Abstract
The morbidity and mortality of coxsackievirus A10 (CVA10)-associated hand, foot, and mouth disease (HFMD) have been increasing in recent years, while few studies on the vaccine and animal model of CVA10 have been reported. Here, we first established a CVA10-infected gerbil model and employed it to evaluate the immunoprotective effect of an inactivated CVA10 vaccine. The results showed that gerbils up to the age of 14 days were fully susceptible to CVA10, and all died within five days post-infection by intraperitoneal inoculation. Lethargy, wasting, hind-limb paralysis, and even death could be observed in the CVA10-infected gerbils. Pathological examination suggested that CVA10 has a strong tropism toward muscle tissue, and muscle bundle fracture and muscular fibers necrosis were observed in the limb muscles. Additionally, active immunization results showed that gerbils immunized with the inactivated CVA10 vaccine were 100 % protected from lethal CVA10 challenge. The antisera from vaccinated gerbils also showed high neutralizing titers against CVA10. Based on these results, the CVA10-infected gerbil model was a suitable tool for analyzing the pathogenesis of CVA10 and assessing the protective efficacy of CVA10 candidate vaccines.

Abstract
INTRODUCTION Hand, foot, and mouth disease (HFMD) is a common viral childhood illness, that has been a severe public health concern worldwide, particularly in the Asia-Pacific region. According to epidemiological data of HFMD during the past decade, the most prevalent causal viruses were enterovirus (EV)-A71, coxsackievirus (CV)-A16, CV-A6, and CV-A10. The public health burden of CV-A10-related diseases has been underestimated as their incidence was lower than that of EV-A71 and CV-A16 in most HFMD outbreaks. However, cases of CV-A10 infection are more severe, and its genome is more variable, which has alerted the research community worldwide. Areas covered: In this paper, studies on the epidemiology, laboratory diagnosis, clinical manifestations, molecular epidemiology, seroepidemiology, animal models of CV-A10, and vaccines and antiviral strategies against this genotype are reviewed. In addition, the genetic evolution of circulating strains was analyzed. Expert opinion: Multivalent vaccines against EV-A71, CV-A16, CV-A6, and CV-A10 should be a next-step HFMD vaccine strategy.

Rapid detection of hand, foot and mouth disease enterovirus genotypes by multiplex PCR. J Virol Methods 2018; 258:7-12. [PMID: 29758237 DOI: 10.1016/j.jviromet.2018.05.005] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/27/2018] [Revised: 05/04/2018] [Accepted: 05/10/2018] [Indexed: 11/21/2022]
Abstract
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. The specificity and sensitivity of the assay was determined on a validation panel of clinical samples, comprising cerebrospinal fluid (n = 51), blood (n = 39), feces (n = 58) and throat swabs (n = 29). The results showed that the multiplex real-time PCR exhibited high specificity, no cross-reactivity with other EV genotypes, lower limits of detection for CVA6, CVA10, CVA16 and EVA71 were 4 × 103, 4 × 102, 5 × 102, and 3 × 103 copies/μL, respectively and had comparable sensitivity to singleplex assays testing clinical samples. The multiplex real-time PCR methodology established in this study can be employed for the rapid detection of the four most prevalent HFMD-associated EVs, for epidemiologic surveillance of circulating EV genotypes and for assessing treatment responses and vaccine studies.

Abstract
This data article contains data related to the research article entitled “Rapid detection of enterovirus and Coxsackievirus A10 by a TaqMan based duplex one-step real time RT-PCR assay” (Chen at al., 2017) [1]. Primers and probe sequence design are among the most critical factors in real-time polymerase chain reaction (PCR) assay optimization. Linearity, sensitivity, specificity and precision are the crucial criteria which are used to evaluate the performance of a new method. This data article report the primers and probe design and precision assessment of the new assay. VP1 gene of Coxsackievirus A10 (CV-A10) and 5′-NCR of different enterovirus (EV) serotypes were retrieved from GenBank database and aligned. The intra- and inter-assay variation were assessed using high, medium and low concentration of control plasmid DNA and viral RNA samples.
