Structural model at atomic resolution of bacteriophage T4 [1] The structure of a typical myovirus bacteriophage Anatomy and infection cycle of bacteriophage T4.. A bacteriophage (/ b æ k ˈ t ɪər i oʊ f eɪ dʒ /), also known informally as a phage (/ ˈ f eɪ dʒ /), is a virus that infects and replicates within bacteria and archaea.
Phage injecting its genome into bacterial cell An electron micrograph of bacteriophages attached to a bacterial cell. These viruses are the size and shape of coliphage T1. Phage therapy, viral phage therapy, or phagotherapy is the therapeutic use of bacteriophages for the treatment of pathogenic bacterial infections.

Assembled major coat protein, exploded view. The virion is a flexible filament (worm-like chain) about 6 nm in diameter and 900 nm long.Several thousand copies of a small (50 amino-acid residues) elongated alpha-helical major coat protein subunit (the product of gene 8, or p8) in an overlapping shingle-like array form a hollow cylinder enclosing the circular single-stranded DNA genome.
In a 1945 study by Demerec and Fano, [4] T7 was used to describe one of the seven phage types (T1 to T7) that grow lytically on Escherichia coli. [5] Although all seven phages were numbered arbitrarily, phages with odd numbers, or T-odd phages, were later discovered to share morphological and biochemical features that distinguish them from T-even phages.

M13 is one of the Ff phages (fd and f1 are others), a member of the family filamentous bacteriophage ().Ff phages are composed of circular single-stranded DNA (), which in the case of the m13 phage is 6407 nucleotides long and is encapsulated in approximately 2700 copies of the major coat protein p8, and capped with about 5 copies each of four different minor coat proteins (p3 and p6 at one ...
This phage-display library is added to the dish and after allowing the phage time to bind, the dish is washed. Phage-displaying proteins that interact with the target molecules remain attached to the dish, while all others are washed away. Attached phage may be eluted and used to create more phage by infection of suitable bacterial hosts. The ...
Mycobacteriophage Bxb1 Structure [1]. A mycobacteriophage is a member of a group of bacteriophages known to have mycobacteria as host bacterial species. While originally isolated from the bacterial species Mycobacterium smegmatis and Mycobacterium tuberculosis, [2] the causative agent of tuberculosis, more than 4,200 mycobacteriophage species have since been isolated from various environmental ...
