medicinal maggots

A writhing mass of maggots in a wound might seem like a good reason to seek medical help. But, reports Carrie Arnold, sometimes it’s the doctors who have put them there, adopting an ancient treatment to help heal painful infected injuries.
Scientists at the North Carolina State University have engineered maggots to express human proteins that are capable of aiding and promoting wound healing. This can have future therapeutic value, by providing a safe and cost-effective means of healing tough-to-treat wounds.
