For this purpose, 100 positive samples were collected and examined. The species of Eimeria found were Eimeria ovina, Eimeria intricata, Elmeria parva, Eimeria faurei and Eimeria ninakohlyakimovae. ll samples showed mixed infection with 2 to 3 species of Eimeria. The oocyst count per gram of faeces in positive cases ranged from 6,000 to 50,000. The disease incidence was higher in young animals and it decreased with age. It was observed that Eimeria ninakohlyakimovae was the most prevalent (307.) amongst the faecal samples examined. For haematological purposes, 60 blood samples of lambs 4-6 months of age were used. The lambs were divided into three groups A, B and C having 20 animals each respectively. The result indicated that total erythrocyte count for group A, B and C was 6.4 ± 0.3, 10.7 ± 0.2 and 11.8 ± 0.2 millions per micro litre of blood respectively. A significant decrease in total erythrocyte count was observed. A negative correlation existed between the average oocyst count and number of erythrocytes per micro litre of blood. The average leukocyte count of group A was found to be 7.00 ± 0.1 x 103 thousand per micro litre of blood while in group B and C, the average leukocyte count was 7.8 ± 0.2 and 8.4 ± 0.2x103 respectively. The result indicated that a 13.25%. decrease in animal showing clinical sign of coccidiosis and 7.237. decrease in the animal showing sub-clinical (group B) form of disease. The neutrophil count was observed 40.05 ± 0.25, 36.65 ± 0.25 and 32.6 ± 0.28 for group A, B and C respectively. The average lymphocyte count of group A, B and C was 56.15 ± 0.23, 55.85 ±0.28 and 62.0 ± 0.29 respectively. It is clear that the coccidiosis caused 7.62% decrease in lymphocytes in infected lambs. The result indicated a significant decrease in lymphocyte count due to coccidiosis. The result also showed that in clinical cases of coccidiosis the monocyte count increased by 10% but non-significant in blood of infected lambs was observed. It was evident from the result that a decrease of 64.29% in the eosinophil count was seen in group A and 7.14% in group C because the coccidiosis caused significant change in the eosinophil count. The average basophil count for group A, and C was 0.5 ± 0.17, 0.4 ± 0.17% and 0.15 ± 0.137. respectively was observed in infected lambs ER -
