Omics in the research of chloramine treatment against parasite infestation

February 18, 2021 Off

The monogenean salmon fluke (Gyrodactylus salaris) is a dangerous ectoparasitic pathogen for Atlantic salmon (Salmo salar) and frequently occurs in Norwegian rivers. High infection rates have reduced populations of salmon parr and led to a decline of upstream-swimming adult fish. Thus, finding efficient measures for the eradication of the parasite is necessary. The treatments that…

New project on fish-killing algae and their toxins funded by The Research Council of Norway

February 8, 2021 Off

Algal blooms are seasonal phenomena in marine and freshwater ecosystems. Their frequency and severity are increasing, at least in part because of human impact. Algal blooms may be harmful (so-called HABs) and result in the die-off of vertebrate and invertebrate species. The reason for such mortality events can be variable and complex, and may include…

The Fusarium mycotoxin AOD makes big vacuoles in the cells

April 2, 2020 Off

In this newly published paper we have investigated cellular effects of the Fusarium mycotoxin 2-Amino-14,16-dimethyloctadecan-3-ol (AOD). AOD were found to induce big transient vacuoles in the cells. The effect were observed at non-toxic concentrations and not linked to any cell death processes. A detailed study further revealed that the vacuolization is due to an accumulation…

A Practical ELISA for Azaspiracids in Shellfish and Algae

February 21, 2019 Off

Azaspiracids (AZAs) are a group of natural algal toxins that appear periodically in shellfish. These toxins can cause food poisoning in humans and the first known poisoning episode happened in The Netherlands in 1995. The Irish shellfish consumed gave symptoms like stomach cramps, vomiting, severe diarrhea, and general nausea. Current methods for quantifying the regulated…
