Researchers have determined how harmless E.coli gut bacteria in chickens can easily pick up the genes required to evolve to cause a life-threatening infection. The study, published in the journal Nature Communications, warns that such infections not only affect the poultry industry but could also potentially cross over to infect humans.

“Previously we thought that E. coli became pathogenic by acquiring specific genes from other bugs, often packaged in mobile elements called plasmids. But our study compared the genomes of disease-causing and harmless E. coli in chickens and found that they can 'turn bad' simply by picking up genes from their environment,” said Sam Sheppard from the University of Bath in the UK.

“Bacteria do this all the time inside the guts of chicken, but most of the time the scavenged genes are detrimental to the bacteria so it becomes an evolutionary dead end.” However, there are 26 billion chickens worldwide, representing around 70 per cent of all bird biomass on earth.
