Bacteria that live in soil and on people have extensive antibiotic-destroying genes

The latest generation of tetracyclines - a class of powerful, first-line antibiotics - was designed to thwart the two most common ways bacteria resist such drugs.

Some of these genes confer the power to destroy all tetracyclines, including the latest generation of these antibiotics.
