Sitta, TatjanaHenson, Sonal P.Morrison, W. IvanToye, Philip G.[Similar levels of diversity in the gene encoding the p67 sporozoite surface protein of Theileria parva are observed in blood samples from buffalo and cattle naturally infected from buffalo]Similar levels of diversity in the gene encoding the p67 sporozoite surface protein of Theileria parva are observed in blood samples from buffalo and cattle naturally infected from buffalo

An infection and treatment protocol is used to vaccinate cattle against Theileria parva infection. Due to incomplete cross-protection between different parasite isolates, a mixture of three isolates, termed the Muguga cocktail, is used for vaccination. While vaccination of cattle in some regions ...


Hemmink, J.D.Weir, W.MacHugh, Niall D.Graham, S.P.Patel, EktaPaxton, E.Shiels, B.Toye, Philip G.Morrison, W. IvanPelle, Roger[Limited genetic and antigenic diversity within parasite isolates used in a live vaccine against Theileria parva]Limited genetic and antigenic diversity within parasite isolates used in a live vaccine against Theileria parva

This review of the prospects for developing an immunization procedure against trypanosomiasis explores a number of promising avenues of research. Part I covers variable antigen types (VATs); metacyclic antigens; in vivo and in vitro attenuation; and molecular and genetic engineering. Part II, to ...


Murray, M.Barry, J.D.Morrison, W. IvanWilliams, R.O.Hirumi, H.Rovis, L.A.[A review of the prospects for vaccination in African trypanosomiasis. Part I]A review of the prospects for vaccination in African trypanosomiasis. Part I

Theileria parva is an intracellular sporozoan parasite that infects and transforms bovine lymphocytes, causing a severe lymphoproliferative disease known as East Coast fever in eastern, central and southern Africa. In this article, Declan McKeever and colleagues summarize the current understandin...

A first-gneration subunit vaccine for East Coast fever based on the Theileria parva p67 sporozoite surface antigen is entering preliminary field trials. Intensive efforts are also focused on the identification of a schizont-specific omponen for incorporation in a second-generation multi-component...


McKeever, Declan J.Morrison, W. Ivan[Invited review Novel vaccines against Theileria parva: prospects for sustainability]Invited review Novel vaccines against Theileria parva: prospects for sustainability

In part I of this review of the prospects of vaccination against African trypanosomiasis, contained in the previous issue of World Animal Review, the constraints in developing a vaccine were discussed and current knowledge on the molecular biology of the trypanosome and on antigenic variation wit...

Studies of the immune responses of cattle to Theileria parva have provided evidence that immunity to the parasite can operate at two levels, namely the sporozoite and the schizont-infected lymphoblast. Antibodies that neutralize the infectivity of sporozoites have been detected in the serum of hy...

Respiratory failure and death in East Coast Fever (ECF), a clinical syndrome of African cattle caused by the apicomplexan parasite Theileria parva, has historically been attributed to pulmonary infiltration by infected lymphocytes. However, immunohistochemical staining of tissue from T. parva inf...
