  2. 6. Prescription – Pollution – Poo – Pandemics - Priorities : Neuraminidase Inhibitors from an Environmental Resistance Development Perspective

    Author : Marie Nykvist; Josef D. Järhult; Mikael Leijon; Uppsala universitet; []
    Keywords : Influenza A virus; neuraminidase inhibitor; resistance; environmental; Mallard; zanamivir; avian influenza;

    Abstract : The natural Influenza A virus (IAV) host is waterfowl. Human IAV is treated with neuraminidase inhibitors (NAIs), which are stockpiled worldwide in case of an IAV pandemic. As the drugs escape regular waste water treatment, they can be detected in river waters. READ MORE

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

    Author : Anna Gillman; Josef D Järhult; Björn Olsen; Shaman Muradrasoli; Elena Govorkova; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Influenza A virus; avian influenza; oseltamivir; neuraminidase inhibitors; resistance; environmental; Mallard; waterfowl; Medical Science; Medicinsk vetenskap;

    Abstract : 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.

  5. 8. Tamiflu® - Use It and Lose It?

    Author : Josef D. Järhult; Björn Olsen; Hanna Söderström; Jonas Waldenström; Robert G. Webster; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; influenza; oseltamivir; Tamiflu; resistance development; H274Y; environment; pharmaceuticals; mallard; dabbling duck; avian influenza; influensa; resistensutveckling; miljö; läkemedel; gräsand; Infektionssjukdomar; Infectious Diseases;

    Abstract : 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. READ MORE

  6. 9. Large-scale releases of native species: the mallard as a predictive model system

    Author : Pär Söderquist; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Human alteration of natural systems, and its consequences are of great concern and the impact on global ecosystems is one of the biggest threats that biodiversity stands before. Translocations of invasive species, as well as intraspecific contingents with non-native genotypes, whether they are deliberate or unintentional, are one such alteration and its consequences are continuously being assessed.

  7. 10. Eco-immunological studies of innate immunity in Mallards (Anas platyrhynchos)

    Author : Anu S. Helin; Jonas Waldenström; Edwin Veldhuizen; Linnéuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Avian β-defensins AvBDs ; Avian gene expression; Host-pathogen interactions; Innate immunity; Mallard Anas platyrhynchos ; Myxovirus resistance gene Mx ; Retinoic acid inducible gene 1 RIG-I ; Avian β-defensins AvBD ; Genuttryck; Gräsand Anas platyrhynchos ; Immunförsvar; Immungener; Myxovirus resistant gene Mx ; Patogen; Retinoic acid inducible gene 1 RIG-I ; Ecology; Ekologi;

    Abstract : This thesis comprises two sections, both of which explore eco-immunology of the innate immune system of mallards (Anas platyrhynchos). The innate immune system serves a pivotal role as the first line of defense against invading pathogens, and is comprised of physical and chemical barriers. READ MORE
