Blood cellular responses in Sarcosystis tenella infected lambs treated with Toltrazuril

Sheep husbandry contributes immensely to Indian agricultural economy in the form of wool, mutton, leather, milk and casing production. Sarcosystis has recently been recognized as most prevalent and highly pathogenic protozoan infection in sheep in India with a high prevalence rate of up to 80%. Out of four species of sarcosystis, Sarcosystis tenella is found to be the most pathogenic species which may cause major health problem. There is no other information on sarcocystosis of lambs from India. Thus, in the present investigation an attempt has been made to study the clinico- pathological and haematological alterations in sarcosystis infected lambs. The present study also showed partial efficacy of anti-coccidial drug Toltazuril in sarcosytosis.
