Goussia is a genus of parasitic alveolates belonging to the phylum Apicomplexia. Although most species in this genus infect fish but a small number infect frogs.
Species in this genus are tetrasporocystic, dizoic, lack Stieda bodies and have sporocyst walls consisting of two valves joined by a longitudinal suture.
These species usually infect the gut of the host but some may also infect the gall bladder, kidney, liver, spleen and swim bladder.
The genus was first described by Labbe in 1896.
The relationship of this genus to the others in this order is not well understood. It may be an early branching clade.
