The ability of a pathogen to affect cells
I don't know! Why are you asking me?????
A virion is an entire virus particle. It is the complete form of a virus with an outer protein shell, an inner core of DNA or RNA, and a capsid.
Smallpox is a virulent disease.
Virulent means actively poisonous. You could use it in a sentence as, "the man had a virulent snake bite."
The answer in the textbook I have (Modern Bio. Holt) says radiation or certain chemicals can cause a prophage to become virulent. (pg. 494)
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.
Virulent.
Virulent
Yes, chickenpox virus is virulent. 90% of household contacts to chickenpox will become ill if they weren't already immune.

A virus which invades a cell can be said to be virulent. One that causes the host cell to immediately produce virus' particles and lose it's ability to live is said to be a lytic virus. A virus that remains "silent" for awhile is called a lysogenic virus.
It won't hurt; the flu vaccine is non-virulent and won't lower your immune system while it makes antibodies to the influenza virus. It will still be able to fight off the Bell's Palsy virus (herpes).
phages of virulent.
No. To prove this, Dr Fenner inoculated himself with myxomatosis virus which was highly virulent for rabbits. Not a single sign of disease.
A virion is an entire virus particle. It is the complete form of a virus with an outer protein shell, an inner core of DNA or RNA, and a capsid.
The Norwalk virus (Norovirus) does not have a lyosgenic cycle. It does not remain dormant as lysogenic viruses can. It is lytic and is considered virulent as many lytic viruses are. Most bacteriophages are lysogenic. See link below:
Pestilence is presence of an infectious epidemic that is very virulent, devastating, and usually fatal. Although it is spreading quickly and is now at pandemic proportions, so far Swine Flu (A-H1N1/09 Virus) is a mild influenza with low mortality rates. Since viruses mutate quickly, there is still the risk that will happen and the virus will change into a more virulent form.
