MeSH Heading: T-Phages
Tree Number(s): B04.123.205.891
Unique ID: D013604
RDF Unique Identifier: http://id.nlm.nih.gov/mesh/D013604
Annotation: general or unspecified; prefer specifics; do not confuse with T VIRUS see RETICULOENDOTHELIOSIS VIRUS
Scope Note: A series of 7 virulent phages which infect E. coli. The T-even phages T2, T4; (BACTERIOPHAGE T4), and T6, and the phage T5 are called "autonomously virulent" because they cause cessation of all bacterial metabolism on infection. Phages T1, T3; (BACTERIOPHAGE T3), and T7; (BACTERIOPHAGE T7) are called "dependent virulent" because they depend on continued bacterial metabolism during the lytic cycle. The T-even phages contain 5-hydroxymethylcytosine in place of ordinary cytosine in their DNA.
