Biological Warfare

Scientists at the Universities of Nottingham and Maastricht have engineered a strain of bacteria that may be able to fight cancer!

Clostridium sporogenes are anaerobic soil dwellers which cannot survive in the presence of oxygen.   Researchers have genetically modified these bacteria so that they produce an enzyme that activates a cancer drug.  It turns out that the centers of solid cancer tumors contain very little oxygen.  Researchers hope to inject cancer patients’ tumors with the engineered Clostridium spores, which would not survive in the rest of the oxygen-rich body.   After a tumor is infected with the Clostridium, a patient would also be More >
