T-Phages

Medical Definition:	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.
Guide Notes:	coliphages; GEN or unspecified; prefer specifics; do not confuse with T VIRUS see RETICULOENDOTHELIOSIS VIRUS
Previously Indexed:	Coliphages (1966-1979)
