Infection dynamics of subtype H9N2 low pathogenic avian influenza a virus in turkeys

Virology
While mammals can be infected by influenza A virus either sporadically or with well adapted lineages, aquatic birds are the natural reservoir of the pathogen. So far most of the knowledge on influenza virus dynamics was however gained on mammalian models. In this study, we infected turkeys using a low pathogenic avian influenza virus and determined the

Replication and Pathology of Duck Influenza Virus Subtype H9N2 in Chukar.

Biomedical and environmental sciences : BES, 2018
To investigate the susceptibility of Chukars to duck avian influenza virus H9N2 and explore their role in interspecies transmission of influenza viruses. Chukars were inoculated with duck avian influenza viruses H9N2. The present study demonstrated that inflammatory lesions and virus antigen were present in the trachea, bronchus, and parabronchus, and ...

Hemagglutinin affects replication, stability and airborne transmission of the H9N2 subtype avian influenza virus

Virology
H9N2 subtype avian influenza virus (AIV) can transmit by direct as well as airborne contacts. It has been widespread in poultry and continued to contribute to zoonotic spillover events by providing its six internal genes for the reassortment of novel influenza viruses (eg, H7N9) that infect poultry and humans.

Comparison of different inoculation methods of H9N2 subtype avian influenza virus in broiler chickens

Comparative Clinical Pathology, 2011
H9N2 of avian influenza (AI) subtype has been reported from commercial poultry farms in many countries. This virus has been circulating in poultry industry of different parts of Iran for the last decade. To study the infection of avian influenza H9N2 in chicken of Kerman, one of the characterized H9N2 subtype of Iranian isolate was inoculated by ...

[Avian influenza virus subtype H9N2 replicates in human lung tissues].

Bing du xue bao = Chinese journal of virology, 2013
Avian influenza virus subtype H9N2 has been circulating in multiple terrestrial birds and repeatedly infecting mammals, including swines and humans to pose a significant threat to public health. The cross-species infection of human, replication activity and tissue tropism of avian influenza virus H9N2 was evaluated in this study.

Co-infection of H9N2 subtype avian influenza virus and infectious bronchitis virus decreases SP-A expression level in chickens

Veterinary Microbiology, 2017
Chicken surfactant protein A (cSP-A) is a collectin believed to play an important role in antiviral immunity. However, cSP-A expression in the respiratory tract of chickens after viral co-infection remains unclear. The aim of this study was the detection and characterization of cSP-A in co-infected chickens.

Optimizing the process of inactivating influenza virus subtype H9N2 by formalin in the production of killed avian influenza vaccine

2017
Avian influenza is one of the most important diseases in avian industry, which also threats human population. Thus, vaccination is necessary for controlling this viral disease. In this study, killed vaccine of avian influenza subtype H9N2 and formalin solution (for virus inactivation) were used.

Sero-conversion of Avian Influenza Virus Subtype H9N2 in Non-Vaccinated Commercial Poultry Flocks

Journal of Antivirals & Antiretrovirals, 2016
Sero-conversion of pathogenic subtypes (H5, H7 and H9) of Avian Influenza Virus types was studied in commercial poultry farms in the Province of Punjab, Pakistan during the years 2015-16. Out of 6731 morbid tissues, only 11 samples (4 from broiler, 4 from broiler breeder and 3 from commercial layers farms) were found positive for Avian Influenza Virus (
