Predicting Hosts Based on Early SARS-Cov-2 Samples And
www.nature.com/scientificreports OPEN Predicting hosts based on early SARS‑CoV‑2 samples and analyzing the 2020 pandemic Qian Guo1,2,3,7, Mo Li4,7, Chunhui Wang4,7, Jinyuan Guo1,3,7, Xiaoqing Jiang1,2,5,7, Jie Tan1, Shufang Wu1,2, Peihong Wang1, Tingting Xiao6, Man Zhou1,2, Zhencheng Fang1,2, Yonghong Xiao6* & Huaiqiu Zhu1,2,3,5* The SARS‑CoV‑2 pandemic has raised concerns in the identifcation of the hosts of the virus since the early stages of the outbreak. To address this problem, we proposed a deep learning method, DeepHoF, based on extracting viral genomic features automatically, to predict the host likelihood scores on fve host types, including plant, germ, invertebrate, non‑human vertebrate and human, for novel viruses. DeepHoF made up for the lack of an accurate tool, reaching a satisfactory AUC of 0.975 in the fve‑ classifcation, and could make a reliable prediction for the novel viruses without close neighbors in phylogeny. Additionally, to fll the gap in the efcient inference of host species for SARS‑CoV‑2 using existing tools, we conducted a deep analysis on the host likelihood profle calculated by DeepHoF. Using the isolates sequenced in the earliest stage of the COVID‑19 pandemic, we inferred that minks, bats, dogs and cats were potential hosts of SARS‑CoV‑2, while minks might be one of the most noteworthy hosts. Several genes of SARS‑CoV‑2 demonstrated their signifcance in determining the host range. Furthermore, a large‑scale genome analysis, based on DeepHoF’s computation for the later pandemic in 2020, disclosed the uniformity of host range among SARS‑CoV‑2 samples and the strong association of SARS‑CoV‑2 between humans and minks. -
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. -

Hydroxychloroquine or Chloroquine for treating Coronavirus Disease 2019 (COVID-19) – a PROTOCOL for a systematic review of Individual Participant Data Authors Fontes LE, Riera R, Miranda E, Oke J, Heneghan CJ, Aronson JK, Pacheco RL, Martimbianco ALC, Nunan D BACKGROUND In the face of the pandemic of SARS CoV2, urgent research is needed to test potential therapeutic agents against the disease. Reliable research shall inform clinical decision makers. Currently, there are several studies testing the efficacy and safety profiles of different pharmacological interventions. Among these drugs, we can cite antimalarial, antivirals, biological drugs, interferon, etc. As of 6 April 2020 there are three published reportsand 100 ongoing trials testing hydroxychloroquine/chloroquine alone or in association with other drugs for COVID-19. This prospective systematic review with Individual Participant data aims to assess the rigour of the best-available evidence for hydroxychloroquine or chloroquine as treatment for COVID-19 infection. The PICO framework is: P: adults with COVID-19 infection I: chloroquine or hydroxychloroquine (alone or in association) C: placebo, other active treatments, usual standard care without antimalarials O: efficacy and safety outcomes OBJECTIVES To assess the effects (benefits and harms) of chloroquine or hydroxychloroquine for the treatment of COVID-19 infection. METHODS Criteria for considering studies for this review Types of studies We shall include randomized controlled trials (RCTs) with a parallel design. We intend to include even small trials (<50 participants), facing the urgent need for evidence to respond to the current pandemic. Quasi-randomized, non-randomized, or observational studies will be excluded due to a higher risk of confounding and selection bias (1). -

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. -

Discovery of Bat Coronaviruses Through Surveillance and Probe Capture-Based Next-Generation Sequencing
RESEARCH ARTICLE Clinical Science and Epidemiology Discovery of Bat Coronaviruses through Surveillance and Probe Capture-Based Next-Generation Sequencing Bei Li,a Hao-Rui Si,a,b Yan Zhu,a Xing-Lou Yang,a Danielle E. Anderson,c Zheng-Li Shi,a Lin-Fa Wang,c Peng Zhoua aCAS Key Laboratory of Special Pathogens, Wuhan Institute of Virology, Center for Biosafety Mega-Science, Chinese Academy of Sciences, Wuhan, China bUniversity of Chinese Academy of Sciences, Beijing, China cProgramme in Emerging Infectious Diseases, Duke-NUS Medical School, Singapore, Singapore Bei Li and Hao-Rui Si contributed equally. Author order was determined by the importance of their work. ABSTRACT Coronaviruses (CoVs) of bat origin have caused two pandemics in this century. Severe acute respiratory syndrome (SARS)-CoV and Middle East respiratory syndrome (MERS)-CoV both originated from bats, and it is highly likely that bat coronaviruses will cause future outbreaks. Active surveillance is both urgent and essential to predict and mitigate the emergence of these viruses in humans. Next-generation sequencing (NGS) is currently the preferred methodology for vi- rus discovery to ensure unbiased sequencing of bat CoVs, considering their high genetic diversity. However, unbiased NGS is an expensive methodology and is prone to missing low-abundance CoV sequences due to the high background level of nonviral sequences present in surveillance field samples. Here, we employ a capture-based NGS approach using baits targeting most of the CoV species. Using this technology, we effectively reduced sequencing costs by increasing the sensitiv- ity of detection. We discovered nine full genomes of bat CoVs in this study and re- vealed great genetic diversity for eight of them. -
Characterization of Codon Usage Pattern in SARS- Cov-2
Characterization of Codon Usage Pattern in SARS- CoV-2 Wei Hou ( [email protected] ) Short report Keywords: COVID-19, coronaviruses, SARS-CoV-2, codon usage pattern Posted Date: August 6th, 2020 DOI: https://doi.org/10.21203/rs.3.rs-21553/v2 License: This work is licensed under a Creative Commons Attribution 4.0 International License. Read Full License Version of Record: A version of this preprint was published on September 14th, 2020. See the published version at https://doi.org/10.1186/s12985-020-01395-x. Page 1/17 Abstract The outbreak of coronavirus disease 2019 (COVID-19) due to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has posed signicant threats to international health. The genetic traits as well as evolutionary processes in this novel coronavirus are not fully characterized, and their roles in viral pathogenesis are yet largely unknown. To get a better picture of the codon architecture of this newly emerging coronavirus, in this study we perform bioinformatic analysis, based on publicly available nucleotide sequences of SARS-CoV-2 along with those of other members of human coronaviruses as well as non-human coronaviruses in different hosts, to take a snapshot of the genome-wide codon usage pattern of SARS-CoV-2 and uncover that all over-represented codons end with A/U and this newly emerging coronavirus has a relatively low codon usage bias, which is shaped by both mutation pressure and natural selection. Additionally, there is slight variation in the codon usage pattern among the SARS- CoV-2 isolates from different geo-locations. -

Comparative Transcriptome Profiling of Human and Pig Intestinal Epithelial Cells After
Comparative transcriptome profiling of human and pig intestinal epithelial cells after Deltacoronavirus infection Thesis Presented in Partial Fulfillment of the Requirements for the Degree Master of Science in the Graduate School of The Ohio State University By Diana Cruz Pulido, MSc Graduate Program in Comparative and Veterinary Medicine. The Ohio State University 2020 Thesis Committee: Scott P. Kenney, PhD, Advisor Vanessa Hale, DVM, PhD Anastasia Vlasova, DVM, PhD Copyrighted by Diana Cruz Pulido 2020 Abstract Porcine deltacoronavirus (PDCoV) is an emerging global infectious disease of the swine industry with unknown potential to cause human disease. Phylogenetic analysis suggests that PDCoV originated relatively recently from a host-switching event between birds and mammals. Little is known about how PDCoV interacts with its differing hosts. Although human derived cell lines are susceptible to PDCoV infection, there is no direct evidence that PDCoV causes morbidity in humans. Currently, there are no treatments or vaccines available for PDCoV partially due to the mechanisms of infection remaining unknown. In this study, we explored the gene expression profiles of the primary host organism (swine) to a potential novel host (humans) after infection with PDCoV. For this we utilized cell lines derived from intestinal lineages to reproduce the primary sites of viral infection in the host. Porcine intestinal epithelial cells (IPEC-J2) and human intestinal epithelial cells (HIEC) were infected with PDCoV. At 24 h post infection, total cellular RNA was harvested and analyzed using RNA-sequencing (RNA-seq) technology. We found that there are more differentially expressed genes (DEGs) in humans, 7,486, in comparison to pigs, 1134. -

Journal of General Virology Discovery of a novel nidovirus in cattle with respiratory disease --Manuscript Draft-- Manuscript Number: VIR-D-14-00290R1 Full Title: Discovery of a novel nidovirus in cattle with respiratory disease Short Title: Genetic characterization of a novel nidovirus in cattle Article Type: Short Communication Section/Category: Animal - Positive-strand RNA Viruses Corresponding Author: Rafal Tokarz Columbia University New York, NY UNITED STATES First Author: Rafal Tokarz Order of Authors: Rafal Tokarz Stephen Sameroff Richard A. Hesse Ben M. Hause Aaloki Desai Komal Jain W. Ian Lipkin Abstract: The family Coronaviridae represents a diverse group of vertebrate RNA viruses, all with genomes greater than 26,000 nucleotides. Here, we report the discovery and genetic characterization of a novel virus present in cattle with respiratory disease. Phylogenetic characterization of this virus revealed that it clusters within Torovirinae, a subfamily of Coronaviridae. The complete genome consists of only 20,261 nucleotides, and represents the smallest reported Coronaviridae genome. We identified seven open reading frames, including the canonical nidovirus open reading frames 1a and b. Analysis of polyprotein 1ab revealed that this virus, tentatively named bovine nidovirus (BoNV), shares the highest homology with the recently described python-borne nidoviruses and contains several conserved nidovirus motifs, but does not encode the NendoU or O-MT domains that are present in other viruses within Coronaviridae. In concert with its reduced genome, the atypical domain architecture indicates that this virus represents a unique lineage within the order Nidovirales.
