One of the first critical steps in pathogenesis amoebic gill disease (AGD) farmed salmon is adhesion causative amoeba to host. The current study aimed investigate potential involvement glycan-binding proteins expressed on extracellular surface Neoparamoeba perurans tissue recognition and binding. properties membrane N. carbohydrate binding profile Atlantic gill-derived epithelial cells were ide...

Amoebic gill disease (AGD) is the most important parasitic disease of Atlantic salmon industry inAustralia. Atlantic salmon (Salmo salar) experimentally infected with Neoparamoeba sp. apparently showedAGD gross signs on the gill and an amoebic-associated gill pathology. Physico-chemical factors of waterduring the experiment were monitored regularly and were approximately constant (temperature: ...

Legionella pneumophila proliferates in aquatic habitats within free-living protozoa, 17 species of which have been identified as hosts by using in vitro experiments. The present study aimed at identifying protozoan hosts for L. pneumophila by using a biofilm batch test (BBT). Samples (600 ml) collected from 21 engineered freshwater systems, with added polyethylene cylinders to promote biofilm f...

The increasing economic importance of fish parasitoses for aquaculture and fisheries has enhanced the interest in the defence mechanisms against these infections. Both innate and adaptive immune responses are mounted by fish to control parasite infections, and several mechanisms described for mammalian parasitoses have also been demonstrated in teleosts. Innate immune initiation relies on the r...

19 Daily variation in the absorption, metabolism and excretion of toxic substances will 20 ultimately determine the actual concentration to which the cells and tissues are exposed. In 21 aquaculture, Atlantic salmon (Salmo salar) can be frequently exposed to hydrogen peroxide 22 (H 2 O 2) to treat topical skin and gill infections, particularly in relation to parasitic infections 23 (e.g. sea li...
