Tissue Distribution and Abundance of the Parasitic Dinoflagellate <i>Hematodinium perezi</i> in Naturally Infected <i>Portunus trituberculatus</i>.

ABSTRACT: The parasitic dinoflagellate Hematodinium is an infectious pathogen that causes severe enzootic in numerous economically important marine crustaceans worldwide. Previous research has focused on investigating the identification and life stages of Hematodinium parasites, while the parasite abundance and tissue proliferation process of Hematodinium in naturally infected crustacean hosts need to be further studied. In the present study, the tissue tropisms and intensity of H. perezi were investigated in the naturally infected Chinese swimming crabs Portunus trituberculatus by both the qualitative (hemolymph assay, histology) and quantitative analysis (cell count, quantitative PCR). The results showed that in P. trituberculatus with infection level I (4
