Abstract
Lambs infected with the coccidia E. ninae-kohl-yakimovi and E. faurei exhibited clinical symptoms of lowered feed consumption, lassitude, generalized incoordination and slight scouring with some bleeding. No significant decrease in water consumption per pound of lamb took place. A decrease in the percentage of feed protein digested occurred. Changes in albumin globulin ratio indicated an increase in globulins. Blood hemoglobin and hematocrit values indicated a lack of even moderate hemorrhage. Inorganic phosphorus levels of the blood serum dropped and blood glucose levels rose. All of the physiological changes that took place in the host could be correlated with the growth and development of the endogenous phases in the life cycle of the coccidia.
