The future of anti-infective products in animal health

Thomas R. Shryock

The discovery, development and marketing of animal health anti-infective products are at an important crossroads. Traditional anti-infective products include antibiotics, parasiticides and vaccines, which are administered to either food production or companion animals. The convergence of market conditions, new regulatory guidance, political decisions and food safety concerns has led to a redirection of research away from traditional antibiotics and towards other products that have an increased probability of acceptance in the marketplace and shareholder return.
