Severe Acute Respiratory Syndrome
Spike Glycoprotein, Coronavirus
A class I viral fusion protein that forms the characteristic spikes, or peplomers, found on the viral surface that mediate virus attachment, fusion, and entry into the host cell. During virus maturation, it is cleaved into two subunits: S1, which binds to receptors in the host cell, and S2, which mediates membrane fusion.
Simian virus 40
Viruses which lack a complete genome so that they cannot completely replicate or cannot form a protein coat. Some are host-dependent defectives, meaning they can replicate only in cell systems which provide the particular genetic function which they lack. Others, called SATELLITE VIRUSES, are able to replicate only when their genetic defect is complemented by a helper virus.
The type species of ALPHAVIRUS normally transmitted to birds by CULEX mosquitoes in Egypt, South Africa, India, Malaya, the Philippines, and Australia. It may be associated with fever in humans. Serotypes (differing by less than 17% in nucleotide sequence) include Babanki, Kyzylagach, and Ockelbo viruses.
Influenza A Virus, H1N1 Subtype
Influenza A Virus, H5N1 Subtype
A subtype of INFLUENZA A VIRUS comprised of the surface proteins hemagglutinin 5 and neuraminidase 1. The H5N1 subtype, frequently referred to as the bird flu virus, is endemic in wild birds and very contagious among both domestic (POULTRY) and wild birds. It does not usually infect humans, but some cases have been reported.
Influenza A Virus, H3N2 Subtype
Hepatitis B virus
The type species of the genus ORTHOHEPADNAVIRUS which causes human HEPATITIS B and is also apparently a causal agent in human HEPATOCELLULAR CARCINOMA. The Dane particle is an intact hepatitis virion, named after its discoverer. Non-infectious spherical and tubular particles are also seen in the serum.
West Nile virus
A species of FLAVIVIRUS, one of the Japanese encephalitis virus group (ENCEPHALITIS VIRUSES, JAPANESE). It can infect birds and mammals. In humans, it is seen most frequently in Africa, Asia, and Europe presenting as a silent infection or undifferentiated fever (WEST NILE FEVER). The virus appeared in North America for the first time in 1999. It is transmitted mainly by CULEX spp mosquitoes which feed primarily on birds, but it can also be carried by the Asian Tiger mosquito, AEDES albopictus, which feeds mainly on mammals.
Respiratory Syncytial Viruses
The mechanism by which latent viruses, such as genetically transmitted tumor viruses (PROVIRUSES) or PROPHAGES of lysogenic bacteria, are induced to replicate and then released as infectious viruses. It may be effected by various endogenous and exogenous stimuli, including B-cell LIPOPOLYSACCHARIDES, glucocorticoid hormones, halogenated pyrimidines, IONIZING RADIATION, ultraviolet light, and superinfecting viruses.
Vesicular stomatitis Indiana virus
The ability of a pathogenic virus to lie dormant within a cell (latent infection). In eukaryotes, subsequent activation and viral replication is thought to be caused by extracellular stimulation of cellular transcription factors. Latency in bacteriophage is maintained by the expression of virally encoded repressors.
Hemagglutinin Glycoproteins, Influenza Virus
Membrane glycoproteins from influenza viruses which are involved in hemagglutination, virus attachment, and envelope fusion. Fourteen distinct subtypes of HA glycoproteins and nine of NA glycoproteins have been identified from INFLUENZA A VIRUS; no subtypes have been identified for Influenza B or Influenza C viruses.

Identification of a novel coronavirus in patients with severe acute respiratory syndrome. (1/1050)BACKGROUND: The severe acute respiratory syndrome (SARS) has recently been identified as a new clinical entity. SARS is thought to be caused by an unknown infectious agent. METHODS: Clinical specimens from patients with SARS were searched for unknown viruses with the use of cell cultures and molecular techniques. RESULTS: A novel coronavirus was identified in patients with SARS. The virus was isolated in cell culture, and a sequence 300 nucleotides in length was obtained by a polymerase-chain-reaction (PCR)-based random-amplification procedure. Genetic characterization indicated that the virus is only distantly related to known coronaviruses (identical in 50 to 60 percent of the nucleotide sequence). On the basis of the obtained sequence, conventional and real-time PCR assays for specific and sensitive detection of the novel virus were established. Virus was detected in a variety of clinical specimens from patients with SARS but not in controls. High concentrations of viral RNA of up to 100 million molecules per milliliter were found in sputum. Viral RNA was also detected at extremely low concentrations in plasma during the acute phase and in feces during the late convalescent phase. Infected patients showed seroconversion on the Vero cells in which the virus was isolated. CONCLUSIONS: The novel coronavirus might have a role in causing SARS. (+info)
A novel coronavirus associated with severe acute respiratory syndrome. (2/1050)BACKGROUND: A worldwide outbreak of severe acute respiratory syndrome (SARS) has been associated with exposures originating from a single ill health care worker from Guangdong Province, China. We conducted studies to identify the etiologic agent of this outbreak. METHODS: We received clinical specimens from patients in seven countries and tested them, using virus-isolation techniques, electron-microscopical and histologic studies, and molecular and serologic assays, in an attempt to identify a wide range of potential pathogens. RESULTS: None of the previously described respiratory pathogens were consistently identified. However, a novel coronavirus was isolated from patients who met the case definition of SARS. Cytopathological features were noted in Vero E6 cells inoculated with a throat-swab specimen. Electron-microscopical examination revealed ultrastructural features characteristic of coronaviruses. Immunohistochemical and immunofluorescence staining revealed reactivity with group I coronavirus polyclonal antibodies. Consensus coronavirus primers designed to amplify a fragment of the polymerase gene by reverse transcription-polymerase chain reaction (RT-PCR) were used to obtain a sequence that clearly identified the isolate as a unique coronavirus only distantly related to previously sequenced coronaviruses. With specific diagnostic RT-PCR primers we identified several identical nucleotide sequences in 12 patients from several locations, a finding consistent with a point-source outbreak. Indirect fluorescence antibody tests and enzyme-linked immunosorbent assays made with the new isolate have been used to demonstrate a virus-specific serologic response. This virus may never before have circulated in the U.S. population. CONCLUSIONS: A novel coronavirus is associated with this outbreak, and the evidence indicates that this virus has an etiologic role in SARS. Because of the death of Dr. Carlo Urbani, we propose that our first isolate be named the Urbani strain of SARS-associated coronavirus. (+info)
Epidemiology, clinical presentation and laboratory investigation of severe acute respiratory syndrome (SARS) in Canada, March 2003. (3/1050)As of 23 March, 2003, 11 cases of SARS have been reported in Canada. Three patients had travelled to China, including Hong Kong SAR. The remaining eight had a history of close contact with cases. There have been three deaths. To date, evidence for human metapneumovirus has been found in six cases; further studies are ongoing to determine whether this virus is the causative agent of the SARS or whether other, so far undetected, pathogens are responsible. Public health measures are being implemented at the local, provincial, and national levels to identify new cases and prevent secondary transmission of SARS. (+info)
Update: outbreak of severe acute respiratory syndrome--worldwide, 2003. (4/1050)CDC and the World Health Qrganization (WHO) are continuing to investigate the multicountry outbreak of unexplained atypical pneumonia referred to as severe acute respiratory syndrome (SARS). Pending development of confirmatory laboratory testing capacity, CDC's interim suspected SARS case definition is based on clinical criteria and epidemiologic linkage to other SARS cases or areas with community transmission of SARS. This case definition will be updated periodically as new information becomes available. Epidemiologic and laboratory investigations of SARS are ongoing. As of April 2, 2003, a total of 2,223 suspected and/or probable SARS cases have been reported to WHO from 16 countries, including the United States. The reported SARS cases include 78 deaths (case-fatality proportion: 3.5%). This report summarizes SARS cases among U.S. residents and surveillance and prevention activities in the United States.

Characterization of a novel coronavirus associated with severe acute respiratory syndrome. (5/1050)In March 2003, a novel coronavirus (SARS-CoV) was discovered in association with cases of severe acute respiratory syndrome (SARS). The sequence of the complete genome of SARS-CoV was determined, and the initial characterization of the viral genome is presented in this report. The genome of SARS-CoV is 29,727 nucleotides in length and has 11 open reading frames, and its genome organization is similar to that of other coronaviruses. Phylogenetic analyses and sequence comparisons showed that SARS-CoV is not closely related to any of the previously characterized coronaviruses. (+info)
The Genome sequence of the SARS-associated coronavirus. (6/1050)We sequenced the 29,751-base genome of the severe acute respiratory syndrome (SARS)-associated coronavirus known as the Tor2 isolate. The genome sequence reveals that this coronavirus is only moderately related to other known coronaviruses, including two human coronaviruses, HCoV-OC43 and HCoV-229E. Phylogenetic analysis of the predicted viral proteins indicates that the virus does not closely resemble any of the three previously known groups of coronaviruses. The genome sequence will aid in the diagnosis of SARS virus infection in humans and potential animal hosts (using polymerase chain reaction and immunological tests), in the development of antivirals (including neutralizing antibodies), and in the identification of putative epitopes for vaccine development.

TY - JOUR. T1 - Two palmitylated cysteine residues of the severe acute respiratory syndrome coronavirus spike (S) protein are critical for S incorporation into virus-like particles, but not for M-S co-localization. AU - Ujike, Makoto. AU - Huang, Cheng. AU - Shirato, Kazuya. AU - Matsuyama, Shutoku. AU - Makino, Shinji. AU - Taguchi, Fumihiro. PY - 2012/4. Y1 - 2012/4. N2 - The endodomain of several coronavirus (CoV) spike (S) proteins contains palmitylated cysteine residues and enables co-localization and interaction with the CoV membrane (M) protein. Depalmitylation of mouse hepatitis virus S proteins abolished this interaction, resulting in the failure of S incorporation into virions. In contrast, an immunofluorescence assay (IFA) showed that depalmitylated severe acute respiratory syndrome coronavirus (SCoV) S proteins still co-localized with the M protein in the budding site. Here, we determined the ability of depalmitylated SCoV S mutants to incorporate S into virus-like particles (VLPs). ...

An improved TaqMan technology using minor groove binder (MGB) probes was used to detect and quantify SARS-CoV in suspected patients. SARS-CoV primers and probe were designed based on the open reading frame 1b sequence, which encodes coronavirus replicase protein. A ...
Severe Acute Respiratory Syndrome Coronavirus 2, COVID-19, and the Renin-Angiotensin System | Hypertension
The coronavirus disease 2019 (COVID-19) pandemic is associated with significant morbidity and mortality throughout the world, predominantly due to lung and cardiovascular injury. The virus responsible for COVID-19-severe acute respiratory syndrome coronavirus 2-gains entry into host cells via ACE2 (angiotensin-converting enzyme 2). ACE2 is a primary enzyme within the key counter-regulatory pathway of the renin-angiotensin system (RAS), which acts to oppose the actions of Ang (angiotensin) II by generating Ang-(1-7) to reduce inflammation and fibrosis and mitigate end organ damage. As COVID-19 spans multiple organ systems linked to the cardiovascular system, it is imperative to understand clearly how severe acute respiratory syndrome coronavirus 2 may affect the multifaceted RAS. In addition, recognition of the role of ACE2 and the RAS in COVID-19 has renewed interest in its role in the pathophysiology of cardiovascular disease in general. We provide researchers with a framework of best practices ...
Severe Acute Respiratory Syndrome-associated Coronavirus in Lung Tissue - Volume 10, Number 1-January 2004 - Emerging...
Efforts to contain severe acute respiratory syndrome (SARS) have been limited by the lack of a standardized, sensitive, and specific test for SARS-associated coronavirus (CoV). We used a standardized reverse transcription-polymerase chain reaction assay to detect SARS-CoV in lung samples obtained from well-characterized patients who died of SARS and from those who died of other reasons. SARS-CoV was detected in all 22 postmortem lung tissues (to 109 viral copies/g) from 11 patients with probable SARS but was not detected in any of the 23 lung control samples (sample analysis was blinded). The sensitivity and specificity (95% confidence interval) were 100% (84.6% to 100%) and 100% (85.1% to 100%), respectively. Viral loads were significantly associated with a shorter course of illness but not with the use of ribavirin or steroids. CoV was consistently identified in the lungs of all patients who died of SARS but not in control patients, supporting a primary role for CoV in deaths.
HKU Scholars Hub: Small molecules blocking the entry of severe acute respiratory syndrome coronavirus into host cells
Severe acute respiratory syndrome coronavirus (SARS-CoV) is the pathogen of SARS, which caused a global panic in 2003. We describe here the screening of Chinese herbal medicine-based, novel small molecules that bind avidly with the surface spike protein of SARS-CoV and thus can interfere with the entry of the virus to its host cells. We achieved this by using a two-step screening method consisting of frontal affinity chromatography-mass spectrometry coupled with a viral infection assay based on a human immunodeficiency virus (HIV)-luc/SARS pseudotyped virus. Two small molecules, tetra-O-galloyl-beta-D-glucose (TGG) and luteolin, were identified, whose anti-SARS-CoV activities were confirmed by using a wild-type SARS-CoV infection system. TGG exhibits prominent anti-SARS-CoV activity with a 50% effective concentration of 4.5 microM and a selective index of 240.0. The two-step screening method described here yielded several small molecules that can be used for developing new classes of ...
An Exposed Domain in the Severe Acute Respiratory Syndrome Coronavirus Spike Protein Induces Neutralizing Antibodies | Journal...
Selecting from regions of the S protein of SARS CoV that are predicted to potentially present antigenic determinants, a small region (S-II) comprising residues 485 to 625 was expressed as a recombinant protein in E. coli. After proper refolding, the solubilized S-II fragment was shown to specifically bind the surface of Vero cells by FACS analysis. This suggests that antibodies against this region could give rise to neutralizing activities. A panel of MAbs was raised with the recombinant S-II protein. A series of tests showed that the MAbs could recognize the native S protein, block the attachment of S-II to Vero cells, and neutralize SARS CoV infection in cell culture.. Virus entry involves attachment of the S1 region to the host receptor and exposure of the fusion peptide that results from the conformational change induced by the interaction of the S1 region with the receptor. However, studies with HCoV 229E, MHV, and TGEV further defined polypeptide regions that can bind the host receptor. A ...
Predicting the recombination potential of severe acute respiratory syndrome coronavirus 2 and Middle East respiratory syndrome...
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) recently emerged to cause widespread infections in humans. SARS-CoV-2 infections have been reported in the Kingdom of Saudi Arabia, where Middle East respiratory syndrome coronavirus (MERS-CoV) causes seasonal outbreaks with a case fatality rate of ~37 %. Here we show that there exists a theoretical possibility of future recombination events between SARS-CoV-2 and MERS-CoV RNA. Through computational analyses, we have identified homologous genomic regions within the ORF1ab and S genes that could facilitate recombination, and have analysed co-expression patterns of the cellular receptors for SARS-CoV-2 and MERS-CoV, ACE2 and DPP4, respectively, to identify human anatomical sites that could facilitate co-infection. Furthermore, we have investigated the likely susceptibility of various animal species to MERS-CoV and SARS-CoV-2 infection by comparing known virus spike protein-receptor interacting residues. In conclusion, we suggest that a

Dissertation or Thesis | Evaluations Of Severe Acute Respiratory Syndrome Coronavirus Therapeutics And A Viral Capacity For...
The Severe Acute Respiratory Syndrome Coronavirus (SARS-CoV) emerged in 2002/2003, causing the deaths of almost a tenth of the 8000 individuals infected worldwide before it was controlled by public health measures. While the 2003 epidemic strain is likely extinct, the importance of coronaviruses as emergent zoonotic viruses was again realized with the emergence of a novel human coronavirus in Saudi Arabia in 2012. Despite a decade of research on SARS-CoV no approved vaccine or therapeutic yet exists, and development of broadly neutralizing and effective therapeutics for coronaviruses remains a priority. Neutralizing antibodies targeting the Spike glycoprotein (S) are both necessary and sufficient for protection against SARS-CoV, but the high genetic diversity and mutability of SARS-CoV in natural infections presents a challenge to both vaccine- and antibody-based therapeutics. Thus, an effective SARS-CoV therapeutic should provide S-specific immunity that is nonetheless broad enough to counter ...
HKU Scholars Hub: Antibody-dependent infection of human macrophages by severe acute respiratory syndrome coronavirus
Public health risks associated to infection by human coronaviruses remain considerable and vaccination is a key option for preventing the resurgence of severe acute respiratory syndrome coronavirus (SARS-CoV). We have previously reported that antibodies elicited by a SARS-CoV vaccine candidate based on recombinant, full-length SARS-CoV Spike-protein trimers, trigger infection of immune cell lines. These observations prompted us to investigate the molecular mechanisms and responses to antibody-mediated infection in human macrophages ...

UNLABELLED: The receptor binding domain (RBD) of the spike (S) glycoprotein of severe acute respiratory syndrome coronavirus (SARS-CoV) is a major target of protective immunity in vivo. Although a large number of neutralizing antibodies (nAbs) have been developed, it remains unclear if a single RBD-targeting nAb or two in combination can prevent neutralization escape and, if not, attenuate viral virulence in vivo. In this study, we used a large panel of human nAbs against an epitope that overlaps the interface between the RBD and its receptor, angiotensin-converting enzyme 2 (ACE2), to assess their cross-neutralization activities against a panel of human and zoonotic SARS-CoVs and neutralization escape mutants. We also investigated the neutralization escape profiles of these nAbs and evaluated their effects on receptor binding and virus fitness in vitro and in mice. We found that some nAbs had great potency and breadth in neutralizing multiple viral strains, including neutralization escape ...

The current outbreak of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)in China threatened humankind worldwide. The coronaviruses contains the largest RNA genome among all other known RNA viruses, therefore the disease etiology can be understood by analyzing the genome sequence of SARS-CoV-2. In this study, we used an ab-intio based computational tool VMir to scan the complete genome of SARS-CoV-2 to predict pre-miRNAs. The potential pre-miRNAs were identified by ViralMir and mature miRNAs were recognized by Mature Bayes. Additionally, predicted mature miRNAs were analysed against human genome by miRDB server to retrieve target genes. Besides that we also retrieved GO (Gene Ontology) terms for pathways, functions and cellular components. We predicted 26 mature miRNAs from genome of SARS-CoV-2 that targets human genes involved in pathways like EGF receptor signaling, apoptosis signaling, VEGF signaling, FGF receptor signaling.

In this study, we have examined the function of the SARS-CoV S protein and the contribution of other viral membrane proteins to virus fusion and entry. We suggest that, of these gene products, the S glycoprotein is necessary and sufficient for viral gene delivery. Although the origin of SARS-CoV is unknown, recent studies have suggested that it may have been transmitted from animals to humans (6, 7, 13). During the course of the SARS-CoV epidemic, molecular evolution throughout the SARS-CoV genome was detected. In addition to mutations in several regions of SARS-CoV, specific changes that involved the deletion of a 29-nucleotide region or insertion of an 82-nucleotide region in ORF8 were observed, and it is hypothesized that these changes may have facilitated the spread of the disease (7). It is possible that SARS-CoV has arisen from recombination between different coronaviruses, although the direct antecedents of the present strain are not yet defined (15, 20, 33, 36). While SARS-CoV is not ...

Emerging Viruses in Human Populations - Volume 13, Number 12-December 2007 - Emerging Infectious Disease journal - CDC
With increasing international travel and globalization of the worlds economies, changing climates, and altered human behavior and demographics, multiple viruses have emerged to occupy expanded ecologic niches, producing disease syndromes in parts of the world where they had never before existed. Because most emerging viral diseases in humans in the 21st century have been zoonotic, Emerging Viruses in Human Populations focuses on this group of viruses. The resulting overview is a book useful for anyone interested in a diverse group of viral agents that have recently elicited novel disease syndromes in human populations around the world. This text does an excellent job of encompassing a wide variety of contact-transmitted enzootic viruses including severe acute respiratory syndrome-associated coronavirus, Nipah and Hendra viruses, influenza virus, hantaviruses, monkeypox viruses, and vector-transmitted agents including Crimean-Congo hemorrhagic fever, dengue, West Nile, and Japanese encephalitis ...

Children Under 5 Could Spread Coronavirus More Than Adults- New Study - HealthTimes
CHILDREN below the age of five could be major carriers of the coronavirus as compared to adults, a new study has found.. By Michael Gwarisa According to the study Age-Related Differences in Nasopharyngeal Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) Levels in Patients With Mild to Moderate Coronavirus Disease 2019 (COVID-19), which was published in JAMA Pediatrics and led by Dr. Taylor Heald-Sargent, a pediatric infectious diseases expert at the Ann and Robert H. Lurie Childrens Hospital of Chicago, children are susceptible to infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) but generally present with mild symptoms compared with adults.. Children drive spread of respiratory and gastrointestinal illnesses in the population, but data on children as sources of SARS-CoV-2 spread are sparse. Early reports did not find strong evidence of children as major contributors to SARS-CoV-2 spread,3 but school closures early in pandemic responses thwarted ...
Wikipedia - Severe acute respiratory syndrome coronavirus 2 - Corona Virus Help
The first known infections from the SARS-CoV-2 strain were discovered in Wuhan, China. The original source of viral transmission to humans and when the strain became pathogenic remains unclear. Because many of the first individuals found to be infected by the virus were workers at the Huanan Seafood Market, it has been suggested that the strain might have originated from the market. However, other research indicates that visitors may have introduced the virus to the market, which then facilitated rapid expansion of the infections.. Research into the natural reservoir of the virus strain that caused the 2002-2004 SARS outbreak has resulted in the discovery of many SARS-like bat coronaviruses, most originating in the Rhinolophus genus of horseshoe bats, and two viral nucleic acid sequences found in samples taken from Rhinolophus sinicus show a resemblance of 80% to SARS-CoV-2. A third viral nucleic acid sequence from Rhinolophus affinis, collected ...
RePub, Erasmus University Repository: Severe Acute Respiratory Syndrome Coronavirus 2-Specific Antibody Responses in...
A new coronavirus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has recently emerged to cause a human pandemic. Although molecular diagnostic tests were rapidly developed, serologic assays are still lacking, yet urgently needed. Validated serologic assays are needed for contact tracing, identifying the viral reservoir, and epidemiologic studies. We developed serologic assays for detection of SARS-CoV-2 neutralizing, spike protein-specific, and nucleocapsid-specific antibodies. Using serum samples from patients with PCR-confirmed SARS-CoV-2 infections, other coronaviruses, or other respiratory pathogenic infections, we validated and tested various antigens in different in-house and commercial ELISAs. We demonstrated that most PCR-confirmed SARS-CoV-2-infected persons seroconverted by 2 weeks after disease onset. We found that commercial S1 IgG or IgA ELISAs were of lower specificity, and sensitivity varied between the 2 assays; the IgA ELISA showed higher sensitivity. Overall, ...
Mechanisms of Host Defense following Severe Acute Respiratory Syndrome-Coronavirus (SARS-CoV) Pulmonary Infection of Mice | The...
This study demonstrates that B6 mice can be productively infected by SARS-CoV in the bronchial and bronchiolar epithelium of the respiratory tract, and that virus is rapidly cleared through a mechanism independent of NK cells, NK-T cells, and T and B lymphocytes. Virus is able to spread to the brain at late time points when it has already been cleared by the lung, and may spread to multiple other organs. SARS-CoV induces dramatic up-regulation of a subset of inflammatory chemokines and the chemokine receptor CXCR3, but interestingly this occurs without detectable expression of classic proinflammatory and immunoregulatory cytokines and without evoking marked leukocyte infiltration of the lung. Overall, infected B6 mice do not develop overt disease, but their weight gain is slowed relative to mock-infected controls.. The work confirms our previously published finding that BALB/c mice can be productively and transiently infected in the terminal bronchioles. The susceptibility of the two strains to ...

Chloroquine is a potent inhibitor of SARS coronavirus infection and spread | Virology Journal | Full Text
Severe acute respiratory syndrome (SARS) is caused by a newly discovered coronavirus (SARS-CoV). No effective prophylactic or post-exposure therapy is currently available. We report, however, that chloroquine has strong antiviral effects on SARS-CoV infection of primate cells. These inhibitory effects are observed when the cells are treated with the drug either before or after exposure to the virus, suggesting both prophylactic and therapeutic advantage. In addition to the well-known functions of chloroquine such as elevations of endosomal pH, the drug appears to interfere with terminal glycosylation of the cellular receptor, angiotensin-converting enzyme 2. This may negatively influence the virus-receptor binding and abrogate the infection, with further ramifications by the elevation of vesicular pH, resulting in the inhibition of infection and spread of SARS CoV at clinically admissible concentrations. Chloroquine is effective in preventing the spread of SARS CoV in cell culture. Favorable inhibition

Four Coronavirus Proteins to Aid the Fight Against COVID-19 - Scientist Blog
For detecting the Coronavirus as well as for developing vaccines against it the virus specific proteins are promising targets for scientists. Here we will describe some of the most important Coronavirus proteins:. SARS-CoV Spike Protein. The coronavirus spike contains three segments: a large ectodomain, a single-pass transmembrane anchor and a short intracellular tail. The ectodomain consists of a receptor-binding subunit S1 and a membrane-fusion subunit S2. During virus entry, S1 binds to a receptor on the host cell surface for viral attachment, and S2 fuses the host and viral membranes, allowing viral genomes to enter host cells.. SARS-CoV Nucleocapsid Protein. Of all the coronaviral structural proteins, the N protein is the most abundant throughout infection, both in mRNA and protein levels. Compared to the mRNA levels of other structural genes, the mRNA of the N protein is expressed three to ten times higher at 12-hour post-infection.. SARS-CoV Envelope Protein. The Envelope (E) protein is ...

Molecular modelling of S1 and S2 subunits of SARS coronavirus spike glycoprotein - Research Repository
The S1 and S2 subunits of the spike glycoprotein of the coronavirus which is responsible for the severe acute respiratory syndrome (SARS) have been modelled, even though the corresponding amino acid sequences were not suitable for tertiary structure predictions with conventional homology and/or threading procedures. An indirect search for a protein structure to be used as a template for 3D modelling has been performed on the basis of the genomic organisation similarity generally exhibited by coronaviruses. The crystal structure of Clostridium botulinum neurotoxi n B appeared to be structurally adaptable to human and canine coronavirus spike protein sequences and it was successfully used to model the two subunits of SARS coronavirus spike glycoprotein. The overall shape and the surface hydrophobicity of the two subunits in the obtained models suggest the localisation of the most relevant regions for their activity. © 2003 Elsevier Inc.

Host responses contributing to the attenuation of severe acute respiratory syndrome coronaviruses missing E protein domains -...
Severe acute respiratory syndrome coronavirus (SARS-CoV) causes a respiratory disease leading to death in 10% of the infected people. A mouse adapted SARS-CoV lacking the envelope (E) protein (rSARS-CoV-MA15-ΔE) is attenuated in vivo. To identify E protein domains and host responses that contribute to rSARS-CoV-MA15-ΔE attenuation, several mutants (rSARS-CoV-MA15-E*) containing point mutations or deletions in the amino-terminal or the carboxy-terminal regions of E protein, respectively, were generated. Amino acid substitutions in the amino terminus, or deletion of domains in the internal carboxy terminal region of E protein led to viral attenuation. Attenuated viruses induced minimal lung injury and limited neutrophil influx to the lungs but, interestingly, increased CD4+ and CD8+ T cell counts in BALB/c mice. To analyze the host responses leading to rSARS-CoV-MA15-E* attenuation, the differential gene expression elicited by the native virus and the mutant ones in infected cells was analyzed. The

Evaluation of organ function in patients with severe COVID-19 infections | Medicina Clínica
Discussion. The novel coronavirus is a member of the β coronavirus type, with humans as the host. Since the first human coronavirus (HCoV) was isolated from the nasal secretions of patients with the common cold in 1965, six different strains of CoV are known to infect humans. These CoV strains include severe acute respiratory syndrome coronavirus (SARS-CoV), Middle East respiratory syndrome coronavirus (MERS-CoV), and the common cold viruses in individuals with strong immunity (such as 229E, OC43, NL63, and HKU1).1 This novel coronavirus, COVID-19, has more than 85% homology with the previously detected bat coronavirus (a SARS-related coronavirus species, that is, SARS coronavirus). However, there are clear differences in the genetic characteristics of COVID-19 compared with SARS-CoV and MERS-CoV.5. Through observation of the current global epidemic situation, we can demonstrate the infectivity and pathogenicity of COVID-19. To the treatment of COVID-19, the main treatment is antiviral therapy, ...

Together with the Spring Event exodus, an outbreak appeared unavoidable. This problem attracted the interest of the Chinese language Middle for Disease Control and Avoidance (CDC), who instantly released a crisis response. The World Health Organization (WHO) also responded promptly and declared the outbreak a public health emergency of international concern (PHEIC). The causative agent of the unidentified pneumonia has been confirmed as a novel coronavirus by sequencing and aetiological investigations by several independent laboratories in China. Following the isolation of the new coronavirus, it was found to be distinct both from Middle East respiratory syndrome coronavirus (MERS-CoV) and severe acute respiratory syndrome coronavirus (SARS-CoV) [1,2]. Coronaviruses are ...
Severe acute respiratory syndrome - Simple English Wikipedia, the free encyclopedia
Severe acute respiratory syndrome (SARS)  was an atypical pneumonia. It started in November 2002 in Guangdong Province, in the city of Foshan, of the Peoples Republic of China. The disease was caused by the SARS coronavirus (SARS CoV), a new coronavirus. It was also a part-time STD, it can be spread through both sexual and casual contact. SARS was first reported in Asia in February 2003. Over the next few months, the illness spread to more than 24 countries in Asia, North America, South America, and Europe before the SARS global outbreak of 2003 was contained. According to the World Health Organization (WHO), a total of 8098 people worldwide became sick with SARS during the 2003 outbreak; 774 of these died. After the Chinese government suppressed news of the SARS outbreak, the disease spread rapidly, reaching Hong Kong and Vietnam in late February 2003, and then to other countries via international travellers. The last case in this outbreak occurred in June 2003. There were a total of ...

Dynamic Profiles of Cytokine/Chemokine in Severe Acute Respiratory Syndrome - Tabular View - ClinicalTrials.gov
Severe acute respiratory syndrome (SARS) is an emerging infectious disease caused by a novel coronavirus (SARS-CoV). The major clinical features of SARS include fever, dyspnea, lymphopenia, and a rapid progression of pulmonary infiltrates on chest radiologic images. The SARS-related deaths have resulted mainly from pulmonary complications, including progressive respiratory failure due to alveolar damage and acute respiratory distress syndrome (ARDS). Pathological changes in SARS suggest that SARS sequelae such as infiltration of PMN in lung tissue, multiple organ dysfunction and ARDS have been associated with cytokines and chemokine dysregulation. Some patients still manifested lung injury at a time when the viral load was falling also supports the immune nature of the lung damage. We therefore undertook an analysis of dynamic production of cytokine/chemokines in SARS patients with an initial normal chest radiograph in order to improve understanding of disease pathogenesis and improve patient ...
Severe acute respiratory syndrome (SARS) | Go Ask Alice!
Dear Reader,. Thanks for the props! And glad to be of service.. SARS is a serious health concern, and it can be dangerous if you come into contact with it. However, you dont necessarily need to be concerned. The media grasped onto the sensationalized story of SARS because of its rapid spread made possible by the relatively new phenomenon of extensive and frequent world travel and the fast rate of transmission. Luckily the virus was quickly isolated and contained only months after its initial out-break.. SARS, which is an acronym for Severe Acute Respiratory Syndrome, is a contagious and sometimes fatal respiratory illness that is actually a severe form of pneumonia. It is caused by a strain of the coronavirus, which is also the family of viruses that causes the common cold. SARS first appeared in China in 2002, and within six weeks had spread worldwide. Within a month and a half, 8,000 people were infected and 800 had died. SARS dramatically taught us how rapidly world travel can spread ...
Severe Acute Respiratory Syndrome (SARS) - Health, Disease, Quarantine, and Officials - JRank Articles
Severe acute respiratory syndrome (SARS) is the first emergent and highly transmissible viral disease to appear during the twenty-first century. Patients with SARS develop flu-like fever, headache, malaise, dry cough and other breathing difficulties. Many patients develop pneumonia, and in 5-10% of cases, the pneumonia and other complications are severe enough to cause death. SARS is caused by a virus that is transmitted usually from person to person-predominantly by the aerosolized droplets of virus infected material.. SARS cases provided a test of recent reforms in International Health Regulations designed to increase surveillance and reporting of infectious diseases-and to enhance cooperation in preventing the international spread of disease. Although not an act of bioterrorism, because the very same epidemiologic principles and isolation protocols might be used to both initially determine and initially respond to an act of bioterrorism, intelligence and public heath officials closely ...

Background Viral load kinetics and duration of viral shedding are important determinants for disease transmission. We aimed to characterise viral load dynamics, duration of viral RNA shedding, and viable virus shedding of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in various body fluids, and to compare SARS-CoV-2, SARS-CoV, and Middle East respiratory syndrome coronavirus (MERS-CoV) viral dynamics. Methods In this systematic review and meta-analysis, we searched databases, including MEDLINE, Embase, Europe PubMed Central, medRxiv, and bioRxiv, and the grey literature, for research articles published between Jan 1, 2003, and June 6, 2020. We included case series (with five or more participants), cohort studies, and randomised controlled trials that reported SARS-CoV-2, SARS-CoV, or MERS-CoV infection, and reported viral load kinetics, duration of viral shedding, or viable virus. Two authors independently extracted data from published studies, or contacted authors to request ...
Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) and coronavirus disease 19 (COVID-19) - anatomic pathology...
The world is currently witnessing a major devastating pandemic of Coronavirus disease-2019 (COVID-19). This disease is caused by a novel coronavirus named Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2). It primarily affects the respiratory tract and particularly the lungs. The virus enters the cell by attaching its spike-like surface projections to the angiotensin-converting enzyme-2 (ACE-2) expressed in various tissues. Though the majority of symptomatic patients have mild flu-like symptoms, a significant minority develop severe lung injury with acute respiratory distress syndrome (ARDS), leading to considerable morbidity and mortality. Elderly patients with previous cardiovascular comorbidities are particularly susceptible to severe clinical manifestations. Currently, our limited knowledge of the pathologic findings is based on post-mortem biopsies, a few limited autopsies, and very few complete autopsies. From these reports, we know that the virus can be found in various organs but the
Keep Your Employees Safe from the MERS Virus
As more companies send employees on global travel, its important for safety and health managers to have a proper infection control system. If an employee contracts an infectious disease, the possibility of spreading it throughout the company could develop into a serious problem for the employer.. For instance, between November 2002 and July 2003, an outbreak of a terrible viral respiratory illness caused by a coronavirus occurred in South China. This disease, Severe Acute Respiratory Syndrome coronavirus (SARS-CoV), was on the verge of becoming a pandemic. According to the World Health Organization (WHO), there were 8,098 cases and 774 deaths worldwide. In general, SARS begins with a high fever and can lead to other symptoms such as headaches, an overall feeling of discomfort and body aches. The illness spread to more than two dozen countries before the 2003 outbreak was contained.. In April 2012, a new coronavirus emerged in the Middle East: Middle East Respiratory Syndrome Coronavirus ...

Severe acute respiratory syndrome (SARS) is a highly contagious, serious and potentially life-threatening form of pneumonia. (SARS (Severe syndrome))
Viral load dynamics and disease severity in patients infected with SARS-CoV-2 in Zhejiang province, China, January-March 2020:...
We have systematically described the clinical characteristics of 96 patients with covid-19 and described the dynamic changes of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) loads and disease progression in 3497 samples of multiple types, revealing the interaction between SARS-CoV-2 replication and clearance by host defence mechanisms. The median duration of virus in respiratory samples was 18 days, which was consistent with the median duration of 20 days for Middle East respiratory syndrome (MERS).12 Peak viral shedding in respiratory specimens of patients with severe acute respiratory syndrome (SARS) occurred after about 10 to 12 days from symptom onset,1314 which is similar to the peak observed for SARS-CoV-2 in our study. Consistent with earlier reports of SARS-CoV-2,15 we found differences in the viral load in patients with different disease severities, those with severe disease showing a significantly higher viral load than those with mild disease, which suggests that viral ...
Preliminary Clinical Description of Severe Acute Respiratory Syndrome
On March 21, 2003, this report was posted on the MMWR website (http://www.cdc.gov/mmwr). Severe acute respiratory syndrome (SARS) is a condition of unknown etiology that has been described in patients in Asia, North America, and Europe. This report summarizes the clinical description of patients with SARS based on information collected since mid-February 2003 by the World Health Organization (WHO), Health Canada, and CDC in collaboration with health authorities and clinicians in Hong Kong, Taiwan, Bangkok, Singapore, the United Kingdom, Slovenia, Canada, and the United States. This information is preliminary and limited by the broad and necessarily nonspecific case definition. As of March 21, 2003, the majority of patients identified as having SARS have been adults aged 25--70 years who were previously healthy. Few suspected cases of SARS have been reported among children aged ,15 years. The incubation period for SARS is typically 2--7 days; however, isolated reports have suggested an incubation ...

Should Remdesivir Be Used for the Treatment of Patients With COVID-19? by Amir Qaseem, Jennifer Yost et al.
Remdesivir, a broad-spectrum antiviral agent administered intravenously, was developed and studied as a potential treatment for Ebola virus disease and Marburg virus infection. In vitro and in vivo preclinical studies found antiviral activity for remdesivir against corona-like viruses, including Middle East respiratory syndrome coronavirus, severe acute respiratory syndrome coronavirus (SARS-CoV-1), the circulating human coronaviruses HCoV-OC42 and HCoV-229E, and SARS-CoV-2. Currently, the effectiveness of remdesivir is being tested as a treatment for patients infected with SARS-CoV-2 (COVID-19) and has been authorized for emergency use for treating COVID-19, by the U.S. Food and Drug Administration in the United States, and in other countries. The American College of Physicians (ACP) Scientific Medical Policy Committee (SMPC) based these rapid and living practice points on a systematic evidence review conducted by the U.S. Department of Veterans Affairs (VA) Evidence Synthesis Program in Minneapolis,

Covid 19 Research Clinical Trials by Shray Alag
The novel coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS CoV-2) has been discovered recently in December 2019 from wuhan city in China to spread in more than 40 countries allover the world. This disease has gain the attention of all nations after it has been stated as a pandemic by the World Health Organization (WHO) in March 12, 2020. Currently no treatment has been proved to be efficient in the treatment of infected patients by COVID-19. Natural honey has been demonstrated as potent antimicrobial in many research investigations and has been considered a good alternative for antiviral drugs for the treatment of some viral infections. The investigators aim to study the efficacy of natural honey in the treatment of COVID-19 patients in this randomized , multicenter, controlled trial, comparing honey in one arm to standard care in the other arm. ...
Scientists Identify SARS Receptor - Scientific American
Severe acute respiratory syndrome (SARS) originated in southern China in November 2002, and soon spread to people on six continents, killing nearly 800 people all told. For the first time, researchers have identified a crucial SARS receptor in vivo that helps explain how and why SARS infection causes lung failure. The findings should help researchers treat other diseases that compromise lung function. Previous research using cell lines had identified ACE2, a protein involved in regulating blood pressure, as a potential SARS receptor. Now Josef Penninger of the Institute of Molecular Biotechnology (IMBA) in Vienna, Austria, and his colleagues have tested the hypothesis in mice. In a paper published online yesterday by Nature Medicine, they report that SARS infection, and specifically the SARS protein known as Spike, reduces ACE2 expression. As a result, blood vessels in the lungs become damaged and the lung becomes flooded as a result. In a second paper published in the current issue of the ...
Safety considerations with chloroquine, hydroxychloroquine and azithromycin in the management of SARS-CoV-2 infection | CMAJ
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has spread rapidly around the globe in recent months. With deaths from its associated disease, coronavirus disease 2019 (COVID-19), projected to reach into the millions and a vaccine unlikely in the near term, the search is on for existing drugs that might prevent COVID-19 or improve outcomes for patients who have COVID-19. Chloroquine and its derivative hydroxychloroquine, which have been used for decades in the treatment and prevention of malaria as well as chronic inflammatory diseases such as rheumatoid arthritis and systemic lupus erythematosus, have received much attention as potential therapies.. Optimism for repurposing these drugs stems from 2 lines of evidence: inhibition of Coronaviridae (including SARS and SARS-CoV-2) in vitro1-3 and preliminary but contradictory clinical data from studies conducted in China and France.4-8 Of these, an open-label nonrandomized study by Gautret and colleagues5 that involved treatment using ...

Quinacrine (Qx), a molecule used as an antimalarial, has shown anticancer, antiprion, and antiviral activity. The most relevant antiviral activities of Qx are related to its ability to raise pH in acidic organelles, diminishing viral enzymatic activity for viral cell entry, and its ability to bind to viral DNA and RNA. Moreover, Qx has been used as an immunomodulator in cutaneous lupus erythematosus and various rheumatological diseases, by inhibiting phospholipase A2 modulating the Th1/Th2 response. The aim of this study was to evaluate the potential antiviral effect of Qx against denominated severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in Vero E6 cells. The cytotoxicity of Qx in Vero E6 cells was determined by the MTT assay. Afterwards, Vero E6 cells were infected with SARS-CoV-2 at different multiplicities of infections (MOIs) of 0.1 and 0.01 in the presence of Qx (0-30 µM) to determinate the half maximal effective concentration (EC50). After 48 h, the effect of Qx ...

- But it's early days to make any definite statements because viruses can change and mutate very rapidly, so what is right today may be wrong tomorrow," he said. (nbcnews.com)
- Partly due to SETREP-ID, "[w]hen COVID-19 emerged, we already had ethics and protocols in place so we could rapidly start looking at the virus and immune system in great detail," says study co-author Dr. Irani Thevarajan. (bingj.com)
- His disease course was remarkably mild, and the virus cleared rapidly. (frontiersin.org)
- The study reasoned that this is partly because RNA viruses have a high mutation rate, so they tend to keep their gene count low to prevent a large number of mutations. (thehindubusinessline.com)
- This is concordant with recent clinical observations which show that COVID-19 exhibits a reduced interferon response in comparison to other respiratory viruses such as influenza and SARS. (news-medical.net)
- We showed that even though COVID-19 is caused by a new virus, in an otherwise healthy person, a robust immune response across different cell types was associated with clinical recovery, similar to what we see in influenza," says study co-author Prof. Katherine Kedzierska. (bingj.com)
- Here, we report a field-effect transistor (FET)-based biosensing device for detecting SARS-CoV-2 in clinical samples. (unboundmedicine.com)
- In addition, the FET sensor successfully detected SARS-CoV-2 in culture medium (limit of detection [LOD]: 1.6 × 101 pfu/mL) and clinical samples (LOD: 2.42 × 102 copies/mL). (unboundmedicine.com)
- Respiratory viruses aren't usually known to cause serious kidney problems. (washingtontimes.com)
- China has admitted that the virus is spreading into more remote provinces and has dispatched emergency SARS teams. (newscientist.com)
