A method is described for calculating new infection incidence from monthly field data collected between April 1994 and February 1998 from an average of 770 Ethiopian Highland Zebu cattle maintained under traditional management in the Ghibe valley, southwest Ethiopia and exposed to a high challeng...


Rowlands, G.J.Leak, S.G.A.Peregrine, A.S.Nagda, S.M.Mulatu, W.D'Ieteren, G.D.M.[The incidence of new and the prevalence and persistence of recurrent trypanosome infections in cattle in southewest Ethiopia exposed to a high challenge with drug-resistant parasites]The incidence of new and the prevalence and persistence of recurrent trypanosome infections in cattle in southewest Ethiopia exposed to a high challenge with drug-resistant parasites

Approximately 320 East African Zebu cows over 36 months of age were monitored monthly from 1986 to 1992 in nine village herds in an area of high trypanosomiasis risk in southwest Ethiopia where there was resistance to all available trypanocidal drugs. Cows were individually treated with diminazen...

The new pour-on insecticides that can be used to control tsetse-transmitted trypanosomiasis confer benefits to the owners of the cattle given treatments and other people keeping cattle in areas affected by the control. A study was conducted in southwest Ethiopia to assess farmers' perceptions of ...

In order to assess the effect of tsetse control on livestock productivity, 21 herds of cattle of N'Dama, Baoule and Zebu cross breeds in the region of Boundiali, northern Cote d'Ivoire, were monitored monthly for trypanosome prevalence, packed red cell volume (PCV), body weight and reproductive p...

Tsetse populations and trypanosome prevalence in cattle were monitored from 1986 to 1993 in the Ghibe valley, south-west Ethiopia. From January 1991 to December 1993 between 2000 and 4000 cattle were treated at monthly intervals with a synthetic pyrethroid insecticide, cypermethrin (RS-alpha-cyan...


Leak, S.G.A.Mulatu, W.Rowlands, G.J.D'Ieteren, G.D.M.[A trial of a cypermethrin `pour-on' insecticide to control Glossina pallidipes, G. fuscipes fuscipes and G. morsitans submorsitans (Diptera: Glossinidae) in south-west Ethiopia]A trial of a cypermethrin `pour-on' insecticide to control Glossina pallidipes, G. fuscipes fuscipes and G. morsitans submorsitans (Diptera: Glossinidae) in south-west Ethiopia

Trypansosome infections in approximately 110,000 tsetse of 12 species or subspecies, at sites in six African countries, were studied over various periods from 1983 to 1994. Infection rates ranged from 0.2 percent in Glossina fuscipes quanzensis Pires at a site in Zaire, to 18 percent in Glossina ...

Reports results of a study on the relationships between tsetse challenge and trypanosome prevalence in trypanotolerant and susceptible breeds of cattle. Presents data on tsetse challenge and trypanosome prevalence in N'Dama and Zebu cattle in Zaire, Gabon, Ethiopia and Cote d'Ivoire.


Leak, S.G.A.Colardelle, C.Coulibaly, L.Dumont, P.Feron, A.Hecker, P.D'Ieteren, G.D.M.Jeannin, P.Minengu, M.Minja, S.Mulatu, W.Nankodaba, G.Ordner, G.Rowlands, G.J.Sauveroche, B.Tikubet, G.Trail, J.C.M.[Relationships between tsetse challenge and trypanosome prevalence in trypanotolerant and susceptible cattle]Relationships between tsetse challenge and trypanosome prevalence in trypanotolerant and susceptible cattle

The significance of Glossina fusca group tsetse flies as vectors of cattle trypanosomiasis was examined using biconical traps to survey tsetse populations at one site in Gabon and two sites in Zaire. Mean trypanosome infection rates in G. tabaniformis Westwood over the study period ranged from 8....
