Adhesion zones phage adsorption

The core or needle of the phage tail provides a convenient marker for the site of DNA injection on the host cell (Fig. 10). In the experiment of Table II, we counted adsorbed T2 phages which revealed unambiguous contacts between the tail core and the profile of the outer membrane. The data are presented as percentage of phage particles whose tail cores made contact over adhesion zones. The results show that a preferential adsorption. 

After adsorption, the phage is positioned preferentially over the adhesion zones that are formed between the outer and inner membranes.
