The effects of 2 injected bacterins, Vibrio damsela and Pasteurella piscicida 0-antigen bacterins, on the cell type composition of the peripheral blood and head kidney and on the phagocytic activity of the head kidney leucocytes were studied in turbot Scophthalmus maximus L. Blood and head kidney samples were collected from treated and non-treated turbot at different times in the 168 h period after injection. The number of neutrophils increased markedly in the peripheral blood of P. piscicida 0-antigen injected turbot 24 h after injection, being significantly higher (p < 0.01) than the neutroph~l number in V, damsela 0-antigen lnjected turbot. Forty-eight hours after injection, the numbers of head kidney neutrophils and macrophages in V. damsela and in P. piscicida 0-antigen injected turbot increased significantly (p < 0.05) compared with those in saline-injected turbot while the neutrophils in the peripheral blood decreased in fish treated with each of the vaccines. Turbot neutrophils have peroxidase-positive granules and also showed phagocytic capability. The phagocytic rate of the peripheral blood and head kidney phagocytes was higher in turbot injected with bacterins than in the saline-injected turbot, with the maximum phagocytic activity occurring 4 8 h after injection. Phagocytic activity of phagocytes in peripheral blood, kidney, and spleen was equal. Our data show that the phagocytes of turbot have a low phagocytlc affinity for sheep red blood cells in comparison to what has been reported for rainbow trout. Both V damsela and P. piscicida 0-antigen elicited a similar level of a non-specific immune response.

“…Peripheral blood neutrophils isolated from Japanese eels intraperitoneally injected with Edwardsiella tarda cells had significantly greater PRs and chemiluminescent response than those injected with saline; the peripheral neutrophils were also more active than those from the anterior kidney. It was concluded that the anterior kidney supplied the peripheral blood system (site of inflammation) with more mature and active neutrophils in response to the bacterial stimulation (Park & Wakabayashi 1992).…”

An experiment was conducted to determine the effect of Neoparamoeba sp. infection on the innate immune responses of Atlantic salmon. Atlantic salmon were experimentally infected with Neoparamoeba sp. and serially sampled 0, 1, 4, 6, 8 and 11 days post-exposure (dpe). Histological analysis of infected fish gill arches identified the presence of characteristic amoebic gill disease lesions as early as 1 dpe with a steady increase in the number of affected gill filaments over time. Immune parameters investigated were anterior kidney phagocyte function (respiratory burst, chemotaxis and phagocytosis) and total plasma protein and lysozyme. In comparison with non-exposed control fish basal respiratory burst responses were suppressed at 8 and 11 dpe, while phorbol myristate acetate-stimulated activity was significantly suppressed at 11 dpe. Variable differences in phagocytic activity and phagocytic rate following infection were identified. There was an increase in the chemotactic response of anterior kidney macrophages isolated from exposed fish relative to control fish at 8 dpe. Total protein and lysozyme levels were not affected by Neoparamoeba sp. exposure.

“…In vitro stimulation with phorbol esters also increases the integrin (CD18) expression by channel catfish head kidney neutrophils [3]. The peripheral neutrophils used in this study are expected to be up-regulated in their expression of integrin, following priming by injection of killed E. coli [19][20][21].…”
