Comparative Pathogenesis of P. marinus disease in bivalves: Development of Prevention Strategies for C. virginica
Principal Investigator:
Robert S. AndersonStart/End Year:
1997 - 2000Institution:
Chesapeake Biological Laboratory, University of Maryland Center for Environmental ScienceTopic(s):
Description:
To identify the basis of P. marinus pathogenicity to C virginica the following host-parasite interactions will be quantified in P. marinus susceptible and -resistant bivalves: phagocytosis and antimicrobial activity, effects of cellular and serum factors on parasite replication, and the production of host immunoregulatory molecules by P. marinus The in vivo effects of b-glucan, a stimulator of antimicrobial activity, administration will be evaluated on the progression and lethality of dermo disease.

Developing a habitat model for mysids, an important link in Chesapeake Bay food webs
Mysids are important mesozooplankton prey for many species of fish in Chesapeake Bay and are an important link in transferring energy from lower to upper trophic levels. Mysids also serve as biological vectors for benthic-pelagic coupling due to their diel vertical migration and omnivorous prey-switching behavior, which makes mysids important regulators of food web architecture. Despite their central role in coastal food webs, surprisingly little is known about mysid ecology and dynamics in Chesapeake Bay.
