THE SPECİES OF EİMERİA OCCURRİNG İN CATTLE İN TURKEY

Abstract

ClimaLİc conditions in many parts of Turkeyare suitable for . sporulation and survival of coccidia oocysts. Routine faecal examinations in our laboratory show that cattle discharge a wide variety. of oocysts during all seasons of the year and a hundered percent incidence of infeetiem is frequently encountered in healthy herds. Clinical eoecidiosis is also known to be present in ealves and has been eonsidered important for economie losses. In recent years a survey of oocysts occurring in the faeces of eattle in neighbourhood of Ankara was carried out and eight species of Eimeria were identified (22). The identification was based on the morphological criteria of their unsporulated oocysts alone, but ıecent works (17, 18, ıg, 23, 31) have shown that sporulated oocysts are neeassary for valid differentiations. Indced there is praeticaIIy not enough information on the oceurrenee of the various speeies of Eimeria present in eattIe in this country (35). The purpose of this paper is to set out the results obtained from a survey of faeeal specimens whieh were examined in order to determine the speeie~of Eimeria present in eattle in Turkeyand to provide a brief note on the diagnostic features of ooeysts of these .speeies for the guidanee. of workers interested in. the disease in this country.
