Intraperitoneal vaccination of Atlantic cod, Gadus morhua with heat-killed Listonella anguillarum enhances serum antibacterial activity and expression of immune response genes
چکیده انگلیسی

Serum-mediated reduction in bacterial count and expression of a number of immune response genes in the blood of Atlantic cod, Gadus morhua were investigated following intraperitoneal vaccination with heat-killed Listonella (Vibrio) anguillarum. Blood was collected from the caudal vein of both vaccinated and non-vaccinated (PBS-injected) fish at 0, 1, 3, 7 and 10 days post-vaccination (dpv). Serum protein concentration and antibacterial activity of the serum samples were determined. Whole blood was used for semi-quantitative RT-PCR of immune-related genes. Total serum protein was not significantly different between the vaccinated and non-vaccinated groups. Sera from the vaccinated fish significantly reduced L. anguillarum count on 3 dpv, with reductions of at least 2 log colony forming units per ml (CFU/ml) relative to the non-vaccinated fish. Expression of antibacterial genes, bactericidal/permeability-increasing protein/lipopolysaccharide-binding protein (BPI/LBP), g-type lysozyme and transferrin was significantly upregulated in the vaccinated fish, with maximum expression within 7 dpv. Cytotoxic-related and cell-mediated immunity genes such as, apolipoprotein A-I and the non-specific cytotoxic cell receptor protein (NCCRP-1) had maximum expression at 3 and 7 dpv, respectively. Significant upregulation in expression of pro-inflammatory cytokines, IL-1β and IL-8 was also observed in the vaccinated fish at 1 dpv. The upregulation of immune response genes following vaccination provides valuable information in the understanding of immune mechanisms against vibriosis in Atlantic cod particularly on the acute phase response during bacterial infection.
