A number of Nobel Prize winners worked with virus T4 or T4-like viruses including Max Delbrück, Salvador Luria, Alfred Hershey, James D. Watson, and Francis Crick. Other important scientists who worked with virus T4 include Michael Rossmann, Seymour Benzer, Bruce Alberts, Gisela Mosig, [48] Richard Lenski, and James Bull.
Phage therapy, viral phage therapy, or phagotherapy is the therapeutic use of bacteriophages for the treatment of pathogenic bacterial infections. [ 1 ] [ 2 ] [ 3 ] This therapeutic approach emerged at the beginning of the 20th century but was progressively replaced by the use of antibiotics in most parts of the world after the Second World War .
Escherichia coli strains carrying nonsense suppressor genes had a central role in the early work on bacteriophage genetics. [10] In particular, E. coli strains carrying amber suppressors (suppressors of the UAG nonsense codon) enabled the isolation and propagation of bacteriophage T4 mutants defective in phage assembly, morphogenesis, DNA replication, DNA repair and genetic recombination and ...
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 display cycle. 1) fusion proteins for a viral coat protein + the gene to be evolved (typically an antibody fragment) are expressed in bacteriophage. 2) the library of phage are washed over an immobilised target. 3) the remaining high-affinity binders are used to infect bacteria. 4) the genes encoding the high-affinity binders are isolated.
Lysis inhibition: T4-like phages have two genes, rI and rIII, that inhibit the T4 holin, if the infected cell undergoes super-infection by another T4 (or closely related) virion. Repeated super-infection can cause the T4 infection to continue without lysis for hours, leading to accumulation of virions to levels 10-fold higher than normal.

Research Styles in Virus Studies in the Twentieth Century: Controversies and the Formation of Consensus. Doctoral Thesis, University of Limburg. (note that though this is a thesis, it is of sufficient general interest toward addressing issues in the history of bacteriophagy as to warrant inclusion in this list)
