Abstract
The presence of lysozyme activity was reported in the serum ofhealthy crayfish of four Astacidae species and two Cambaridae species. The kinetics curves were essentially similar, developing over a period of 1 hr at 30°C. Among the same species, important variability of the bacteriolytic activity was noticed between different animals. Repeated bleedings or increases in water temperature, lowered the serum lysozyme response. The lysozyme activity detected in serum after spontaneous coagulation and lysis of many hemocytes could represent a background of humoral defense activity, that is reduced by stresses known to weaken the crayfish.
