中文摘要 | 本研究目的在於評估應用十一種不同聚醣類在大頭鏈及虱目魚體內是否可增加 對細菌之抵抗力。所使用的十一種聚糖類分別為Bar(萃取自Barely)、curdlan、Dex (dextran sulfate)、inulin、krestin、laminaran、levan、PO(萃取自Pleurouts ostreatus)、scleroglucan、YG(ueast glucan)、zymosan。結果顯示其中五種聚醣類:Bar 、curdlan、krestin、scleroglucan及zymosan均可使二種魚類對Aeromonas zymosan感 染之存活率有顯著性地增加(P<O.05)。然而,結果亦顯示僅其中四種聚醣類;Bar、 krestin、scleroglucan及zymosan可使二種魚類對Edwardsiella trada感染之存活率有顯 著性地增加(P<0.05)。為研究聚醣類激發魚體所產生之可能抗菌機制,嘗試以 NBT(nitroblue tetrazolium)吸附法來研究具有保護作用之五種聚醣類對魚隻吞噬細胞之影 響。結果顯示五種聚醣類:Bar、curdlan、krestin、scleroglucan及zymosan均可使二 種魚類產生02-的細胞數目增加。因此,增加魚類之非特異性吞噬細胞是聚醣類所激發其中的 一種抗菌機制。 |
英文摘要 | Efficacies of eleven polysaccharides including Bar (glycan extracted from Barely), curdlan, Dex (dextran sulfate), inulin, krestin, laminaran, levan, PO (glycan extracted from Pleurotus ostreatus), scleroglucan, YG (yeast glucan), and zymosan, in the protection of bighead carp, Aristichthys nobilis, and milkfish, Chanos chanos, against bacterial infections in vivo were examined. Five glycans, namely, Bar, curdlan, krestin, scleroglucan, and zymosan were observed to significantly increase the survival rates of bighead carp (70%, 40%, 40%, 70%, and 50%) and milkfish (50%, 40%, 40%, 60%, and 40%) (p<0.05) after challenge infection with Aeromonas hydrophial. However, only Bar, krestin, scleroglucan, and zymosan were found to significantly raise the survival rates of bighead carp (60%, 50%, 60%, and 60%) and milkfish (50%, 40%, 60%, and 50%) (p<0.05)after challenge with Edwardsiella tarda. Moreover, Bar, curdlan, krestin, scleroglucan, and zymosan were also found to significantly increase the number of cells stained positve with NBT (p<0.05) in the treated fish which indicate that activation of non-specific phagocytes may be one of the antibacterial mechanisms of polysaccharides. |
