Molecular characterisation of a cognate 70 kDa heat shock protein of the protozoan parasite Theileria parva por Daubenberger, C.A., Heussler, V., Gobright, E.I., Wijngaard, P.L.J., Clevers, H.C., Wells, C., Tsuji, N., Musoke, A.J., McKeever, Declan J.

“…From this library, several colonies carrying parasite encoded genes were identified and are currently being characterised. Since heat shock proteins (hsp) of many infectious agents are known to constiute dominant antigens that may play an important role in the host-parasite relationship (4), we focused our attention on a newly cloned hsp gene, with the aim of elucidating its relevance to T. parva immunity.…”
