Study Traces Back the Evolutionary History of Antibiotic Resistance

Study Traces Back the Evolutionary History of Antibiotic Resistance

Gothenburg scientists have traced back the evolutionary history of antibiotic resistance genes.
In almost all cases where an origin could be determined, the gene started to spread from bacteria that, themselves, can cause disease.
While human DNA is only passed down from parent to child, bacteria also have the habit of sharing some of their genes across species. This often applies to genes that make the bacteria resistant to antibiotics.
‘The use and overuse of antibiotics provide an advantage to those bacteria that have acquired resistance genes, thus further promoting the spread of resistance and making it more difficult to treat infections. This development threatens large parts of modern healthcare.’ ....
