major new research project has been launched at
Some 50 livestock farmers and slaughterhouse employees from
It is hoped the results will provide a better understanding of E. coli
O157 and how some individuals resist the infection which strikes around 1,000
people in the
It may also help explain why the incidence of human E. coli O157 infection is so low in Wales compared to the Grampian region, which has one of the world’s highest rates of the infection.
The study is part of a three year rural economy and land use project
bringing together researchers from across the
“This particular strand will investigate why livestock farmers and
abattoir employees are largely unaffected,” says Dr Prysor
Williams, from the School of the Environment and Natural Resources, at
“Considering 10-40 per cent of cattle herds in the
“This could suggest that the more often you are exposed to the bug, the greater your immunity or your ability to deal with the infection.
“Our study will examine this thinking by testing for antibodies in blood and saliva. That will indicate whether that person has had E. coli O157 in the past.
“We will also test stool samples to see if people are carrying the bug without it actually affecting them, which would suggest they possess a degree of immunity.
“Over 100 farmers from
“We would also like to hear from people who have been infected with E. coli O157 in the past. This will allow us to build a picture of how antibody levels and associated immunity decrease with time.”
