Avian influenza is a disease caused by influenza A virus (IAV) that mainly affects domestic poultry but poses a serious zoonotic threat due to direct transmission from poultry to mammals including human beings. While the high pathogenic avian influenza (HPAI) mainly caused by H5 and H7 subtypes of IAVs lead to high mortality, the low pathogenic avian ...

Avian Influenza Virus RNA Extraction
2014The efficient extraction and purification of viral RNA is critical for downstream molecular applications such as the sensitive and specific detection of virus in clinical samples, virus gene cloning and expression, gene sequencing, or quantification of avian influenza (AI) virus by molecular methods from experimentally infected birds.

Avian Influenza Virus and DIVA Strategies
Viral Immunology, 2016Vaccination is becoming a more acceptable option in the effort to eradicate avian influenza viruses (AIV) from commercial poultry, especially in countries where AIV is endemic. The main concern surrounding this option has been the inability of the conventional serological tests to differentiate antibodies produced due to vaccination from antibodies ...

Although influenza A viruses of avian origin have long been responsible for influenza pandemics, including the "Spanish flu" pandemic of 1918, human infections caused by avian subtypes of influenza A virus, most notably H5N1, have emerged since the 1990s (H5N1 in 1997; H9N2 in 1999; and H7N7 in 2003).

Avian influenza virus: Of virus and bird ecology
Vaccine, 2009The recent introductions of highly pathogenic avian influenza (HPAI) H5N1 virus in wild birds and its subsequent spread throughout Asia, the Middle East, Africa and Europe has put a focus on the role of wild birds in the geographical spread of HPAI H5N1 virus.

Update on Avian Influenza Virus
2023Avian influenza virus (AIV) epidemics continue to cause mortality in wild bird populations, including zoo birds, with concern about the welfare of all affected birds, population effects in highly protected species, and the economy of poultry production.

Novel avian influenza virus vaccines
Revue Scientifique et Technique de l'OIE, 2009Current vaccines against avian influenza (AI) virus infections are primarily based on classical inactivated whole-virus preparations. Although administration of these vaccines can protect poultry from clinical disease, sterile immunity is not achieved under field conditions, allowing for undetected virus spread and evolution under immune cover ...

Nihon rinsho. Japanese journal of clinical medicine, 2006
Influenza viruses are classified as A, B, or C based on the antigenicity of their nucleoproteins and matrix proteins. Influenza A viruses are further categorized into subtypes based on the antigenicity of two of their surface proteins, the hemagglutinin and neuraminidase. All avian influenza viruses are type A viruses.

Influenza Virus A H5N1 (“Avian Influenza”)
2010A nasal pharyngeal aspirate (NPA) is the specimen of choice for exclusion of influenza H5 strains in young children while a nasopharyngeal swab may be easier to obtain for older children and adults. Swabs should be collected and transported in the primary collection container containing viral transport medium (VTM).

Avian Influenza Virus Transmission to Mammals
2014Influenza A viruses cause yearly epidemics and occasional pandemics. In addition, zoonotic influenza A viruses sporadically infect humans and may cause severe respiratory disease and fatalities. Fortunately, most of these viruses do not have the ability to be efficiently spread among humans via aerosols or respiratory droplets (airborne transmission ...
