Antimicrobial drug resistance, future

Resistance of pathogens to antimicrobial treatment is a major concern in veterinary medicine, just as in human medicine. Antimicrobial resistance negatively impacts both the current use and future development of pharmaceuticals for animals. For sick animals, antimicrobial resistance directly impairs the success of treatment to control disease. This can affect the prognosis and suffering for an individual animal and often the productivity, survival, and economic returns for an entire herd. Resistance may make it difficult to find effective, already approved drugs as active controls for preapproval clinical trials. The ability of resistant micro-organisms to move between humans and animals raises serious public health concerns.
