Amantadine-Resistant among Seasonal H1N1 and 2009 Pandemic Isolated of Influenza A Viruses in Iran
Background and Aims: Influenza A viruses are important pathogens for humans especially in pandemic episodes. Two adamantane derivates, amantadine and rimantadine, are used for prophylaxis and treatment of influenza A virus infections. However, single amino acid substitutions in the M2 transmembrane domain which lead to amantadine resistance of these viruses occur at residues 26, 27, 30, 31 or 3...
متن کاملCharacterization of Oseltamivir-Resistant 2009 H1N1 Pandemic Influenza A Viruses
Influenza viruses resistant to antiviral drugs emerge frequently. Not surprisingly, the widespread treatment in many countries of patients infected with 2009 pandemic influenza A (H1N1) viruses with the neuraminidase (NA) inhibitors oseltamivir and zanamivir has led to the emergence of pandemic strains resistant to these drugs. Sporadic cases of pandemic influenza have been associated with muta...

متن کاملDetection of Seasonal Influenza H1N1 and H3N2 Viruses using RT-PCR Assay during 2009 Flu Pandemic in Golestan Province
Abstract Background and Objective: The emergence of a novel H1N1influenza A virus of animal origin with transmissibility from human to human poses pandemic concern. Current subtypes of Seasonal influenza A viruses spread in human are influenza A H1N1 influenza A H3N2 and influenza type B viruses. The aim of this study was to determine current strains of the H3N2 and new H1N1 subtypes of influe...
متن کاملOseltamivir-Resistant Pandemic (H1N1) 2009 Virus, Mexico
During May 2009-April 2010, we analyzed 692 samples of pandemic (H1N1) 2009 virus from patients in Mexico. We detected the H275Y substitution of the neuraminidase gene in a specimen from an infant with pandemic (H1N1) 2009 who was treated with oseltamivir. This virus was susceptible to zanamivir and resistant to adamantanes and oseltamivir.
