The epidemiology of enteroviral infection in South Korea during 1999-2011 chronicles nationwide outbreaks and changing detection and subtyping methods used over the 13-year period. Of 14,657 patients whose samples were tested, 4,762 (32.5%) samples were positive for human enterovirus (human EV); as diagnostic methods improved, the rate of positive results increased. A seasonal trend of outbreaks was documented. Genotypes enterovirus 71, echovirus 30, coxsackievirus B5, enterovirus 6, and coxsackievirus B2 were the most common genotypes identified. Accurate test results correlated clinical syndromes to enterovirus genotypes: aseptic meningitis to echovirus 30, enterovirus 6, and coxsackievirus B5; hand, foot and mouth disease to coxsackievirus A16; and hand, foot and mouth disease with neurologic complications to enterovirus 71. There are currently no treatments specific to human EV infections; surveillance of enterovirus infections such as this study provides may assist with evaluating the need to
The use of the neutralisation assay in the serotyping of unknown enterovirus isolates has been successfully applied for years since its description by Lim and Benyesh-Melnick. However, the procedure is labour-intensive and time consuming. In addition, the continuous depletion of the Benyesh-Melnick sera makes it prohibitive for most diagnostic laboratories to continue using the assay. Owing to these factors, a majority of laboratories only type for the polioviruses and report any other enterovirus isolate as a nonpolio enterovirus. With this approach, however, important findings such as the isolation of a new enterovirus or association of a known enterovirus with a new clinical syndrome will remain unidentified. <br>In this study, a multiple-serum-pools approach similar to that described by Lim and Benyesh-Melnick (LBM) for the neutralisation test, was applied in an immunofluorescence (IMF) test for the rapid serotyping of enteroviruses. This test was able to type any unknown enterovirus

Enterovirus (EV-D68 and EV71) symptoms include runny nose, fever, cough, and sneezing. Get the facts on treatment and prevention of non-polio enteroviruses.
How it spreads. The virus is contagious and spreads through direct contact with saliva, mucus and even fecal matter from infected people. Quite often there are small epidemics of this virus in kindergartens and schools. Skin rash usually disappears by itself after a week, and in most cases need no treatment except symptomatic like paracetamol against fever. There are no vaccines however, infected persons are most contagious during the first week, and the possibility of transmission of virus persists for another few weeks. Can you get Coxsackie virus more than once. Yes, infection only results in the emergence of immunity to one specific type, but the Coxsackie virus, as mentioned above, is divided into three types. How to protect yourself from infection. One of the main and most effective methods of prevention of infection with Coxsackie virus is the observance of strict rules of hygiene. First and foremost, you must frequently wash their hands with soap and water especially after touching ...
Human enteroviruses (EVs) are the most common causative agents infecting human, causing many harmful diseases, such as hand, foot, and mouth disease (HFMD), herpangina (HA), myocarditis, encephalitis, and aseptic meningitis. EV-related diseases pose a serious worldwide threat to public health. To gain comprehensive insight into the seroepidemiology of major prevalent EVs in humans, we firstly performed a serological survey for neutralizing antibodies (nAbs) against Enterovirus A71 (EV-A71), Coxsackie virus A16 (CV-A16), Coxsackie virus A6 (CV-A6), Coxsackie virus A10 (CV-A10), Coxsackie virus B3 (CV-B3), Coxsackie virus B5 (CV-B5), Echovirus 25 (ECHO25), and Echovirus 30 (ECHO30) among the healthy population in Xiamen City in 2016, using micro-neutralization assay ...
RESULTS: Of the 308 samples processed, 17 (5.5%) grew on both L20B and RD cells while 32 (10.4%) grew on RD only. All 28 isolates from L20B were characterized by rRT-PCR as Sabin-like polioviruses. No wild poliovirus or VDPV was found. However from the microneutralisation assay, six different enteroviruses were characterized. Among these, Coxsackie B viruses were most predominant followed by Echovirus. Three children from whom non-polio enteroviruses were isolated had residual paralysis while one child with VAPP found. The non-polio enteroviruses circulated throughout the country with the majority (20.7%) from Ashanti region.. Conclusions: This study showed the absence of wild or vaccine-derived poliovirus circulation in the country. However, the detection of three non-polio enteroviruses and one Sabin-like poliovirus with residual paralysis call for continuous surveillance even in the post polio eradication era.. Outcome of Research: Not applicable. Availability of Paper: The full text of this ...
Enterovirus 68 (EV68, EV-D68 or HEV68) is a type of enterovirus (see Enterovirus) that can cause mild to severe respiratory illness. Enteroviruses as a group are fairly common illnesses however EV68 is uncommon. Enterovirus-68 infections are difficult to track, because its symptoms are like the symptoms of the common cold and other illnesses. Many hospitals and clinics do not test for specific types of enteroviruses. Common symptoms include fever, runny nose, sneezing, cough, and body/muscle aches. However, more severe infections may cause difficulty in breathing and even respiratory failure. Infants and children under the age of 5 are at the highest risk for serious infections, but older children and teenagers may also be at risk, because they have not yet developed immunity (protection from) to many viruses. Children with asthma seem to have a higher risk for respiratory problems with this virus and may need to be hospitalized. The virus can be spread through saliva, sneezing, or touching ...
Enteroviruses cause a range of human and animal diseases, some life-threatening, but there remain no licenced anti-enterovirus drugs. However, a benzene-sulfonamide derivative and related compounds have been shown recently to block infection of a range of enteroviruses by binding the capsid at a positively-charged surface depression conserved across many enteroviruses. It has also been established that glutathione is essential for the assembly of many enteroviruses, interacting with the capsid proteins to facilitate the formation of the pentameric assembly intermediate, although the mechanism is unknown. Here we show, by high resolution structure analyses of enterovirus F3, that reduced glutathione binds to the same interprotomer pocket as the benzene-sulfonamide derivative. Bound glutathione makes strong interactions with adjacent protomers, thereby explaining the underlying biological role of this druggable binding pocket and delineating the pharmacophore for potential antivirals.
BACKGROUND AND OBJECTIVES: The infrastructure established for screening blood donations for hepatitis C virus has enabled large-scale population testing for other viruses which are potentially transmissible by transfusion of blood components and plasma-derived blood products. We have measured the frequency of viraemia of enteroviruses and parechoviruses in 83 600 Scottish blood donors to allow an initial assessment of their risk to blood safety. MATERIALS AND METHODS: Plasma samples collected from blood donors over 7 calendar months were tested anonymously in mini-pools of 95 donations, by polymerase chain reaction (PCR) for human enterovirus and parechovirus sequences. RESULTS: A total of 19 mini-pools, from the 880 that were tested, were PCR-positive for enterovirus RNA, predicting a donor prevalence of 0.023%. Enterovirus sequences were not detected in factor VIII or IX clotting factor concentrates. None of the 230 mini-pools or concentrates contained detectable parechovirus RNA. CONCLUSIONS: The
The aim of this project is to study the particular characteristics and to unravel the molecular mechanism of action of novel inhibitors of the replication of picornaviruses (genus enterovirus) that have recently been discovered in our laboratory. The development of inhibitors of enterovirus replication is of utmost importance. Despite intensive vaccination campaigns, the poliovirus is still not eradicated. It is now widely accepted that antivirals will be needed to aid in the late stages of the polio endgame and in the post-polio era. Besides polio, many other enteroviruses cause a wide spectrum of diseases in man (aseptic meningitis; viral myocarditis, respiratory tract infections); there is no vaccine nor specific therapy available.

Conventional culture detected 74 enterovirus isolates. Oberste, M., Schnurr, D., Maher, K., al-Busaidy, S. We prospectively studied children with suspected HEV-71 (i.e., hand-foot-and-mouth disease, CNS disease, or both) over 3.5 years, using detailed virological investigation and genogroup analysis of all isolates. To increase yield and enhance the rapidity of enterovirus isolation in cell cultures, we used Buffalo green monkey kidney (BGM) cells and subpassages of primary human embryonic kidney (HEK) cells in addition to the human diploid fibroblast (MRC-5) cells and primary cynomolgus or rhesus monkey kidney (MK) cells routinely used for enterovirus culturing. A series of unrelated viral isolates as well as CSF samples from patients with meningitis/encephalitis or neurological syndromes unrelated to enterovirus infection were included as controls.

With an increase in viral illness being reported locally, and clusters of enterovirus EV-D68 growing across WV, Princeton Health Care is protecting its residents of the long-term care facility by limiting visitors to only those who are healthy.. Princeton Health Care Centers physician and infection control preventionist have carefully reviewed recommendations from the Centers for Disease Control. After this careful consideration, the decision has been made to limit visitors to only those who are healthy until further notice.. We are seeing an increase in respiratory illness in the region. Implementing our visitor limitations helps to protect our residents who may already be facing medical challenges.. Enteroviruses are very common viruses; there are more than 100 types. Most people infected with enteroviruses have no symptoms or only mild symptoms, but some infections can be serious. Infants, children and teenagers are most likely to get infected with enteroviruses and become sick. Most ...
Enterovirus: This group includes enteroviruses, which attack the vertebrate intestinal tract and often invade the central nervous system as well; rhinoviruses, which infect the tissues in the vertebrate nose; and the virus agent of foot-and-mouth disease. Among the enteroviruses are polioviruses, echoviruses (enteric, cytopathogenic, human, orphan), and Coxsackie viruses.
Enterovirus 71 is one of the viruses that causes hand-foot-and-mouth disease in children. It is an enterovirus, one of the picornaviruses. Infection with enterovirus 71 predominantly results in a vesicular rash of the hands and feet that follows...
We describe an improvement of an earlier reported real-time RT-PCR assay for the detection of enterovirus RNA, based on the 5 exonuclease digestion of a dual-labeled fluorogenic probe by Taq DNA polymerase. A different extraction method, real-time RT-PCR instrument and primer set were evaluated. Our data show that the optimized assay yields a higher sensitivity and reproducibility and resulted in a significant reduced hands-on time per sample.

|h4|Background|/h4|Diseases caused by human enteroviruses (EVs) are a major global public health problem. Thus, the effective diagnosis of all human EVs infections and the monitoring of epidemiological and ecological dynamic changes are urgently needed.|h4|Methods|/h4|Based on two comprehensive virological surveillance systems of hand, foot and mouth disease (HFMD), real-time PCR and nested RT-PCR (RT-snPCR) methods based on the enteroviral VP1, VP4-VP2 and VP4 regions were designed to directly detect all human EVs serotypes in clinical specimens.|h4|Results|/h4|The results showed that the proposed serotyping strategy exhibit very high diagnostic efficiency (Study 1: 99.9%; Study 2: 89.5%), and the variance between the study was due to inclusion of the specific Coxsackie virus A6 (CVA6) real-time RT-PCR and VP4 RT-snPCR in Study 1 but not Study 2. Furthermore, only throat swabs were collected and analyzed in Study 2, whereas in Study 1, if a specific EV serotype was not identified in the primary stool
In the past 2 years, CDC has learned of several clusters of respiratory illness associated with human enterovirus 68 (HEV68), including severe disease. HEV68 is a unique enterovirus that shares epidemiologic and biologic features with human rhinoviruses (HRV) (1). First isolated in California in 1962 from four children with bronchiolitis and pneumonia (2), HEV68 has been reported rarely since that time and the full spectrum of illness that it can cause is unknown. The six clusters of respiratory illness associated with HEV68 described in this report occurred in Asia, Europe, and the United States during 2008--2010. HEV68 infection was associated with respiratory illness ranging from relatively mild illness that did not require hospitalization to severe illness requiring intensive care and mechanical ventilation. Three cases, two in the Philippines and one in Japan, were fatal. In these six clusters, HEV68 disproportionately occurred among children. CDC learned of clusters of HEV68 from public ...
To develop a real-time diagnostic technique with Virosensor for Enterovirus 71 and Influenza Virus detection, the investigators conduct a prospective clinical study. In comparison with results from direct sequencing of Enterovirus 71 and Influenza Virus, the investigators evaluate the performance of virosensor , including reproducibility, sensitivity, specificity, and cross-reaction. The potential factors which may interfere with the results would be investigated. With such technique, the investigators hope to make early diagnosis and give Enterovirus 71 and Influenza Virus patients early treatment to reduce the complications and case-fatality rate ...

Enterovirus A71 (EV-A71) is one of more than 100 non-polio enteroviruses. Learn how common it is, its symptoms and spread, and more.
At least three different EV-71 subgenotypes were identified from an outbreak in Malaysia in 1998. The subgenotypes C2 and B4 were associated with the severe and fatal infections, whereas the B3 virus was associated with mild to subclinical infections. The B3 virus genome sequences had ≥85% similarity at the 3 end to CV-A16. This offers opportunities to examine if there are characteristic similarities and differences in virulence between CV-A16, EV-71 B3 and EV-71 B4 and to determine if the presence of the CV-A16-liked genes in EV-71 B3 would also confer the virus with a CV-A16-liked neurovirulence in mice model infection. Analysis of human enterovirus 71 (EV-71) subgenotype B3 genome sequences revealed that the 3D RNA polymerase and domain Z of the 3-untranslating region RNA secondary structure had high similarity to CV-A16. Intracerebral inoculation of one-day old mice with the virus resulted in 16% of the mice showing swollen hind limbs and significantly lower weight gain in comparison to EV-71 B4
PEREZ, Ana C. et al. Hepatitis and coagulopathy secondary to neonatal enteroviral infection. Arch. argent. pediatr. [online]. 2009, vol.107, n.6, pp.550-553. ISSN 0325-0075.. Enteroviruses cause a wide spectrum of clinical manifestations in neonates, from asymptomatic infection to severe and fulminant, sometimes fatal disease. A septic disease is the clinical manifestation of one fourth of the cases in neonates, with multiorganic affection. Hepatitis and coagulopathy are related to bad prognosis, generally associated to catastrophic hemorrhages. In those cases, an aggressive support therapy and correct administration of platelet and clotting factor replacement is necessary. The liver, in survivors, frequently has sufficient regenerative capacity to allow normalization of hepatic function and adequate growth of the child. We present the case of a newborn who developed hepatitis and coagulopathy secondary to an enteroviral infection, with total recovery and absence of hemorrhagic complication. Her ...
We have previously reported that RAS-MEK (Cancer Res. 2003 May 1;63(9):2088-95) and TGF-β (Cancer Res. 2006 Feb 1;66(3):1648-57) signaling negatively regulate coxsackie virus and adenovirus receptor (CAR) cell-surface expression and adenovirus uptake. In the case of TGF-β, down-regulation of CAR occurred in context of epithelial-to-mesenchymal transition (EMT), a process associated with transcriptional repression of E-cadherin by, for instance, the E2 box-binding factors Snail, Slug, SIP1 or ZEB1. While EMT is crucial in embryonic development, it has been proposed to contribute to the formation of invasive and metastatic carcinomas by reducing cell-cell contacts and increasing cell migration.. ...

What is the best way to clean surfaces?. The best way to clean surfaces is to use a bleach-based household cleaner as directed on the product label. If no such cleaning product is available, you can use a solution made with 5 tablespoons to 1.5 cups of household bleach per 1 gallon of water. If you are unable to use bleach, look for cleaning products that list Alkyl dimethyl benzyl ammonium chloride as an active ingredient on the label and says that the product kills norovirus and rhinovirus. This includes products such as Lysol All-purpose cleaner, Pine-Sol All-purpose cleaner and Clorox disinfecting spray/wipes. Follow instructions on the label. Enteroviruses are resistant to alcohol disinfection. The Environmental Protection Agency (EPA) website has a list of commercial cleaning products for noroviruses; these also kill enteroviruses: EPA-Registered Disinfectants ...

Most patients with type 1 diabetes are considered to have a T-cell mediated autoimmune disease. The chemokine CXCL10 promotes the migration of activated T-cells. Virus infections might contribute to the pathogenesis of type 1 diabetes and enterovirus protein and/or genome have been detected in beta-cells from a majority of tested newly diagnosed children with type 1 diabetes. The chemokine CXCL10 is induced in human islet cells by enterovirus infections in vivo and in vitro, but is not expressed in islets from normal organ donors. Since CXCL10 is a chemokine known to be induced by virus infections and/or cellular damage, our aim was to study if levels of CXCL10 are elevated in serum from children with type 1 diabetes and whether it correlates to the presence of enterovirus markers. CXCL10, neutralizing antibody titer rises against certain enterovirus, and antibodies against GAD65 were measured in serum, and enterovirus PCR was performed on whole blood from 83 type 1 diabetes patients at onset, ...
Doctors at Advocate Sherman Hospital say Kane County parents should be aware but not unduly concerned about reports that children in Colorado who have tested positive for enterovirus D68 (EV-D68) recently were diagnosed with neurological symptoms that include limb weakness and temporary paralysis.. According to a report in Sherman Hospitals excellent e-news page the Centers for Disease Control and Prevention reports that nine children were diagnosed with temporary paralysis. Four of those children tested positive for EV-D68, with another two children reportedly having another enterovirus or rhinovirus strain.. Dr. James Malow, infectious disease specialist at Advocate Illinois Masonic Medical Center, agrees that these reports are no reason for undue concern among parents at this time, but parents should be aware of the situation.. This is something that needs to be investigated fully. We need to see what develops, he says. Thats why the CDC is contacting state and local health officials - ...
According to the Centers for Disease Control & Prevention (CDC), infants, children, and teenagers are most likely to get infected with enteroviruses and become ill, because they do not yet have immunity (protection) from previous exposures to these viruses. Adults can get infected with enteroviruses, but they are more likely to have no symptoms or mild symptoms. Children with asthma may have a higher risk for severe respiratory illness caused by EV-D68 infection.. Other Frequently Asked Questions ...
There are many types of enteroviruses. The viruses mostly cause illness in babies, children, and teens. This is because most adults have already had enteroviruses and have built up immunity.
Current or recent enteroviral infections show an association with type 1 diabetes. However, evidence for this has mainly been generated using a particular mouse monoclonal antibody (clone 5-D8/1) which binds the viral capsid protein VP1. Difficulty in confirming these findings using other independent methods has led to the concern that this might be artefactual. To address this, we examined the potential cross-reactivity of clone 5-D8/1 with normal islet proteins. Western blotting, two-dimensional gel electrophoresis, and mass spectrometry were used to identify human islet proteins bound by the clone 5-D8/1. We found a distinct reactivity with two mitochondrial proteins, creatine kinase B-type and ATP synthase beta subunit. Immunohistochemistry using the clone 5-D8/1 revealed a granular cytoplasmic staining pattern in mitochondria-rich cells, ie hepatocytes, ductal epithelial cells, vascular endothelial cells, skeletal muscle cells, and the neoplastic salivary gland oncocytoma cells, whereas ...
Enterovirus 71 (EV71) and Coxsackievirus A16 (CA16) are two major etiological agents of Hand, Foot and Mouth Disease (HFMD). EV71 is associated with severe cases but not CA16. The mechanisms contributed to the different pathogenesis of these two viruses are unknown. VP1 and VP4 are two major structural proteins of these viruses, and should be paid close attention to. The sequences of vp1s from 14 EV71 and 14 CA16, and vp4s from 10 EV71 and 1 CA16 isolated in this study during 2007 to 2009 HFMD seasons were analyzed together with the corresponding sequences available in GenBank using DNAStar and MEGA 4.0. Phylogenetic analysis of complete vp1s or vp4s showed that EV71 isolated in Beijing belonged to C4 and CA16 belonged to lineage B2 (lineage C). VP1s and VP4s from 4 strains of viruses expressed in E. coli BL21 cells were used to detect IgM and IgG in human sera by Western Blot. The detection of IgM against VP1s of EV71 and CA16 showed consistent results with current infection, while none of the sera
Enteroviruses can be found in the respiratory secretions (e.g., saliva, sputum, or nasal mucus) and stool of an infected person. Other persons may become infected by direct contact with secretions or stool from an infected person or by contact with contaminated surfaces or objects, such as a drinking glass or telephone. Parents, teachers, and child care center workers may also become infected by contamination of the hands with stool from an infected infant or toddler during diaper changes.. ...

Human enteroviruses and human parechoviruses are associated with a broad range of diseases and even severe and fatal conditions. For human cosaviruses, the etiological role is yet unknown. Little is known about the circulation of non-polio enteroviruses, human parechoviruses, and human cosaviruses in Nigeria. A total of 113 stool samples were collected from healthy individuals in Osun State between February 2016 and May 2017. RT-PCR assays targeting the 5′ non-coding region (5′ -NCR) were used to screen for human enteroviruses, human parechoviruses, and human cosaviruses. For human enteroviruses, species-specific RT-PCR assays targeting the VP1 regions were used for molecular typing. Inoculation was carried out on RD-A, CaCo-2, HEp-2C, and L20B cell lines to compare molecular and virological assays. Ten samples tested positive for enterovirus RNA with 11 strains detected, including CV-A13 (n = 3), E-18 (n = 2), CV-A20 (n = 1), CV-A24 (n = 1), EV-C99 (n = 1), and EV-C116 (n = 2). Three ...
TY - JOUR. T1 - Enteroviruses. AU - Muir, Peter. N1 - Copyright: Copyright 2010 Elsevier B.V., All rights reserved.. PY - 2009/12. Y1 - 2009/12. N2 - The human enteroviruses are ubiquitous small non-enveloped RNA viruses that are important causes of aseptic meningitis, myocarditis, hand, foot and mouth disease, acute haemorrhagic conjunctivitis, herpangina, and Bornholm disease (pleurodynia), as well as non-specific febrile and respiratory illnesses, and rash. They include the coxsackieviruses, echoviruses and polioviruses. The polioviruses cause paralytic poliomyelitis, which has almost been eliminated through the use of live and inactivated poliovirus vaccine. Neonatal enterovirus infection can be particularly severe. Laboratory diagnosis of enterovirus infections has been greatly improved in recent years by replacing viral culture and serology with enterovirus-specific polymerase chain reaction; this is now part of routine cerebrospinal fluid investigations. Although specific antiviral ...

The efficacy of germicidal ultraviolet (UV-C) light emitting diodes (LEDs) was evaluated for inactivating human enteroviruses included on the United States Environmental Protection Agency (EPA)s Contaminant Candidate List (CCL). A UV-C LED device, emitting at peaks of 260 nm and 280 nm and the combination of 260/280 nm together, was used to measure and compare potential synergistic effects of dual wavelengths for disinfecting viral organisms. The 260 nm LED proved to be the most effective at inactivating the CCL enteroviruses tested. To obtain 2-log10 inactivation credit for the 260 nm LED, the fluences (UV doses) required are approximately 8 mJ/cm2 for coxsackievirus A10 and poliovirus 1, 10 mJ/cm2 for enterovirus 70, and 13 mJ/cm2 for echovirus 30. No synergistic effect was detected when evaluating the log inactivation of enteroviruses irradiated by the dual-wavelength UV-C LEDs.. ...
Coxsackievirus is a virus that belongs to a family of nonenveloped, linear, positive-sense single-stranded RNA viruses, Picornaviridae and the genus Enterovirus, which also includes poliovirus and echovirus. Enteroviruses are among the most common and important human pathogens, and ordinarily its members are transmitted by the fecal-oral route. Coxsackieviruses share many characteristics with poliovirus. With control of poliovirus infections in much of the world, more attention has been focused on understanding the nonpolio enteroviruses such as coxsackievirus. Coxsackieviruses are among the leading causes of aseptic meningitis (the other usual suspects being echovirus and mumps virus). The entry of coxsackievirus into cells, especially endothelial cells, is mediated by Coxsackie virus and adenovirus receptor. Coxsackieviruses are divided into group A and group B viruses based on early observations of their pathogenicity in neonatal mice. Group A coxsackieviruses were noted to cause a flaccid ...
Using Chinas national surveillance data on hand, foot and mouth disease (HFMD) for 2008-2015, we described the epidemiologic and virologic features of recurrent HFMD. A total of 398,010 patients had HFMD recurrence; 1,767 patients had 1,814 cases of recurrent laboratory-confirmed HFMD: 99 reinfections of enterovirus A71 (EV-A71) with EV-A71, 45 of coxsackievirus A16 (CV-A16) with CV-A16, 364 of other enteroviruses with other enteroviruses, 383 of EV-A71 with CV-A16 and CV-A16 with EV-A71, and 923 of EV-A71 or CV-A16 with other enteroviruses and other enteroviruses with EV-A71 or CV-A16. The probability of HFMD recurrence was 1.9% at 12 months, 3.3% at 24 months, 3.9% at 36 months, and 4.0% at 38.8 months after the primary episode. HFMD severity was not associated with recurrent episodes or time interval between episodes. Elucidation of the mechanism underlying HFMD recurrence with the same enterovirus serotype and confirmation that HFMD recurrence is not associated with disease severity is needed.
BACKGROUND: Enteroviruses are non-enveloped, frequently pathogenic RNA viruses infecting humans. Infection is potentially transmissible through blood or blood component transfusion from donor in the viremic phase before seroconversion for antibody. To investigate the threat to blood safety from enteroviruses, a large-scale survey of frequency and levels of viremia in blood donors was conducted. STUDY DESIGNS AND METHODS: Blood donations from Scotland over a period of 22 calendar months were screened for enterovirus RNA sequences by PCR. Positive samples were quantified, and serotypes were identified by nucleotide sequencing of VP1. RESULTS: From a total of 3658 pools of 95 donations tested, 73 samples that were enterovirus-positive were identified (corrected annual frequency 0.024% or 1 in 4000). The highest rates of viremia were in late summer months (e.g., 0.055%, 1 in 1800 in July) and lowest from January to May (0.009 and 0.012%). Viral loads ranged from 500 (the lower cutoff of the assay) to
Enteroviruses (EVs) are viruses of the family Picornaviridae that cause mild to severe infections in humans and in several animal species, including non-human primates (NHPs). We conducted a survey and characterization of enteroviruses circulating between humans and great apes in the Congo. Fecal samples (N = 24) of gorillas and chimpanzees living close to or distant from humans in three Congolese parks were collected, as well as from healthy humans (N = 38) living around and within these parks. Enteroviruses were detected in 29.4% of gorilla and 13.15% of human feces, including wild and human-habituated gorillas, local humans and eco-guards. Two identical strains were isolated from two humans coming from two remote regions. Their genomes were similar and all genes showed their close similarity to coxsackieviruses, except for the 3C, 3D and 5-UTR regions, where they were most similar to poliovirus 1 and 2, suggesting recombination. Recombination events were found between these strains, poliovirus 1 and

Virus isolation in cell cultures has been the standard method for enterovirus 71 identification in Clinical Virology Laboratories. However, virus isolation takes 5-10 days when using cell culture. A microchip for enterovirus 71 detection was developed as an alternative diagnostic method. The novel approach is based on hybridization of amplified DNA specimens with oligonucleotide DNA probes immobilized on a microchip. Two oligonucletides were used as detection ...
Enteroviruses (EVs) species A are a major public health issue in the Asia-Pacific region and cause frequent epidemics of hand, foot and mouth disease (HFMD) in China. Mild infections are common in children; however, HFMD can also cause severe illness that affects the central nervous system. To molecularly characterize EVs, a prospective HFMD virological surveillance program was performed in China between 2013 and 2016. Throat swabs, rectal swabs and stool samples were collected from suspected HFMD patients at participating hospitals. EVs were detected using generic real-time and nested reverse transcription-polymerase chain reactions (RT-PCRs). Then, the complete VP1 regions of enterovirus A71 (EV-A71), coxsackievirus A16 (CVA16) and CVA6 were sequenced to analyze amino acid changes and construct a viral molecular phylogeny. Of the 2836 enrolled HFMD patients, 2,517 (89%) were EV positive. The most frequently detected EVs were CVA16 (32.5%, 819), CVA6 (31.2%, 785), and EV-A71 (20.4%, 514). The
Picornaviruses represent a very large virus family with respect to the number of members but one of the smallest in terms of virion size and genetic complexity. They include two major groups of human pathogens: enteroviruses and rhinoviruses. Enteroviruses are transient inhabitants of the human alimentary tract and may be isolated from the throat or lower intestine. Rhinoviruses are associated with the respiratory tract and isolated chiefly from the nose and throat. Less -common picornaviruses associated with human illness include hepatitis A virus, parechovirus, cardiovirus, and Aichi virus. Several genera of picornaviruses are also associated with -animal, plant, and insect disease. ...

We have performed immunostructural analyses of three closely related picornaviruses in order to gain understanding of the biochemical and structural basis of serotype specificity. We carried out sequence alignments of the capsid regions of three bovine enterovirus strains: VG-5-27 and M-4 from serotype 1 and PS-87 from serotype 2. Using our knowledge of the three dimensional and antigenic structure of strain VG-5-27 and the high levels of sequence identity between the strains, we have calculated the structures and solvent-accessible electrostatic potentials of the epitopes of all three viruses. We have demonstrated the viability of the molecular models of the epitopes of the M-4 and PS-87 strains. In each of the strains, we have explained the serotype specificities in terms of specific physical and chemical properties, and identified individual residues which are pivotal in determination of antibody recognition. These changes are in agreement with the known cross-reactivity of peptide and ...

One leading candidate is enterovirus D68, which has caused outbreaks of respiratory disease in North America, but surveillance data on this virus is sparse.. Here, Park et al. modeled the epidemiology of enterovirus D68 in the U.S. with data from the BioFire Syndromic Trends repository and compared nationwide enterovirus D68 prevalence to the actual incidence of reported AFM cases. Using a powerful algorithm, the team observed a strong correlation between enterovirus D68 and AFM: they predicted that enterovirus D68 peaked roughly every two years, with the peaks occurring directly before AFM epidemics in the autumn.. The researchers also predicted that moderate or large outbreaks of enterovirus D68 would have occurred under normal conditions in 2020, but that mask-wearing and other measures reduced the risk of outbreaks and likely contributed to the observed decline in cases of AFM..

Objective: The study aims to understand the characteristics and epidemic trend of the pathogen of hand, foot and mouth disease (HFMD) in Guangxi regions, China. Besides, it aims to analyze the differences of intestinal virus detection rate between anal swab and pharyngeal swab samples. Methods: Anal swab and pharyngeal swabs of suspected HFMD children were collected in our hospital from 2012 to 2015. Real-time fluorescent PCR (Polymerase Chain Reaction) was used to detect enterovirus 71 (EV71), coxsackie virus type 16 (CA16), and universal intestinal virus nucleic acid (EV). Composition and conversion of predominant pathogens were analyzed, and paired samples test results of swabs anal and pharyngeal swab were statistically analyzed. Results: There are 681 cases with enterovirus in 2351 cases of patients. Among those who got enterovirus, there are 501 cases of EV71, 102 cases of CA16 and 79 cases of EV. From 2012 to 2015, the total proportion of the virus detection is 46.47%, 16.23%, 41.02% and 15.33%

Receptor binding and subsequent cell-mediated internalization or disassembly are the initial steps in virus replication. Cell surface molecules that participate in this process are the primary determinants of virus tissue tropism. Monoclonal antibody blockade, immunoprecipitation, and DNA transfection were used to identify decay accelerating factor as a major cell attachment receptor for coxsackieviruses B1, B3, and B5. However, expression of human decay acceleration factor on the surface of nonpermissive murine fibroblasts led only to virus attachment without subsequent replication, and it was concluded that an additional cellular cofactor(s) is required to facilitate cell entry and subsequent replication.
The Enterovirus genus within the family Picornaviridae contains over 100 serotypes, of which sixty-four are known to be human pathogens. Infection with this group of RNA viruses produces a myriad of clinical conditions including poliomyelitis, meningitis, encephalitis, respiratory illnesses, and hand-foot-and-mouth disease. Outbreaks have been documented worldwide; significant morbidity and mortality exist to warrant laboratory surveillance. Traditionally, enteroviruses have been identified to the level of serotype by the serum neutralization assay. However, numerous problems are associated with this assay. The serum neutralization assay is labor intensive, results are often ambiguous, and reagents are becoming difficult to obtain. Recently, molecular-based typing protocols have been described that are cost effective and produce results that are more reliable. The overall objective of this thesis was to implement a molecular-based typing protocol to replace the serum neutralization method currently used
BACKGROUND: Enterovirus (EV) meningitis is common in infants and may have neurologic complications. Treatment of older children and adults with pleconaril has been associated with reduced severity and duration of symptoms. This study evaluated the pharmacokinetics, safety and efficacy of pleconaril in infants with EV meningitis. METHODS: Infants < or =12 months old with suspected EV meningitis were randomized 2:1 to receive pleconaril, 5 mg/kg/dose orally three times a day or placebo for 7 days. Evaluations included pharmacokinetic determinations, safety laboratory testing, serial culture and PCR assays and clinical evaluations. RESULTS: Of 21 evaluable subjects 20 were confirmed with EV infection (12 pleconaril, 8 placebo). Among pleconaril-treated subjects 26 of 29 peak and trough pleconaril levels exceeded the 90% inhibitory concentration for EVs. A median 3.5-fold drug accumulation occurred between Days 2 and 7. Pleconaril was well-tolerated, although twice as many adverse events occurred ...

Type 1 diabetes is known as to be caused by complex conversation between genetic susceptibility, the disease fighting capability, and environmental elements, say the authors. Although cue for genetic predisposition has been elucidated, proof also points to involvement of enterovirus infection, including infections such as poliovirus, Coxsackievirus A, Coxsackievirus B, and echovirus. To investigate the link between EV an infection and subsequent type 1 diabetes, the researchers used nationwide population-based data from Taiwans national medical health insurance system.. ...
Enterovirus 71 (EV71) is a common cause of Hand, foot, and mouth disease (HFMD) and may also cause severe neurological diseases, such as encephalitis and poliomyelitis-like paralysis. To examine the genetic diversity of EV71, we determined and analyzed the complete VP1 sequences (891 nucleotides) from nine EV71 strains isolated in Fuyang, China. We found that nine EV71 strains isolated were over 98% homologous at the nucleotide level and 93%-100% homologous to members of the C4 subgenogroup. At the amino acid level, these Fuyang strains were 99% -100% homologous to one another, 97%-100% homologous to members of the C4 subgenogroup, and the histidine(H) at amino acid position 22 was conserved among the Fuyang strains. The results indicate that Fuyang isolates belong to genotype C4, and an H at position 22 appears to be a marker for the Fuyang strains.

AB - BackgroundOral poliovirus vaccine (OPV) is less immunogenic in low- or middle-income than in high-income countries. We tested whether bacterial and viral components of the intestinal microbiota are associated with this phenomenon.MethodsWe assessed the prevalence of enteropathogens using TaqMan array cards 14 days before and at vaccination in 704 Indian infants (aged 6-11 months) receiving monovalent type 3 OPV (CTRI/2014/05/004588). Nonpolio enterovirus (NPEV) serotypes were identified by means of VP1 sequencing. In 120 infants, the prevaccination bacterial microbiota was characterized using 16S ribosomal RNA sequencing.ResultsWe detected 56 NPEV serotypes on the day of vaccination. Concurrent NPEVs were associated with a reduction in OPV seroconversion, consistent across species (odds ratio [95% confidence interval], 0.57 [.36-.90], 0.61 [.43-.86], and 0.69 [.41-1.16] for species A, B, and C, respectively).

Hand, foot, and mouth disease (HFMD) is a common infection caused by a group of viruses. It typically begins with a fever and feeling generally unwell. This is followed a day or two later by flat discolored spots or bumps that may blister, on the hands, feet, and mouth, and occasionally buttocks and groin. Signs and symptoms normally appear 3-6 days after exposure to the virus. The rash generally goes away on its own in about a week. Fingernail and toenail loss may occur a few weeks later, but will regrow with time. The viruses that cause HFMD are spread through close personal contact, through the air from coughing, and the feces of an infected person. Contaminated objects can also spread the disease. Coxsackievirus A16 is the most common cause and Enterovirus 71 is the second-most common cause. Other strains of coxsackievirus and enterovirus can also be responsible. Some people may carry and pass on the virus despite having no symptoms of disease. Other animals are not involved. Diagnosis can ...

The genetic plasticity of viruses with RNA genomes results from high mutation rates and genetic recombination, facilitating the emergence of new epidemic viral strains. We study genetic and biological aspects of these viruses from fundamental and public-health standpoints, focusing on enteroviruses.. Human enteroviruses belong to the Picornaviridae family, a large group of human and animal pathogens. They mostly cause asymptomatic intestinal infections, but they can also cause acute damage to the central nervous system leading to meningitis, encephalitis, or even flaccid paralysis, which is mostly due to infections with poliovirus (poliomyelitis) and enterovirus A71 (EV-A71).. In 1988, the WHO established a poliomyelitis eradication program based on massive vaccination campaigns with oral polio vaccine (OPV). This vaccine consists of live attenuated strains that multiply to high titers in the intestine. There is also an inactivated virus vaccine. Following this campaign, a marked decrease in the ...
Enteroviruses (EV) can cause severe neurological and respiratory infections, and occasionally lead to devastating outbreaks as previously demonstrated with EV-A71 and EV-D68 in Europe. However, these infections are still often underdiagnosed and EV typing data is not currently collected at European level. In order to improve EV diagnostics, collate data on severe EV infections and monitor the circulation of EV types, we have established European non-polio enterovirus network (ENPEN). First task of this cross-border network has been to ensure prompt and adequate diagnosis of these infections in Europe, and hence we present recommendations for non-polio EV detection and typing based on the consensus view of this multidisciplinary team including experts from over 20 European countries. We recommend that respiratory and stool samples in addition to cerebrospinal fluid (CSF) and blood samples are submitted for EV testing from patients with suspected neurological infections. This is vital since ...
Infecting the enterovirus can be from a sick person or from a carrier that is not sick, but is only a carrier of infection. Most often enterovirus children are ill. It is transmitted by the fecal-oral and food way, therefore, it is said that a person was poisoned while eating food. Often infection is due to infected vegetables and fruits that have been badly washed. Enterovirus gets to the fruit during irrigation with sewage, and then we are on the table.

Fourteen children across California have been sickened by enterovirus D68 so far this year, but a separate investigation has revealed that the rare respiratory illness was present in 2012 in patients who suffered some paralysis, state health officials said Friday.. The California Department of Public Health identified 35 patients with paralysis and spinal cord illnesses since 2012. Of those patients, three had the virus known as EV-D68. There were two in 2012 and one this year. The finding raises the question but doesnt answer conclusively if there is a link between the rare respiratory illness and limb paralysis. Because EV-D68 was found in respiratory specimens from these patients, it is not known whether EV-D68 was a cause of paralysis or a coincidental finding, said Dr. Gil Chavez, state epidemiologist for the Center for Infectious Diseases at the state health department. The CDC is investigating reports of paralysis and neurological issues in several children in Colorado. Health experts ...
Enterovirus D68 (EV-D68) is a human respiratory virus associated with acute flaccid myelitis, a rare paralytic disease primarily occurring in young children. To develop a potential therapeutic agent for this emerging disease, Vogt et al. screened B cells from participants with past EV-D68 infection for virus-binding antibodies and isolated a series of human monoclonal antibodies (mAbs). One mAb that neutralized virus from all EV-D68 clades tested was shown by cryo-electron microscopy to bind a conformational epitope on the viral capsid surface. This highly cross-reactive mAb also protected immunodeficient mice from EV-D68-induced respiratory and neurological disease when given as prophylaxis or therapy. This research sets the stage for clinical testing of antibody therapy in patients with severe EV-D68 disease when the next virus outbreak occurs. ...
