Article Synopsis
- The study monitored the circulation of Influenza A virus (AIV) in wild ducks and birds in Lombardy from 2022-2024, analyzing samples collected from hunting and dead birds using real-time RT-PCR and whole genome sequencing.
- Out of 3,497 hunted ducks, 184 tested positive for AIV, revealing 21 different subtypes, with H5N1 HPAIV being the most common during winter 2022-2023.
- In surveys of dead wild birds, notably buzzards and gulls, two buzzards and one grey heron tested positive for H5N1, while gulls showed a significant increase in positivity from 0% in 2022 to 51%
In this study, virological surveillance focused on coronaviruses in marmots in the Alpine region in 2022, captured as part of a population control reduction program in the Livigno area. Seventy-six faecal samples were randomly collected from marmots at the time of capture and release and tested for genome detection of pan-coronavirus, pan-pestivirus, canine distemper virus, and influenza A and D virus. Nine faecal samples were positive in the Pan-CoV RT-PCR, while all were negative for the other viruses.

ISKV circulation among synanthropic and sedentary species of bat, such as Savi's pipistrelle bat (Hypsugo savii) in northern Italy, may have public health implications in this region.

- The genus Lagovirus, part of the Caliciviridae family, includes both lethal viruses like rabbit hemorrhagic disease virus (RHDV) and European brown hare syndrome virus (EBHSV) and non-lethal ones such as rabbit calicivirus (RCV) and hare calicivirus (HaCV).
- Lagoviruses have two main genetic lineages: GI in rabbits (including RHDV and RCV) and GII in hares (including EBHSV and HaCV), with significant genetic recombination occurring at specific genomic junctions.
- A new strain known as RHDV type 2 (RHDV2) emerged in 2010 due to

- Porcine Respirovirus 1 (PRV1) is a negative-sense RNA virus linked to respiratory issues in pigs, first discovered in China in 2013 and later found in America and Europe.
- A study conducted in Northern Italy between September 2022 and September 2023 tested 902 pig samples, identifying PRV1 in 14 cases (1.55%), raising concerns about its role in Porcine Respiratory Disease Complex (PRDC).
- The research also detected other viruses like swine influenza virus (SIV) and porcine reproductive and respiratory syndrome virus (PRRSV) in many PRV1-positive samples, suggesting PRV1 could act as a co-factor in respiratory diseases in pigs
