Autor: Codjia, V. Mulatu, W. Majiwa, P.A.O. Leak, S.G.A. Rowlands, G.J. Authié, E. D'Ieteren, G.D.M. Peregrine, A.S.

Blood samples were collected from parasitaemic cattle in the Ghibe Valley, Ethiopia, frozen in liquid nitrogen and transported to Nairobi, Kenya. Twelve of the stabilates were inoculated into individual Boran (Bos indicus) calves and characterised for their sensitivity, in turn, to diminazene ace...

Journal Article 1993

Autor: Rowlands, G.J. Mulatu, W. Authie, A. D'Ieteren, G.D.M. Leak, S.G.A. Nagda, S.M. Peregrine, A.S.

An average of 840 East African Zebu cattle from nine herds in the Ghibe Valley, southwest Ethiopia were monitored from 1986 to 1990. Each month blood samples were collected from analysis of packed red cell volume and detection of trypanosomes. Animals were found to be parasitaemic and with a PCV ...

Journal Article 1994

Autor: Rowlands, G.J. Mulatu, W. Authié, E. D'Ieteren, G.D.M. Leak, S.G.A. Nagda, S.M.

Approximately 390 East African Zebu calves from birth to 3 years of age and their dams 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. Cattle were individua...

Autor: Rowlands, G.J. Teale, A.J.

This workshop was conceived in recognition of the fact that, over the years, a great deal of research has been conducted on trypanotolerance. With the advent of new and powerful means to identify markers and genes controlling traits of interest, and with the developments in animal breeding bringi...

Autor: Peregrine, A.S. Mulatu, W. Leak, S.G.A. Rowlands, G.J.

In 1986 a project was set up to determine the constraints to production of Zebu cattle under trypanosomiasis risk in the Ghibe valley. Approximately 1800 East African Zebu cattle (EAZC) were resident within the Ghibe valleey during the experimental period (1986 - 1992) and were maintained under t...

The objective of this study was to apply transition models to distinguish between factors associated with both incident and persistent trypanosome infections. Data collected from 1561 cattle were analyzed from a long-term study involving 8 herds in which both trypanosome infections (a total of 56...

Journal Article 1999

Autor: Rowlands, G.J. Mulatu, W. Leak, S.G.A. Nagda, S.M. D'Ieteren, G.D.M.

A tsetse control campaign was started in January 1991 using a synthetic pyrethroid cypermethrin `pour-on' applied monthly to cattle exposed to high levels of drug-resistant trypanosomes in the Ghibe valley of southwest Ethiopia. In December 1992, a cost-recovery scheme was introduced, and thereaf...

This study illustrates how productivity impacts resulting from livestock research can be measured using a herd simulation model, how the results of this model can be extended spatially using geographic information systems (GIS) to determine the potential increase in livestock production that woul...

Journal Article 2001

The TNF-alfa gene on mouse chromosome MMU17 is among the candidates for the trypanosomosis resistance QTG Tirl. Tit t has the largest effect of those loci so far detected which influence degree of resistance to murine trypanosomosis caused by Trypanosome congolense infection. We therefore studied...
