Antibiotic resistance is possible because bacteria are able to exchange genetic material through a process known as bacterial conjugation. In one experiment, resistance to tetracycline (a commonly used antibiotic) was studied in Escherichia coli by introducing a tetracycline-resistant bacterium to a tetracycline-sensitive strain. The resistant bacterium’s genome contained a protein called an “efflux pump”, a polypeptide that localizes to the cell membrane and expels certain small molecules from the cell.
Using fluorescent marking, researchers observed the DNA encoding one specific efflux pump in between a resistant bacterium and a sensitive bacterium. With livecell microscopy, they tracked the fluorescence to see how the DNA migrated from one cell to another and how it was incorporated and expressed in the recipient bacterium.
