A bacteriophage is a type of virus that infects bacteria. In fact, the word ‘bacteriophage’ literally means ‘bacteria eater,’ because bacteriophages destroy their host cells. A bacteriophage attaches itself to a susceptible bacterium and infects the host cell. Following infection, the bacteriophage hijacks the bacterium’s cellular machinery to prevent it from producing bacterial components and instead forces the cell to produce viral components. Eventually, new bacteriophages assemble and burst out of the bacterium in a process called lysis.

Be aware at present there are insufficient randomised control trials showing success in the usage of phage therapy for the treatment of UTIs.  This is an expensive, as yet unproven, adjunct to conventional antibiotic therapies.
