The T4 phage is named "T4" as part of a classification system for bacteriophages developed by researchers. The "T" stands for "type," and the number "4" indicates that it was the fourth type identified in a series of similar phages. T4 specifically infects Escherichia coli (E. coli) bacteria and is well-studied for its complex structure and life cycle. Its designation reflects its historical context in the study of viruses that infect bacteria.
No, there is currently no vaccine for the Enterobacteria Phage T4 virus. This virus infects bacteria, not humans, so it is not a target for vaccine development.
T4's "full name" is "Enterobacteria phage T4"!

The Enterobacteria phage T4 virus was discovered by the American microbiologist Max Delbrück and his colleagues in the early 1940s. Delbrück, along with Salvador Luria and Alfred D. Hershey, conducted experiments that contributed to the understanding of bacteriophages, specifically T4, as model systems for studying genetics and molecular biology. Their work laid the foundation for subsequent research in virology and genetics.
c. Repression of the phage genome - A phage coded protein, called a repressor, is made which binds to a particular site on the phage DNA, called the operator, and shuts off transcription of most phage genes EXCEPT the repressor gene. The result is a stable repressed phage genome which is integrated into the host chromosome. Each temperate phage will only repress its own DNA and not that from other phage, so that repression is very specific (immunity to superinfection with the same phage).Reference: http://pathmicro.med.sc.edu/mayer/phage.htm
T4 bacteriophage is a common virus that infects E. coli bacteria. It injects its genetic material into the bacterium, taking over the host's machinery to replicate itself. This ultimately leads to the destruction of the bacterial cell and the release of new phages.
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.
When a phage attaches to a bacterium, it injects its genetic material (DNA or RNA) into the cell. The phage capsid (outer protein coat) typically stays attached to the cell surface during this process.
The function of bacteria is to reproduce. Bacteria is a large domain of prokaryotic microorganisms. They are also the cause of human and animal diseases. Some bacteria, like those in the intestines are friendly and needed for digestion.
The US equivalent to a T4 is called a W-2.
T4 bacteriophage primarily infects bacteria, specifically Escherichia coli (E. coli), which is a common model organism in microbiology. It attaches to and injects its genetic material into the bacterial cell, leading to the reproduction of new phage particles and ultimately the lysis of the bacterial cell. While T4 is specific to bacteria, it plays a crucial role in studying bacteriophage biology and has implications for bacterial genetics and biotechnology.
