The Q-Slide Mastitis Test is a ready-to-go test that can differentiate between Gram+ and Gram- bacteria, allowing selective, timely mastitis treatment. As roughly 50% clinical mastitis cases need no antibiotic treatment, farmers can save antibiotics, withdrawal time, and reduce the risk of antibiotic resistance. The Q-Slide Test is simple to use; just dip and incubate. First results are to be seen after 4 hours, maximum 24 hours.
