Host-range barrier of influenza A viruses.
نویسندگان
چکیده
Ample evidence suggests that all influenza viruses in mammals were probably derived from those in wild waterfowl at some time. In addition to those already established in mammals, the viruses have been transmitted to both mammals and to poultry from wild waterfowl and caused outbreaks in recent years. Experimentally, however, the viruses from one species of animals do not grow efficiently in other species. For example, human influenza viruses do not replicate in ducks or in horses, indicating their host range restriction. This paper reviews current knowledge on the host-range restriction of influenza viruses, focusing on the role of the hemagglutinin (HA).

BACKGROUND: The H9N2 subtype of avian influenzaviruses (AIVs) has been isolated in multiple avian species inmany European, Asian, African and American countries. Sincethe first outbreak of H9N2 virus in Iran in 1998, this virus haswidely circulated throughout the country, resulting in majoreconomic losses in chicken flocks. Several amino acids in thevirus ribonucleoprotein (RNP) complex includi...
متن کاملHost Range Restriction and Pathogenicity in the Context of Influenza Pandemic
Influenza A viruses cause pandemics at random intervals. Pandemics are caused by viruses that contain a hemagglutinin (HA) surface glycoprotein to which human populations are immunologically naive. Such an HA can be introduced into the human population through reassortment between human and avian virus strains or through the direct transfer of an avian influenza virus to humans. The factors tha...

The spread of influenza viruses in multiple bird and mammalian species is a worldwide serious threat to human and animal populations' health and raise major concern for ongoing pandemic in humans. Direct transmission of the avian viruses which have sialic acid specific receptors similar to human influenza viruses are a warning to the emergence of a new mutant strain that is likely to share mole...
متن کاملPhylogenetic analysis of PB2 gene of H9N2 subtype of avian influenza viruses isolated from commercial chickens in Tehran province of Iran during 1998-2001
The PB2 protein of influenza A viruses has been shown as host range determinant. In this study PB2gene of five H9N2 isolates from Tehran province during the period of 1998-2001 were partially amplifiedand sequenced to do phylogenetic study. Iranian isolates could be classified in Eurasian lineage according totheir PB2 gene sequences. The PB2 genes of these isolates are different from those of M...
