Do our medicines boost pathogens?

Scientists of the Institute of Tropical Medicine (ITG) discovered a parasite that not only had developed resistance against a common medicine, but at the same time had become better in withstanding the human immune system. With some exaggeration: medical practice helped in developing a superbug. For it appears the battle against the drug also armed the bug better against its host. "To our knowledge it is the first time such a doubly armed organism appears in nature", says researcher Manu Vanaerschot, who obtained a PhD for his detective work at ITG and Antwerp University. "It certainly makes you think."
