Hematodinium infections in cultured Chinese swimming crab, Portunus trituberculatus, in northern China
Since 2004, the parasitic dinoflagellates Hematodinium emerged as causative agent of the "milky blood disease" in cultured Portunus trituberculatus, Scylla serrata and Exopalaemon carinicauda along the coastal areas of southern China; while, no Hematodinium infections had been reported in...
