High pathogenicity avian influenza A (H5N1) clade 2.3.4.4b virus infection in a captive Tibetan black bear (Ursus thibetanus): investigations based on paraffin-embedded tissues, France, 2022

The paper characterizes H5N1 virus infection in a Tibetan black bear using histopathology and sequencing of paraffin-embedded tissues, finding high genetic similarity to a gull strain and evidence of mammalian adaptation.

The Feather Epithelium Contributes to the Dissemination and Ecology of clade 2.3.4.4b H5 High Pathogenicity Avian Influenza Virus in Ducks

This study shows that the feather epithelium in ducks supports viral replication and releases infectious virions, contributing to environmental spread of H5 HPAIVs.

A real-time colorimetric reverse transcription loop-mediated isothermal amplification (RT-LAMP) assay for the rapid detection of highly pathogenic H5 clade 2.3.4.4b avian influenza viruses

This paper develops a real-time colorimetric RT-LAMP assay for rapid detection of H5 clade 2.3.4.4b avian influenza viruses with 86.11% sensitivity in 30 minutes.

Two major epidemics of highly pathogenic avian influenza virus H5N8 and H5N1 in domestic poultry in France, 2020-2022

This study analyzes two HPAI epidemics in French poultry, showing most outbreaks occurred in newly designated High-Risk Zones, which were effective in predicting outbreak locations.

Phylodynamic assessment of control measures for highly pathogenic avian influenza epidemics in France

This study uses phylodynamic analysis to assess the impact of control measures on H5N8 avian influenza spread in France, finding that culling reduced inter-departmental spread but transport within departments increased local transmission.

Detection of a novel enterotropic Mycoplasma gallisepticum-like in European Starling (Sturnus vulgaris) around poultry farms in France

The paper detects a novel Mycoplasma gallisepticum-like strain in European starlings near poultry farms, suggesting potential gene transfer between synanthropic birds but not poultry infection.

Host factors drive the within-host competition between highly and low pathogenic H5N8 avian influenza viruses

The paper investigates how host factors influence the competition between low and high pathogenic H5N8 avian influenza viruses, showing differential outcomes in chickens and ducks.

Inferring within-flock transmission dynamics of highly pathogenic avian influenza (H5N8) in France, 2020

This study uses a stochastic epidemic model and ABC-SMC to estimate H5N8 transmission dynamics in ducks, revealing key parameters and latent threats in France in 2020.
