Summary
Parvaquone was used in 13 cattle naturally infected withTheileria annulata. Blood smears and lymph node biopsy smears were taken, stained and examined for the presence of the piroplasm and schizont stages of the parasite respectively. Smears were examined before and on the third, fifth and seventh day after commencement of therapy. Two doses of parvaquone were injected in the neck intramuscularly at 10mg/kg bodyweight at 48 hour intervals. Of the 13 cattle treated 11 were discharged in fairly good condition and two died of tropical theileriosis on the sixth day after commencement of treatment.
