Detection of molecular markers of antiviral resistance in influenza A (H5N1) viruses using a pyrosequencing method.

abstract：:The K70E mutation in human immunodeficiency virus type 1 (HIV-1) reverse transcriptase (RT) has become more prevalent in clinical samples, particularly in isolates derived from patients for whom triple-nucleoside regimens that include tenofovir (TNV), abacavir, and lamivudine (3TC) failed. To elucidate the molecular m...
