STUDIES ON MORPHOLOGICAL CHARACTERRISTICS OF EIMERIA SPECIES OOCYSTS

Abstract   

    Morphologically nine different species of bovine Eimeria were recognized from the faeces of naturally infected calves in North Wales, UK. Various species encountered were E. subspherica, E. zuernil, E. ellipsoidalis/alabamensis (grouped together as a species complex) E. bovis, E. cylindrical, E. Canadensis, E. auburnensis, E. brasiliensis, E. brasilliensis, E. wyomingensis and E. pellira. The largest oocyst measured was of E. brasiliensis and the smallest E. subspherica.    

Key words: Eimeria spp., oocytys, morphological characteristics
