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...

The prevalence of ixodid ticks and trypanosomosis of camels was studied in the semi-arid rangelands of southern Ethiopia between 1995 and 1996. A total of 24077 ticks were collected from 510 camels aged between 6 months and 15 years. Eleven species of ticks were identified. Rhipicephalus pulchell...

A monoclonal antibody (MAb)Tv27 employed in an antigen-detection enzyme immunosorbent assay (Ag-ELISA) for diagnosis of Trypanosoma vivax infection was shown to react with a T. vivax-specific protein of an approximate molecular weight of 10 kDa. This protein is diffusely distributed throughout th...

N'Dama (Bos taurus) cattle are known to tolerate trypanosome infections, developing less severe anemia and lower parasitemia, compared to Boran (Bos indicus) cattle. Young calves were also reported to be more resistant to trypanosomiasis than adult cattle. To expore the basis for this resistance,...

Trypanosomiasis is a serious constraint to livestock production in sub-Saharan Africa. Some breeds of cattle are genetically more resistant to the pathogenic effects of trypanosome infection. We measured B-cell activation and the quantity and isotype of antibody produced at the cellular level in ...

A comparison of T-cell-mediated immune responses in trypanotolerant N'Dama and susceptible Boran cattle during primary infection with tsetse-transmitted Trypanosoma congolense was conducted to assess whether different patterns of T-cell activation occurred during trypanosome infection. Proliferat...
