Oxidative burst in hard clam (Mercenaria mercenaria) haemocytes.
Haemocytes of bivalve molluscs are known to be responsible for many immunological functions, including recognition, phagocytosis, and killing or elimination of invading microorganisms, such as potentially infective bacteria and parasites. In many bivalves, killing of microorganisms engulfed by haemocytes is accomplished by a sudden release of reactive oxygen species (ROS) within the haemocytes;...
متن کاملSpermatogenesis in the Hard-Shell Clam (Venus Mercenaria Linnaeus) *
Neither Kellogg7 nor Belding' in their papers on the biology of V. mercenaria give a description of spermatogenesis occurring in this animal, and until the present time the general features of this process in dams have not been described. In the case of some other lamellibranchiate mollusks, more information on the development of the gonad and gamete formation is available. Hoek' described the ...
متن کاملEffects of salinity on hard clam (Mercenaria mercenaria) defense parameters and QPX disease dynamics.
QPX (Quahog Parasite Unknown) is a protistan parasite affecting hard clams (Mercenaria mercenaria) along the Northeast coast of the United States. The fact that QPX disease epizootics are usually observed in field sites with high salinities led to the general assumption that salinity represents an important factor for disease distribution. This study was designed to investigate the effect of sa...
متن کاملEnvironmental salinity modulates the effects of elevated CO2 levels on juvenile hard-shell clams, Mercenaria mercenaria.
Ocean acidification due to increasing atmospheric CO2 concentrations results in a decrease in seawater pH and shifts in the carbonate chemistry that can negatively affect marine organisms. Marine bivalves such as the hard-shell clam, Mercenaria mercenaria, serve as ecosystem engineers in estuaries and coastal zones of the western Atlantic and, as for many marine calcifiers, are sensitive to the...
متن کاملQuantitative real-time PCR assay for QPX (Thraustochytriidae), a parasite of the hard clam (Mercenaria mercenaria).
We developed a real-time quantitative PCR (qPCR) assay targeting the rRNA internal transcribed spacer region of the hard clam pathogen QPX. The qPCR assay was more sensitive than was histology in detecting clams with light QPX infections. QPX was detected in 4 of 43 sediment samples but in none of 40 seawater samples.
