| Abstract: | SUMMARY Imidocarb diproprionate (IMDP) was used therapeutically at a dose of 1.2 mg IMDP/kg of body weight against Theileria sergenti infections in Hereford heifers on the island of Jeju-Do, Republic of Korea. In the first experiment IMDP was seen to be at least as effective in reducing T. sergenti parasitaemias as primaquine phosphate (primaquine), the drug normally used on the island. In the second and third experiments IMDP was shown to reduce T. sergenti parasitaemias by about 80%. No drug is known to be completely effective against T. sergenti infections but the suggestion is made that IMDP may be used in preference to primaquine for treatment of acutely ill animals since it also has the advantage of eliminating Babesia ovata, another element of the piroplasmosis syndrome on the island. |
