摘要	The parasitic dinoflagellates of the Hematodinium genus have impacted wild and cultured stocks of commercial crustaceans worldwide. In the past decade, outbreaks of Hematodinium epizootics resulted in substantial mortalities in cultured Chinese swimming crabs Portunus trituberculatus in the polyculture ponds located in Shandong Peninsula, whereas the source and transmission of the parasite in the polyculture pond system remains to be determined. During April to December of 2018, 2034 crabs and 108 shrimps were collected from the polyculture pond systems in the highly endemic area of Hematodinium diseases in Qingdao, Shandong Province. Among those, 188 individuals of the 6 crab species were infected by the parasite, including 4 novel host species (Uca arcuate, Hemigrapsus penicillatus, Helice wuana and Macrophthalmus japonicas). No infection was identified in Penaeus monodon. Further phylogenetic analyses indicated that the Hematodinium isolate infecting the six crab hosts, together with other isolates reported from China, composed the genotype II of Hematodinium perezi. The parasite was more infectious to cultured Portunus trituberculatus and the dominant wild crab Helice tientsinensis dwelling in the waterways connecting to the polyculture ponds, even though it was found to be a host generalist pathogen. The prevalence of Hematodinium perezi infection in Helice tientsinensis was higher than that of other wild crabs and showed significant positive correlation with that of the cultured Portunus trituberculatus. The results indicated that the wild crabs, particularly Helice tientsinensis, were the important alternate hosts closely involved in transmission and spreading of the Hematodinium disease in the polyculture pond systems.
