What disease does T4 bacteriophage cause?
E. coli infection
The T4 Phage initiates an E. coli infection by recognizing cell surface receptors of the host with its long tail fibers (LTF).
How does a T4 bacteriophage infect a bacterium?
Infection process. The T4 virus initiates an Escherichia coli infection by binding OmpC porin proteins and lipopolysaccharide (LPS) on the surface of E. coli cells with its long tail fibers (LTF). A recognition signal is sent through the LTFs to the baseplate.
What is M13 in biology?
M13 is a filamentous bacteriophage which infects E. coli host. The M13 genome has the following characteristics: Circular single-stranded DNA.
What are the two types of phages?
There are two primary types of bacteriophages: lytic bacteriophages and temperate bacteriophages. Bacteriophages that replicate through the lytic life cycle are called lytic bacteriophages, and are so named because they lyse the host bacterium as a normal part of their life cycle.
Why is T4 bacteriophage important?
T4 is a member of the Myoviridae family of bacteriophages. These phages have a sheath around the tail tube that contracts during infection (Fig. 1) (8). T4 has a complex baseplate that is essential for assuring a highly efficient infection mechanism (8).
How does the T4 virus work?
The virus bacteriophage T4 infects the bacterium Escherichia coli using an intriguing nanoscale injection machinery that employs a contractile tail. The injection machinery is responsible for recognizing and puncturing the bacterial host and transferring the viral genome into the host during infection.
Why is M13 used for sequencing?
M13 is the vector of choice for dideoxy sequencing for two main reasons. First, M13 bacteriophages are packaged in single strands of DNA, which are extruded from infected Escherichia coli cells into the surrounding culture medium.
What diseases are caused by bacteriophages?
These include diphtheria, botulism, Staphylococcus aureus infections (i.e. skin and pulmonary infections, food poisoning, and toxic shock syndrome), Streptococcus infections, Pasteurella infections, cholera, Shiga toxing-producing Shigella and Escherichia coli infections, and Pseudomonas aeruginosa infections.
What is the difference between bacteria and bacteriophage?
A bacterium is a single cell that can divide to form two cells. Virus: ↑ A type of microbe that can infects cells. Human viruses infect human cells, plant viruses infect plant cells, etc. Bacteriophage: ↑ A virus that infects bacteria, also called a phage.
Why is it called lambda phage?
Enterobacteria phage λ (lambda phage, coliphage λ, officially Escherichia virus Lambda) is a bacterial virus, or bacteriophage, that infects the bacterial species Escherichia coli (E. coli). It was discovered by Esther Lederberg in 1950….Lambda phage.

What is M13 based vector?
M13 cloning vectors have been developed for the selection of DNA sequences capable of directing initiation of DNA synthesis on single-stranded templates. These vectors are derived from viable M13 mutants containing large deletions in the region of the complementary strand origin.
