Dr. Besser’s primary research is in:

  • Reducing human disease risks by developing practical measures to reduce the prevalence of human food-borne and zoonotic disease agents in animals.
  • Improving the understanding of the ecology and epidemiology of zoonotic agents in animal reservoir populations and the environment.
  • Use of antimicrobial drugs in animal husbandry while studying enterohemorrhagic E. coli, non-typhoid Salmonella,thermophilic Campylobacter species, and antimicrobial resistance.
