Abstract

Irvin A.D., Boarer C.D.H., Kurtti T.J. and Ocama J.G.R. 1981. The incorporation of radio-labelled nucleic acid precursors by Theileria parva in bovine blood and salivary glands of Rhipicephalus appendiculatus ticks. International Journal for Parasitology 11:451-456. The uptake of radio-labelled nucleic acid precursors by blood and tick salivary gland forms of Theileria pana was studied. Piroplasms took up tritiated purines, particularly hypoxanthine, but not pyrimidines. Similar uptake was recorded by T. parva, both in tick saliva and in salivary glands maintained in vitro. Intermediate parasite stages were those most readily labelled in glands; this reflected active nucleic acid synthesis associated with rapid parasite division. Radio-labelling of T. parva in tick salivary glands could be of value in procedures used for concentrating and purifying theilerial sporozoites.
