Pathology and molecular detection of influenza Asubtype H9N2 virus in commercial poultry in Nigeria, 2024

Open Veterinary Journal
Background: After the first Avian Influenza H5N1 outbreak in Nigerian poultry in 2006, subsequent waves of outbreaks occurred, causing substantial losses. Despite effective control measures by 2008, a resurgence in 2015 led to further losses and required depopulation efforts.

The Inhibitory Effect of cLF-chimera, a Recombinant Antimicrobial Peptide, on Avian Influenza Virus Subtype H9N2

, 2023
Abstract Avian influenza subtype H9N2 is the most prevalent influenza virus in poultry worldwide. It imposes economic losses on the poultry industry and has zoonotic potential. Currently, there are two main groups of anti-influenza drugs in use; Adamantanes and Neuraminidase inhibitors.

Effect of Chicken AvBD11 on the Cytokines in the Erythrocytes of Chickens Infected with the Avian Influenza Virus of the Subtype H9N2

Animals
(1) The aim of this study was to elucidate the role of the Gallus gallus avian β-defensin 11 (AvBD11) in the immune response induced by the avian influenza virus H9N2. (2) AvBD11 was expressed using E. coli, and the effects of different concentrations of AvBD11 on cytokine expression in the ex vivo and in vivo erythrocytes of chickens infected with the

Potential of Neuraminidase from Pasteurella multocida for Inhibiting Avian Influenza Virus Subtype H9N2 Replication In Ovo

, 2023
In recent decades, neuraminidase/sialidase-based antivirals have been produced to suppress respiratory viral infections, including avian influenza, which relies on sialic acid as the entry point for viruses into cells.

Effects of the Glycosylation of the HA Protein of H9N2 Subtype Avian Influenza Virus on the Pathogenicity in Mice and Antigenicity

Transboundary and Emerging Diseases
As the H9N2 subtype avian influenza virus (H9N2 AIV) evolves naturally, mutations in the hemagglutinin (HA) protein still occur, which involves some sites with glycosylations. It is widely established that glycosylation of the H9N2 AIV HA protein has a major impact on the antigenicity and pathogenicity of the virus. However, the biological implications

Recombinant influenza H9N2 virus with a substitution of H3 hemagglutinin transmembrane domain showed enhanced immunogenicity in mice and chicken

, 2017
In recent years, avian influenza virus H9N2 undergoing antigenic drift represents a threat to poultry farming as well as public health. Current vaccines are restricted to inactivated vaccine strains and their related variants.

Isolation and characterization of H6N1 and H9N2 avian influenza viruses from Ducks in Hanoi, Vietnam. [PDF]

, 2012
We report the genetic characterization of low pathogenic avian influenza (LPAI) viruses isolated from domestic ducks in northern Vietnam in 2009. In total, 22 influenza A viruses consisting of 21 H6N1 subtypes and one H9N2 subtype were isolated from 1488
