Researchers at Tohoku University have made an interesting discovery that provides a boost to the immune system of birds. They found that B-cell development, which forms part of the immune system, occurs outside the bursa of Fabricius, the organ where scientists previously thought B-cell development exclusively occurred. The findings paint a clearer picture of the birds’ immune system at a time when antimicrobial resistance has affected livestock and poultry production across the globe.
