Genetic changes alter risk of food bug
A DNA study finds that Salmonella variants found in pigs pose different threats to human and animal health""We have seen these types of changes before in variants of Salmonella that have become adapted to specific host species and cause a more invasive disease, including the type of Salmonella that causes typhoid fever in people but does not affect other species," said Professor Rob Kingsley with Quadram Institute and University of East Anglia."
