Antibiotics are common therapeutic tools used in treatment and prevention of infections in both humans and animals. However, excessive and indiscriminate use of antibiotics in human healthcare and livestock production in the past few decades resulted in microbes that are resistant to these crucial antibiotics. As a result, treatments and therapies to antibiotic resistant infections are getting limited, longer, expensive and less safe. Researchers at Purdue veterinary medicine conduct both basic and translational research to tackle the crisis of antimicrobial resistance.

It is difficult to imagine an issue that summarizes the principles of One Health more than antimicrobial resistance does. Antimicrobial resistance does not recognize geographic or human-animal borders and addressing the rising threat of antimicrobial resistance requires a One Health-driven engagement. Our research is focused on developing new antimicrobials and on improved delivery of drugs for the treatment of infectious diseases that affect both humans and animals. The group also is developing an early detection and identification of a single bacterium/fungus in a complex environment. This development will shift the paradigm of diagnosis from a time-consuming, cultivation-dependent procedure to a culture-independent, in situ approach. Further clinical translation of the proposed technology would save patients’ lives with the early diagnosis of infection and accurate profiling of a pathogen’s susceptibility to antimicrobials.

Dr. Narayanan’s research focuses on cause and spread of antimicrobial resistance in gut microflora and food borne pathogens like E . Coli, Enterococcus and Salmonella using cattle feedlot industry as a model. His lab researches on developing new tools and practices to help reduce the use of antibiotics in food animals, which in turn affects human and environmental health through reduced spread of antibiotic resistance. Efforts are under way to replace antibiotic usage for important cattle diseases (eg. liver abscesses) with vaccines.
