The main objective is to test the hypothesis that pollutant stress may predispose aquatic organisms to infectious diseases or accelerate the progression of the disease. The host-parasite system proposed is Crassostrea virginica - Perkinsus marinus; the environmental toxicants under study will include a lower MW polycyclic aromatic hydrocarbon (naphthalene) and tributyltin. An attempt will be made to associate pollutant-induced changes in disease progression to changes in cell-mediated immune function.
