QPX is an emerging disease affecting cultured M. mercenaria from Atlantic Canada to Virginia. The major objective is to understand the hosts' defense responses to QPX. Specifically, a suite of hemocytic and serum-dependent immune mechanisms will be quantified and evaluated with regard to resistance to this protistan parasite. Parameters of immunity involved with non-self recognition, inhibition of replication, and killing of QPX organisms by circulating blood cells and serum macromolecules will be measured.
