Acute and persistent infection of human neural cell lines by human coronavirus OC43. (1/49)

Human coronaviruses (HuCV) are recognized respiratory pathogens. Data accumulated by different laboratories suggest their neurotropic potential. For example, primary cultures of human astrocytes and microglia were shown to be susceptible to an infection by the OC43 strain of HuCV (A. Bonavia, N. Arbour, V. W. Yong, and P. J. Talbot, J. Virol. 71:800-806, 1997). We speculate that the neurotropism of HuCV will lead to persistence within the central nervous system, as was observed for murine coronaviruses. As a first step in the verification of our hypothesis, we have characterized the susceptibility of various human neural cell lines to infection by HuCV-OC43. Viral antigen, infectious virus progeny, and viral RNA were monitored during both acute and persistent infections. The astrocytoma cell lines U-87 MG, U-373 MG, and GL-15, as well as neuroblastoma SK-N-SH, neuroglioma H4, oligodendrocytic MO3.13, and the CHME-5 immortalized fetal microglial cell lines, were all susceptible to an acute infection by HuCV-OC43. Viral antigen and RNA and release of infectious virions were observed during persistent HuCV-OC43 infections ( approximately 130 days of culture) of U-87 MG, U-373 MG, MO3.13, and H4 cell lines. Nucleotide sequences of RNA encoding the putatively hypervariable viral S1 gene fragment obtained after 130 days of culture were compared to that of initial virus input. Point mutations leading to amino acid changes were observed in all persistently infected cell lines. Moreover, an in-frame deletion was also observed in persistently infected H4 cells. Some point mutations were observed in some molecular clones but not all, suggesting evolution of the viral population and the emergence of viral quasispecies during persistent infection of H4, U-87 MG, and MO3.13 cell lines. These results are consistent with the potential persistence of HuCV-OC43 in cells of the human nervous system, accompanied by the production of infectious virions and molecular variation of viral genomic RNA.  (+info)

Pigs with highly prevalent antibodies to human coronavirus and swine haemagglutinating encephalomyelitis virus in the Tohoku District of Japan. (2/49)

From 1985 to 1988, a total of 2496 swine sera from 60 farms in the Tohoku District of the Honshu Island of Japan were examined for antibodies to swine haemagglutinating encephalomyelitis virus (HEV), human coronavirus (HCV) and bovine coronavirus (BCV) by haemagglutination-inhibition (HI) test. Antibodies to HEV 67N strain and HCV OC43 strain were highly prevalent with positivity rates of 82.1 and 91.4%, respectively, while seropositivity rate to BCV Kakegawa strain was 44.2%. No clinical signs of HEV infection were noticed in any farms including farms with relatively high seropositivity. The results suggested that HCV or antigenitically related virus(es) as well as HEV might be perpetuated in swine in the Tohoku District.  (+info)

Neuroinvasion by human respiratory coronaviruses. (3/49)

Human coronaviruses (HCoV) cause common colds but can also infect neural cell cultures. To provide definitive experimental evidence for the neurotropism and neuroinvasion of HCoV and its possible association with multiple sclerosis (MS), we have performed an extensive search and characterization of HCoV RNA in a large panel of human brain autopsy samples. Very stringent reverse transcription-PCR with two primer pairs for both viral strains (229E and OC43), combined with Southern hybridization, was performed on samples from 90 coded donors with various neurological diseases (39 with MS and 26 with other neurological diseases) or normal controls (25 patients). We report that 44% (40 of 90) of donors were positive for 229E and that 23% (21 of 90) were positive for OC43. A statistically significant higher prevalence of OC43 in MS patients (35.9%; 14 of 39) than in controls (13.7%; 7 of 51) was observed. Sequencing of nucleocapsid protein (N) gene amplicons revealed point mutations in OC43, some consistently found in three MS patient brains and one normal control but never observed in laboratory viruses. In situ hybridization confirmed the presence of viral RNA in brain parenchyma, outside blood vessels. The presence of HCoV in human brains is consistent with neuroinvasion by these respiratory pathogens. Further studies are needed to distinguish between opportunistic and disease-associated viral presence in human brains.  (+info)

Characterization of a coronavirus isolated from a diarrheic foal. (4/49)

A coronavirus was isolated from feces of a diarrheic foal and serially propagated in human rectal adenocarcinoma (HRT-18) cells. Antigenic and genomic characterizations of the virus (isolate NC99) were based on serological comparison with other avian and mammalian coronaviruses and sequence analysis of the nucleocapsid (N) protein gene. Indirect fluorescent-antibody assay procedures and virus neutralization assays demonstrated a close antigenic relationship with bovine coronavirus (BCV) and porcine hemagglutinating encephalomyelitis virus (mammalian group 2 coronaviruses). Using previously described BCV primers, the N protein gene of isolate NC99 was amplified by a reverse transcriptase PCR (RT-PCR) procedure. The RT-PCR product was cloned into pUC19 and sequenced; the complete N protein of NC99 (446 amino acids) was then compared with published N protein sequences of other avian and mammalian coronaviruses. A high degree of identity (89.0 to 90.1%) was observed between the N protein sequence of NC99 and published sequences of BCV (Mebus and F15 strains) and human coronavirus (strain OC43); only limited identity (<25%) was observed with group 1 and group 3 coronaviruses. Based on these findings, the virus has been tentatively identified as equine coronavirus (ECV). ECV NC99 was determined to have close antigenic and/or genetic relationships with mammalian group 2 coronaviruses, thus identifying it as a member of this coronavirus antigenic group.  (+info)

Vacuolating encephalitis in mice infected by human coronavirus OC43. (5/49)

Involvement of viruses in human neurodegenerative diseases and the underlying pathologic mechanisms remain generally unclear. Human respiratory coronaviruses (HCoV) can infect neural cells, persist in human brain, and activate myelin-reactive T cells. As a means of understanding the human infection, we characterized in vivo the neurotropic and neuroinvasive properties of HCoV-OC43 through the development of an experimental animal model. Virus inoculation of 21-day postnatal C57BL/6 and BALB/c mice led to a generalized infection of the whole CNS, demonstrating HCoV-OC43 neuroinvasiveness and neurovirulence. This acute infection targeted neurons, which underwent vacuolation and degeneration while infected regions presented strong microglial reactivity and inflammatory reactions. Damage to the CNS was not immunologically mediated and microglial reactivity was instead a consequence of direct virus-mediated neuronal injury. Although this acute encephalitis appears generally similar to that induced by murine coronaviruses, an important difference rests in the prominent spongiform-like degeneration that could trigger neuropathology in surviving animals.  (+info)

Frequent detection of human coronaviruses in clinical specimens from patients with respiratory tract infection by use of a novel real-time reverse-transcriptase polymerase chain reaction. (6/49)

During the past years, human coronaviruses (HCoVs) have been increasingly identified as pathogens associated with more-severe respiratory tract infection (RTI). Diagnostic tests for HCoVs are not frequently used in the routine setting. It is likely that, as a result, the precise role that HCoVs play in RTIs is greatly underestimated. We describe a rapid, sensitive, and highly specific quantitative real-time reverse-transcriptase polymerase chain reaction (RT-PCR) for the detection of HCoV that can easily be implemented in the routine diagnostic setting. HCoV was detected in 28 (11%) of the 261 clinical specimens obtained from patients presenting with symptoms of RTI ranging from common cold to severe pneumonia. Only 1 (0.4%) of the 243 control specimens obtained from patients without symptoms of RTI showed the presence of HCoV. We conclude that HCoVs can be frequently detected in patients presenting with RTI. Real-time RT-PCR provides a tool for large-scale epidemiological studies to further clarify the role that coronavirus infection plays in RTI in humans.  (+info)

Human respiratory coronavirus OC43: genetic stability and neuroinvasion. (7/49)

The complete genome sequences of the human coronavirus OC43 (HCoV-OC43) laboratory strain from the American Type Culture Collection (ATCC), and a HCoV-OC43 clinical isolate, designated Paris, were obtained. Both genomes are 30,713 nucleotides long, excluding the poly(A) tail, and only differ by 6 nucleotides. These six mutations are scattered throughout the genome and give rise to only two amino acid substitutions: one in the spike protein gene (I958F) and the other in the nucleocapsid protein gene (V81A). Furthermore, the two variants were shown to reach the central nervous system (CNS) after intranasal inoculation in BALB/c mice, demonstrating neuroinvasive properties. Even though the ATCC strain could penetrate the CNS more effectively than the Paris 2001 isolate, these results suggest that intrinsic neuroinvasive properties already existed for the HCoV-OC43 ATCC human respiratory isolate from the 1960s before it was propagated in newborn mouse brains. It also demonstrates that the molecular structure of HCoV-OC43 is very stable in the environment (the two variants were isolated ca. 40 years apart) despite virus shedding and chances of persistence in the host. The genomes of the two HCoV-OC43 variants display 71, 53.1, and 51.2% identity with those of mouse hepatitis virus A59, severe acute respiratory syndrome human coronavirus Tor2 strain (SARS-HCoV Tor2), and human coronavirus 229E (HCoV-229E), respectively. HCoV-OC43 also possesses well-conserved motifs with regard to the genome sequence of the SARS-HCoV Tor2, especially in open reading frame 1b. These results suggest that HCoV-OC43 and SARS-HCoV may share several important functional properties and that HCoV-OC43 may be used as a model to study the biology of SARS-HCoV without the need for level three biological facilities.  (+info)

Complete genomic sequence of human coronavirus OC43: molecular clock analysis suggests a relatively recent zoonotic coronavirus transmission event. (8/49)

Coronaviruses are enveloped, positive-stranded RNA viruses with a genome of approximately 30 kb. Based on genetic similarities, coronaviruses are classified into three groups. Two group 2 coronaviruses, human coronavirus OC43 (HCoV-OC43) and bovine coronavirus (BCoV), show remarkable antigenic and genetic similarities. In this study, we report the first complete genome sequence (30,738 nucleotides) of the prototype HCoV-OC43 strain (ATCC VR759). Complete genome and open reading frame (ORF) analyses were performed in comparison to the BCoV genome. In the region between the spike and membrane protein genes, a 290-nucleotide deletion is present, corresponding to the absence of BCoV ORFs ns4.9 and ns4.8. Nucleotide and amino acid similarity percentages were determined for the major HCoV-OC43 ORFs and for those of other group 2 coronaviruses. The highest degree of similarity is demonstrated between HCoV-OC43 and BCoV in all ORFs with the exception of the E gene. Molecular clock analysis of the spike gene sequences of BCoV and HCoV-OC43 suggests a relatively recent zoonotic transmission event and dates their most recent common ancestor to around 1890. An evolutionary rate in the order of 4 x 10(-4) nucleotide changes per site per year was estimated. This is the first animal-human zoonotic pair of coronaviruses that can be analyzed in order to gain insights into the processes of adaptation of a nonhuman coronavirus to a human host, which is important for understanding the interspecies transmission events that led to the origin of the severe acute respiratory syndrome outbreak.  (+info)

Human coronavirus OC43 (HCoV-OC43) is divided into genotypes A-H based on genetic recombination including the spike (S) gene. To investigate the longitudinal transition of phylogenetic feature of HCoV-OC43 S gene in a community, phylogenetic analysis of the S1 region of S gene was conducted using 208 strains detected in Yamagata during 2010-2017 with reference strains of genotype. The S1 sequences were divisible into four groups: A-D. All Yamagata strains belonged to either group B or group D. In group B, 46 (90.2%) out of 51 Yamagata strains were clustered with those of genotype E reference strains (cluster E). In group D, 28 (17.8%) and 122 (77.7%) out of 157 Yamagata strains were clustered respectively with genotype F and genotype G reference strains. In cluster G, 28 strains formed a distinct cluster. Monthly distributions of HCoV-OC43 in Yamagata in 2010-2017 revealed that group B and group D appeared one after another. In group B, the cluster E strains were prevalent recurrently. In ...
The Coronaviridae family, an enveloped RNA virus family, and, more particularly, human coronaviruses (HCoV), were historically known to be responsible for a large portion of common colds and other upper respiratory tract infections. HCoV are now known to be involved in more serious respiratory diseases, i.e. bronchitis, bronchiolitis or pneumonia, especially in young children and neonates, elderly people and immunosuppressed patients. They have also been involved in nosocomial viral infections. In 2002-2003, the outbreak of severe acute respiratory syndrome (SARS), due to a newly discovered coronavirus, the SARS-associated coronavirus (SARS-CoV); led to a new awareness of the medical importance of the Coronaviridae family. This pathogen, responsible for an emerging disease in humans, with high risk of fatal outcome; underline the pressing need for new approaches to the management of the infection, and primarily to its prevention. Another interesting feature of coronaviruses is their potential

Human coronaviruses are common throughout the world and were first identified in the mid-1960s. Seven different coronaviruses, that scientists know of, can infect people and make them sick.. Common human coronaviruses, including types 229E, NL63, OC43, and HKU1, usually cause mild to moderate upper-respiratory tract illnesses, like the common cold. Most people get infected with these viruses at some point in their lives. These illnesses usually only last for a short amount of time. Human coronaviruses can sometimes cause lower-respiratory tract illnesses, such as pneumonia or bronchitis. This is more common in people with cardiopulmonary disease, people with weakened immune systems, infants, and older adults.. Two other human coronaviruses, MERS-CoV and SARS-CoV, have been known to frequently cause severe symptoms. MERS symptoms usually include fever, cough, and shortness of breath which often progress to pneumonia. About 3 or 4 out of every 10 patients reported with MERS have died. MERS cases ...

Respiratory viruses infect the human upper respiratory tract, mostly causing mild diseases. However, in vulnerable populations, such as newborns, infants, the elderly and immune-compromised individuals, these opportunistic pathogens can also affect the lower respiratory tract, causing a more severe disease (e.g., pneumonia). Respiratory viruses can also exacerbate asthma and lead to various types of respiratory distress syndromes. Furthermore, as they can adapt fast and cross the species barrier, some of these pathogens, like influenza A and SARS-CoV, have occasionally caused epidemics or pandemics, and were associated with more serious clinical diseases and even mortality. For a few decades now, data reported in the scientific literature has also demonstrated that several respiratory viruses have neuroinvasive capacities, since they can spread from the respiratory tract to the central nervous system (CNS). Viruses infecting human CNS cells could then cause different types of encephalopathy, including

The Spike protein exists in two structurally distinct conformations: pre-fusion and post-fusion. In its pre-fusion state, Spike is a closed trimer and RBDs are buried in the inner S1 head-trimer, at the interface between each protomer [2]. This closed conformation exerts a physical constraint on the S2 subunit until specific proteases cleave the S1/S2 and S2 sites [3]. The exact mechanisms driving the opening of an S1-CTD domain and the subsequent exposition of RBD so that it can bind the ACE2 receptor are not elucidated yet. It has been proposed that the S protein is cleaved into S1 and S2 subunits by proteases, including furin, the host surface-associated transmembrane protease serine 2 (TMPRSS2), and the endocytic cathepsin L [9-12]. S1 binds to ACE2 through its RBD, and S2 is further cleaved and activated by TMPRSS2 and/or cathepsin L [9, 10]. Together these actions result in host-viral membrane fusion and release of the viral RNA genome into the host cell cytoplasm. ...

http://philosophers-stone.info/wp-content/uploads/2020/11/The-scam-has-been-confirmed-Dsalud-November-2020.pdf). Have any human coronaviruses been isolated?. the alleged isolation work of suspected human coronaviruses 229E (said to have been isolated in 1965), OC43 (in 1967), SARS-CoV (in 2003), NL63 (in 2004), HKU1 (in 2005) and MERSCoV (in 2012).. In essence, NOT ONE OF THE SEVEN SUPPOSED HUMAN CORONAVIRUS HAS REALLY BEEN ISOLATED. The only thing that has been different between them are the laboratory procedures and techniques that were becoming progressively more sophisticated which, in this case, has implied not a greater accuracy but a greater capacity for deception and self-deception that has culminated in the virtual manufacture of the SARS-CoV-2.. And the obvious consequence of the lack of evidence of its isolation is that such coronaviruses cannot be held responsible for any disease. Moreover, all tests - of whatever kind - based on the presumed components of these viruses ...
In an accompanying editorial, Kenneth McIntosh of Harvard University commented that discovery of a new human respiratory coronavirus would not be surprising, since studies in the 1960s and 1970s had pointed to a number of novel coronavirus strains but the findings were not adequately followed up because methods to do so were unavailable at the time. The statistically strong association with Kawasaki disease, however, was quite surprising. Noting that previous attempts to link Kawasaki disease to bacteria or other viruses had failed and thus justified healthy skepticism about the present findings, Dr. McIntosh pointed out some tantalizing facts: onset of Kawasaki disease is often preceded by a respiratory syndrome; both the disease and respiratory coronavirus infections are seasonal, peaking in the winter and spring; recent studies have described a powerful immune response in the respiratory tract and other organs in acute cases of Kawasaki disease, suggesting the involvement of a specific ...
Since the first cases of coronavirus were reported in December 2019 in Wuhan, China, the scientific community has been searching for an effective treatment, relying largely on prior knowledge about the other 6 known human coronaviruses to date, of which, the SARS-CoV and the MERS-CoV were responsible for major epidemics in 2003 and 2012 respectively.. It was precisely in 2003 when Savarino et al. hypothesized the possible usefulness of chloroquine and hydroxychloroquine in the treatment of SARS-CoV,1 prompting several studies in subsequent years trying to evaluate its in vitro antiviral efficacy against this and other human coronaviruses, collected in a review recently published by Raoult et al.2. The different investigations carried out since then attribute to these 2 drugs an antiviral action dependent on multiple mechanisms, sometimes replicated in in vivo studies, and that, in the case of COVID-19, could include interference with glycosylation of the ACE2 receptor that the virus uses to bind ...

AU - Katzea, Michael G.. PY - 2013. Y1 - 2013. N2 - A novel human coronavirus (HCoV-EMC) was recently identified in the Middle East as the causative agent of a severe acute respiratory syndrome (SARS) resembling the illness caused by SARS coronavirus (SARS-CoV). Although derived from the CoV family, the two viruses are genetically distinct and do not use the same receptor. Here, we investigated whether HCoV-EMC and SARS-CoV induce similar or distinct host responses after infection of a human lung epithelial cell line. HCoV-EMC was able to replicate as efficiently as SARS-CoV in Calu-3 cells and similarly induced minimal ...
In a fight against the novel coronavirus, scientists have found that certain oral antiseptics and mouthwashes may have the ability to inactivate human
Using the purified proteins as antigens in ELISA assays for antibodies in the sera of SARS patients we found that the assay using truncated S-N fusion protein has a clearly higher sensitivity than those using intact N protein or truncated S and N proteins, and virtually as high as the assay using whole SARSCoV lysate (Table 2). The results indicated the N and S protein were complementary in detecting SARS-specific antibodies. This is consistent with previous studies [28, 29]. Five positive sera to SARSCoV lysate antigen were all tested positive against SARSCoV N protein but negative against SARSCoV truncated N-S protein. These sera were also tested positive against N proteins of HCoV 229E and HCoV OC43 (data not shown), which could be reasonably explained partly by existence of other HCoV infections in these humans. The truncated S-N fusion protein was also subjected to ELISA with mice antisera against SARSCoV (BJ01), HCoV 229E and HCoV OC43. Only mice antiserum against SARSCoV(BJ01) tests ...

Although a number of pharma firms are speeding to provide a vaccine for the coronavirus causing the COVID-19 pandemic, aided by expedited regulatory processes, questions still remain over how nations will ensure widespread entry to the inoculation. The recent coronavirus outbreak sparked a 2020 review printed in the Journal of Hospital Infection , which pantozol checked out other coronaviruses (together with SARS, MERS, and other endemic human coronaviruses), and decided that they will live on surfaces like metallic, glass, or plastic for anywhere from two hours to nine days. Wherever doable it is preferable for customers to acquire their prescription medicines at a standard pharmacy, significantly when the prescription pantozol is for a new drug or for a critical condition. In bigger amenities and offices, a psychiatrist might think about prescription administration and leave the talk remedy to different psychological health suppliers. pantozolIs a PPI considered an antacid?

The ongoing outbreak of the novel human coronavirus SARS-CoV-2 (also known as 2019-nCoV) has become a global health concern. Rapid and ease-to-use diagnostic techniques are urgently needed to diagnose SARS-CoV-2 infection.We devised a reverse transcription multiple cross displacement amplification (RT-MCDA) coupled with nanoparticles-based biosensor (BS) assay (RT-MCDA-BS) for rapid, sensitive and specific diagnosis of COVID-19. Two primer sets were designed to target the open reading frame 1a/b (F1ab) and nucleoprotein gene (N) of SARS-CoV-2. A total of 183 clinical samples, including 65 patients with COVID-19 infections and 118 patients with other pathogen infections, were used to testify the assays feasibility. The diagnosis results were visually reported using BS.The designed assay was performed using a simple instrument which could maintain the reaction in a constant temperature at 64°C for only 35 min. The total procedure of COVID-19 RT-MCDA-BS test could be finished within 1 h. The ...
The emergence of a new coronavirus in Wuhan China has triggered a global need for accurate diagnostic assays. Initially, mostly laboratory developed molecular tests were available but shortly thereafter different commercial assays started to appear and are still increasing in number. Although independent performance evaluations are ongoing, available data is still scarce. Here we provide a direct comparison of key performance characteristics of 13 commercial RT-PCR assays. Thirteen RT-PCR assays were selected based on the criteria that they can be used following generic RNA extraction protocols, on common PCR platforms and availability. Using a 10-fold and 2-fold dilution series of a quantified SARS-CoV-2 cell-cultured virus stock, performance was assessed compared to our in house validated assay. Specificity was tested by using RNA extracted from cultured common human coronaviruses. All RT-PCR kits included in this study exhibited PCR efficiencies , 90%, except for the Sentinel Diagnostics B ...
DECLARE: The novel coronavirus can stay on surfaces for days. Stay home as a lot as attainable, and keep away from close contact with different folks, even individuals you reside with.

Healthy children in the ORChID community-based birth cohort experienced an incidence rate of 978 new VDEs per 100 child-years during the first 2 years of life, with HRV playing a dominant role. Overall, respiratory viruses were detected by PCR in regular weekly swabs at least once during 75% of ARIs, while in asymptomatic periods 23% of weekly nasal swabs were positive by PCR for respiratory viruses, accounting for 33% of all new VDEs. We demonstrated evidence of attribution for ARIs by RNA viruses, which included HRV (HRV-A, HRV-C), influenza (IFV-A), parainfluenza (PIV-1, PIV-3), RSV (RSV-A, RSV-B), HCoV (HCoV-OC43, HCoV-NL63) and HMPV; and AdV as the single DNA virus representative. All these viruses were detected significantly more often in children with an ARI than during asymptomatic periods and had statistically significant positive AFEs. The largest association was observed for RSV and HMPV, both of which were more strongly associated with LRTIs than other respiratory viruses. Increasing ...
Seven coronaviruses have been recognised to cause human disease. HCoV-OC43, HCoV-NE63, HCoV-HKU1, and HCoV-229E are known as common cold coronaviruses1,2.
A new report suggests that lingering brain fog and other neurological symptoms after COVID -19 recovery may be due to post-traumatic stress disorder (PTSD), an effect observed in past human coronavirus outbreaks such as SARS and MERS.
