Genetic Find Might Lead to More TB Resistant Cattle

February 26, 2014

Scientists at the University of Edinburgh compared the genetic code of TB-infected animals with that of disease-free cattle and found several genetic signatures associated with TB resistance in the cows that remained unaffected. The researchers used the latest gene identification techniques to compare the genes of healthy and infected female Holstein-Freisians. This study is a follow up a previous study by the same team which showed that some cattle might be more resistant to bovine TB because of their genetic makeup. According to the researchers, the latest finding sheds light on how to improve TB control through selective breeding.
