Differentiation from the genus " Haemogregarina " may be difficult as in both genera gametocytogenesis occurs in the erythrocytes and are have similar morphology.
2.
The �rst suborder, Adeleorina, comprises coccidia of invertebrates and the coccidia that alternate between blood-sucking invertebrates and various vertebrates; this group includes " Haemogregarina " and " Hepatozoon ".
3.
They can be distinguished on the location of schizogony : In " Karyolysus " this occurs in the endothelial cells of the visera while in " Haemogregarina " schizogony occurs in the bone marrow.

Three parasites ( " Ceratomyxa shasta ", " Cryptobia salmositica ", and " Haemogregarina irkalukpiki " ) were identified as posing the greatest threat to the fisheries resources of the immediate area and also to the downstream areas.
5.
Other parasites of this species include a species of myxosporean in the genus " Kudoa ", which infests the skeletal muscles, the hemogregarine protozoan " Haemogregarina hemiscyllii ", which infects the blood, the ostracod " Sheina orri ", which attaches to the gills, and the nematode " Proleptus australis ", which infests the stomach.
