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?
Naked, Icosahedral, +ssRNA
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

HBV, and HCV
Which type of virus, naked or enveloped, can be transferred through the fecal oral route?
Naked
What is the neutralizing antibody for Naked viruses?
capsid proteins
What is the neutralizing antibody for Enveloped viruses?
envelope glycoproteins embedded in the lipid bilayer
