Vertical Transmission of H9N2 Avian Influenza Virus in Goose [PDF]

Frontiers in Microbiology, 2017
During a study on high mortality cases of goose embryo in Shandong Province, China (2014–2015), we isolated an H9N2 avian influenza virus (AIV) strain (A/goose/Shandong/DP01/2014, DP01), which was supposedly the causative agent for goose embryo death ...

Epidemiological and Phylogenetic Analysis of Reassorted H10Nx Avian Influenza Viruses in Guangdong Province, China. [PDF]

Influenza Other Respir Viruses
ABSTRACT Aims H10 subtype avian influenza viruses circulate widely among wild and domestic birds worldwide. These viruses have crossed species barriers to infect mammals, including humans, with cases of H10N3, H10N5 and H10N8 reported. During active surveillance in Guangdong Province, China, between 2023 and 2025, we isolated 10 H10Nx influenza A ...

LPAIV H9N2 drives the differential expression of goose interferons and proinflammatory cytokines in both in vitro and in vivo studies

Frontiers in Microbiology, 2016
Geese, as aquatic birds, are an important natural reservoir of avian influenza virus (AIV). To characterize the innate antiviral immune response against AIV H9N2 strain infection in geese as well as the probable relationship between the expression of ...

Effect of Baicalin on Bacterial Secondary Infection and Inflammation Caused by H9N2 AIV Infection in Chickens. [PDF]

Biomed Res Int, 2020
H9N2 subtype avian influenza virus (H9N2 AIV) is a low pathogenic virus that is widely prevalent all over the world. H9N2 AIV causes immunosuppression in the host and often leads to high rates of mortality due to secondary infection with Escherichia.
