The virus that causes bird flu disease is one form of family Orthomyxoviridae, that consists of sort A that attacks poultry, pigs B and C to attack that attack mammals and humans. however within the course of mutation, sort a scourge is additionally contagious to humans.
Type A viruses are divided into subtypes based mostly on 2 kinds of proteins on their surface. This protein referred to as haemagglutinin (HA) and Neuroaminidase (NA). Virus sort A contains a HA (Hemaglutinin) as several as sixteen pairs, specifically H1-H16 and nine NA (Neuraminidase), specifically N1-N9 who will amendment shapes. sort a scourge is most virulent H5N1 strain that proved to be transmitted from birds to humans, lions, tigers and cats.

The variation of the combined form of H and N antigens on the virus sort A manufacture the kind of virus: H5N1, H7N2, H1N7, H7N3, H13N6, H5N9, H11N6, H3N8, H9N2, H5N2, H4N8, H10N7, H2N2, H8N4, H14N5, H6N5, H12N5 and others . Some diseases are influenza in animals: Swine Flu or flu in pigs caused by virus H1N1, H1N2, H3N1 and H3N2, Avian Horses that had appeared in 1956 caused by H7N7 and H3N8 viruses.
All sort A viruses within the world and become a virulent disease at now is typically a results of mutation of the H1N1 strain, where the virus is eventually appointed because the mother of {all sorts|all kinds|every kind|every type|all sorts} of virus type A. H1N1 virus doesn't solely unfold from poultry to poultry, however it proved to vary and is unfold from human to human. it's feared that this phenomenon are going to be posed by the H5N1 virus.
Symptoms of AI (Avian Influenza) and ND (Newcastle Disease) in poultry alone is typically tough u / is distinguished mainly Velogenik ND (ND Malignant). Previously, poultry infected with AI virus may be observed from the entire body purplish blue, red spots on the proventriculus, and inflammation of the intestine. Currently ciri2 has been lost and also the most interchangeable observed solely in intestinal inflammation, significantly within the caeca tonsils and also the high mortality in poultry. It's simply that these characteristics conjointly exist within the case of ND, particularly velogenik ND (ND Malignant). This was attributable to the character of the H5N1 virus that hypermutasi, thus satu2nya how u / diagnose the laboratory tests with blood samples.
