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 ...

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).

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.

Reverse Genetics of the Avian Influenza Virus
2008Reverse genetics is the creation of a virus from a full-length cDNA copy of the viral genome, referred to as an infectious clone, and is the most powerful genetic tool in modern virology. The generation of influenza A viruses by reverse genetics has lagged mainly due to the inherent technical difficulties of providing a sufficient amount of all eight ...

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.

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 ...

A Brief Introduction to the Avian Influenza Virus
2008The avian influenza (AI) virus is type A influenza isolated from and adapted to an avian host. Type A influenza belongs to the orthomyxovirdae virus family, is enveloped, and is pleiomorphic with a size ranging from 80-120 nm (reviewed in [1]). Type A influenza strains are classified by the serological subtypes of the primary viral surface proteins ...

Avian Influenza A (H5N1) Virus
2014Since 1997, highly pathogenic avian influenza A (H5N1) viruses have caused unprecedented widespread poultry outbreaks with high mortality in a number of Asian, European, Middle Eastern, and African countries; have infected other animal species; and have caused sporadic, severe, and fatal human infections. Influenza viruses are single-stranded, negative-

Hemagglutination Assay for the Avian Influenza Virus
2008The hemagglutination (HA) assay is a tool used to screen cell culture or amnioallantoic fluid harvested from embryonating chicken eggs for hemagglutinating agents, such as type A influenza. The HA assay is not an identification assay, as other agents also have hemagglutinating properties.

Avian influenza virus in pregnancy.
Reviews in medical virology, 2017The unprecedented epizootic of avian influenza viruses, such as H5N1, H5N6, H7N1 and H10N8, has continued to cause disease in humans in recent years. In 2013, another novel influenza A (H7N9) virus emerged in China, and 30% of those patients died. Pregnant women are particularly susceptible to avian influenza and are more likely to develop severe ...
