Comparison of sequence analysis and a novel discriminatory real-time PCR assay for detection and quantification of Lamivudine-resistant hepatitis B virus strains

J Clin Microbiol. 2004 Aug;42(8):3809-12. doi: 10.1128/JCM.42.8.3809-3812.2004.

Abstract

We report a rapid and accurate real-time PCR-based method to quantify wild-type and lamivudine-resistant hepatitis B virus by using a common forward primer paired with different reverse primers. Excellent concordance was demonstrated between sequencing and the discriminatory real-time assay; however, a mixture of quasispecies was more frequently detected by discriminatory real-time PCR.
