Analysis of clotting defects in diseased lobsters—I. Alterations in blood parameters

Abstract 1. 1. In gaffkemic lobsters kept at 15°C. drastic declines in the hemocyte number and clotting ability occur. 2. 2. In animals kept at 10°C, although some clotting defects rapidly occur, a high number of amoebocytes is found. Clotting ability reappears after 5 days. 3. 3. The proportion of each type of hemocyte changes. Numerous hemocytes show morphologic altered features. 4. 4. Dorsal hematopoietic tissue is as in control lobsters. 5. 5. Total protein contents are similar in bacteremic or control lobster hemolymphs.
