The T4 virus initiates an Escherichia coli infection by binding OmpC porin proteins and lipopolysaccharide (LPS) on the surface of E. coli cells with its long tail fibers (LTF). [16] [17] A recognition signal is sent through the LTFs to the baseplate. This unravels the short tail fibers (STF) that bind irreversibly to the E. coli cell surface.

The virus attaches to the host cell using its terminal fibers, and uses viral exolysin to degrade the cell wall enough to eject the viral DNA into the host cytoplasm via contraction of its tail sheath. DNA-templated transcription is the method of transcription. The virus exits the host cell by lysis, and holin/endolysin/spanin proteins. Once ...
[101] [82] From 78 recent cases of treatment of biofilm infections, 96% of patients saw clinical improvement using phage therapy, and 52% of patients saw complete symptom relief or a full expungement of the affecting bacteria. [101] Biofilm infections are very challenging to treat with antibiotics.

Schematic drawings of a phage virion (species Escherichia virus T4, cross sections and side view) Viruses in Tevenvirinae are non-enveloped, with head-tail geometries. These viruses are about 70 nm wide and 140 nm long. Genomes are linear, around 170-245kb in length. The genome codes for 300 to 415 proteins. [3]
