Their findings, published in the Proceedings of the National Academy of Sciences (PNAS), show that the huge global expansion of chicken farming has created ideal conditions for the bacterium to spread, mix and acquire new traits that help it survive. Since the 1960s, global chicken numbers have increased sevenfold to about 31 billion birds. Chickens account for about 70% of all bird biomass on Earth today.
