We isolated and characterized three H5 HPAIVs with different NA subtypes (N1, N6 and N8) during avian influenza virus (AIV) surveillance in wild birds during 2015-2016. The P126/H5N1, P560/H5N6 and ST/H5N8 viruses were highly pathogenic to chickens and ducks. Furthermore, P126/H5N1 and P560/H5N6 showed high pathogenicity in mice. Continued circulation of these influenza virus strains clearly poses a significant potential health threat to poultry and human populations.

In 2016-2017, several subtypes of the highly pathogenic avian influenza (HPAI) virus were isolated on the territory of Russia. In the autumn of 2016, during the avian influenza virus surveillance in t...
H5Nx clade 126.96.36.199 highly pathogenic avian influenza viruses (HPAIVs) have been disseminated to wide geographic regions since 2014. In 2016, five distinct genotypes (C-1 to C-5) of clade 188.8.131.52c H5N6...
The low pathogenic avian influenza A(H7N9) viruses (LPAI) were first identified in 2013 and have continued to infect humans since then. It was reported in February 2017 that the LPAI H7N9 virus has ev...
Novel highly pathogenic avian influenza (HPAI) H7N9 viruses of the fifth epidemic wave infect humans and poultry. Recently, HPAI H7N9 viruses have evolved into different subtypes and genotypes, exhibi...
Rapid and accurate diagnosis of influenza virus infection is essential for quick responses for both human and animal health. The Alere™ i Influenza A&B is a novel isothermal nucleic acid amplificati...
The highly pathogenic avian influenza (HPAI) H5N1 virus arrived in the Middle East in 2005 and has since established itself in local domestic birds and is now considered endemic in several...
Influenza, also known as the flu, is a contagious respiratory illness caused by influenza viruses. The illness can range in severity, from mild to severe to even death, and it causes an es...
The purpose of this research study is to study the safety and effectiveness of vaccinating individuals who have previously received an avian influenza vaccine derived from one type of H5N1...
The study will be an open-label phase 2 clinical trial of a single dose of an inactivated H7N9 vaccine (non-adjuvanted). The subjects of the study will be individuals who previously partic...
The main focus of the study is : - To estimate seroprevalence of AI in poultry-exposed and non-exposed human populations. - To estimate the incidence of AI in poultry-exposed and n...
A subtype of INFLUENZA A VIRUS that is highly virulent in poultry and wild birds, but shows varying degrees of pathogenicity in mice. The H5N8 virus subtype has a polybasic amino acid motif at the HA cleavage site which explains its pathogenicity in birds, and expresses surface proteins HEMAGGLUTININ 5 and NEURAMINIDASE 8 which are typical of Highly Pathogenic Avian Influenza viruses.
Infection of domestic and wild fowl and other BIRDS with INFLUENZA A VIRUS. Avian influenza usually does not sicken birds, but can be highly pathogenic and fatal in domestic POULTRY.
A subtype of INFLUENZA A VIRUS comprised of the surface proteins hemagglutinin 7 and neuraminidase 1. This subtype has demonstrated the ability to mutate from a low pathogenic form to a highly pathogenic form in birds. It was responsible for a 1999 outbreak in turkeys in Italy.
Membrane glycoproteins from influenza viruses which are involved in hemagglutination, virus attachment, and envelope fusion. Fourteen distinct subtypes of HA glycoproteins and nine of NA glycoproteins have been identified from INFLUENZA A VIRUS; no subtypes have been identified for Influenza B or Influenza C viruses.
A subtype of INFLUENZA A VIRUS comprised of the surface proteins hemagglutinin 5 and neuraminidase 2. The H5N2 subtype has been found to be highly pathogenic in chickens.
Influenza or 'flu' is a respiratory illness associated with infection by influenza virus. Symptoms frequently include headache, fever, cough, sore throat, aching muscles and joints. There is a wide spectrum of severity of illness ranging from min...
Swine Flu - H1N1 influenza - H7N9
Swine flu is the common name given to a relatively new strain of influenza (flu) that caused a flu pandemic in 2009-2010. It is also referred to as H1N1 influenza (because it is the H1N1 strain of virus). The H1N1 flu virus will be one of the main vi...
