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

Serial analysis of gene expression (SAGE) in bovine trypanotolerance: preliminary results [PDF]

Genetics Selection Evolution, 2003
In Africa, trypanosomosis is a tsetse-transmitted disease which represents the most important constraint to livestock production. Several indigenous West African taurine (Bos taurus) breeds, such as the Longhorn (N'Dama) cattle are well known to control ...

Analysis of 206 whole-genome resequencing reveals selection signatures associated with breed-specific traits in Hu sheep. [PDF]

Evol Appl
Abstract As an invaluable Chinese sheep germplasm resource, Hu sheep are renowned for their high fertility and beautiful wavy lambskins. Their distinctive characteristics have evolved over time through a combination of artificial and natural selection. Identifying selection signatures in Hu sheep can provide a straightforward insight into the mechanism

Immunogénétique du taurin Baoulé en pays Lobi (Burkina Faso). I. Environnement de cette population trypanotolérante [PDF]

Revue d’Elevage et de Médecine Vétérinaire des Pays Tropicaux, 1992
L'étude a porté sur 1016 bovins de race taurine Baoulé (Bos taurus) réputée "trypanotolérante". Des enquêtes entomologiques, parasitologiques et immunologiques ont permis de vérifier que les pressions glossiniennes et trypanosomiennes étaient réelles et

Immune Response in Cattle Trypanosomosis and Trypanotolerance: Main Findings and Gaps

Parasite Immunology, Volume 46, Issue 11, November 2024.
ABSTRACT Trypanosome parasites of the genus Trypanosoma cause African animal trypanosomosis, a devastating livestock disease plaguing sub‐Saharan Africa. Unlike many protozoan parasites, these extracellular blood‐borne pathogens directly engage the host's immune system. While the mouse model has provided valuable insights, a comprehensive understanding

Courbe de progestérone plasmatique du cycle oestral chez les races taurines trypanotolérantes de Côte-d'Ivoire

Revue d’Elevage et de Médecine Vétérinaire des Pays Tropicaux, 1991
Pendant 45 jours, du sang a été prélevé quotidiennement sur 12 vaches Ndama et 12 vaches Baoulé cyclées pour doser la progestérone plasmatique. La durée du cycle observée était de 20,4 et 21,4 jours respectivement.

Computational Identification of Master Regulators Influencing Trypanotolerance in Cattle. [PDF]

Int J Mol Sci, 2021
African Animal Trypanosomiasis (AAT) is transmitted by the tsetse fly which carries pathogenic trypanosomes in its saliva, thus causing debilitating infection to livestock health. As the disease advances, a multistage progression process is observed based on the progressive clinical signs displayed in the host’s body.
