In the cytoplasm, the satellite virus hijacks the morphogenesis machinery of its helper virus to produce its progeny. Virophages are small, double-stranded DNA viral phages that require the co-infection of another virus. The co-infecting viruses are typically giant viruses. Virophages rely on the viral replication factory of the co-infecting ...
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.
Until the discovery of Pandoravirus in 2013, it was the largest known virus, with its 440 nm diameter capsid being as large as some small bacteria. The capsid is enclosed in bacterial-like capsular material 75–100 nm thick. Credit: Chantal Abergel (10 October 2011) Portal:Viruses/Selected picture/27
The virus will replicate and spread, generating regions of cell destruction known as plaques. For example, Vero cell or other tissue cultures may be used to investigate an influenza virus or coronavirus, while various bacterial cultures would be used for bacteriophages. [1] [2] Counting the number of plaques can be used as a method of virus ...
The CDC issued a warning about flesh-eating bacteria vibrio vulnificus after six people died on the East Coast. Infectious disease experts explain the risks.
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 ...
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 .
The CDC estimates that vibriosis causes 80,000 illnesses in the U.S. Around 52,000 of those cases are from consuming contaminated food.
