With a view to increasing milk production in short time, extensive pro grammes of improving indigenous cattle by breeding them with exotic da iry cattle are under way in many a Third world countries including Ind ia. The success of these programmes is threatened by theileriosis (The ileria annulata) as the improved cattle are highly susceptible to the disease after suffering mortality of up to 90%. The infection scenario in nature being subject to several variables need critical evaluation for arriving at correct diagnosis. The author has described here 7 na tural outbreaks of theileriosis, their course, signs and results of la boratory examination and discussed critically the data establishing de finitive diagnosis.
