Abstract:The Flavobacterium odoratum extracellular glycoprotein, prepared with sea water culture media and by centrifugalizing, fertilyzing and filtrating, was injected into fresh water crayfish Procambarus clarkii at the intercoxal region between the first and second abdominal segment. Then, their blood-lymph was taken out every day, and the activities of lectin, phenoloxidase(PO), bacteriolysis and antibacteria in the serium and the bacteriolysis, antibacteria and SOD in the muscle were analysed. The results show that the activities of all the above immune factors in serum in test groups are higher than those in control, with lectin activity maintaining at the maximum level within day I to day 4 after the injection, PO activity remaining high within day I to day 4 and reaching highest on the second day. SOD, bacteriolysis and antibacterial activities in the muscle between test and control groups have no evident differences. It comes to the conclusion that the glycoprotein of F. bacterium is able to stimulate activities of lectin, phenoloxidase, bacteriolytic and antibacterial in blood-lymph of crayfish.
Keywords:Flavobacterium odoratum  glycoprotein  Procambarus clarkii  lectin  phenoloxidase  bacteriolysis  antibacteria  superoxidase dismutase
