Fine quantification of avian influenza H5N1 escape mutant quasispecies populations using mutation-specific real-time PCR.

Abstract excerpt

Influenza viruses have a rapid replication cycle, using enzymes without proofreading capacity and generating multiple virus quasispecies during replication. The identification and quantification of these quasispecies populations require time-consuming and expensive cloning and sequencing approaches. In the present study, we developed mutation-specific real-time PCR (RT-PCR) tests for the fine quantification of...
