The respiratory burst of leukocytes isolated from sea bass (Dicentrarchus labrax) pronephros, peritoneal cavity (P.C.), spleen and blood, was measured by a chemiluminescence (CL) assay after stimulation with beta-glucan. The CL response by P.C. and pronephros leukocytes was significantly higher than that expressed by a similar number of cells separated from spleen and blood. This probably reflects the observation that the proportion of macrophages and neutrophils was highest in the populations of leukocytes from peritoneal cavity and pronephros. Comparative observations showed a higher degree of yeast phagocytosis by leukocytes taken from peritoneal cavity than the pronephros. Moreover phagocytic index evaluated by microscopical observations, indicated that peritoneal macrophages internalised more yeast cells than neutrophils (identified by the peroxidase reaction). Scanning electron microscopy observations were also carried out. Inhibition experiments by a myeloperoxidase inhibitor sodium azide, iodonium-diphenyl-chloride which inhibits NADPH-oxidase, and exogenous superoxide dismutase, which catalyses O-2 dismutation to H(2)O(2), supported the correlation between CL and respiratory burst. Treatment with ouabain and DNP suggested that in this response, Ca(++) pump channels and calmodulin are involved in a metabolic energy-dependent pathway.
