Resistance to antibiotics is a serious threat to public health. The fewer antibiotics uses in humans and animals – and the more precisely they are put to use, the better. For cows, mastitis is a potentially fatal mammary gland infection that is also the most common in dairy cattle. With emma , a complete diagnostic solution developed by ender, a rapid molecular diagnostic tool for the evidence-based treatment of mastitis in dairy cows is in its pilot phase. By using emma, up to 40% of all antibiotic treatements can be avoided, reducing the ripple-effect risk of antibiotic resistance significantly. At the same time, it saves farmers considerable costs and promotes healthier bovines.
