Abstract
During field studies in Kenya it was found that a high proportion (approaching 100%) of cattle in East Coast fever (E.C.F.) endemic areas harboured Theileria piroplasms and the majority had significant antibody titres to both T. parva and T. mutans. For years controversy has arisen over whether or not T. parva infection has a prolonged carrier state in cattle. The general view has been that the carrier state of T. parva is rare and immunity is normally sterile (Neitz, 1957; Wilde, 1967; Barnett, 1968; Barnett, 1977). However, there have been several reports of the carrier state in T. parva infection (Barnett & Brocklesby, 1966a). T. lawrencei and T. bovis, now believed to be the same species as T. parva (Uilenberg, 1981), frequently have a carrier state in both cattle and African buffalo (Barnett & Brocklesby, 1966b; Neitz, 1957; Young et al, 1978).
