Seasonal infection intensity cycle of the parasite Perkinsus marinus (and an absence of Haplosporidium spp.) in oysters from a South Carolina salt marsh

Abstract

Investigation of the prevalence of the protozoan parasite Perkinsus marinus in populations of intertidal oysters Crassostrea virginica led to the finding of a distinct, 4 phase cycle of infection intensity. Infection intensity had a significant positive correlation with temperature and salinity, and a negative correlation with oyster condition index. -from Authors
