Sep 1, 2023 · The HPAI H5N1 virus is classified as a subtype of the influenza A virus, which belongs to the family Orthomyxoviridae. HPAI H5N1 virus genome consists of a negative single-stranded RNA molecule, spanning approximately 13.5 kilobases in length.
Influenza A Virus (H5N1) - an overview | ScienceDirect Topics
Feb 15, 2019 · Subtype H5N1, causing highly pathogenic avian influenza, was identified in humans in 1997 in Hong Kong. 1 Studies on the evolutionary dynamics of influenza A H5N1 indicate that the prototype virus (A/goose/Guangdong/1/96) was derived from a low pathogenic H5 subtype carried by migratory waterfowl, and introduced into poultry in 1996.
Highly pathogenic avian influenza A (H5N1) virus outbreak in Peru …
Jun 1, 2024 · Phylogenetic tree of H5N1 subtype influenza virus hemagglutinin (A) and neuraminidase (B) genes collected during the 2022–2023 outbreak in Peru. Data were downloaded from GISAID up to September 4, 2023. The final figure was obtained with Figtree. Samples sequenced by the INS in Peru are highlighted in bold and colored red.

Jul 1, 2011 · Influenza virus A, subtype H5N1 infects birds and has been thought to have limited zoonotic potential and public health significance. In 1997, with the emergence and spread of the new Asian lineage H5N1 virus, this assumption has changed dramatically, as this virus is able to infect a broad spectrum of non-avian species, including humans ...
Influenza A Virus (H1N2) - an overview | ScienceDirect Topics
Oct 31, 2005 · Influenza viruses are enveloped, −ssRNA viruses found within the Orthomyxoviridae family. Three genera exist with this family that pertain to influenza viruses, Influenzavirus A, Influenzavirus B, and Influenzavirus C, each of which contain a single species, or type: Influenza A virus, Influenza B virus, and Influenza C virus, respectively (Table 10.1).
Self-service multimodal detection of subtype influenza A virus …
Mar 1, 2024 · The sensor was capable of differentiating the target H5N1 virus from other IAV subtypes with high specificity and sensitivity (LOD = 11.6 fM), and the detection of the virus could be enabled by fluorescence spectroscopy, UV–vis spectrophotometry, and colorimetric indication three modes, to provide a reliable point-of-care detection method for ...

Oct 1, 2024 · In nondairy matrices, acidic and caustic conditions do promote H5N1 and other influenza virus decay at varying rates (Shahid et al., 2009; Wanaratana et al., 2010). Research is needed to determine what specific pH, hold times, and temperatures are required to reduce H5N1 loads to below detectable levels of infectious virus before disposal of ...
H5N1 avian influenza virus PB2 antagonizes duck IFN-β signaling …
Jan 3, 2024 · H5N1 AIV PB2 is a negative regulator of duMAVS-mediated type I IFN pathway A previous study demonstrated that the PB2 protein of H1N1 subtype influenza virus inhibited the production of type I interferon in A549 cells (Graef et al. 2010).
Detection of H5, H7 and H9 subtypes of avian influenza viruses by ...
Jan 1, 2009 · Subtype-specific multiplex reverse transcription-polymerase chain reaction (RT-PCR) was developed to simultaneously detect three subtypes (H5, H7 and H9) of avian influenza virus (AIV) type A. The sensitivity of the multiplex RT-PCR was evaluated and compared to that of RT-PCR–enzyme-linked immunosorbent assay (ELISA) and conventional RT-PCR.
The inactivation of avian influenza virus subtype H5N1 isolated …
Jan 6, 2010 · In early 2004, the outbreaks of avian influenza virus subtype H5N1 were reported in several Asian countries including South Korea, Vietnam, Japan, Taiwan, Laos, Cambodia, China, Pakistan, Indonesia and Thailand (OIE, 2004). In Thailand, the AIV subtype H5N1 epidemics caused severe losses to the poultry industry (OIE, 2004).
