Hepatitis B

25
Q

A
26
Q

What are the interactions of viruses inside cells?

A
27
Q

What is complementation?

A
28
Q

What is antigenic drift?

A

Antigenic drift- evolution due to small changes in the genome sequence within a define strain which usually occurs at a slower rate compared to antigenic shift e.g. influenza virus, rhinovirus

29
Q

What is antigenic shift?

A

Antigenic shift- usually occurs in segmented viruses, notably influenza virus, resulting in exchange (reassortment) of RNA segments between two different influenza viruses that subsequently gives rise to a highly pathogenic (reassorted) strain virus

30
Q

What is phenotypic mixing?

A
31
Q

What are the families of RNA viruses?

A
