A Disease of Freshwater Fishes Caused by Tetrahymena corlissi Thompson, 1955, and a Key for Identification of Holotrich Ciliates of Freshwater Fishes

A disease of freshwater fishes caused by Tetrahymena corlissi Thompson, 1955, and a key for identification of holotrich ciliates of freshwater fishes.

Tetrahymena corlissi, a free-living protozoan, apparently caused the death of large number of guppies (Poecilia reticulatus) and occasionally other fishes, in aquaria and hatcheries at several locations. Apparently the disease occurs when the fish and protozoan populations are both at a high level of density. The signs include white spots and epidermal damage. Histologically, T. corlissi could ...
