Research reveals key challenge for Campylobacter vaccine

New research has suggested that the immune response of broilers does not develop fast enough to fight off campylobacter present in the gut. In what was the first study of functional immunity to campylobacter in chicken, researchers found antibodies play a role in the clearance of the bacteria in the gut. But, crucially, it fails to develop sufficiently in the lifespan of commercial broiler birds. The response is also not sufficient to remove the bug from the gut entirely – just to prevent i
