BACKGROUND: Hand, foot and mouth disease (HFMD) caused by enterovirus A71 (EV-A71) is associated with acute neurological disease in children. This study aimed to estimate the burden of long-term sequelae and death following severe HFMD. METHODS: This systematic review and meta-analysis pooled all reports from English and Chinese databases including MEDLINE and Wangfang on outbreaks of clinically diagnosed HFMD and/or laboratory-confirmed EV-A71 with at least 7 days' follow-up published between 1st January 1966 and 19th October 2015...

In the event of an intentional or accidental incursion of a transboundary animal disease (TAD) virus into the US, a major concern to the meat industry would be the potential contamination of packing plants by processing infected animals. TAD agents such as foot and mouth disease virus (FMDV), African swine fever virus (ASFV) and classical swine fever virus (CSFV) are found in swine products such as blood and feces and are present in the tissues of infected animals. To test the disinfection of TAD viruses in a pork-packing environment, a previously developed disinfection assay was used to test two biocides currently used by industry sanitarians, against TAD viruses dried on industry relevant surfaces in saline or swine products...

Hand, foot, and mouth disease (HFMD) is an infectious disease that mainly affects infants and children, causing considerable morbidity and mortality worldwide. HFMD is commonly caused by enterovirus 71 (EV71) and coxsackieviruses A16 (CVA16), A6 (CVA6), and A10 (CVA10). Formalin-inactivated EV71 vaccines are currently available in China; however, these vaccines fail to confer cross-protection against infections by other HFMD-causing enteroviruses, highlighting the necessity of developing a multivalent HFMD vaccine...

Hand, foot and mouth disease (HFMD) primarily affects children younger than 5 years of age. Recently, HFMD has ranked as the top notifiable infectious disease in China. In December 2015, China approved two novel inactivated enterovirus 71 vaccines (EV71 vaccines) for HFMD. Parents' acceptance is often essential for vaccination program success. The goal of this study was to identify willingness and influential factors to vaccinate among parents of kindergarteners in Guangzhou, China. A cross-sectional survey of face-to-face interviews was conducted from March to July 2016...

Foot-and-mouth disease serotype O viruses (FMDV/O) are responsible for the most outbreaks in FMD endemic countries. O1/BFS is one of the recommended FMD/O vaccine strains by World Reference Laboratory for FMD. In the current study, FMDV/O1 BFS vaccine strain and serotype O field isolates (45) were analyzed phylogenetically and antigenically to gain more insight into the genetic and antigenic characteristics of the vaccine strain and field isolates. O1/BFS showed similarity with 89% of the field isolates using a virus neutralization test (VNT)...

Phylogenetic analyses of foot-and-mouth disease type A viruses in the Middle East during 2015-2016 identified viruses belonging to the A/ASIA/G-VII lineage, which originated in the Indian subcontinent. Changes in a critical antigenic site within capsid viral protein 1 suggest possible evolutionary pressure caused by an intensive vaccination program.

Enterovirus 71 (EV71) is one of the most common pathogens of hand, foot, and mouth disease (HFMD). A rapid reverse transcription recombinase polymerase amplification (RT-RPA) assay was established to detect EV71 subgenotype C4 (EV71-C4). The 95% detection limit of the RT-RPA was 3.767 log10 genomic copies (LGC)/reaction. The specificity was 100%. In a clinical sample evaluation, this approach demonstrated sufficient clinical performance when compared with a commercial RT-qPCR diagnostic kit. Thus, the RT-RPA assay may be a promising alternative for the detection of EV71-C4...

Hand, foot, and mouth disease is a common exanthem linked to infection with several non-polio enteroviruses. This case of an 11-year-old boy with an enteroviral infection limited to areas of sunburn is an atypical presentation of hand, foot, and mouth disease. Recognition of this unusual distribution will allow pediatricians and pediatric dermatologists to appropriately manage and counsel patients and parents.

Enterovirus (EV) 71 infection has been widely acknowledged as the leading cause of severe hand, foot and mouth disease (HFMD), which may rapidly lead to fatal pulmonary edema. In this study, we established a mouse model for EV71 infection exhibiting high incidence of severe symptoms with pulmonary edema. Mast cells (MCs) accumulation, activation and allergic inflammation were found in the brains, lungs and skeletal muscle of mice after EV71 infection, especially in the lungs of mice. Levels of histamine, platelet-activating factor (PAF), interleukin (IL)-4, IL-5, IL-13, tumor necrosis factor-α (TNF-α), nitric oxide (NO), endocrine gland-derived vascular endothelial growth factor (EG-VEGF) and noradrenaline (NA) were increased in EV71-infected lungs...

Enteroviruses (EV) are associated with a range of serious infections, including aseptic meningitis, hand foot and mouth disease, myocarditis, acute flaccid paralysis and encephalitis. Improved methods for assessing EV genotypic diversity could assist molecular epidemiology studies, clinical diagnosis and environmental surveillance. We report new methods for EV genome amplification, and subsequent genotyping using the miniaturised MinION sequencing device. Importantly, this next-generation sequencer enabled correct strain-level assignment of identity for the EV-A71 isolate assessed, where strains with up to 99...

Rhinoviruses (RVs) are the pathogens most often responsible for the common cold, and are a frequent cause of exacerbations in asthma, chronic obstructive pulmonary disease and cystic fibrosis. Here we report the discovery of IMP-1088, a picomolar dual inhibitor of the human N-myristoyltransferases NMT1 and NMT2, and use it to demonstrate that pharmacological inhibition of host-cell N-myristoylation rapidly and completely prevents rhinoviral replication without inducing cytotoxicity. The identification of cooperative binding between weak-binding fragments led to rapid inhibitor optimization through fragment reconstruction, structure-guided fragment linking and conformational control over linker geometry...

Hand, foot and mouth disease (HFMD) is a pediatric disease associated with infection by enterovirus (EV) genotypes. The major HFMD EV pathogens are enterovirus A71 (EVA71) and coxsackievirus A16 (CVA16); however, recently, coxsackievirus A6 (CVA6) and coxsackievirus A10 (CVA10) have also emerged. EV genotypes cannot be distinguished on clinical grounds and a new methodology for the rapid detection of the four major HFMD EV genotypes is urgently required. In the present study, a multiplex real-time PCR assay was established for the simultaneous detection of CVA6, CVA10, CVA16 and EVA71...

Collagen is one of the most useful biomaterials and widely applied in functional food and cosmetics. However, some consumers have paid close attention to the safety of mammalian collagens because of the outbreaks of bovine spongiform encephalopathy (BSE), foot-and-mouth disease (FMD), and other prion diseases. Therefore, there is a strong demand for developing alternative sources of collagen, with one promising source being from the process by-products of commercial fisheries. In this report, acid-soluble collagen (ASC-SB) and pepsin-soluble collagen (PSC-SB) from swim bladders of miiuy croaker ( Miichthys miiuy ) were isolated with yields of 1...

Sheep production systems are a major industry in Australia, with a gross value of roughly $4.66 billion; 87.3% of which is attributable to export markets. Exotic diseases such as foot-and-mouth disease (FMD) are a potential threat to the viability of Australia's export market. Previous outbreaks of FMD in developed countries, and challenges in the management of onshore biosecurity, signify the importance of on-farm biosecurity in controlling disease transmission. This study aims to investigate the risk of disease introduction and spread among New South Wales (NSW) sheep properties using FMD as a case study and draw recommendation for the industry...

Previous studies demonstrate that human enterovirus 71 (EV71), a primary causative agent for hand, foot, and mouth disease, activates caspase-3 through the non-structural viral 3C protein to induce host cell apoptosis; however, until now it was unclear how 3C activates caspase-3 and how caspase-3 activation affects viral production. Our results demonstrate that 3C binds caspase-8 and caspase-9 but does not directly bind caspase-3 to activate them, and that the proteolytic activity of 3C is required by the activation of caspase-8, caspase-9, and caspase-3...

Enhancements in the diagnostic capabilities using host biomarkers are currently much needed where sensitivity and specificity issues plague the diagnosis of Hand, Foot and Mouth Disease (HFMD) in pediatrics clinical samples. We investigated miRNome profiles of HFMD saliva samples against healthy children and developed miRNA-based diagnosis models. Our 6-miRNA scoring model predicted HFMD with an overall accuracy of 85.11% in the training set and 92.86% in the blinded test set of Singapore cohort. Blinded evaluation of the model in Taiwan HFMD cases resulted in 77...

BACKGROUND: Nano-PCR is a recent tool that is used in viral diseases diagnosis. The technique depends on the fundamental effects of gold nanoparticles (AuNPs) and is considered a very effective and sensitive tool in the diagnosis of different diseases including viral diseases. Although several techniques are currently available to diagnose foot and mouth disease virus (FMDV), a highly sensitive, highly specific technique is needed for specific diagnosis of the disease. In the present work, a novel AuNPs biosensor has been designed using thiol-linked oligonucleotides that recognize the conserved 3D gene of FMDV...

Infections caused by enteroviruses (EV) and parechoviruses (PeV), members of the Picornaviridae family, are associated with various clinical manifestations, including hand, foot, and mouth disease; respiratory illness; myocarditis; meningitis; and sepsis; and can result in death. The genus Enterovirus includes four species of enterovirus (A-D) known to infect humans, and the genus Parechovirus includes one species (A) that infects humans. These species are further divided into types, some of which are associated with specific clinical manifestations...

Foot-and-mouth disease (FMD) is endemic in China and is predominantly due to foot-and-mouth disease virus (FMDV) serotype O Mya-98 lineage. In recent years, FMDV O/ME-SA/Ind2001 lineage has spread from the Indian subcontinent to South-East Asia, Middle East and Africa, which may pose potential threats for future trans-regional livestock movements. In this study, we identified the appearance of FMDV O/ME-SA/Ind2001 in China; the first time that this virus lineage has been found there. Sequencing and phylogenetic analysis of VP1 sequences revealed that this newly determined strain belongs to O/ME-SA/Ind2001 sublineage d and is closely related to strains that have caused recent outbreaks of FMD in Nepal, Myanmar, Russia and South Korea...

Coxsackievirus belongs to the Enterovirus genus of the Picornaviridae family and is one of the major pathogens associated with human hand, foot, and mouth disease (HFMD). Historically, outbreaks of HFMD have mainly been caused by enterovirus 71 and coxsackievirus A16. Recently, coxsackieviruses A6 and A10 have been associated with increased occurrences of sporadic HFMD cases and outbreak events globally. In this study, the immunogenicity of coxsackieviruses A6, A10, and A16 (CA6, CA10, and CA16), which were inactivated by formalin or β-propiolactone (BPL) under different conditions, was evaluated as multivalent vaccine candidates...
