Another strategy is to ambush the bacteria with an unlikely ally: viruses. Vincent Fischetti at Rockefeller University is enlisting the help of bacteriophages, viruses that infect only bacterial cells, leaving human ones alone. They hijack the bacterium's genetic machinery and within minutes start to pump out hundreds of copies of themselves. When enough progeny build up inside the cell, the phages produce an enzyme that chews through the cell wall, causing it to explode with the force of a popping champagne cork and spew out the viral intruders...

...After about 45 minutes, the viruses produce a lytic enzyme, which causes the bacterial cell wall to burst...
