Chemotactic Activity of Hemocytes Derived from Two Marine Neritid Gastropod Molluscs, Nerita albicilla and Heminerita japonica, to Vibrio parahaemolyticus and Escherichia coli Strains

Abstract

Hemocytes of two marine neritid gastropods, Nerita albicilla and Heminerita japonica, were attracted chemotactically to live Vibrio parahaemolyticus and Escherichia coli strains. Chemotactic attraction of N. albicilla hemocytes was enhanced in the presence of TV. albicilla plasma, while that of H. japonica hemocytes was not enhanced in the presence of H. japonica plasma. Chemotactic activity of the hemocytes seems to participate in the rapid elimination of V. parahaemolyticus from these gastropods. © 1992, JAPANESE SOCIETY OF VETERINARY SCIENCE. All rights reserved.
