Influenza A virus
|Species||Influenza A virus|
Influenza viruses that cause influenza in vertebrates, including birds, humans, and other mammals.
Influenza A virus genome is comprised of 8 negative-sense RNA segments, encoding 10 proteins (hemagglutinin (HA), neuraminidase (N), membrane channel protein, nucleoprotein, matrix protein, polymerase basic 1, polymerase basic 2, polymerase acidic protein, nonstructural protein 1 and nonstructural protein 2). The HA protein is categorized into 18 subtypes and confers the H number in the influenza strain (e.g. H1, H3, etc). Similarly, the N protein has 11 sub-types and confers the N number in the influenza strain (e.g. N1, N2, etc.). During co-infection of two strains, reassortment can occur to produce new strains of influenza.
