An evaluation was made of the efficacy of 35% Hydrogen Peroxide Vapour (HPV) against FMDV in a biosafety facility. Biological indicators (BIs) were produced using three serotypes of FMDV, all with a titre of ≥10(6) TCID50 /ml. Fifteen BIs of each serotype were distributed across 5 locations, throughout a 30m(3) Air Lock chamber, producing a total of 45 BIs. 35% HPV was generated and applied using a Bioquell vaporisation module located in the centre of the chamber. After a dwell period of 40 minutes, the HPV was removed via the enclosures air handling system and the BIs were collected...

Foot-and-mouth disease virus (FMDV) capsid precursor protein P1-2A is cleaved by viral-encoded 3C protease (3C(pro)) to generate VP0, VP3, VP1 and 2A proteins. It was reported earlier that substitution of a single amino acid residue within the 2A peptide sequence (L2P) blocked the 3C(pro) mediated VP1/2A cleavage and produced 'self-tagged' FMDV particles containing uncleaved 2A-peptide. To determine whether the uncleaved 2A-peptide can function as a target structure to harbour and display exogenous epitope on FMDV particles, a full-length FMDV cDNA clone containing a HA-tag within the uncleaved 2A-peptide sequence was constructed...

Foot and mouth disease is a highly contagious disease affecting cloven footed animals. Vaccination using inactivated virus is followed to control the disease. As the immune response conferred by the inactivated vaccine is short lived, there is a need for an alternate vaccine with increased duration of immunity. Inclusion of adjuvant which enhances B and T cell responses is one of the strategies to increase the duration of immune responses of the vaccine. Interleukin 15 is one such a cytokine which improves the cell mediated immune response and also involved in the maintenance of memory T and B cells...

Human enterovirus 71 (EV71) is a major causative pathogen of hand, foot and mouth disease (HFMD) and has caused outbreaks with significant mortality among young children in the Asia-Pacific region in recent years. Towards developing a vaccine for this disease, we have expressed and purified EV71 virus-like particles (VLPs), which resemble the authentic virus in appearance, capsid structure and protein sequence, from insect cells (Sf9) using a multistep chromatography process. We demonstrated intracellular localization of the VLPs in host cells by in situ immunogold detection, electron microscopy and immunofluorescence...

Encephalomyelitis is a well-known complication of hand, foot, and mouth disease (HFMD) due to Enterovirus 71 (EV71) infection. Viral RNA/antigens could be detected in the central nervous system (CNS) neurons in fatal encephalomyelitis but the mechanisms of neuronal cell death is not clearly understood. We investigated the role of absent in melanoma 2 (AIM2) inflammasome in neuronal cell death, and its relationship to viral replication. Our transcriptomic analysis, RT-qPCR, Western blot, immunofluorescence and flow cytometry studies consistently showed AIM2 gene up-regulation and protein expression in EV-A71-infected SK-N-SH cells...

BACKGROUND: Coxsackieviruses are members of a group of viruses called the enteroviruses, which may cause respiratory and gastrointestinal symptoms, erythema, meningoencephalitis, myocarditis, pericarditis, and myositis. Unilateral acute idiopathic maculopathy caused by coxsackievirus A16 has been associated with hand, foot, and mouth disease, but only a few reports describe retinitis associated with coxsackievirus serotype B3 or B4. We report a case of bilateral multifocal obstructive retinal vasculitis that developed after coxsackievirus A4 infection...

The emergence and disappearance of antigenic variants of foot-and-mouth disease virus (FMDV) during a field outbreak occurs periodically due to the volatile nature of its genome. In the present analysis, change in antigenic behavior of serotype O FMDV during the serial cytolytic passage in the absence of immune pressure was observed. Initially, the isolate showed a poor antigenic match (relationship value <0.3) with the serotype O vaccine strain and upon serial passage increase in relationship value was observed...

BACKGROUND: Goatpox virus (GTPV) and sheeppox virus (SPPV), which belong to the Capripoxvirus (CaPV), are economically important pathogens of small ruminants. Therefore, a sensitive, specific and rapid diagnostic assay for detection of GTPV and SPPV is necessary to accurately and promptly control these diseases. METHODS: Recombinase polymerase amplification (RPA) assays combined with a real-time fluorescent detection (real-time RPA assay) and lateral flow dipstick (RPA LFD assay) were developed targeting the CaPV G-protein-coupled chemokine receptor (GPCR) gene, respectively...

In 2015 and 2016, Senecavirus A (SVA) emerged as an infectious disease in Brazil, China and the United States (US). In a Colombian commercial swine farm, vesicles on the snout and coronary bands were reported and tested negative for foot-and-mouth disease virus (FMDv), but positive for SVA. The whole-genome phylogenetic analysis indicates the Colombian strain clusters with the strains from the United States, not with the recent SVA strains from Brazil.

Foot-and-mouth disease (FMD) caused by foot-and-mouth disease virus (FMDV), is a highly contagious infectious disease that affects domestic and wild cloven-hoofed animals worldwide. In recent years, outbreaks of serotype A FMD have occurred in many countries. High-affinity neutralizing antibodies against a conserved epitope could provide protective immunity against diverse subtypes of FMDV serotype A and protect against future pandemics. In this study, we generated a serotype A FMDV-specific potent neutralizing monoclonal antibody (MAb), 6C9, which recognizes a conformation-dependent epitope...

Foot-and-mouth disease (FMD) is a contagious disease of cloven-hoofed animals that causes substantial and perpetual economic loss. Apart from the contagious nature of the disease, the FMD virus can establish in a "carrier state" among all cloven-hoofed animals. The Mithun (Bos frontalis), popularly called the "Cattle of Mountain," is found in the geographically isolated, hilly region of north-east India: Arunachal Pradesh, Nagaland, Manipur and Mizoram. Despite the geographical inaccessibility, infection by FMD virus has emerged as the single most devastating disease among Mithun after the eradication of rinderpest from this region...

Host immune response is tightly controlled by negative regulators to avoid excessive immune reactions for homeostasis. Some pathogens may take advantage of host negative regulating system to evade host defense. Our previous report showed that foot-and-mouth disease virus (FMDV) VP1 inhibited TNF-α- and SeV-induced type I interferon response via interaction with cellular protein soluble resistance-related calcium-binding protein (sorcin). Conversely, TNF-α- or SeV-induced type I interferon response increased when sorcin knocked down, leading to inhibition of vesicular stomatitis virus replication...

One of the leading causes of the hand, foot and mouth disease (HFMD) is Enterovirus 71 (EV-A71), displaying symptoms such as fever and ulcers in children but some strains can produce cardiopulmonary oedema which leads to death. There is no FDA-approved vaccine for prevention of severe HFMD. The molecular determinants of virulence for EV-A71 are unclear. It could be a single or a combination of amino acids that determines virulence in different EV-A71 genotype/sub-genotypes. Several EV-A71 strains bearing single nucleotide (nt) mutations were constructed and the contribution of each mutation to virulence was evaluated...

Enterovirus 71 (EV-A71) causes hand, foot and mouth disease in young children and infants, but can also cause severe neurological complications or even death. The double-stranded RNA (dsRNA)-dependent protein kinase R (PKR), an interferon-induced antiviral protein, phosphorylates the regulatory α-subunit of the eukaryotic translation initiation factor 2 in response to viral infection, thereby blocking the translation of cellular and viral mRNA and promoting apoptosis. The cleavage of PKR after infection with poliovirus, a prototype enterovirus, has been reported by others, but the underlying mechanism of this cleavage and its role in viral replication remain unclear...

Plant viruses are suitable as building blocks for nanomaterials and nanoparticles because they are easy to modify and can be expressed and purified using plants or heterologous expression systems. Plant virus nanoparticles have been utilized for epitope presentation in vaccines, for drug delivery, as nanospheres and nanowires, and for biomedical imaging applications. Fluorescent protein fusions have been instrumental for the tagging of plant virus particles. The monomeric non-oxygen-dependent fluorescent protein iLOV can be used as an alternative to green fluorescent protein...

Enterovirus A71 (EV-A71) causes hand-foot-and-mouth disease (HFMD), which may be complicated by fatal encephalomyelitis. Although fecal-oral or oral-oral routes are important in person-to-person transmission, how viral shedding and exposure may predispose individuals to infection remains unknown. We investigated person-to-person transmission by using a model of HFMD and encephalomyelitis based on EV-A71 oral infection of 2-week-old hamsters. Animals (index animals) infected with 10(4) 50% cell culture infective doses of virus uniformly developed severe disease four days post-infection (dpi), whereas littermate contacts developed severe disease after six to seven days of exposure to index animals...
