WebIt provides the means whereby an infected bacterium can repel the invading bacteriophage. When a phage attempts to grow on a new host species of bacterium, its efficiency is only a fraction of a percent of that shown on its normal host. This is a major factor in determining the host range of bacteriophage. Those few phage that do grow produce ...
