Caption for May 1997 Agricultural Research magazine article, "Heterophils to the Rescue!" They're the Royal Canadian Mounties of the immune system-the heroes who show up in the nick of time-and they take on all bacterial invaders, be they salmonella, listeria, pasteurella, or E. coli. They're infection-fighting white blood cells called heterophils, and poultry immunologist Michael Kogut has found a way to make them do his bidding to protect young poultry.
