Development of a real-time RT-PCR assay for detection of resistance to oseltamivir in influenza A pandemic (H1N1) 2009 virus using single nucleotide polymorphism probes.
Resistance to oseltamivir in pandemic (H1N1) 2009 influenza A virus is linked to an amino acid change from histidine (H) to tyrosine (Y) at position 275 in the neuraminidase protein (NA). A real-time one step RT-PCR assay using single nucleotide polymorphism (SNP) probes was developed to detect this mutation in respiratory specimens. The limit of detection was 47.6 copies/reaction for wild-type...
متن کاملDetermination of Oseltamivir Resistance Level by an H275Y Genotyping Assay among Influenza A (H1N1) Viruses in Hamadan Province, Iran
Introduction: Epidemics and deaths caused by influenza viruses are an important concern worldwide. The use of neuraminidase inhibitors such as oseltamivir is an effective and valuable way to treat the diseases caused by these viruses. However, the mutation in several parts of the gene leads to the emergence of drug-resistant strains, and an ever-increasing rise in drug-resistant strains is a gl...
متن کاملInfluenza virus susceptibility and resistance to oseltamivir.
Oseltamivir phosphate is a prodrug of oseltamivir carboxylate, a highly specific inhibitor of influenza virus neuraminidases. Given that oseltamivir carboxylate binds to highly conserved, essential amino acids in the catalytic site of the enzyme, and that the activity of neuraminidase is critical for virus release from infected cells and subsequent virus spread, the drug was expected to have a ...
متن کاملA Reverse transcription-PCR assay for detection of type A influenza virus and differentiation of avian H7 subtype
Abstract : Avian influenza virus (AIV) infection is a major cause of influenza mortality in birds and can cause human mortality and morbidity. Although the risk of infection with avian influenza virus (AIV) is generally low for most people, the pathogenic virus can cross the species barrier and acquires the ability to infect and be transmitted among the human population; therefore the ra...
متن کاملAssay to Detect Oseltamivir Resistance
To the Editor: Oseltamivir is a neuraminidase inhibitor approved for treatment and prevention of influenza virus infection. Oseltamivir resistance caused by a single amino acid substitution from histidine (H) to tyrosine (Y) at position 274 of the neuraminidase active site has been reported in persons infected both experimentally and naturally with influenza A virus subtype H5N1 (1,2). Evidence...
