Medical Definition of T-phages
1. 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. (12 Dec 1998)
