The number of reported paramoebiasis outbreaks has increased in recent years; warming seawater temperature is a likely contributor and future risk. An important challenge is to understand, and ultimately control, the paramoebiases that affect farmed fish. Recent molecular investigations have expanded the known genetic diversity of Paramoeba and Neoparamoeba species, although it is unclear whether these two genera represent monophyletic...
