1-Intro to Viruses Flashcards
What are the attributes of the Herpes virus?
Enveloped, Icosahedral, dsDNA
What are the attributes of the Paramyxoviruses?
Enveloped, Helical, -ssRNA
What are the attributes of the Corona virus?
Enveloped, Helical, +ssRNA
What are the attributes of the Picorna virus?

What kind of virus cell interactions is Steady State?
Productive/Non-cytocidal
The virus kills the cell as part of its infection and produces virus - productive/cytocidal
Lytic/cytocidal
The virus kills the cell but not as part of its normal replication - it just makes the cell so sick it cannot live - productive/cytocidal
Cytopathic/cytocidal
What kind of virus cell interactions is Latent?
Non-productive/non-cytocidal
Doesn’t produce any virus but can reactivate
The infected cell can fuse membranes of neighboring cells to form a large multinucleate cell.
Syncytial Forming
Makes cells more likely to cause cancer.
Cell Transforming
