	The trick is to use only partial phage particles.  This works 
because of the phenomenon of "LYSIS-FROM-WITHOUT" . It is possible to 
clone the host recognition peptide for some phage particles and use this 
in large concentrations to destabilize the bacterial membrane integrity.  
That way, only a specific protein will be introduced into the patient.....
