Minami, J.Spooner, P.R.Irvin, A.D.Ocama, J.G.R.Dobbelaere, D.A.E.[An in vitro test for the possible differentiation of theilerial strains based on the use of monoclonal antibodies]An in vitro test for the possible differentiation of theilerial strains based on the use of monoclonal antibodies

Theileria are tick-transmitted, haemoprotozoan parasites infecting wild and domestic ungulates throughout many areas of the world. The most economically important species are T. parva and T. annulata which are pathogenic to cattle, and T. lestoquardi (syn hirci) which is pathogenic to sheep and g...


Skilton, Robert A.Musoke, A.J.Nene, VishvanathWasawo, D.P.S.Wells, C.W.Spooner, P.R.Bishop, Richard P.Osaso, J.Nkonge, C.Latif, A.Morzaria, S.P.[Molecular characterisation of a Theileria lestoquardi gene encoding a candidate sporozoite vaccine antigen]Molecular characterisation of a Theileria lestoquardi gene encoding a candidate sporozoite vaccine antigen

Field and experimental bovine infection sera were used in immunoblots of sporozoite and schizont lysates of Theileria parva to identify candidate diagnostic antigens. Four parasite antigens of Mr 67,000 (p67), 85,000 (the polymorphic immunodominant molecule, PIM), 104,000 (p104), and 150,000 (p15...


Katende, J.Morzaria, S.P.Toye, Philip G.Skilton, Robert A.Nene, VishvanathNkonge, C.Musoke, A.J.[An enzyme-linked immunosorbent assay for detection of Theileria parva antibodies in cattle using a recombinant polymorphic immunodominant molecule]An enzyme-linked immunosorbent assay for detection of Theileria parva antibodies in cattle using a recombinant polymorphic immunodominant molecule

In order to define whether the variable antigenic type RoTat 1.2 is restricted to Trypansoma evansi and could be used as antigen in serological tests to differentiate T. evansi from Trypansoma equiperdum, the appearance of RoTat 1.2-specific antibodies in rabbits, experimentally infected with T...


Claes, F.Verloo, D.Waal, D.T. deMajiwa, P.A.O.Baltz, T.Goddeeris, B.M.Buscher, P.[The expression of RoTat 1.2 variable surface glycoprotein (VSG) in Trypanosoma evansi and T. equiperdum]The expression of RoTat 1.2 variable surface glycoprotein (VSG) in Trypanosoma evansi and T. equiperdum

Serum Ig from Trypanosoma congolense-infected cattle were affinity-purified using immobilised trypanosome or non-trypanosome antigens (beta-galactosidase, cytochrome C and ferritin). The bound and unbound IgG and IgM fractions were collected and tested in ELISA for reactivity to each antigen. The...


Buza, J.Naessens, Jan[Trypanosome non-specific IgM antibodies detected in serum of Trypanosoma congolense-infected cattle are polyreactive]Trypanosome non-specific IgM antibodies detected in serum of Trypanosoma congolense-infected cattle are polyreactive

Understanding the basis of protective immunity to Cowdria ruminantium will facilitate the development of an effective subunit vaccine against heartwater in ruminants and contribute to a better definition of protective immune mechanisms to obligate intracellular pathogens in general. Until recentl...


Totte, P.Bensaid, A.Mahan, S.M.Martínez, D.McKeever, Declan J.[Immune responses to Cowdria ruminantium infections]Immune responses to Cowdria ruminantium infections

We describe a highly sensitive, non-radioactive assay for T cell activation, based on the rapid induction of class II MHC expression by constitutively negative bovine endothelial cells, when cultured in the presence of supernatants derived from activated bovine T cells. We demonstrate the effecti...


Ballingall, K.T.Mwangi, D.M.MacHugh, Niall D.Taracha, E.L.N.Totte, P.McKeever, Declan J.[A highly sensitive, non-radioactive assay for T cell activation in cattle: Applications in screening for antigens recognised by CD4+ and CD8+ T cells]A highly sensitive, non-radioactive assay for T cell activation in cattle: Applications in screening for antigens recognised by CD4+ and CD8+ T cells
Webster, P.Russo, D.C.W.Black, S.J.[The interaction of Trypanosoma brucei with antibodies to variant surface glycoproteins]The interaction of Trypanosoma brucei with antibodies to variant surface glycoproteins

Two novel baculovirus-derived recombinant Theileria parva p67 constructs were tested for their vaccine potential against East Coast fever. Boran calves were immunized with a his-GFP-p67 fusion protein (GFP:p67DeltaSS) or with GP64:p67C, a protein fusion between a C-terminal domain of p67 and th...


Kaba, S.A.Musoke, A.J.Schaap, D.Schetters, T.Rowlands, G.J.Vermeulen, A.N.Nene, VishvanathVlak, J.M.Oers, M.M. van[Novel baculovirus-derived p67 subunit vaccines efficacious against East Coast fever in cattle]Novel baculovirus-derived p67 subunit vaccines efficacious against East Coast fever in cattle

Two recombinant vaccines against Theileria parva, based on a near full-length version of the sporozoite surface antigen p67 (p67635), or an 80 amino acid C-terminal section (p67C), were evaluated by exposure of immunized cattle to natural tick challenge in two sites at the Kenya Coast and one i...
