More and more people are falling prey to E. coli infection from tainted spinach. E. coli experts like B. Brett Finlay, an HHMI international research scholar at the University of British Columbia in Canada, can explain how the E. coli bacteria place a death grip on intestinal cells. Finlay's lab determined the molecular structure of E. coli, information that could aid in development of a vaccine for humans, as well as a vaccine for cattle, because E. coli often is transmitted by ground beef. Finlay has been an HHMI international research scholar since the Institute's first competition for Canadian and Latin American scientists in 1991. In 2003, Time magazine named him one of Canada's top five scientists to have influenced health worldwide. Finlay recently won the Flavelle Medal, the Royal Society of Canada's highest honor.
