Goussia janae n. sp. (Apicomplexa, Eimeriorina) in dace Leuciscus leuciscus and chub L. cephalus

Abstract

Goussia janae n. sp. is described from the intestine of dace Leuciscus leuciscus and chub L. cephalus. Merogonic, gamogonic and sporogonic stages are localized intracellularly in the apical part of the epithelial cells just beneath the cell membrane, i.e. in the 'epicellular' position. Ellipsoidal oocysts have a mean size of 18.1 x 12.7 μm and are without oocyst residuum; ellipsoidal sporocysts (13.5 x 5.0 μm) lack Stieda body and sporocyst residuum. © Inter-Research.
