Chemotherapy of Theileria parva lawrencei infections in cattle with halofuginone.
Halofuginone lactate, given once orally at a dosage rate of 1,2 mg/kg body mass on the 1st, 3rd or 5th days of fever, resulted in the recovery of only 1 out of 5 splenectomized cattle. Three splenectomized animals, treated on the 1st as well as the 4th day of fever, recovered and were then carriers. Six untreated controls all died. The potential value of a chemotherapeutic agent for Theileria p...
متن کاملComparative infection rates of Theileria parva lawrencei in salivary glands of Rhipicephalus appendiculatus and Rhipicephalus zambeziensis.
Three cattle, which had been experimentally infected with Theileria parva lawrencei and maintained as carriers of the infection, were each infested simultaneously with clean nymphal Rhipicephalus appendiculatus and Rhipicephalus zambeziensis in ear bags on separate ears. After moulting, the ensuing adult ticks were fed on rabbits for 4 days and their salivary glands were examined for infective ...
متن کاملTheileria parva infection induces autocrine growth of bovine lymphocytes.
Bovine lymphocytes infected with the parasite Theileria parva continuously secrete a growth factor that is essential for their proliferation in vitro and also constitutively express interleukin 2 receptors on their surface. Dilution of the secreted growth factor, caused by culturing cells at low density, results in retardation of culture growth. Human recombinant interleukin 2, however, effecti...
متن کاملExposure of vaccinated and naive cattle to natural challenge from buffalo-derived Theileria parva
Integrative management of wildlife and livestock requires a clear understanding of the diseases transmitted between the two populations. The tick-borne protozoan parasite Theileria parva causes two distinct diseases in cattle, East Coast fever and Corridor disease, following infection with parasites derived from cattle or buffalo, respectively. In this study, cattle were immunized with a live s...
متن کاملTheileriosis in South Africa: a brief review
East Coast fever caused by Theileria parva parva has been eradicated from South Africa, but tick-borne infections with other species of Theileria still occur, particularly in cattle and African buffalo (Syncerus caffer). One such infection is Corridor disease caused by T. parva lawrencei, which is controlled by restricting the movement of African buffalo. Other species reviewed are T. parva bov...
