Cytotoxicity of quahog parasite unknown (QPX) toward hard clam ( Mercenaria mercenaria) haemocytes and interactions between different pathogen isolates and host strains.
The ability of pathogens to neutralize host defence mechanisms represents a fundamental requisite in the successful establishment of an infection. Host-pathogen interactions between quahog parasite unknown (QPX) and its hard clam host are poorly understood. Our prior in vivo investigations have shown that different QPX isolates display varying levels of pathogenicity toward clams. Similarly, fi...
متن کاملModulatory effects of hard clam (Mercenaria mercenaria) tissue extracts on the in vitro growth of its pathogen QPX.
Quahog parasite unknown (QPX) is a fatal protistan parasite affecting cultured and wild hard clams Mercenaria mercenaria along the northeastern coasts of the USA and maritime Canada. Field investigations and laboratory transmission studies revealed some variations in the susceptibility of different hard clam stocks to QPX infection. In this study, we used in vitro QPX cultures to investigate th...
متن کاملAlterations of the immune transcriptome in resistant and susceptible hard clams (Mercenaria mercenaria) in response to Quahog Parasite Unknown (QPX) and temperature.
Quahog Parasite Unknown (QPX) is a fatal protistan parasite that causes severe losses in the hard clam (Mercenaria mercenaria) fisheries along the northeastern coast of the US. Field and laboratory studies of QPX disease have demonstrated a major role for water temperature and M. mercenaria genetic origin in disease development. Infections are more likely to occur at cold temperatures, with cla...
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 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...
