We modified the capsid protein of a human enterovirus 71 (HEV71) belonging to subgenogroup C4 (HEV71-C4) to generate a mouse virulent strain, based on the genetic information derived from our previous subgenogroup B3 mouse-adapted virus. Infectious clone-derived mutant virus populations containing the capsid protein mutations VP1-Q145E and VP1-Q145G were generated by site-directed mutagenesis of an infectious clone of a subgenogroup C4 strain. Viruses expressing the VP1-Q145E were virulent in 5-day-old BALB/c mice with 100 % mortality rate observed. Skeletal muscle appears to be the primary site of replication of this virus with limb muscle showing severe myositis. Virus was also isolated from spleen, liver, heart and brain of infected mice. This study demonstrates that introducing a key mutation into the HEV71 VP1 capsid protein is able to generate a mouse virulent HEV71 strain from a different genogroup as well as providing an alternative strategy for the generation of mouse virulent HEV71.
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.

During 2005, 764 children were brought to a large childrens hospital in Ho Chi Minh City, Vietnam, with a diagnosis of hand, foot, and mouth disease. All enrolled children had specimens (vesicle fluid, stool, throat swab) collected for enterovirus isolation by cell culture. An enterovirus was isolated from 411 (53.8%) of the specimens: 173 (42.1%) isolates were identified as human enterovirus 71 (HEV71) and 214 (52.1%) as coxsackievirus A16. Of the identified HEV71 infections, 51 (29.5%) were complicated by acute neurologic disease and 3 (1.7%) were fatal. HEV71 was isolated throughout the year, with a period of higher prevalence in October-November. Phylogenetic analysis of 23 HEV71 isolates showed that during the first half of 2005, viruses belonging to 3 subgenogroups, C1, C4, and a previously undescribed subgenogroup, C5, cocirculated in southern Vietnam. In the second half of the year, viruses belonging to subgenogroup C5 predominated during a period of higher HEV71 activity ...
Human enterovirus C99 (EV-C99) belongs to Human enterovirus C. EV-C99 is a positive-sense, single-stranded RNA virus. The genome is approximately 7.4 kb, including a 5ʹ untranslated region (UTR), structural polypeptide P1, nonstructural polypeptides P2 and P3, and a 3ʹ UTR. All EV-C99 strains can be classified into three genotypes, A, B, and C (1). EV-C99 strains have been isolated from acute flaccid paralysis (AFP) patients and from oral polio-vaccinated and healthy individuals (1-4). At present, there are very few EV-C99 sequences available in the GenBank database.. A stool sample of a healthy child in Yunnan, China, was inoculated into human embryonic lung diploid fibroblasts (KMB17) and propagated in up to three passages.

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 ...
A doctor can tell if your child has hand-foot-and-mouth disease by the symptoms you describe and by looking at the sores and blisters. Tests usually are not needed.. Mouth Disease. Your mouth is one of the most important parts of your body. Any problem that affects your mouth can make it hard to eat, drink or even smile.

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

Singapore experienced a large epidemic of hand, foot and mouth disease (HFMD) in 2000. After reviewing HFMD notifications from doctors and child-care centers, we found that the incidence of HFMD rose in September and declined at the end of October. During this period, 3,790 cases were reported. We performed enteroviral cultures on 311 and 157 specimens from 175 HFMD patients and 107 non-HFMD patients, respectively; human enterovirus 71 (HEV71) was the most frequently isolated virus from both groups. Most of the HFMD patients were
Over the past 8 years, human enteroviruses (HEVs) have caused 27 227 cases of hand, foot and mouth disease (HFMD) in Xiamen, including 99 severe cases and six deaths. We aimed to explore the molecular epidemiology of HFMD in Xiamen to inform the development of diagnostic assays, vaccines and other interventions. From January 2009 to September 2015, 5866 samples from sentinel hospitals were tested using nested reverse transcription PCR that targeted the HEV 5′ untranslated region and viral protein 1 region. Of these samples, 4290 were tested positive for HEV and the amplicons were sequenced and genotyped. Twenty-two genotypes were identified. Enterovirus 71 (EV71) and coxsackieviruses A16, A6 and A10 (CA16, CA6 and CA10) were the most common genotypes, and there were no changes in the predominant lineages of these genotypes. EV71 became the most predominant genotype every 2 years. From 2013, CA6 replaced CA16 as one of the two most common genotypes. The results demonstrate the vast diversity of ...

Hand-foot-and-mouth disease begins 3-7 days after exposure to someone with the illness. The illness is highly contagious and spreads by contact with the mouth, saliva, and skin of an infected person. Children are more susceptible than adults. The illness can begin with 1-2 days of fever, sore mouth, decreased appetite, and decreased activity. Shallow ulcers with a red border then form in the mouth. They can occur anywhere within the mouth. These ulcers are often painful for 3-4 days and can remain for 7-10 days. Soon after the ulcers in the mouth form, about half of the children will develop occasionally painful (sometimes itchy) red spots or blisters on the hands and feet. These spots are usually small and fade without crusting over in 2-7 days. A few children will develop stomach pain, diarrhea, achy joints, swollen lymph glands at the neck, a dramatic decrease in activity, or red spots or blisters on areas other than the hands and feet. Most children will have only one case of ...
Who is at risk for hand, foot, and mouth disease?. Hand, foot, and mouth disease (HFMD) occurs mainly in children under 10 years old, but may occur in adults as well. HFMD is most common in children in child care settings, where diaper changing and potty training are constant and little hands are often in and out of the mouth frequently. Everyone is at risk for infection, but not everyone who is infected gets ill. Children are more likely to experience illness because they may not have immunity from a previous infection. Infection results in immunity to the specific virus, but a second episode may occur resulting from a different type of enterovirus. HFMD is more common in the summer and early autumn months. ...
During fall 2008, an outbreak of hand, foot, and mouth disease (HFMD) with onychomadesis (nail shedding) as a common feature occurred in Finland.

A close relative of poliovirus, enterovirus 71 (EV71) is regarded as an important neurotropic virus of serious public health concern. EV71 causes Hand, Foot and Mouth Disease and has been associated with neurological complications in young children. Our limited understanding of the mechanisms involved in its neuropathogenesis has hampered the development of effective therapeutic options. Here, using a two-dimensional proteomics approach combined with mass spectrometry, we have identified a unique panel of host proteins that were differentially and dynamically modulated during EV71 infection of motor-neuron NSC-34 cells, which are found at the neuromuscular junctions where EV71 is believed to enter the central nervous system ...
