Isolation of influenza A H1N2 viruses from an outbreak in Yokohama City during the 2001-2002 influenza season in Japan.

Isolation of H9N2 Subtype of Avian Influenza Viruses during an Outbreak in Chickens in Iran

Avian influenza is an important disease of poultry with the potential to cause major epidemics resulting in significant economic losses. The presence of avian influenza viruses (AIV) in chickens in Iran has not been previously reported. An avian influenza outbreak in broiler, layer and breeder farms occurred during a very hot summer in July 1998. Three AIV isolates designated as 101, 102 and 10...

Seasonal Outbreak of Influenza A virus Infection in Pediatric Age Groups During 2004-2005 in South of Iran

Background: The pandemic and regional influenza outbreaks resulting from antigenic variation of influenza viruses have been the subject of numerous studies which are crucial to the preparation of the vaccine. Frequent global winter outbreaks of influenza viruses require a constant surveillance of emerging influenza variants in order to develop efficient influenza vaccine. Methods: This study wa...

Isolation of oseltamivir-resistant influenza A/H1N1 virus of different origins in Yokohama City, Japan, during the 2007-2008 influenza season.

Neuraminidase 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...

Influenza AH1N2 Viruses, United Kingdom, 2001–02 Influenza Season

During the winter of 2001-02, influenza AH1N2 viruses were detected for the first time in humans in the U.K. The H1N2 viruses co-circulated with H3N2 viruses and a very small number of H1N1 viruses and were isolated in the community and hospitalized patients, predominantly from children <15 years of age. Characterization of H1N2 viruses indicated that they were antigenically and genetically hom...
