Bad news: Salmonella carries a newly discovered antibiotic resistance gene - life short science news

When scientists analyzed the genome of Salmonella bacteria, they discovered a gene, named mcr-9, that renders bacteria resistant to the last resort antibiotic colistin.

Colistin has been designated a highest priority antibiotic by the World Health Organization, and is given when other antibiotics are without effect.

As mcr-9 can jump from bacteria species to species, this gene may impose problems for our health as more bacteria may become resistant to antibiotics, even to colistin.
