|
Describe antigenic drift and shift. |
Antigenic drift Hosts become persistently infected following insertion of a provirus into the genome of host cells. With continuous production of virus particles many target cells become infected During further virus production by reverse transcription mutations frequently arise due to errors during transcription process. This can result in the emergence of new virus strains exhibiting antigenic variation in envelope glycoproteins. Antigenic shift Genome segmentation enables exchange of the segments between circulating strains. After such re-assortment strains with a new genetic pattern and properties emerge rapidly. |

Briefly describe two mechanisms of the genetic variability of the influenza virus. |
Antigenic Drift Natural mutation over time within genes encoding binding sites. Virus particles new strains that cannot be inhibited as effectively by original Ab that previously targeted strain Host immune system evasion Easier virus spread Occurs in all types of influenza Antigenic Shift A sudden shift in antigenicity of virus that result from recombination of the genome of two viral strains The new subtype has a mixture of the surface antigens of both original strains Specific Reassortment Phenotypic change E.g. two different strains of influenza infect the same cell at the same time Lipids envelope removed RNA exposed Transcription to mRNA New virus with combined Ag of parent strains only occurs in influenza A Affecting mammals and birds Also in Maedi-Visna |
