Salmonella survives better in stomach due to altered DNA

nd survive better and are therefore more infectious: the evolution of a pathogen. Examining which genetic characteristics are present in an infectious Salmonella (in this case the DT104 type) can reveal how this pathogen has become stronger and caused more outbreaks. This information can also be used to make a less dangerous variant of this infectious Salmonella. Such a harmless variant can be used as a vaccine.

Salmonella serovar Typhimurium DT104 is an antibiotic-resistant pathogen that is transmitted via food and is considered to be dangerous for humans. In recent decades the number of infections with this variant has increased in many parts of the world. This research was funded by NWO and contributes to knowledge about the characteristics and behaviour of this dangerous Salmonella.
