ine the risk of E. coli O157 transmission from cows to humans, and to evaluate the efficacy of vaccinating cattle.
They found that the risk of E. coli O157 infection is particularly significant when the cattle are super-shedding -- excreting extremely high numbers of bacteria in their faeces for a limited period of time. Vaccines against the bacteria exist that can reduce super-shedding.
Because the currently available vaccines target bacterial shedding rates, the researchers predicted that va
