The Genome Organization of the Nidovirales: Similarities and Differences between Arteri-, Toro-, and Coronaviruses

Seminars in Virology, 1997
Viruses in the families Arteriviridae and Coronaviridae have enveloped virions which contain nonsegmented, positive-stranded RNA, but the constituent genera differ markedly in genetic complexity and virion structure. Nevertheless, there are striking resemblances among the viruses in the organization and expression of their genomes, and sequence ...

Whole-Genomic Characterization of Two Different PRRSV-1 Strains Isolated From a Single Pig. [PDF]

Transbound Emerg Dis
Recent studies have demonstrated that porcine reproductive and respiratory syndrome virus 1 (PRRSV‐1) strains isolated from different farms in China have significant genomic heterogeneity, whereas strains from the same farm present a high degree of genomic similarity.

[Etiology of epidemic outbreaks COVID-19 on Wuhan, Hubei province, Chinese People Republic associated with 2019-nCoV (Nidovirales, Coronaviridae, Coronavirinae, Betacoronavirus, Subgenus Sarbecovirus): lessons of SARS-CoV outbreak.]

Voprosy virusologii, 2020
Results of analysis of phylogenetic, virological, epidemiological, ecological, clinical data of COVID-19 outbreaks in Wuhan, China (PRC) in comparison with SARS-2002 and MERS-2012 outbreaks allow to conclude: - the etiological agent of COVID-19 is coronavirus (2019-CoV), phylogenetically close to the SARS-CoV, isolated from human, and SARS-related ...

Late Reactivation of SARS-CoV-2: A Case Report

Frontiers in Medicine, 2020
SARS-CoV-2 is a betacoronavirus that belongs to the family Coronaviridae and the order Nidovirales (1). During December 2019, a series of pneumonia cases caused by a SARS-CoV-2 outbreak was identified in Wuhan, Hubei, China, and rapidly spread across the

In-depth Bioinformatic Analyses of Human SARS-CoV-2, SARS-CoV, MERS-CoV, and OtherNidoviralesSuggest Important Roles of Noncanonical Nucleic Acid Structures in Their Lifecycles [PDF]

, 2020
AbstractNoncanonical nucleic acid structures play important roles in the regulation of molecular processes. Considering the importance of the ongoing coronavirus crisis, we decided to evaluate genomes of all coronaviruses sequenced to date (stated more broadly, the orderNidovirales) to determine if they contain noncanonical nucleic acid structures.

Enveloped, Positive-Strand RNA Viruses (Nidovirales)

, 2008
Nidoviruses form a phylogenetically compact but diverse group of enveloped positive-stranded RNA viruses with the largest RNA genome known. They infect a broad range of hosts, including humans, other mammals, birds, fish, and shrimp. Nidovirus infection starts by binding to a receptor on the cell surface, and fusion of the viral and cellular membranes ...

Analysis of synonymous codon usage in SARS Coronavirus and other viruses in the Nidovirales

Virus Research, 2004
In this study, we calculated the codon usage bias in severe acute respiratory syndrome Coronavirus (SARSCoV) and performed a comparative analysis of synonymous codon usage patterns in SARSCoV and 10 other evolutionary related viruses in the Nidovirales.

Development and Characterization of a cDNA-Launch Recombinant Simian Hemorrhagic Fever Virus Expressing Enhanced Green Fluorescent Protein: ORF 2b’ Is Not Required for In Vitro Virus Replication

Viruses, 2021
Simian hemorrhagic fever virus (SHFV) causes acute, lethal disease in macaques. We developed a single-plasmid cDNA-launch infectious clone of SHFV (rSHFV) and modified the clone to rescue an enhanced green fluorescent protein-expressing rSHFV-eGFP that ...
