In spring 2022, Europe faced an unprecedented heatwave, increasing the risk of West Nile virus (WNV) outbreaks. As early as 7 June WNV was detected in Culex mosquitoes northern Italy, and - following days two blood donors, a patient with encephalitis, wild birds additional mosquito pools. Genome sequencing demonstrated co-circulation lineage 2 newly introduced 1, which discovered region 2021.
A new strain of WNV lineage 1 (WNV - 1) emerged in the Veneto Region, northern Italy, 2021, eight years after last outbreak Italy. The virus, which co-circulates with WNV-2, has become endemic where, 2022, most human cases neuroinvasive disease (WNND) reported Europe have occurred.
Since 1997, G1-lineage H9N2 avian influenza viruses have been circulating in Asia and later on the Middle East, they associated to mild respiratory disease, drops egg production moderate mortality chickens, particular presence of concurrent infections.

The increasing involvement of wild waterfowl in H5 Highly Pathogenic Avian Influenza Virus (HPAIV) circulation continues to pose a threat animal and public health worldwide. In winter 2020-2021, two field surveillance activities were carried out on weekly basis, through virological serological analyses, 823 hunted 521 trapped migratory aquatic birds northeast Italy. Sixty Eurasian teals recaptured several times, which allowed us follow the progression HPAI infection naturally infected...
Recent insights into the genetic and antigenic variability of avian metapneumovirus (aMPV), including discovery two new subtypes, have renewed interest in this virus. aMPV causes a well-known respiratory disease poultry. Domestic species show different susceptibility to whereas sporadic detections wild birds revealed links between epidemiology migration routes. To explore species, molecular survey was conducted on samples that were collected from during influenza surveillance activity Italy....
From October 2021 to January 2022, different incursions of clade 2.3.4.4b H5N1 HPAIV (Highly Pathogenic Avian Influenza Virus) occurred in several Italian regions with its main diffusion Densely Poultry Populated Areas (DPPAs) north-eastern Italy. Monitoring and control activities applied the affected area clearly evidenced that turkeys broilers were most species, although flocks at times resulted infected absence increased mortality and/or clinical signs. Thus, an approach based on sampling...
In 2021, amidst the COVID-19 pandemic and global food insecurity, Nigerian poultry sector was exposed to highly pathogenic avian influenza (HPAI) virus its economic challenges. Between 2021 2022, HPAI caused 467 outbreaks reported in 31 of 37 administrative regions Nigeria. this study, we characterized genomes 97 A viruses subtypes H5N1, H5N2, H5N8, which were identified different agro-ecological zones farms during 2021–2022 epidemic. The phylogenetic analysis HA genes showed a widespread...
The European subtype of tick-borne encephalitis virus (TBEV-Eur; species Orthoflavivirus encephalitidis, family Flaviviridae) was the only flavivirus present in central Europe known to cause neurologic disease humans and several animal species. Here, we report a isolated from Alpine chamois (Rupicapra rupicapra rupicapra) with attached ticks, over wide area Alps. Cases were detected 2017 Salzburg, Austria, 2023 Lombardy Piedmont, Italy. strains exhibit 94.8–97.3% nucleotide identities each...
A 10-month-old intact female Cane Corso dog was referred to the Veterinary Teaching Hospital of University Perugia (PG-VTH) for severe hemolytic anemia and thrombocytopenia.

Campylobacter is the most frequent foodborne zoonotic bacteria worldwide, with chicken meat being overwhelmingly important reservoir for human infections. Control measures implemented at farm level (i.e., biosecurity or vaccination), which have been successfully applied to limit other pathogens, such as Salmonella, not effective in reducing occurrence. Thus, new approaches are needed fully understand ecological interactions of host animals effectively comprehend its epidemiology. The...
Mycoplasmas are known as the minimalist microorganisms in microbes' world. Their nature makes them highly sensitive to environmental conditions and limits their ability survive for extended periods outside animal host. Nevertheless, there documented instances of mycoplasma transmission over significant distances this phenomenon may be linked relatively unexplored abilities mycoplasmas, such capacity synthesize biofilm—the predominant mode bacterial growth nature.
