The T stands for "tadpole."
B-cells are named after the first location in which they were observed, the Bursa of Fabricius.
In the book "Phages - Their Role in Bacterial Pathogenesis and Biothechnology", page 11 chapter 1:
"T is for Type"
It is a virus.
DNA
bacteriophage
Bacteriophage viruses are nonliving. They are DNA or RNA encapsulated in a protein coated capsule with recognition sites to bind to specific target sites on bacteria and insert their genetic material for viral replication or to induce changes in the bacterial genetic material.
Bacteriophages ARE viruses that attack bacteria, making this question invalid. But if they meant to say "what bacteria does it attack?" then I would say T4 and E. Coli
A bacteriophage
the head
This type of virus is a bacteriophage. It attacks bacteria. The T4 bacteriophage attacks E. coli.

Bacteriophage T4 virus
Woo-Kul Lee has written: 'Kinetic modeling of the adsorption of structural stability mutants of bacteriophage T4 lysozyme at solid-water interfaces' -- subject(s): Bacteriophage T4, Absorption and adsorption, Lysozyme
Digestion of host DNA.
Once the viral DNA is duplicated in the cell.

T-Bacteriophages
Bacteriophage is the name given to a virus that infects bacteria. The name is frequently abbreviated to 'phage'. T4 phage is subject to a wide variety of experiments because it infects E. coli, and E. coli is one of the safer, more abundant and best understood bacteria to study.
T In T4 Stands For Teenager and 4 is because it is owned by Channel 4.
