Characterization of avian H3N3 and H1N1 influenza A viruses isolated from pigs in Canada.
نویسندگان
چکیده
H3N3 and H1N1 influenza A viruses were isolated from Canadian pigs in 2001 and 2002. These viruses are phylogenetically related to waterfowl viruses and antigenically distinct from reference swine influenza viruses. The isolation of these viruses reemphasizes the potential for interspecies transmission of influenza viruses from waterfowl to pigs in North America.

Since 1997, novel viruses of three different subtypes and five different genotypes have emerged as agents of influenza among pigs in North America. The appearance of these viruses is remarkable because there were no substantial changes in the overall epidemiology of swine influenza in the United States and Canada for over 60 years prior to this time. Viruses of the classical H1N1 lineage were v...

Material and Methods: Throat samples from Iranian pat...
متن کاملMolecular characterization of non-structural gene of H9N2 subtype of avian influenza viruses isolated from broiler chickens in Iran
BACKGROUND: The H9N2 subtype of avian influenzaviruses (AIVs) have spread in Asia and Middle East countriesand have become a serious threat to poultry industry in Iran.OBJECTIVES:Characterization of genes of H9N2 subtype involvingin pathogenicity and diagnosis are crucial in control of avianinfluenza outbreaks. The Nonstructural (NS) gene and its proteinproducts (NS1 & NS2) are important as dia...
متن کاملNeuraminidase gene sequence analysis of avian influenza H9N2 viruses isolated from Iran
Influenza A viruses possesses two virion surface glycoproteins including haemagglutinin (HA) and neuraminidase (NA). The NA plays an important role in viral replication and promotes virus release from infected cells and facilitates virus spread throughout the body. To find out any genomic changes that might be occurred on NA gene of avian influenza circulating viruses, we have genetically analy...
متن کاملAntigenic and genetic analyses of H1N1 influenza A viruses from European pigs.
H1N1 influenza A viruses isolated from pigs in Europe since 1981 were examined both antigenically and genetically and compared with H1N1 viruses from other sources. H1N1 viruses from pigs and birds could be divided into three groups: avian, classical swine and 'avian-like' swine viruses. Low or no reactivity of 'avian-like' swine viruses in HI tests with monoclonal antibodies raised against cla...
