Background

Hand-foot-and-mouth disease (HFMD) is an infectious disease caused by enteroviruses, which include 20 types, wherein coxsackie virus type a16 (Coxsackievirus type a16, CA 16) and enterovirus type 71 (enterovirus 71, EV 71) are two common important pathogens causing hand-foot-and-mouth disease worldwide, and are epidemic spread alternately or simultaneously in one region. Whereas the marketed EV-A71 vaccine has no cross-protection effect on CV-A16. The detection of neutralizing antibodies is one of the key indicators for carrying out CV-A16 epidemiological investigation and vaccine immunogenicity evaluation. The accuracy of the detection of the titer of the neutralizing antibody is closely related to the detection strain used. The genotype standard detection strain which accords with the epidemic characteristics of the diseases is established, the generation of the strain for detection is fixed, the accuracy and the repeatability of the detection of the vaccine neutralizing antibody are improved, and the immunogenicity evaluation of the vaccine in preclinical and clinical tests can be guaranteed. At present, no standard detection strain of Coxsackie virus A16 exists at home and abroad. It is necessary for enterprises to automatically screen and establish standard detection strains.

In addition, Ningqingjie et al (Ningqingjie, Limin, Yanglan, et al. Cox A16 type hand-foot-and-mouth disease suckling mouse animal model establishment and immune and pathological characteristics [ J ]. Chinese veterinary science report, 2013, 33 (11): 1685:1690.) domesticated by 1-day-old C57BL/6J suckling mice to obtain stable lethal 11-day-old mouse adapted strain CA16-TS, wherein the CA16-TS strain can cause paralysis of mouse hind limb and severe muscle necrosis, and then the body mass gradually reduces to death, and the CA16-TS does not show strong nerve tropism but shows stronger muscle invasion and toxicity. MAO, etc. (Mao Q, Wang Y, Gao R, Shao J, Yao X, Lang S, Wang C, Mao P, Liang Z, Wang J. A neonatal mouse model of coxsackievirus A16 for vaccine evaluation. J Virol. 2012 Nov;86(22):11967-76. doi: 10.1128/JViII.00902-12. Epub 2012 Sep 5. PMID: 22951825; PMCID: PMC 3486452.) A CV-A16 clinical isolate BJCA 08/CA 16 was used to infect 1 day old ICR suckling mice by intracerebral injection to prepare an ICR oral disease model, and the infected mice were found to have strong tendency to muscle tissue, and to cause skeletal necrosis and necrosis of the myocardium. The mouse hand-foot-and-mouth disease model caused by CoxA16 shows obvious symptoms of ataxia, acroparalysis, listlessness and the like on animal behaviors, which are consistent with the current mouse adapted strains. Lijing (Lijing. recombinant Coxsackie A16 virus pathogenesis and candidate vaccine to animal model lethality protection mechanism [ D ]. Changchun: Jilin university 2014.) A16 CC024 virus was infected to 1-day-old mice by cranio-luminal injection, and as a result, the challenged mice showed grade 4 clinical symptoms on day 3, and the grade 4 mice showed the clinical symptoms of limb paralysis, limb muscle and spinal muscle fiber rupture, lung tissue injury and congestion. The results of immunohistochemical analysis show that there are a large number of viral antigens in muscle tissue and lung, and there is an obvious specific tropism for lung tissue. The mouse adaptive strain of the Coxsackie virus A16 type and the application thereof are used for preparing the mouse adaptive strain CV-A16 by using a BalB/c suckling mouse with the age of 4-6 days in China, 201310471154.4 [ P ].2015-05-13.

However, at present, no coxsackie virus A16 type related detection standard strain and challenge strain for vaccine protective evaluation exist at home and abroad.
