    Sammanfattning : Influenza A viruses cause seasonal and pandemic outbreaks that range from mild infections to the disastrous Spanish Flu. Resistance to neuraminidase inhibitors (NAIs) is a growing problem as these drugs constitute a vital part of treatment strategies and pandemic preparedness plans worldwide. Oseltamivir (Tamiflu®) is the mostly used NAI. LÄS MER

  3. 2. Tamiflu in the Water : Resistance Dynamics of Influenza A Virus in Mallards Exposed to Oseltamivir

    Sammanfattning : The natural reservoir of influenza A virus (IAV) is wild waterfowl, and all human IAVs have their genetic origins from avian viruses. Neuraminidase inhibitors (NAIs) are currently the best drugs for treatment of human influenza; therefore, the orally available NAI oseltamivir (Tamiflu®) has been stockpiled worldwide as part of pandemic preparedness planning.

    Sammanfattning : Shikimic acid production using recombinant E.coli has been developed during the past 15 years due to the increased demand of this product, primarily as a starting material for the anti-influensa medicine Tamiflu?. A detailed metabolic analysis of a shikimic acid producing E. LÄS MER

    Sammanfattning : Influenza A virus belongs to the Orothomyxoviridae family of viruses and is one of the most common pathogens that cause infections of the respiratory tract. The aim of this thesis was to investigate if neuraminidase inhibitor (NAI) Tamiflu® (oseltamivir, OC) and Relenza® (zanamivir, ZA) - related resistance mutations exist in the neuraminidase (NA) gene of viruses collected from wild birds.
