As the culprit behind one million cases of food poisoning and 380 deaths every year, Salmonella is definitely bad news for the stomach. But what if it’s possible to turn Salmonella into one of the good guys? That’s exactly what researchers from Duke University wanted to achieve when they genetically engineered a strain of Salmonella into brain tumor munchers.
Salmonella Has Been Genetically Engineered to Consume Brain Tumors
The tweaks made the Salmonella into Purine-deficient bacteria. Purine is an amino-acid that’s abundantly found in tumors. So, once these modified Salmonella were injected into the brain, they dug deep into the tumors and started rapidly multiplying. At the same time, they have also been designed to produce two compounds in low-oxygen environments, such as the inside of tumors. These added compounds, Azurian and p53, cause cells to self destruct, killing both the tumors and the Salmonella bacteria.

The recall includes Lactalis' Picot, Milumel and Taranis brands. The head of the French dairy Lactalis on Sunday confirmed that its products are being recalled from countries across Europe, Africa, Latin America and Asia after salmonella was discovered at one of its plants last month. The United States, Britain and Australia were not affected.
Quentin Guillemain, president of the victim's association of the Lactalis baby milk products contaminated with Salmonella gives a press conference, on January 12, 2018 in Paris.
Emmanuel Besnier told weekly newspaper Le Journal du Dimanche that his family company, one of the world's biggest dairies, would pay damages to "every family which has suffered a prejudice." The paper said 35 babies were diagnosed with salmonella in France, one in Spain and a possible case in Greece.
Salmonella can cause severe diarrhea, stomach cramps, vomiting and severe dehydration. It can be life-threatening, especially in young children. Lactalis officials have said they believe the contamination was caused by renovation work at their Celia factory in Craon, in northwest France. France's agriculture minister said products from the factory will be banned indefinitely during the investigation.
