Abstract:Objective: To establish an EV71 infection model in ICR neonatal mice and provide a practical animal model for evaluation of EV71 vaccines and antiviral drugs. Methods: The 1day ICR mice were infected with the EV71 G03 virus strain through intracerebroventricular injection to establish animal models. After routine euthanizingly killed animals, their various organs and tissues were collected to perform RTPCR analysis of the viral nucleotide acids. In addition, pathological observation, immunohistochemical staining and the Western blotting were used to identify the expression of viral protein 1(VP1). Results: Pathological observation found that after infection, specific pathological changes, such as bleeding, inflammatory cell infiltration, appeared in the myocardium tissue, lung tissue, skeletal muscle, small intestine, brain tissue and other organs of mice. Immunohistochemical staining showed that all five tissues of the infected mice had EV71 virusspecific antigen distribution. Western blotting analysis demonstrated that EV71 VP1 protein was expressed in all five tissues. Conclusion: The onedayold ICR neonatal EV71infected mouse model was successfully established.
