Therapeutic efficacy of Butakur against bovine theileriosis in the Caspian Sea Region of Russia

The purpose of the research is studying therapeutic properties of Butakur against spontaneous bovine theileriosis.

Materials and methods. Butakur was used on the Yalgin Farm and at the Umarov Agricultural Enterprise in the Karabudakhkentskiy District to treat 30 animals in the early stage of the disease at a body temperature of 40.4–41.7 0C and a parasitic reaction of 30.2%. Piroplasmids were differentiated by microscopy of smears, imprints of lymph nodes and peripheral blood, and by detected purple bodies and parasites in them, excluding mixed infection. Two groups of animals were formed on the principle of analogs. In the test group (n = 15), Butakur was used as a specific therapy at a dose of 2.5 mg/kg for the active substance at a rate of 1 ml/20 kg of body weight, and the antimalarial drug Delagil (chloroquine) was used in the control group at a dose of 15 mg/kg within 4–5 days. A different combination of chemotherapy drugs with symptom-directed and pathogenetic drugs was used simultaneously.

Results and discussion. Butakur was the most effective when used in the early period of the disease development from the moment the body temperature rose and until a slight parasitemia in erythrocytes was observed with the simultaneous use of symptom-directed and pathogenetic drugs. Out of 15 animals that received Butakur at a dose of 1 ml/20 kg (2.5 mg/kg for the active substance), 13 animals recovered, and the efficacy was 86.6%.
