THE SPORULATED OOCYSTS OF EIMERIA ANKARENSIS N. SP. AND OF OTHER SPECIES OF EIMERIA OF BUFFALO IN TURKEY AND TRANSMISSION OF FOUR SPECIES OF EIMERIA FROM BUFFALO TO COW CAL VE S

Climatic conditions in many parts of Turkeyare suitable for sporulation and survival of coccidia oocysts. Our investigation shows that cattle pass a wide variety of oocysts in their feces during all seasons of the year and nearly hundred percent incidence of infection is encountered in some healthy heards. Clinical coccidiosis is also known to be common in this animal and it is of considerable economic importance. But the problem in buffalo (Bubalus bubalis) has not received much attention and no work on its coccidia was undertaken (36). The studies in various countries showed that the most of Ei. meria species which were recorded from cattle also occured in buf. falo and became the causative agents of clinical coccidiosis in thcil' calves (24, 25, ıo, 39, 35). Up to date at least 2 i species of Eimeria have been reported from cattle and 16 species from buffalo. But some of these are presently considered valid and the others are not (18, 19, 26, 27, 2, 8, 24). This report providesan information on incidence and number of Eimeria spccies occurring in buffah? from Turkey. It describes a
