Ceftiofur is one of the top selling drug lines of Zoetis, the world’s largest animal health company.It belongs to a class of drugs called cephalosporins; considered critically important in human medicine. Ceftriaxone is part of the same class as antibiotics used to treat pneumonia, meningitis and salmonella.The overuse of one type causes the effectiveness of others in the same class to wane as the organisms adapt to it. Ceftiofur, more than any other antibiotic, sharply increases the amount of antibiotic resistant bacteria in an animal, researchers say. The drugs kill off weaker bacteria, allowing the stronger bacteria to survive and multiply.
