Onderstepoort Journal of Veterinary Research, 2005 Studies on the trypanotolerance of Orma Boran X Maasai Zebu (Orma Zebu) crossbred cattle (F1 progeny) and pure-bred Maasai Zebu contemporaries were carried out in Nguruman, south western Kenya. The two groups were monitored from birth for a period of 2

Trypanotolerance in East African Orma Boran cattle
Veterinary Record, 1985 Comparative studies on two types of large East African zebu (Bos indicus) Boran cattle, on a beef ranch in Kenya, have indicated that a Boran type bred by the Orma tribe has a superior response to tsetse fly challenge. The Orma Boran when compared with an improved Boran was found to have lower trypanosome infection rates and, when untreated, better ...

Caractéristiques spermatiques du taureau Baoulé (Bos taurus taurus ) au Burkina Faso
Revue d’Elevage et de Médecine Vétérinaire des Pays Tropicaux, 1989 Cette étude a porté sur 9 taureaux Baoulé. Une forte incidence pathologique en saison humide perturbe l'ensemble des caractéristiques spermatiques. Ces caractéristiques, pour les animaux sains, sont les suivantes : volume = 2,4 plus ou moins 1,5 ml ...

Host Susceptibility to African Trypanosomiasis: Trypanotolerance
, 1982 Publisher Summary The exploitation of genetic resistance to disease is an important consideration in livestock development programs, where conventional disease control measures are not effective or are too costly. Such an approach may be directly applicable to African animal trypanosomiasis.

Marker-assisted introgression of Trypanotolerance QTL in mice
Mammalian Genome, 2005 A marker-assisted introgression (MAI) experiment was conducted to use genetic markers to transfer each of the three trypanotolerance QTL from a donor mouse strain, C57BL/6, into a recipient mouse strain, A/J. We used a backcross strategy that consisted of selecting two lines, each carrying two of the donor QTL alleles through the backcross (BC) phase ...

A comparative study on the susceptibility of male and female albino mice to Trypanosoma brucei brucei [PDF]
Journal of Vector Borne Diseases, 2005 Background & objectives: Trypanosomiasis has remained a major set-back in the development oflivestock farming in tropical Africa. Thus the need for ascertaining the trypanotolerant levels ofdomestic animal breeds and possible improvement on them cannot ...

Trypanosomiasis and trypanotolerance in cattle: A role for congopain?
Parasitology Today, 1994 A Trypanosoma congolense cysteine protease (congopain) elicits a high IgG response in trypanotolerant but not in trypanosusceptible cattle during primary infections. As discussed here by Edith Authié, this observation suggests that congopain, like other parasite cysteine proteases, may play a role in pathogenicity and that more efficient immune ...
