 Some of the economically-important infected hosts include tanner and snow crabs from the Northeast Pacific and Atlantic Oceans, blue crabs in the Atlantic and Gulf coasts of the United States, Norwegian lobsters, and Edible crabs from Europe.It is anticipated that the geographical spread of "Hematodinium" will grow and reach various other aquatic regions globally due to oceanic currents, host movements and habitat expansions, as well as transportation vessels.Furthermore, as new crustacean species are targeted and fished as commercial seafood, new species of pathogens may be discovered.
