Taking things a step further, the research has also shown that the newly engineered bacteria in the patient could also be programmed to self-destruct after leaving the body. The decrease in temperature from the inside the body to the outside world, could activate a genetic switch to destruct. One of studies have shown that the engineered bacteria can release a tumor destroying drug, hemolysin directed to the tumor. The mechanism of genetically modifying the bacteria involves two proteins, one from a virus, bacteriophage and one from Salmonella. Both of the proteins bind to the DNA to turn the genetic code on or off in response to temperature.
The idea that medicine can be dispensed from a bacteria is quite genius and the fact that it can also be temperature controlled is out of this world. The scientists working on this seem to have put a lot of time into every last detail of this creation and I cannot wait to see how it affects our world. I wonder how many different conditions this can help after more research is done.
