Personal Statement. The overall goal of my lab over the last 40 years has been to understand the viral and host determinants of coronavirus tropism and virulence. Much of our work during the last approximately ten years has been on understanding the interactions of coronaviruses with the innate immune responses, primarily dsRNA induced anti-viral pathways. These include the canonical MAVS-dependent interferon synthesis and signaling system, the oligoadenylate synthetase-ribonuclease L (OAS-RNase L) pathway leading to limitation of virus replication and spread and the PKR pathway that leads to limitation of initiation of protein synthesis. We have extensively investigated activation the OAS-RNase L pathway and the antagonism of this pathway by coronavirus encoded phosphodiesterases. We worked with the human coronavirus severe acute syndrome coronavirus (SARS-CoV) in the past and have ongoing studies on the pathogenesis of the Middle East respiratory syndrome coronavirus (MERS-CoV). We have recently initiated investigation of the newly emerged severe acute respiratory coronavirus 2 (SARS-CoV-2) the agent of COVID-19. We need the equipment requested in this supplement application for BSL3 studies of SARS-CoV-2 1.

Contributions to Science 1. Establishment of murine coronavirus (MHV) animal model of acute encephalitis and chronic demyelinating disease. We established a mouse model of encephalitis, hepatitis and immune-mediated chronic demyelination, which we have used extensively for the mapping of viral determinants of virulence and for the study of coronavirus-host interactions. Using highly neurovirulent MHV-JHM.SD and weakly neurovirulenUhepatovirulent MHV-A59, this model formed the basis for numerous of our early studies and findings as detailed below and allowed we and others to compare infection of the CNS and the peripheral organ, the liver and to identify CNS specific aspects of virus-host interactions. We have used the A59 model, one of the few accepted animal models for Multiple Sclerosis, for studies of chronic demyelinating

  • Review a Review of Coronavirus Infection in the Central Nervous
    Review J Vet Intern Med 2001;15:438–444 A Review of Coronavirus Infection in the Central Nervous System of Cats and Mice Janet E. Foley and Christian Leutenegger Feline infectious peritonitis (FIP) is a common cause of death in cats. Management of this disease has been hampered by difficulties identifying the infection and determining the immunological status of affected cats and by high variability in the clinical, patho- logical, and immunological characteristics of affected cats. Neurological FIP, which is much more homogeneous than systemic effusive or noneffusive FIP, appears to be a good model for establishing the basic features of FIP immunopathogenesis. Very little information is available about the immunopathogenesis of neurologic FIP, and it is reasonable to use research from the well- characterized mouse hepatitis virus (MHV) immune-mediated encephalitis system, as a template for FIP investigation, and to contrast findings from the MHV model with those of FIP. It is expected that the immunopathogenic mechanisms will have important similarities. Such comparative research may lead to better understanding of FIP immunopathogenesis and rational prospects for management of this frustrating disease. Key words: Cats; Feline infectious peritonitis; Mouse hepatitis virus; Neurological disease. eline infectious peritonitis (FIP) is a fatal, immune-me- membrane), N (nucleocapsid), and S (spike glycoprotein), F diated disease produced as a result of infection of which is post-translationally modified to S1 and S2.8 The macrophages by mutant feline coronavirus strains (FIPVs).

  • On the Coronaviruses and Their Associations with the Aquatic Environment and Wastewater
    water Review On the Coronaviruses and Their Associations with the Aquatic Environment and Wastewater Adrian Wartecki 1 and Piotr Rzymski 2,* 1 Faculty of Medicine, Poznan University of Medical Sciences, 60-812 Pozna´n,Poland; [email protected] 2 Department of Environmental Medicine, Poznan University of Medical Sciences, 60-806 Pozna´n,Poland * Correspondence: [email protected] Received: 24 April 2020; Accepted: 2 June 2020; Published: 4 June 2020 Abstract: The outbreak of Coronavirus Disease 2019 (COVID-19), a severe respiratory disease caused by betacoronavirus SARS-CoV-2, in 2019 that further developed into a pandemic has received an unprecedented response from the scientific community and sparked a general research interest into the biology and ecology of Coronaviridae, a family of positive-sense single-stranded RNA viruses. Aquatic environments, lakes, rivers and ponds, are important habitats for bats and birds, which are hosts for various coronavirus species and strains and which shed viral particles in their feces. It is therefore of high interest to fully explore the role that aquatic environments may play in coronavirus spread, including cross-species transmissions. Besides the respiratory tract, coronaviruses pathogenic to humans can also infect the digestive system and be subsequently defecated. Considering this, it is pivotal to understand whether wastewater can play a role in their dissemination, particularly in areas with poor sanitation. This review provides an overview of the taxonomy, molecular biology, natural reservoirs and pathogenicity of coronaviruses; outlines their potential to survive in aquatic environments and wastewater; and demonstrates their association with aquatic biota, mainly waterfowl. It also calls for further, interdisciplinary research in the field of aquatic virology to explore the potential hotspots of coronaviruses in the aquatic environment and the routes through which they may enter it.

  • Coronaviruses Post-SARS: Update on Replication and Pathogenesis
    REVIEWS Coronaviruses post-SARS: update on replication and pathogenesis Stanley Perlman and Jason Netland Abstract | Although coronaviruses were first identified nearly 60 years ago, they only received notoriety in 2003 when one of their members was identified as the aetiological agent of severe acute respiratory syndrome. Previously these viruses were known to be important agents of respiratory and enteric infections of domestic and companion animals and to cause approximately 15% of all cases of the common cold. This Review focuses on recent advances in our understanding of the mechanisms of coronavirus replication, interactions with the host immune response and disease pathogenesis. It also highlights the recent identification of numerous novel coronaviruses and the propensity of this virus family to cross species barriers.

The complex origin, extended human-to-human transmission, pathogenesis, host immune responses, and various clinical presentations of SARS-CoV-2 have presented serious challenges in understanding and combating the pandemic situation. Human CoVs gained attention only after the SARS-CoV outbreak of 2002–2003. On the other hand, animal CoVs have been studied extensively for many decades, providing a plethora of important information on their genetic diversity, transmission, tissue tropism and pathology, host immunity, and therapeutic and prophylactic strategies, some of which have striking resemblance to those seen with SARS-CoV-2. Moreover, the evolution of human CoVs, including SARS-CoV-2, is intermingled with those of animal CoVs. In this comprehensive review, attempts have been made to compare the current knowledge on evolution, transmission, pathogenesis, immunopathology, therapeutics, and prophylaxis of SARS-CoV-2 with those of various animal CoVs.

  • Coronaviruses in Avian Species – Review with Focus on Epidemiology and Diagnosis in Wild Birds
    J Vet Res 62, 249-255, 2018 DOI:10.2478/jvetres-2018-0035 REVIEW ARTICLE Coronaviruses in avian species – review with focus on epidemiology and diagnosis in wild birds Justyna Miłek, Katarzyna Blicharz-Domańska Department of Poultry Diseases, National Veterinary Research Institute, 24-100 Puławy, Poland [email protected] Received: May 2, 2018 Accepted: September 19, 2018 Abstract Coronaviruses (CoVs) are a large group of enveloped viruses with a single-strand RNA genome, which continuously circulate in mammals and birds and pose a threat to livestock, companion animals, and humans. CoVs harboured by avian species are classified to the genera gamma- and deltacoronaviruses. Within the gamma-CoVs the main representative is avian coronavirus, a taxonomic name which includes the highly contagious infectious bronchitis viruses (IBVs) in chickens and similar viruses infecting other domestic birds such as turkeys, guinea fowls, or quails. Additionally, IBVs have been detected in healthy wild birds, demonstrating that they may act as the vector between domestic and free-living birds. Moreover, CoVs other than IBVs, are identified in wild birds, which suggests that wild birds play a key role in the epidemiology of other gammaCoVs and deltaCoVs. Development of molecular techniques has significantly improved knowledge of the prevalence of CoVs in avian species. The methods adopted in monitoring studies of CoVs in different avian species are mainly based on detection of conservative regions within the viral replicase, nucleocapsid genes, and 3’UTR or 5’UTR. The purpose of this review is to summarise recent discoveries in the areas of epidemiology and diagnosis of CoVs in avian species and to understand the role of wild birds in the virus distribution.

    Ge et al. Virology Journal (2017) 14:98 DOI 10.1186/s12985-017-0766-9 RESEARCH Open Access Detection of alpha- and betacoronaviruses in rodents from Yunnan, China Xing-Yi Ge1,4, Wei-Hong Yang2, Ji-Hua Zhou2, Bei Li1, Wei Zhang1, Zheng-Li Shi1* and Yun-Zhi Zhang2,3* Abstract Background: Rodents represent the most diverse mammals on the planet and are important reservoirs of human pathogens. Coronaviruses infect various animals, but to date, relatively few coronaviruses have been identified in rodents worldwide. The evolution and ecology of coronaviruses in rodent have not been fully investigated. Results: In this study, we collected 177 intestinal samples from thress species of rodents in Jianchuan County, Yunnan Province, China. Alphacoronavirus and betacoronavirus were detected in 23 rodent samples from three species, namely Apodemus chevrieri (21/98), Eothenomys fidelis (1/62), and Apodemus ilex (1/17). We further characterized the full-length genome of an alphacoronavirus from the A. chevrieri rat and named it as AcCoV-JC34. The AcCoV-JC34 genome was 27,649 nucleotides long and showed a structure similar to the HKU2 bat coronavirus. Comparing the normal transcription regulatory sequence (TRS), 3 variant TRS sequences upstream the spike (S), ORF3, and ORF8 genes were found in the genome of AcCoV-JC34. In the conserved replicase domains, AcCoV-JC34 was most closely related to Rattus norvegicus coronavirus LNRV but diverged from other alphacoronaviruses, indicating that AcCoV-JC34 and LNRV may represent a novel alphacoronavirus species. However, the S and nucleocapsid proteins showed low similarity to those of LRNV, with 66.5 and 77.4% identities, respectively.

Genomic information has been widely used to understand the pathogenesis, animal origin and mode of transmission of coronaviruses in the aftermath of the 2002–2003 severe acute respiratory syndrome (SARS) and 2012 Middle East respiratory syndrome (MERS) outbreaks. Furthermore, genome sequencing and bioinformatic analysis have had an unprecedented relevance in the battle against the 2019–2020 coronavirus disease 2019 (COVID-19) pandemic, the newest and most devastating outbreak caused by a coronavirus in the history of mankind. Here, we review how genomic information has been used to tackle outbreaks caused by emerging, highly pathogenic, betacoronavirus strains, emphasizing on SARS-CoV, MERS-CoV and SARS-CoV-2.

Innate Immune Antagonism By Diverse Coronavirus Phosphodiesterases Abstract Coronaviruses comprise a large family of viruses within the order Nidovirales containing single-stranded positive-sense RNA genomes of 27-32 kilobases. Divided into four genera (alpha, beta, gamma, delta) and multiple newly defined subgenera, coronaviruses include a number of important human and livestock pathogens responsible for a range of diseases. Historically, human coronaviruses OC43 and 229E have been associated with up to 30% of common colds, while the 2002 emergence of severe acute respiratory syndrome- associated coronavirus (SARS-CoV) first raised the specter of these viruses as possible pandemic agents. Although the SARS-CoV pandemic was quickly contained and the virus has not returned, the 2012 discovery of Middle East respiratory syndrome-associated coronavirus (MERS-CoV) once again elevated coronaviruses to a list of global public health threats. The eg netic diversity of these viruses has resulted in their utilization of both conserved and unique mechanisms of interaction with infected host cells. Like all viruses, coronaviruses encode multiple mechanisms for evading, suppressing, or otherwise circumventing host antiviral responses.
