In vivo inhibition of NAS preparation on H9N2 subtype AIV

Virologica Sinica, 2010
NAS preparation, a kind of Chinese herbal medicine found by the Yunnan Eco-agricultural Research Institute, has potential antiviral activity. In this paper, the inhibiting effect of NAS preparation on H9N2 subtype Avian influenza virus (AIV) was investigated in vivo. Chickens infected with H9N2 virus were treated with NAS preparation for 4 days.

Isolation and characterization of low pathogenic H9N2 avian influenza A viruses from a healthy flock and its comparison to other H9N2 isolates

, 2013
Several outbreaks of avian influenza (AI) caused by H9N2 subtype, have been reported in the poultry industry during 1990 around the globe. Currently, H9N2 are endemic in the large area of Middle and Far East, including Pakistan. Since H9N2 AI viruses are

Intranasal Mosaic H1N1 Live Attenuated Influenza Vaccine Elicits Broad Cross‐Reactive Immunity and Protection Against Group 1 and 2 Influenza A Viruses

MedComm, Volume 6, Issue 12, December 2025.
Our study introduces the mosaic H1N1 LAIV, an intranasal broad‐spectrum influenza vaccine that integrates the mosaic antigen design with LAIV technology. Intranasal boosting in mice elicits robust mucosal, humoral, and cellular immunity, as well as provides extensive protection against both homologous and heterologous influenza strains.

Vaccine Efficacy on the Novel Reassortant H9N2 Virus in Indonesia

, 2020
Vaccination is one of the leading methods of controlling the spread of the Avian Influenza (AI) viruses in Indonesia. The variety of circulating viruses and their ability to mutate must be followed by updating the vaccine master seed used in the field ...

Avian Influenza (H9N2) Outbreak In Iraq

The Iraqi Journal of Veterinary Medicine, 2008
An outbreak of avian influenza (AI) (H9N2) occurred in broiler, layers andbreeder chicken farms in Iraq during 2004-2007. Mortality between 30% and70% in broilers and 5% and 10% in layers and breeders were commonlyobserved on the affected farms. Mixed infections of the influenza virus withother respiratory pathogens particularly Newcastle Disease (ND ...

Identification of a novel strain of influenza A (H9N2) virus in chicken

Virologica Sinica, 2015
We identified a novel strain of influezna A H9N2 virus infection in chicken in China. Genomic and phylogenetic investigation revealed that the internal genes of the novel H9N2 virus strain were closely related to the emerging human H10N8 virus. These results suggest that the chicken H9N2 virus may be the internal gene source of the novel human H10N8 ...

Image_6_Reported human infections of H9N2 avian influenza virus in China in 2021.JPEG

, 2023
IntroductionThe continued emergence of human infections of H9N2 avian influenza virus (AIV) poses a serious threat to public health. The prevalent Y280/G9 lineage of H9N2 AIV in Chinese poultry can directly bind to human receptors, increasing the risk of

H9N2 avian influenza virus in Korea: evolution and vaccination

Clinical and Experimental Vaccine Research, 2013
Low pathogenic avian influenza (LPAI) H9N2 viruses have been circulating in the Eurasian poultry industry resulting in great economic losses due to declined egg production and moderate to high mortality. In Korea, H9N2 LPAI was first documented in 1996 and it caused serious economic loss in the Korean poultry industry, including layer and broiler ...

PB2 mutations arising during H9N2 influenza evolution in the Middle East confer enhanced replication and growth in mammals.

PLoS Pathogens, 2019
Avian influenza virus H9N2 has been endemic in birds in the Middle East, in particular in Egypt with multiple cases of human infections since 1998. Despite concerns about the pandemic threat posed by H9N2, little is known about the biological properties ...
