1990, Poncelet et al. 1990, Uggla et al. 1989, Wolf et al. 1991) support the diagnosis of N. caninum infection. This report further extends the geographic range of canine neosporosis. The source of infection, life cycle of the parasite and treatment of neosporosis in dogs are unknown (Dubey 1990). But veterinarians should be alert to the fact that TV. caninum can be highly pathogenic and distinct from T. gondii. ACKNOWLEDGEMENT The authors thank Prof. T. Kassai for his helpful comments. Sréter, T., Sebestyén, P. és Dubey, J. P.: A kutyák neosporosisának első hazai megállapítása Egy kéthónapos Basset hound kölykön a hátsó végtagok paresise, majd paralysise jelentkezett. A kutya egy évi betegség után a rendszeres kezelések ellenére részlegesen megbénult, majd elhullott. A szövettani vizsgálat súlyos, nem-gennyes, elhalásos meningoencephalitist állapított meg. Az agyvelőben N. caninumra jellemző tachyzoiták és cysták voltak. REFERENCES Anderson, M. L., Blanchard, P.C., Barr, B.C., Dubey, J.P., Hoffman, R. L. and Conrad,P. A.
