I think that polio was virulent before 1955 when the vaccine was developed. Now, I think, since we have developed a vaccine, it isn't as virulent.

What is the similarities in temperate and virulent viruses?
They both require a host cell to reproduce and they are both types of viruses
What is the difference between a temperature and virulent virus?
A virulent virus is a virus that has severe symptoms and is usually a dangerous disease. A temperate virus is a less violent sickness that may show little to no symptoms.
The development of virulent toxin producing bacterial strains due to the presence of a temperate phage can occur in?
specialized transduction
What is the difference between a virulent phage and a temperate phage?
In virology, temperate refers to the life cycle some phages are able to perform. Atemperate phage can integrate its genome into its host bacterium's chromosome, becoming a lysogen known as a prophage. A temperate phage is also able to undergo lytic life cycles, where the prophage is expressed, replicates the phage genome and produces phage progeny and the progeny phage leave the bacterium. The virulent phages have only lytic lifecycles and thus infection results in the host cell's death (due to lytic cell destruction-the phage replicates itself and then bursts the cell, releasing many copies).
What is a virulent phages?
phages of virulent.
How would use virulent be used in a sentence?

How would you use the word virulent in a sentence?
Virulent means actively poisonous. You could use it in a sentence as, "the man had a virulent snake bite."
What do you call a bacteriophage when it is in a lysogenic cycle?
Phages that replicate only via the lytic cycle are known as virulent phages while phages that replicate using both lytic and lysogenic cycles are known as temperate phages.
