The article (took a bit of digging to find it) says that it is a weakend
form of Salmonella, and "the unarmed bacteria by themselves have shown good
anti-tumor activity in animal models." Thus even without a specific
chemotherapy gene inserted it does a good job of making the cancer sick.

In order to *keep* the bacteria weakened, I'd suggest always growing it in
the presence of a key nutrient that had been removed from its own synthetic
ability- then the nutrient could be administered to the patient to keep the
infection alive, and removed at the end of therapy. Followed by a good
dose of an antibiotic :)
