Influenza A virus causes influenza in birds and some mammals, and is the only species of influenza virus A genus of the Orthomyxoviridae family of viruses. Strains of all subtypes of influenza A virus have been isolated from wild birds, although disease is uncommon. Influenza virus type A was the first to be isolated in 1933, by intranasal inoculation of the ferret.Being widely used this method is an important and reliable means of control of the etiological structure of the acute respiratory diseases in different periods according to the epidemic situation.

Characteristic of many RNA genome viruses, influenza virus undergoes high mutation rates and frequent genetic reassortment (combination and rearrangement of genetic material) leading to variability in HA and NA antigens. Minor changes in the protein structure in influenza A strains ("antigenic drift" The structure of the influenza viruss HA surface proteins is designed to fit the sialic acid receptors of the human cell, like a key to a lock.How do I view different file formats (PDF, DOC, PPT, MPEG) on this site?

However, the structural basis of the mechanism underlying fusion inhibition by Arbidol has remained obscure, thereby hindering its further development as a specific and optimized influenza therapeutic.

Structure. There are three main strains of the influenza virus, types A, B and C. Type A and B viruses are the most common causes of influenza disease symptoms and epidemic outbreaks, whilst type C has a milder disease phenotype and predominantly affects children.Structural Components. Pathogenesis and Immunity. Influenza virus is transmitted from person to person primarily in droplets released by sneezing and coughing.Pure viral pneumonia of this type is a severe illness with a high mortality. Virus titers in secretions are high, and viral shedding is prolonged. This genus has one species, influenza B virus. Influenza B almost exclusively infects humans and is less common than influenza A. The only other animals known to be susceptible to influenza B infection are the seal and the ferret.Structure of the virus. Influenza virus structure.

PowerPoint Templates.INTRODUCTION Influenza , commonly referred to as the flu , is an infectious disease caused by RNA viruses of the family Orthomyxoviridae (the influenza viruses), that affects birds and mammals. Cau The cause of influenza is the influenza virus. Influenza A, B and C viruses a Influen The flu virus is an RNA virus The genome codes for five viral proteins and is made Flu virus g Haemagglutinin - this glycoprotein plays a part in infection and provides the H in the strain type. The structure of the influenza virus (see Figure 1) is somewhat variable, but the virion particles are usually spherical or ovoid in shape and 80 to 120 nanometers in diameter.

The influenza virus is the main culprit of respiratory infection more commonly known as the "flu". The structure of the influenza virus includes a nucleoprotein (RNA) center enclosed in capsid, a lipid envelope, and spikes of two key proteins on its surface: hemagglutinin and neuraminidase.

The influenza A form of the virus is the deadliest and is believed to be the source of the 1918, 1957 and 1968 flu epidemics.(The Influenza (Flu) Viruses 2004) The two proteins found on the surface of the virus are neuraminidase (NA) and hemagglutinin (HA). Influenza Viruses Although viral diseases such as AIDS and yellow fever have major economic and social impacts, they do not cause the panic caused by Influenza.Hemagglutinin and Neuraminidase have complex protein structures. They are antigens that stimulate an immune response, especially Influenza Type B Influenza B viruses are normally found only in humans. Unlike influenza A viruses, these viruses are not classified according to subtype.Strains Influenza B viruses and subtypes of influenza A virus are further characterized into strains.

Influenza A virus subtype H5 N1, also known as A(H5N1) or simply H5N1, is a subtype of the Influenza A virus which can cause illness in humans and many other animal species. Structure of Influenza virus. Influenza virion are usually spherical (diameter 80-110 nm). An enveloped virus, the outer layer is a lipid membrane which is taken from the host cell.

The virus spreads easily from person to person, mainly when an infected person coughs or sneezes. Whats more, this virus is one of the most changeable of viruses.
