Abstract
Oysters, Crassotrea virginica, exposed to high concentrations (600 mg/l) of n-nitrosodiethylamine (DENA) during winter months (Feb. - May) showed significant enhancement of an epizootic apicomplexan parasite, Perkinsus marinus. The parasite reproduced and caused atypical pathosis in exposed oysters at water temperatures below its normal range (20 C). The reasons for this enhancement are not clear but may reflect damage to the oysters non-specific cellular immune system by the DENA.
