This study analyzes genetic diversity and evolution of European swine influenza A viruses from 2013 to 2022, identifying 150 genotypes and highlighting pig trade as a driver of viral spread.

This study uses controlled transmission experiments to estimate how vaccination affects susceptibility and infectiousness in geese infected with H5N1, finding that vaccination reduces transmission but not below one under intensive exposure.

This paper develops a multi-species luciferase-based double antigen ELISA for detecting H5 clade 2.3.4.4b-specific antibodies in various species, showing high sensitivity and specificity.

The paper tracks the evolution of Avian Influenza H5N1 genotype EA-2024-DI across three epidemic waves, showing changes in transmission patterns and increased mammalian host adaptation.

This paper tracks the outbreak of HPAIV H5N1 euBB in black-headed gulls and common terns in Germany, showing multiple incursions, high mortality, and population declines.

The paper identifies H5N1 avian influenza virus as the cause of a mass mortality event in Eurasian cranes in Germany in 2025, linked to their social behavior.

This study inoculates pigs with porcine respirovirus type 1 (PRV1) and shows it causes chronic tracheitis and mild pneumonia in the upper respiratory tract, while swine orthopneumovirus (SOV) did not establish infection.

A unique HPAIV H5N3 genotype caused mass mortality in red knots in 2020, suggesting red knots may act as a reservoir for the virus.

The paper investigates the impact of HPAIV H5N1 on avian raptors during epizootics in Germany, finding they act as both indicators of the virus and victims, with mixed outcomes for their population stability.
