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.
A culture of bacteria infected by bacteriophages, the "holes" are areas where the bacteria have been killed by the virus. The culture is 10cm in diameter. Phage typing is a phenotypic method that uses bacteriophages ("phages" for short) for detecting and identifying single strains of bacteria. [1]
Applying bacteriophages directly to the mucosa targets the site of infection with minimal systemic exposure, leading to a localized immune response. [132] Injecting bacteriophages into muscle tissue introduces them to a larger number of macrophages in the muscle and regional lymph nodes. [133]
Gamma phage, an example of virus particles (visualised by electron microscopy) Virology is the scientific study of biological viruses.It is a subfield of microbiology that focuses on their detection, structure, classification and evolution, their methods of infection and exploitation of host cells for reproduction, their interaction with host organism physiology and immunity, the diseases they ...
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. [6]
A coliphage is a type of bacteriophage that infects coliform bacteria such as Escherichia coli. Coliphage originate almost exclusively from human feces and from other warm-blooded animals. [ 1 ] When certain circumstances are met, such as a large number of susceptible hosts present at the right temperature, they can only partially replicate in ...
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 ...
