TB-resistant cows developed using CRISPR

Researchers use modified version of CRISPR technology to insert new gene for bovine tuberculosis resistance into cow genome, with no off-target effects detected.

CRISPR/Cas9 gene editing technology has been used for the first time to successfully produce live cows with increased resistance to bovine tuberculosis (TB), according to new research published in the open-access journal Genome Biology.

Researchers from the College of Veterinary Medicine at Northwest A&F University in Shaanxi, China, used a modified version of the CRISPR gene editing t
