Descriptor fagos T
Scope note: Serie de 7 fagos virulentos que infectan a E. coli. Los fagos T-pares -T2, T4 (BACTERIÓFAGO T4) y T6- y los fagos T5 se denominan autónomamente virulentos porque interrumpen todo el metabolismo bacteriano durante la infección. Los fagos T1, T3 (BACTERIÓFAGO T3) y T7 (BACTERIÓFAGO T7) presentan una virulencia dependiente, dado que dependen de la continuación del metabolismo bacteriano durante el ciclo lítico. Los fagos T-pares contienen en su ADN 5-hidroximetilcitosina en lugar de la citosina ordinaria.

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.
