Artificial infection of the tick Rhipicephalus appendiculatus with Theileria parva
Research in Veterinary Science, 1979Methods for infecting Rhipicephalus appendiculatus ticks with Theileria parva by injection and by artificial feeding were confirmed and compared. The injection method proved simpler and at best as effective and suggested improvements are described.

Dose dependent responses of cattle to Theileria parva stabilate
International Journal for Parasitology, 1984Abstract Dolan T. T. , Young A.S. , Losos G.J. , McMillan I. , Minder Ch.E. and Soulsby K. 1984. Dose dependent responses of Theileria parva stabilate. International Journal for Parasitology14: 89–95. A tick derived stabilate of Theileria parva (Maguga) was titrated in a large group of Boran (Bos indicus) cattle of the same age, sex and ...

Aureomycin in Thieileria parva Infection
Nature, 1953RECOGNITION of the selective action of quinine, atebrin and chloroquine on the haemotropic trophozoites of certain Plasmodium species, and that of plasmoquine on the exoerythrocytic trophozoites as well as on the gametocytes, forms the bases of modern chemotherapy of malaria in laboratory animals and in man.

Simulation in vitro of bovine host cycle of Theileria parva
Nature, 1976Theileria parva is a tick-transmitted parasite causing East Coast fever in cattle. Research on T. parva has been impeded because of difficulties in completing the mammalian part of its life cycle in any non-bovine host. Several attempts to adapt the organism to small laboratory animals have failed1–5.

The molecular basis of transformation of lymphocytes by Theileria parva infection
Seminars in Cell Biology, 1993The protozoan intracellular parasites, Theileria parva and Theileria annulata, infect cattle and cause severe and fatal leukocytic proliferative diseases. The proliferation is dependent on the presence of the parasites in the host cell cytoplasm. T. parva-infected cells proliferate permanently in cell culture and exhibit many features characteristic of

The effect of immunisation with BCG on Theileria parva infection in cattle
Research in Veterinary Science, 1980Cattle were immunised with 10(8) bacillus Calmette-Guerin (BCG) organisms 32 days before challenge with a lethal dose of Theileria parva stabilate. The disease reactions of immunised and control cattle were similar and all infected cattle died. It is suggested that the failure of BCG to protect cattle against T parva infection is because the cattle ...

A Theileria parva type 1 protein phosphatase activity
Molecular and Biochemical Parasitology, 2000The protozoan parasite Theileria (spp. parva and annulata) infects bovine leukocytes and provokes a leukaemia-like disease in vivo. In this study, we have detected a type 1 serine/threonine phosphatase activity with phosphorylase a as a substrate, in protein extracts of parasites purified from infected B lymphocytes. In contrast to this type 1 activity,

Bulk-freezing of Theileria parva stabilates for vaccine production
International Journal for Parasitology, 1996The freezing and thawing characteristics of different volume samples of freezing medium and Theileria parva stabilates were studied in order to identify suitable conditions for freezing large volumes of stabilates for use in the preparation of vaccines.

The serological relationship between Theileria parva (Muguga) and Theileria lawrence from Rhodesia
Veterinary Record, 1977Thirty-eight sera from cattle from a herd in Rhodesia naturally infected with Theileria lawrencei were titrated with the indirect immunofluorescent test against schizont antigens of T parva (Muguga) and T lawrencei from Rhodesia. T lawrencei was found to be indistinguishable from T parva with the test.

The kinetics of Theileria parva infection and lymphocyte transformation in vitro
International Journal for Parasitology, 2006Theileriaparva is an intracellular protozoan parasite that causes a fatal lymphoproliferative disease of cattle known as East Coast Fever. The parasite infects host lymphocytes causing their transformation and uncontrolled proliferation. Infiltration of major organs with parasitized lymphoblasts results in most cases in death within 3 weeks.
