ODLADE SVAMPARS OCH BAKTERIERS FÖRMÅGA ATT AKTIVERA DET PROFENOLOXIDAS-AKTIVERANDE SYSTEMET FRÅN KRÄFTORS BLODKROPPAR / The Ability of Fungi and Bacteria to Activate the Prophenoloxidase Activating System from Crayfish Blood Cells
The immune defence of arthropods is specifically and efficiently turned on after infection with fungi or bacteria. Different proteins in the blood of the animal are activated by the addition of cell wall polysaccharides from these microorganisms, and the activation can be studied in vitro with commercial substrates that form coloured products after enzymatic reaction with these activated blood proteins. In the following work we have studied the activation of the arthropod blood proteins by bacteria or fungi, as in earlier studies mainly the purified cell wall sugars have been used for activation of these immune defence molecules.
