In your food, bad. In a shot, good.
The salmonella germ that causes food poisoning may hold the key to development of a vaccine which could eradicate typhoid fever.
While typhoid vaccines already exist, researchers say they could be made more effective. Studies published in the journal Nature, show the genes of both typhoid and salmonella bacteria are 99% identical and if the salmonella bacteria can be modified, it could help eradicate typhoid.
Salmonella bacteria already are modified to carry vaccines against other disease and to deliver anti-cancer drugs directly to tumors deep inside the body.
