dc.description.abstract <p>Studies of innate immunity in fish species of special concern are essential for better understanding of their health status during hatchery rearing conditions. The cytochemical and morphological characterizations of blood granulocytes have been used to provide information about phylogenetic differences and determine the potential use of neutrophil function assays. Rapid, simple, cytochemical staining kits used routinely for staining mammalian granulocytes have been used to characterize granulocytes from blood of four fish species: Arctic grayling, cutthroat trout, June sucker, and shovelnose sturgeon. Blood smears were stained with Peroxidase 391 (myeloperoxidase, MPO), alkaline phosphatase (AP), Periodic Acid Schiff (PAS) and Diff-quick stain; examined using bright field and differential interference contrast microscopy. Granulocytes on blood smears were evaluated based on the cell morphology, and presence or absence of the specific chromogen. Presence of lymphocytes, monocytes, platelets/thrombocytes and granulocytes was determined in all fish species. Arctic grayling, June sucker, and cutthroat trout had MPO positive granulocytes, while shovelnose sturgeon heterophils had positive reaction for leukocyte AP, but not MPO. Presence of MPO indicated potential to measure oxidative burst and degranulation of neutrophil primary granules in Arctic grayling, cutthroat trout and June sucker. Absence of MPO in shovelnose sturgeon suggested use of different enzyme marker (AP) in degranulation assay for this species. Standardization of cytochemical techniques allowed forrapid screening of leukocyte types, reducing the number of fish, time and effort to select adequate neutrophil function assays to be used in studies of health status in species of special concern.</p>
