Bovine ephemeral fever virus (BEFV) is a member of the genus Ephemerovirus in the family Rhabdoviridae. It is an arthropod-borne virus transmitted by many species of midges and mosquitoes. It can cause severe economic consequences due to losses in milk production and the general condition of cattle and water buffalo.

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.

We isolated Issyk-Kul virus (ISKV) from a bat sampled from Italy in 2021 and conducted ISKV-specific surveillance in bats collected in Italy during 2017-2023. 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.

Article Synopsis
  • Canine distemper virus (CDV) is a highly contagious and often fatal disease affecting both wild and domestic carnivores, with significant recent outbreaks in Italy, particularly impacting fox populations in the Emilia-Romagna region.
  • In a study, 67 foxes and one badger were examined, revealing that 16% tested positive for CDV, indicating a concerning presence of the virus following rising mortality rates in local wildlife.
  • Two distinct CDV lineages were identified, one linked to previous outbreaks in northern Italy, and a mutation associated with increased virulence was found across all positive samples, suggesting a potentially more dangerous form of the virus.

Foot-and-mouth disease (FMD) is a viral disease, widespread and highly contagious, that mainly affects cloven-hoofed domestic and wild animals. FMD can lead to high economic losses due to the reduction in animal production such as a drop in milk production, loss of body weight, and a high mortality rate in young ruminants. Sixteen samples were collected from animals showing typical clinical signs of FMD during the last FMD outbreak in Libya in 2018-2019.

Aujeszky's disease is caused by , and its main reservoir host is the pig. However, other species are also susceptible. Infection with this virus causes a severe neurological clinical picture named Aujeszky's disease, usually accompanied by itching and death a few days after the onset of symptoms.
