DGGE-based detection method for Quahog Parasite Unknown (QPX).
Quahog Parasite Unknown (QPX) is a significant cause of hard clam Mercenaria mercenaria mortality along the northeast coast of the United States. It infects both wild and cultured clams, often annually in plots that are heavily farmed. Subclinically infected clams can be identified by histological examination of the mantle tissue, but there is currently no method available to monitor the presen...
متن کاملDifferential Gene Expression in Five Isolates of the Clam Pathogen, Quahog Parasite Unknown (QPX).
Quahog parasite unknown (QPX) is a thraustochytrid protist that infects the hard clam, Mercenaria mercenaria, causing significant economic losses along the northeastern coast of North America. Previous investigations noted differences in growth dynamics and virulence in QPX cells from different geographic locations. In order to probe the molecular determinants for these variations, we investiga...
متن کاملEffect of environmental factors on survival and growth of quahog parasite unknown (QPX) in vitro.
Quahog parasite unknown (QPX) is a protistan microorganism associated with mass mortalities of hard clams (Mercenaria mercenaria) along the northeastern coasts of the United States and maritime Canada. Because several studies indicate modulatory effects of prevailing environmental parameters on disease outbreaks, this study tested the effect of major environmental parameters (temperature, salin...
متن کاملEffects of starvation and macroalgae extracts on the survival and growth of quahog parasite unknown (QPX)
Quahog parasite unknown (QPX) is a relatively poorly characterized protistan parasite that causes QPX disease in infected hard clams (Mercenaria mercenaria). Most prior studies presented descriptive reports of the occurrence and the characteristics of the disease in cultured and wild clams, while several basic aspects of the biology and ecology of the parasite remain obscure. In an attempt to b...
متن کاملIdentification and characterization of peptidases secreted by quahog parasite unknown (QPX), the protistan parasite of hard clams.
Quahog parasite unknown (QPX) is a protistan parasite capable of causing deadly infections in the hard clam Mercenaria mercenaria, one of the most valuable shellfish species in the USA. QPX is an extracellular parasite found mostly in the connective tissue of clam mantle and, in more severe cases of infection, other clam organs. Histopathologic examinations revealed that QPX cells within clam t...
