Some Biochemical Perturbations May Modify the Understanding of Trypanotolerance in the West African Dwarf Sheep Infected With and [PDF]

Clinical Pathology, 2020
Trypanosomes are single-celled protozoa that cause severe diseases in both humans and livestock in sub-Saharan African countries. The disease in the West African Dwarf (WAD) sheep is often neglected due to the issue of trypanotolerance. The current study

Genomic insights into the population structure and genetic diversity of Ugandan indigenous cattle [PDF]

Animal Genetics, Volume 56, Issue 6, December 2025.
Abstract Domestic cattle in Africa can be categorized as either taurine (Bos taurus) or indicine (Bos indicus) based on their domestication histories from the extinct aurochs (Bos primigenius). Close to 150 breeds of indigenous cattle are estimated to exist in Africa and have a complex mixture of B. taurus and B. indicus ancestries.

Major differences in the dynamics of haematological and biochemical variables between trypanotolerant and susceptible cattle during Trypanosoma congolense infection [PDF]

BMC Veterinary Research
Background Animal African Trypanosomosis, caused by protozoan blood parasites mainly transmitted by Glossina, is a threat to livestock health in Africa. Whilst African zebu and European taurine suffer from trypanosomosis, West African taurine, such as N ...

Identification of Candidate Signature Genes and Key Regulators Associated With Trypanotolerance in the Sheko Breed [PDF]

Frontiers in Genetics, 2019
African animal trypanosomiasis (AAT) is caused by a protozoan parasite that affects the health of livestock. Livestock production in Ethiopia is severely hampered by AAT and various controlling measures were not successful to eradicate the disease.

Analysis of pooled genome sequences from Djallonke and Sahelian sheep of Ghana reveals co-localisation of regions of reduced heterozygosity with candidate genes for disease resistance and adaptation to a tropical environment [PDF]

BMC Genomics, 2019
Background The Djallonke sheep is well adapted to harsh environmental conditions, and is relatively resistant to Haemonchosis and resilient to animal trypanosomiasis. The larger Sahelian sheep, which cohabit the same region, is less well adapted to these

Candidate signatures of positive selection for environmental adaptation in indigenous African cattle: A review

Animal Genetics, Volume 54, Issue 6, Page 689-708, December 2023., 2023
AbstractEnvironmental adaptation traits of indigenous African cattle are increasingly being investigated to respond to the need for sustainable livestock production in the context of unpredictable climatic changes. Several studies have highlighted genomic regions under positive selection probably associated with adaptation to environmental challenges ...

Biphasic survival analysis of trypanotolerance QTL in mice [PDF]

Heredity, 2008
A marker-assisted introgression (MAI) experiment was conducted to transfer trypanotolerance quantitative trait loci (QTL) from a donor mouse strain, C57BL/6, into a recipient mouse strain, A/J. The objective was to assess the effect of three previously identified chromosomal regions on mouse chromosomes 1 (MMU1), 5 (MMU5) and 17 (MMU17) in different ...

Ethiopian indigenous goats offer insights into past and recent demographic dynamics and local adaptation in sub‐Saharan African goats

Evolutionary Applications, Volume 14, Issue 7, Page 1716-1731, July 2021., 2021
Abstract Knowledge on how adaptive evolution and human socio‐cultural and economic interests shaped livestock genomes particularly in sub‐Saharan Africa remains limited. Ethiopia is in a geographic region that has been critical in the history of African agriculture with ancient and diverse human ethnicity and bio‐climatic conditions.

Population structure, inbreeding and admixture in local cattle populations managed by community‐based breeding programs in Burkina Faso

Journal of Animal Breeding and Genetics, Volume 138, Issue 3, Page 379-388, May 2021., 2021
Abstract High‐throughput genomic markers provide an opportunity to assess important indicators of genetic diversity for populations managed in livestock breeding programs. While well‐structured breeding programs are common in developed countries, in developing country situations, especially in West Africa, on‐farm performance and pedigree recordings ...

Prevalence of Bovine Trypanosomosis and Its Associated Risk Factor in Hawa Galan District, Kelem Wollega Zone of Ethiopia

Veterinary Medicine International, Volume 2021, Issue 1, 2021., 2021
An analytical cross‐sectional study was performed between November 2015 and April 2016 at Hawa Galan woreda, Kelem Wollega Zone, Oromia Region, Ethiopia, to estimate the proportion of cattle with trypanosomosis and to evaluate the elements associated with the prevalence of bovine trypanosomosis.
