They also saw that there was increased salmonella translocated to the tumours.
Lead researcher Jun Sun said: “During infection, salmonella hijacks essential host signalling pathways, and these molecular manipulations may cause oncogenic transformation.
“The current study tells us that more research is needed into the connection between salmonella exposure and colon cancer risk in the USA, and that simply by practising safe food preparation, we can potentially help to protect ourselves.”
Sun’s collaborators in the Netherlands also studied the bacteria in vitro, by combining human cancer cells and pre-cancer cells with the salmonella strain in the lab.
