Morphology and Migratory Activity of Hemocytes of Heminerita japonica

Abstract

Hemocytes of Heminerita japonica were found to be amoebocytes. The hemocytes migrated chemotactically to H. japonica serum in low level. Chemokinesis of the hemocytes was also observed in 20% serum. The hemocytes migrated to a suspension of Vibrio parahaemolyticus strain D-3. The migration to the bacterium was not stimulated in the molluscan serum. From these evidences, the hemocytes are suspected to participate in the clearance of the bacterium from H. japonica.
