Data from: Signatures of positive selection in African Butana and Kenana dairy zebu cattle

Hussain Bahbahani, Bashir Salim, Faisal Almathen, Fahad Al Enzi, Joram M. Mwacharo, Olivier Hanotte & Fahad Al Enezi
Butana and Kenana are two types of zebu cattle found in Sudan. They are unique amongst African indigenous zebu cattle because of their high milk production. Aiming to understand their genome structure, we genotyped 25 individuals from each breed using the Illumina BovineHD Genotyping BeadChip. Genetic structure analysis shows that both breeds have an admixed genome composed of an even proportion of indicine (0.75 ± 0.03 in Butana, 0.76 ± 0.006 in Kenana) and taurine...

Genomic signatures of domestication in Old World camels

Domestication begins with the selection of animals showing less fear of humans. In most domesticates, selection signals for tameness have been superimposed by intensive breeding for economical or other desirable traits. Old World camels, conversely, have maintained high genetic variation and lack these secondary bottlenecks associated with breed development. By re-sequencing multiple genomes from dromedaries, Bactrian camels, and their endangered wild relatives, we show that positive selection for candidate genes underlying traits collectively referred to...

Data from: Laboratory rearing of Anopheles arabiensis: impact on genetic variability and implications for Sterile Insect Technique (SIT) based mosquito control in northern Sudan

Rasha Siddig Azrag, Kamal M. Ibrahim, Colin Malcolm, Elamin El Rayah & Badria El-Sayed
Background: Mosquito colony populations often show significant changes in their population genetic make-up compared to the field populations that were used as founding source. Most of the changes that have been reported are indicators of depletion in the overall genetic diversity of the colony populations. The Sterile Insect Techniques programme of mosquito control that is underway in Northern Sudan uses sterilized males produced from a laboratory-maintained colony population. The genetic diversity of an advanced generation...

Data from: Ancient and modern DNA reveal dynamics of domestication and cross-continental dispersal of the dromedary

Banabazi, Marzook Al-Eknah, Chris Walzer, Bernard Faye, Michael Hofreiter, Joris Peters, Olivier Hanotte & Pamela A. Burger
Dromedaries have been fundamental to the development of human societies in arid landscapes and for long-distance trade across hostile hot terrains for 3,000 y. Today they continue to be an important livestock resource in marginal agro-ecological zones. However, the history of dromedary domestication and the influence of ancient trading networks on their genetic structure have remained elusive. We combined ancient DNA sequences of wild and early-domesticated dromedary samples from arid regions with nuclear microsatellite and...

Data from: First molecular characterization of Echinococcus granulosus (sensu stricto) genotype 1 among cattle in Sudan

Mohamed E. Ahmed, Bashir Salim, Martin P. Grobusch & Imadeldin E. Aradaib
Background: Echinococcus granulosus sensu lato (s.l.) is the causative agent of cystic echinococcosis (CE), which is a cosmopolitan zoonotic parasitic disease infecting humans and a wide range of mammalian species including cattle. Currently, little information is available on the genetic diversity of Echinococcus species among livestock in Sudan. In the present study, fifty (n = 50) hydatid cysts were collected from cattle carcasses (one cyst sample per animal) at Al-kadarou slaughterhouse, Khartoum North, Sudan. DNA...
