The good news: Antibiotics didn’t create antibiotic-resistant bacteria. The bad news: Antibiotic-resistant bacteria is everywhere.
"That evidence is now coming in, and it shows that we’re swimming in a vast reservoir of antibiotic resistance genes. Using a new method called “functional metagenomics,” scientists are searching for resistance genes by collecting bacterial DNA from the environment and testing its function in harmless lab bacteria. Researchers have collected DNA from a wide range of environments, including the human gut, city soil, remote Alaskan wilderness, processed sewage, and even 30,000 year old Beringian permafrost. Antibiotic resistance genes were found in each of these environments."
