(Protozoa: Coccidia) from European Hare (Lepus europaeus Pallas) in Hungary" - Sugár, L. - Parasit. Hung. 11. 13-15. 1978. ABSTRACT. A new intestinal coccidium is described under the name Eimeria babatica sp. n. from a hare in Hungary. Among the intestinal coccidia of the hare Eimeria (E. ) leporis had been described first, by NIESCHULZ in 1923. Later the species E. magna var, robertsoni and E. magna var, robertsoni forma semisculpta were described by MADSEN (1938). In 1943 CARVALHO characterized E. robertsoni as an independent species and described E. magna forma townsendi. In 1956, PELLÉRDY described E.europaea and E.hungarica , and declared E. semisculpta and E. townsendi to be independent. As far as we are informed, in the meantime two additional hare coccidia were described, i.e. E. stefanskii Pastuszko, 1961, and E. belorussica Litvenkova, 1969. In our own parasitological studies conducted during the period 1972-1978, all known intestinal hare coccidia except E. stefanskii and E. belorussica were encountered in hosts indigenous in Hungary. Detailed analysis of the intestinal contents of some massively infected hosts revealed the presence of E.sculpta oocysts and of previously unknown oocysts with well defineable differentiating features from the known intestinal coccidia of the hare. The new species has been named Eimeria babatica after the host's habitat (Gödöllő - Babat Pussta), and its description is presented in this paper. Eimeria babatica sp.n. (Figs. 1, 2A, 3A). Host: European hare (Lepus europaeus Pallas). Origin and habitat: Hungary, Gödöllő - Babat Pussta. Localization: large intestine. Oocyst shape: broad ovoid, less often regular or elongated ovoid, rarely asymmetrical. The inside of the oocyst exhibits a bluish shade. Oocyst dimensions: 20-30x16-21 }i (average: 25x19 u). Oocyst wall: 0.8-O. 9 JJ thick, colourless, smooth, bilayered, with a micropyle 6-8 ja in diameter and surrounded by a conspicuous collar-like projection at the more tapering pole. Sporont: globular or almost globular in shape, 15-17.5 _u in diameter, finely granular. Sporulation takes 60-70 hours at room temperature, in 1% potassium bichromate solution. No oocyst residuum is formed. Sporocysts: 13-15 x 6-7.5 yi (on average 14 x 7 u) in size, elongated ovoid in shape, with a knob-like Stieda body at the bluntly tapering pole. The sporocyst residuum usually consists of a few scattered refractile granules, less often it forms a coherent, elongated mass, up to 6x3 u in size. The brush stroke like sporozoites measure 11-11.5 x 4.2-4. 6ju, and enclose one large and one smaller refractile globule. The endogenous development of the species and the pathological role thereof are unknown.
