Abstract

Kessler's goby, a recently introduced fish species in the Budapest region of the river Danube, proved to be infected with two previously undescribed coccidian species. The species having a smaller oocyst (7-8.5 μm) proved to be a Goussia and was named G. kessleri sp. n. The species having larger oocysts measuring 13-14 μm showed characteristics typical of an Eimeria and was designated as E. daviesae sp. n. Oocyst of G. kessleri were spherical, contained four ellipsoidal sporocysts lacking Stieda body. Sporocysts measured 5.8 (5-6) x 3.9 (3.8-4) μm. Oocysts of E. kessleri were spherical, contained four short ellipsoidal sporocysts which tapered at one end and formed at that end a cap-like Stieda body. Sporocysts measured 8 (7.5-8.2) x 4.9 (4.8-5.2) μm. Both species formed oocysts in the intestinal epithelium. The oocysts of the Goussia were released sporulated, while those of the Eimeria passed in unsporulated or semisporulated condition.
