Deregulation of the humoral immune response of the oyster (Crassostrea corteziensis) exposed to naphthalene

Summary:Naphthalene is one of the most abundant polycyclic aromatic hydrocarbons (PAH) in aquatic ecosystems, and it can cause alterations in the immune system of organisms that live there. The oyster Crassostrea corteziensis is a species native to the Eastern Tropical Pacific, with economic and ecological importance. In this study, we evaluated the effect of subacute exposure to sublethal concentrations of naphthalene on the parameters of the humoral immune response (lysozyme and phenoloxidase activity, and nitric oxide production) on the oyster C. corteziensis. The results indicated that naphthalene, under the conditions tested, significantly deregulated the parameters evaluated. This could increase susceptibility to infections and therefore affect oyster production.
