Drivers for a pandemic due to avian influenza and options for One Health mitigation measures

EFSA Journal, Volume 22, Issue 4, April 2024.
Abstract Avian influenza viruses (AIV) remain prevalent among wild bird populations in the European Union and European Economic Area (EU/EEA), leading to significant illness and mortality of birds. Transmission between bird and mammal species has been observed, particularly in fur animal farms, where outbreaks have been reported.

PREVALENCE OF ANTIBODIES AGAINST INFLUENZA VIRUS IN NON-VACCINATED EQUINES FROM THE BRAZILIAN PANTANAL

Revista do Instituto de Medicina Tropical de São Paulo, 2014
The prevalence of antibodies against Equine Influenza Virus (EIV) was determined in 529 equines living on ranches in the municipality of Poconé, Pantanal area of Brazil, by means of the hemagglutination inhibition test, using subtype H3N8 as antigen. The

Avian influenza overview December 2023–March 2024

EFSA Journal, Volume 22, Issue 3, March 2024.
Abstract Between 2 December 2023 and 15 March 2024, highly pathogenic avian influenza (HPAI) A(H5) outbreaks were reported in domestic (227) and wild (414) birds across 26 countries in Europe. Compared to previous years, although still widespread, the overall number of HPAI virus detections in birds was significantly lower, among other reasons ...

The use of microarrays for the identification of the origin of genes of avian influenza viruses in wild birds

Microbiology Independent Research Journal, 2017
Forty-two strains of avian influenza viruses were isolated from the wild waterfowls’ feces in the city of Moscow. These viruses, as well as reference strains and some experimental reassortants, were analyzed by microarrays.

Effect of dexamethasone on antibody response of horses to vaccination with a combined equine influenza virus and equine herpesvirus‐1 vaccine

Journal of Veterinary Internal Medicine, Volume 38, Issue 1, Page 424-430, January/February 2024.
Abstract Background Dexamethasone is routinely administered to horses but its effect on the antibody response to a commercial EIV/EHV vaccine is unclear. Hypothesis Horses receiving dexamethasone will have lower postvaccination antibody levels against EIV and EHV‐1 than vaccinated controls. Animals Fifty‐five healthy adult research horses.

Development of Live Vaccine Candidates for Canine Influenza H3N2 Using Naturally Truncated NS1 Gene

Transboundary and Emerging Diseases, Volume 2024, Issue 1, 2024.
The NS1 influenza protein of influenza A virus is a viral nonstructural protein encoded by the NS gene segment that has multiple accessory functions during viral infection. In recent years, the major role ascribed to NS1 has been its inhibition of host immune responses, especially the limitation of both interferon (IFN) production and the antiviral ...

Strain-related variation in the persistence of influenza A virus in three types of water: distilled water, filtered surface water, and intact surface water

Virology Journal, 2013
Background The persistence of influenza A (IA) virus in aquatic habitats has been demonstrated to be a determinant for virus transmission dynamics in wild duck populations.

Global spread of H3 subtype avian influenza viruses with an accelerated evolution after interspecies transmission.

Journal of Infection
The H3 subtype avian influenza virus (AIV) has been widely spread in birds and known as a natural source of mammalian influenza viruses. Based on data from public databases and our surveillance data, we analysed the ecology, evolution, and spread of H3 ...

Emerging animal viruses: real threats or simple bystanders?

Pesquisa Veterinária Brasileira, 2013
The list of animal viruses has been frequently added of new members raising permanent concerns to virologists and veterinarians. The pathogenic potential and association with disease have been clearly demonstrated for some, but not for all of these ...
