Standardized challenge models will be developed with viral, bacterial, parasitic agents with expected importance for gill disease, as well as with planktonic agents like algae and diatoms, and zooplankton (such as jellyfish and siphonophores). The agents to be involved in these trials include the amoeba Paramoeba perurans, the bacterium Branchiomonas cysticola, and poxvirus. Cultivation of these agents in vitro for challenge purposes will be emphasized, and they will also be subjected to more detailed genetic characterization. Potentially harmful phytoplankters will be included, such as Chaetoceros sp. and Alexandrium sp., or jellyfish like Aurelia auritaor Periphylla periphylla.
The effects of challenge will be studied in trials with one agent alone, or more agents in combination. Parameters to be measured include respiratory and cardiovascular responses, and effects on blood chemistry, acid-base balance and electrolyte levels. Histopathological changes will be evaluated by implementing a new gill scoring system based on a totality of cellular and epithelial abnormalities. The detection of relevant gill associated microbial agents will be included.
