect of rainbow trout Oncorhynchus mykiss plasma containing intact complement factors on Gyrodactylus derjavini was demonstrated. It was associated with binding of complement factor C3 to certain carbohydrate-rich parasite structures. Parasites were exposed in vitro to plasma from rainbow trout. Untreated plasma from infected and uninfected fish showed lethal effects on the parasites...

In the present study, we describe the complete mitochondrial (mt) genome of the Atlantic salmon parasite Gyrodactylus salaris, the first for any monogenean species. The circular genome is 14,790 bp in size. All of the 35 genes recognized from other flatworm mitochondrial genomes were identified, and they are transcribed from the same strand. The protein-coding and ribosomal RNA (rRNA) genes sha...
