Kansas State researching Salmonella and E.coli
A team of seven researchers and six collaborators at
Kansas State University are embarking on studies on E. coli 0157 and
"It's becoming more and more difficult to study these pathogens because you
have to be a jack of all trades," said T.G. Nagaraja, professor of diagnostic
medicine pathobiology at K-State's College of Veterinary Medicine.
Nagaraja leads a research group that includes epidemiologists, molecular
biologists, production animal medicine experts and feedlot nutritionists.
For the past five years, Nagaraja has been leading the team on an E. coli
0157 research project supported by the US Department of Agriculture that goes
back more than a decade at K-State.
On-farm intervention strategies
The research focuses primarily on dealing with the bacteria in cattle -
however, the bacteria also can be found in pigs and poultry. "Our goals are
fairly simple," Nagaraja said. "We want to understand the ecology of E. coli
0157 in cattle and come up with practical, on-farm intervention
Narayanan is also working to develop a rapid, molecular-based testing
method for Salmonella that is more accessible. To find out the serotype of the
Salmonella, veterinarians and researchers have to send samples to a laboratory
The research team is studying antimicrobial resistance with the hopes of
preventing foodborne pathogens from becoming more dangerous to humans and
Nagaraja said that in the future the research team will pursue the goal of
eliminating 0157 and Salmonella.
