چکیده انگلیسی
Hematodinium sp. is a parasitic dinoflagellate reported to cause disease and death in a variety of crustacean species including the blue crab (Callinectes sapidus). However, because of difficulties in the culture of Hematodinium sp. associated with blue crabs, little is known about its life cycle or mode of transmission. Here, we report the first detection of this organism outside of a metazoan host and provide evidence that this life stage can act as an infective agent. Observations of dinospores in crab hemolymph samples suggest that dinospores may be responsible for waterborne disease transmission. Additionally, we developed and validated a quantitative Real Time PCR assay for the detection of Hematodinium sp. inside and outside of a host organism that will be useful for future investigations of Hematodinium biology and Hematodinium sp.-infection etiology. Based on the observations of a free-living form of Hematodinium sp. and the association of this parasite with a widespread epizootic in blue crab populations, we propose that Hematodinium sp. be considered a Harmful Algal Bloom species.
