The majority of chickens in sub-Saharan Africa are indigenous ecotypes, well adapted to the local environment and raised in scavenging production systems. Although they are generally resilient to disease challenge, routine vaccination and biosecurity...

Polymorphism of the MHC-DQA2 gene in the Chios dairy sheep population and its association with footrot (2013)
Journal Article
Gelasakis, A. I., Arsenos, G., Hickford, J., Zhou, H., Psifidi, A., Valergakis, G. E., & Banos, G. (2013). Polymorphism of the MHC-DQA2 gene in the Chios dairy sheep population and its association with footrot. Livestock Science, 153(1-3), 56-59. https://doi.org/10.1016/j.livsci.2013.02.011

The objectives of this study were to assess (i) the nature and frequency of polymorphism of the DQA2 gene in Chios dairy sheep and (ii) if it is associated with footrot prevalence in the population. A total of 20 DQA2 alleles/haplotypes and 78 genoty... Read More about Polymorphism of the MHC-DQA2 gene in the Chios dairy sheep population and its association with footrot.
