Trypanotolerance in Small Ruminants of Sub-Saharan Africa
Trends in Parasitology, 2009 Although a lot of information is currently available on trypanotolerance in cattle, until recently the trypanotolerant nature of small ruminants was not well known. Trypanotolerance in small ruminants is less pronounced than in cattle and should be considered as resilience rather than resistance.

The Genetics of Trypanotolerance in Cattle: A Review
Tropical Veterinarian, 2003 Trypanosomosis is a major recognized factor limiting livestock productivity. Control of the disease has explored the use of drugs, vector and the farming of trypanotolerant livestock in order to enhance productivity. However, there are documented difficulties with each of the methods.

Combatting African Animal Trypanosomiasis (AAT) in Livestock: The Potential Role of Trypanotolerance [PDF]
Veterinary Parasitology, 2016 African Animal Trypanosomiasis (AAT) is endemic in at least 37 of the 54 countries in Africa. It is estimated to cause direct and indirect losses to the livestock production industry in excess of US$ 4.5 billion per annum.

This chapter describes the meaning of trypanotolerance and its implication as used with trypanotolerant livestock that are known and studied for many years in West Africa. This trait is observed in many West African breeds of cattle that survive in areas of tsetse fly challenge where the humped zebu cannot.

Trypanotolerance : an individual not a breed character
Acta tropica, 1983Ten animals from a reputedly trypanosensitive bovine breed, the Zebu, and ten from a reputedly trypanotolerant breed, the Baoulé, were exposed to natural trypanosome challenge in an area of high Glossina density. The ten Zebus and five of the Baoulés died within 6 to 11 weeks with heavy parasitaemia and severe anaemia.

Serial analysis of gene expression (SAGE) in bovine trypanotolerance
, 2002 In central and sub-Saharan Africa, the most important constraint to livestock production is trypanosomosis. This tsetse-transmitted disease is an important risk for about 60 millions cattle spread over 7 million km2. Several indigenous West African taurine (Bos Taurus) breeds, such as longhorn (N'Dama) or shorthorn (Baoule) cattle are known to control ...

Parasitology Today, 1987
Genetic resistance to disease and its use in domestic livestock usually ranks last, if at all, amongst preferred disease control measures - usually preceded by measures such as chemotherapy, vector control and vaccination. Thus, interest in genetic resistance is often a reflection of dissatisfaction with other control strategies, and the current ...

Lack of haplotype structuring for two candidate genes for trypanotolerance in cattle
Journal of Animal Breeding and Genetics, 2015SummaryBovine trypanotolerance is a heritable trait associated to the ability of the individuals to control parasitaemia and anaemia. The INHBA (BTA4) and TICAM1 (BTA7) genes are strong candidates for trypanotolerance‐related traits. The coding sequence of both genes (3951 bp in total) were analysed in a panel including 79 Asian, African and European ...
