First whole genome characterization of swine influenza virus subtype H3N2 in Thailand.
Summary of "First whole genome characterization of swine influenza virus subtype H3N2 in Thailand."
H3N2 swine influenza viruses (SIV) were first detected in Asia shortly after the 1968 pandemic emerged in humans. Subsequently, human H3N2 viruses have sporadically reappeared in swine. In Thailand, a human-like H3N2 SIV was reported in 1978 although the genetic sequence of this virus is unknown. In this study, we undertook cross sectional syndromic surveillance in pigs in four provinces in Thailand. Seven genetically similar H3N2 viruses were isolated. A representative, A/SW/Thailand/KU5.1/04, was fully sequenced and shown to contain genes from human-like influenza viruses and North American and European SIV. The results restate that transmission of influenza A virus among human and swine populations is common and that genes from both American and Eurasian SIV lineages cocirculate in Thailand.

Medical and Biotech [MESH] Definitions
Influenza A Virus, H3n2 Subtype
A subtype of INFLUENZA A VIRUS comprised of the surface proteins hemagglutinin 3 and neuraminidase 2. The H3N2 subtype was responsible for the Hong Kong flu pandemic of 1968.
Influenza A Virus, H9n2 Subtype
A subtype of INFLUENZA A VIRUS comprised of the surface proteins hemagglutinin 9 and neuraminidase 2. The H9N2 subtype usually infects domestic birds (POULTRY) but there have been some human infections reported.
Influenza A Virus, H5n2 Subtype
A subtype of INFLUENZA A VIRUS comprised of the surface proteins hemagglutinin 5 and neuraminidase 2. The H5N2 subtype has been found to be highly pathogenic in chickens.
Influenza A Virus, H1n1 Subtype
A subtype of INFLUENZA A VIRUS comprised of the surface proteins hemagglutinin 1 and neuraminidase 1. The H1N1 subtype was responsible for the Spanish flu pandemic of 1918.
Influenza A Virus, H2n2 Subtype
A subtype of INFLUENZA A VIRUS comprised of the surface proteins hemagglutinin 2 and neuraminidase 2. The H2N2 subtype was responsible for the Asian flu pandemic of 1957.
The 2009 human pandemic influenza (H1N1) virus possesses the HA gene of the H1 subtype. The evolutionary process of the 2009 H1N1 virus remains to be defined. We performed genetic analyses of the HA g...
BACKGROUND: H1N1 is the main subtype influenza A virus circulating in human and swine population, and has long been a threat to economy and public health. OBJECTIVE: To explore the genetic correlation...
The evolution of classical swine influenza viruses receptor specificity preceding the emergence of the 2009 H1N1 pandemic virus was analyzed in glycan microarrays. Classical swine influenza viruses fr...
Although swine origin A/H1N1/2009 influenza virus (hereafter "pH1N1″) has been detected in swine in 20 countries, there has been no published surveillance of the virus in African livestock. The obje...
In this study, we identify a recombinant pb1 gene, a recombinant MP segment and a recombinant PA segment. The pb1 gene is recombined from two Eurasia swine H1N1 influenza virus lineages. It belongs to...
Treatment options are limited for the new strain of the H1N1 influenza virus, which differs from the seasonal H1N1 influenza virus. This study will collect blood from people who have been...
This study is to identify the preferred vaccine dosage (of antigen and adjuvant) and schedule (one or two administrations) of the cell-derived H1N1sw monovalent vaccine in healthy children...
The outbreak of respiratory illnesses in Mexico that began in March 2009 was caused by a swine origin influenza A (H1N1) virus (S-OIV) that had not been recognized previously in pigs or hu...
This study is to identify the preferred vaccine dosage (of antigen and adjuvant) and schedule (one or two administrations) of the cell-derived H1N1sw monovalent vaccine in healthy adults b...
Influenza virus infections are a major cause of morbidity and mortality. The limited existing knowledge about the impact of influenza in immunocompromised patients suggests that they are a...
