Different species of bacteria in each other’s environments can share genetic material, thereby inheriting each other’s resistance to broad-spectrum antibiotics. This is what scientists from the University of Nottingham discovered in collaboration with Chinese colleagues.
The scientists examined the presence of Escherichia coli (E.coli) and Salmonella enterica, both of which have high levels of drug resistance, in five poultry farms and in four slaughterhouses in five poultry farms.
Research shows that E. coli and Salmonella enterica when present together in the intestines of chickens contain higher levels of antibiotic-resistant material than when these species occur separately.

Tania Dottorini from the University of Nottingham, the study’s lead researcher, said: “These bacterial species can share genetic material both within and potentially between species, leading to the spread of resistance.”
For this reason, according to Dottorini, these bacteria can adapt and share their genome in the same environment and therefore in the same host. According to the researcher, this research, which she says has never been done on such a large scale before, provides new insights for a targeted resistance approach.
