According to a recent study from the University of Gothenburg in Sweden, the potency of antibiotic resistance evolution in wastewater has been greatly underestimated. The research reveals that wastewater has unique properties that allow resistance genes to start their journey from harmless bacteria
A study from the University of Gothenburg reveals that wastewater environments are more conducive to antibiotic resistance evolution than previously thought, with unique characteristics enabling resistance genes to transfer from harmless to disease-causing bacteria. The research emphasizes the need for attention on waste streams alongside efforts to reduce antibiotic use in humans and animals, in order to prevent the emergence of new antibiotic-resistant bacteria.
The researchers acknowledged that it is not sufficient with antibiotics to drive the process. The species carrying the resistance genes in their chromosome also needs to be present, as well as specific sequences of DNA that could provide the ability to move the resistance genes. “In order to fight antibiotic resistance we cannot focus only on preventing the spread of those types of resistant bacteria that are already in circulation, we also need to prevent or delay the emergence of new ones,” says Fanny Berglund, a researcher at the Sahlgrenska academy at University of Gothenburg, and the lead author of the study.
