Extract Coccidiosis has long been recognized as a disease entity in sheep and cattle in many countries, particularly in Europe and the United States. In New Zealand there is some doubt as to the significance of ruminant coccidiosis. Osborne and Ensor (1954) Cooper, H. and Gulati, A. N. 1926. On the occurrence of Isospora and Balantidium in cattle. Mem. Dept. Agric. India, vet. Ser., 3, : 191–193. [Google Scholar] have implicated coecidial infections in scouring calves while Salisbury et al. (1953) Ernst, J. V. , Stevens, R. O. and Cooper, C.
