Novel human coronavirus (SARS-CoV-2): A lesson from animal coronaviruses
Full text linkThe recent pandemic caused by the novel human coronavirus, referrred to as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), not only is having a great impact on the health care systems and economies in all continents but it is also causing radical changes of common habits and life styles. The novel coronavirus (CoV) recognises, with high probability, a zoonotic origin but the role of animals in the SARS-CoV-2 epidemiology is still largely unknown. However, CoVs have been known in animals since several decades, so that veterinary coronavirologists have a great expertise on how to face CoV infections in animals, which could represent a model for SARS-CoV-2 infection in humans. In the present paper, we provide an up-to-date review of the literature currently available on animal CoVs, focusing on the molecular mechanisms that are responsible for the emergence of novel CoV strains with different antigenic, biologic and/or pathogenetic features. A full comprehension of the mechanisms driving the evolution of animal CoVs will help better understand the emergence, spreading, and evolution of SARS-CoV-2
Erasing the Invisible Line to Empower the Pandemic Response
Full text linkA challenging debate has arisen on the role of veterinary expertise in facing the SARS-CoV-2 pandemic. It seems totally unreasonable that in most countries, veterinary diagnostic and tracing forces were not deployed at the start to perform strategic tasks, which could have mitigated the outcome of this dramatic health emergency. Erasing the invisible line between human and veterinary virology will empower the response to future pandemics

No full textCanine parvovirus vaccination and immunisation failures: Are we far from disease eradication?
Full text linkDespite extensive vaccination, canine parvovirus (CPV) remains a leading infectious cause of canine mortality, especially among juveniles. This review provides an update on CPV vaccine types and vaccination protocols. The design of CPV prevention strategies and vaccination programs with a goal of herd immunity has been hampered by deficiencies of studies that model companion animal viral infections and inform an understanding of the basic reproduction number. However, the most important issue in eradication of CPV disease is represented by immunisation failures including: i) the presence of interfering titres of maternally-derived antibodies; ii) the presence of non-responders; and iii) possible reversion to virulence. In contrast, the role of the CPV variants in immunisation failures is widely debated. Taking into account the reduced circulation of canine distemper virus and canine adenovirus type 1 in countries where extensive vaccination is carried out, more effort should be made to aim for CPV eradication, including antibody testing to determine the optimal time for vaccinations of pups and adults and homogeneous vaccine coverage of dog population

Sars‐cov‐2 pandemic: Not the first, not the last
Full text linkThe common trait among the betacoronaviruses that emerged during the past two decades (the severe acute respiratory syndrome coronavirus—SARS‐CoV, the Middle East respiratory syndrome coronavirus—MERS‐CoV, and the recent SARS coronavirus 2—SARS‐CoV‐2) is their probable animal origin, all deriving from viruses present in bat species. Bats have arisen the attention of the scientific community as reservoir of emerging viruses, given their wide geographical distribution, their biological diversity (around 1,400 species, 21 different families and over 200 genera), and their peculiar ecological and physiological characteristics which seem to facilitate them in harbouring a high viral diversity. Several human activities may enable the viral spill‐over from bats to humans, such as deforestation, land‐use changes, increased livestock grazing or intensive production of vegetal cultures. In addition, the globalization of trade and high global human mobility allow these viruses to be disseminated in few hours in many parts of the World. In order to avoid the emergence of new pandemic threats in the future we need to substantially change our global models of social and economic development, posing the conservation of biodiversity and the preservation of natural ecosystems as a pillar for the protection of global human health
Emerging hepatotropic viruses in cats: A brief review
Full text linkThe possible role of viruses in feline liver disease has long remained neglected. However, in 2018, an analogue of human hepatitis B virus was identified in cats. Moreover, antibodies for human hepatitis E have been detected consistently at various prevalence rates in cats. Although the correlation between these viruses and the liver injury in cats must be clarified, hepatotropic viruses might represent an increasing risk for feline and public health

A novel nested PCR for the diagnosis of calicivirus infections in the cat.
No full textA novel nested PCR (nPCR) assay is reported on the diagnosis of the feline calicivirus (FCV) infection. The test was performed on 47 ocular and 40 pharyngeal swabs collected from 47 cats with respiratory syndrome: among the 87 samples examined, 18 ocular and 23 pharyngeal swabs were positive in nPCR. The nPCR sensitivity was compared to other diagnostic techniques such as virus isolation on cell culture and reverse transcriptase-polymerase chain reaction (RT-PCR). The nPCR was more sensitive than the virus isolation and RT-PCR: therefore, it can be used for calicivirosis diagnosis in cats.[...
