Research in Veterinary Science. 1-20.https://kalroerepository.kalro.org/handle/0/11202T a number of tick-borne diseases of cattle, young animals show a significant resistance to infection which is independent of maternally transferred or acquired immunity. Such resistance has been detected in babesiosis (Riek 1968, Zwart and Brocklesby, 1979) an: lasmosis (Ristic, 1968; 1981) and heartwater (Uilenberg, 1983), but,10 evidence for an age-related innate resistance has been described in theileriosis apart from the rather equivocal data reported by Adler and Ellenbogen (1935) for calves infected with Theileria annulata.enhttp://creativecommons.org/licenses/by/3.0/Journal Contribution21Tickborne diseasesCattleAnimalsCalves
