Abstract
Goussia cichlidarum n. sp. (Barrouxiidae, Apicomplexa) is a coccidian parasite found in the epithelial lining of the swimbladder in a variety of cichlid fish, most commonly inSarotherodon galilaeus. Infected fish were found in Lake Kinneret and in fish ponds in Israel and in Uganda. Natural infections were investigated as well as experimental infections obtained in the laboratory. Merogony and gamogony is completed within a hypertrophic host cell. The latter is displaced to the surface of the epithelial layer and during the parasitization process is reduced to a membranous envelope. This cell remains attached to the epithelial layer up until the stage of oogony. Oocysts complete their differentiation free in the swimbladder lumen.
