The paper identifies a second genetically distinct Shamonda virus clade in European cattle, indicating independent introductions and highlighting implications for diagnostics and control.

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.

A novel 'Shamonda-like' orthobunyavirus was identified in dairy cattle in Central Europe in 2026, following exclusion of other pathogens.

This study shows that pigs recovering from a moderately virulent ASFV infection retain protective immunity for at least six months, as evidenced by reduced clinical signs and viral load upon challenge with a highly virulent strain.

The paper conducts serological surveillance of H5 HPAI in wildlife in North-East Germany, finding seropositivity in boar and carnivores but not ruminants, indicating avian-to-mammalian spillover.

We experimentally infected laboratory-reared Culicoides sonorensis biting midges with bluetongue virus (BTV) serotypes 3 and 8 using virus-containing blood meal and found slightly higher replication rates of BTV-3.

This study investigates the role of non-structural proteins NSs and NSm in Schmallenberg virus infection of Culicoides sonorensis midges, finding that their absence does not affect infection rates, but a fetal-derived variant fails to replicate in midges.

The study tested rats in Berlin for coronaviruses and found SARS-CoV-2 antibodies in one rat but no evidence of circulation, while detecting rodent-associated alphacoronaviruses.

Bluetongue virus serotype 3 was detected in Culicoides biting midges in Germany in October 2023, coinciding with its emergence in ruminants and the presence of Schmallenberg virus in midge pools.
