Virology Flashcards
1
Q
Tropism
A
Requiring a specific host to replicate in (e.g., animals, plants, bacteria)
2
Q
Antigenic shift
A
Major change within the genetic structure of a virus.
3
Q
Antigenic drift
A
Minor changes in the genetic structure that occur during replication and thus can occur all the time.
4
Q
Is antigenic shift or drift responsible for seasonal flu vaccines being necessary?
A
Drift
5
Q
Virion
A
A virion is a virus particle (measured in nm)
Obligate intracellular pathogens. Cannot self-replicate.
Non-living but infectious
