My research focus is the epidemiology of zoonotic bacterial agents
in their domestic animal reservoirs. I’m particularly interested in
those agents that cause human food-borne diseases. The long-term
goal of my research is the development of practical measures to
reduce the prevalence of these agents in the animal reservoir as a
means of reducing the risk of human disease.
While a great
deal is known about how these agents act within the human host to
cause disease, much less is known about their behavior in the animal
reservoir(s) populations, which they typically colonize without
evident signs of disease. If factors that influence the prevalence
and dissemination of these agents can be identified, these factors
might be manipulated to reduce human exposures to these dangerous
agents.
I’m
specifically interested in the role of clonal dissemination in the
epidemiology of non-typhoid Salmonella and thermophilic
Campylobacters, the interaction between the E. coli
O157:H7 and their animal hosts and the environment and the
relationship between antimicrobial resistance in Campylobacter
and Salmonella bacteria and the use of antimicrobial drugs in
animal husbandry.
