Item East Coast Fever the Significance of Host Ace in Infection or Immunization of Cattle with Theileria Parva(1979) Irvin, A.D.; Dobbelaere, D.A.E.; Morzaria, S.P.; Spooner, P.R.; Dolan, T.T.; Young, A.S.; Gettinby, G.; International Laboratory for Research on Animal Diseases, Nairobi, Kenya; Kenya Agricultural Research Institute, Muguga, Kenya; University of Strathclyde, Glasgow, UKT 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.Item Susceptibility to trypanosomosis of three Bos indicus cattle breeds in areas of differing tsetse fly challenge(1998) Mwangi, E. K.; Stevenson, P.; Gettinby, G.; Reid, S. W. J.; Murray, M.; Kenya Trypanosomiasis Research Institute; Kenya Trypanosomiasis Research Institute, P.O. Box 362KikuyuKenya, Department of Statistics and Modelling Science, University of Strathclyde, Livingstone TowerG1 1XH Glasgow, Scotland UK Department of Veterinary Clinical Studies, University of Glasgow Veterinary School, Bearsden Road, BearsdenGlasgow G61 1QH, ScotlandUKStudies to assess the differences in susceptibility to trypanosomosis among Bos indicus cattle breeds (Maasai Zebu, Orma Boran and Galana Boran) were conducted under conditions of varying tsetse fly challenge at the Nguruman escarpment in south-western Kenya, for a period of 1 year. It was found that under tsetse challenge quantified as high, Maasai Zebu and Orma Boran were less susceptible than Galana Boran to trypanosome infections, as judged by the significantly lower incidence of infection, development of less severe anaemia, fewer requirements for trypanocidal drug treatments, higher growth rates and fewer mortalities. In the area where tsetse challenge was considered low as a result of a tsetse fly control operation using odour-baited traps, only the Maasai Zebu and Orma Boran were compared. No significant differences in the incidence of infection, degree of anaemia or growth rates were observed between the two breeds, but all were significantly different from their counterparts in the high tsetse challenge area. These results suggest that there is variation in resistance to trypanosomosis among Bos indicus cattle breeds that could be exploited as part of the integrated trypanosomosis control programmes in East Africa.
