 | | Phage T4 Enterobacteria phage T4, genus "T4-like Viruses", family Myoviridae, or viruses with 34-170 kbp dsDNA genomes, isometric heads and contractile tails - infects the gram-negative bacterium E coli. |
 | | - Enterobacteria phage λ, genus "λ-like Viruses", family Siphoviridae, a tailed phage with an isometric head and a 49 kbp dsDNA genome - attaches to the maltose receptor on the surface of the E coli cell. |
 | | Although the tail is non-contractile, a DNA injection mechanism similar to that of T-even phages allows entry of DNA into the cell, leaving the capsid behind. |
