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.
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.

Structure of phage ΦX174 capsid Schematic drawing of a Sinsheimervirus (aka Phix174microvirus) virion. The phi X 174 (or ΦX174) bacteriophage is a single-stranded DNA virus that infects Escherichia coli.
Schematic drawing of a Φ29 phage virion (cross section and side view). The structure of Φ29 is composed of seven main proteins: the terminal protein (p3), the head or capsid protein (p8), the head or capsid fiber protein (p8.5), the distal tail knob (p9), the portal or connector protein (p10), the tail tube or lower collar proteins (p11), and the tail fibers or appendage proteins (p12*).
A bacteriophage is a type of virus that infects bacteria. Bacteriophage are likely the most numerous "organisms" on Earth [1] [2] The main article for this category is Bacteriophage .
Φ6 (Phi 6) is the best-studied bacteriophage of the virus family Cystoviridae. It infects Pseudomonas bacteria (typically plant-pathogenic P. syringae). It has a three-part, segmented, double-stranded RNA genome, totalling ~13.5 kb in length. Φ6 and its relatives have a lipid membrane around their nucleocapsid, a rare trait among bacteriophages.
A bacteriophage, or phage for short, is a virus that can infect bacteria and archaea, and can replicate inside of them. Phages make up the majority of most viromes and are currently understood as being the most abundant organism. [5]
Bacteriophage Lambda Structure at Atomic Resolution [1] Enterobacteria phage λ (lambda phage, coliphage λ, officially Escherichia virus Lambda) is a bacterial virus, or bacteriophage, that infects the bacterial species Escherichia coli (E. coli). It was discovered by Esther Lederberg in 1950. [2]
