Abstract

The bovine herpesvirus type 5 (BHV-5) is an important infectious agent that causes meningoencephalitis in young cattle. The infection due to BHV-5 induces different levels in severity of neurological disease, which depends on the host and viral factors. Similarly, the vesiscular stomatitis virus (VSV) affects primarily cattle, and the infection by this virus is characterized by the formation of vesicular lesions. In murine model the VSV can infect neuroepithelial cells, thus representing a model for acute neurotropic infections caused by viruses. Classically, the rabbit has been used as a experimental model for the BHV-5 infection and the first attempts to use a mouse model for the infection were unsuccessful. However, recently, the use of different strains of young mice allowed the infection by another types of animal herpesviruses. Murine models have been used for the study of the alterations on the central nervous system caused by infections by these type of viruses, once the use of cattle for the investigation of these diseases is generally laborious, expensive and difficult to standardize. Different types of mice strains and the genetically modified mice have demonstrated to be potential tools for the study of etiopathogenesis of viral encephalitis. The central nervous system has unique characteristics during the inflammatory responses due to viral infection, and during the infection, the astrocytes can become activated and express higher levels of glial fibrillary acidic protein (GFAP). Given the above, the purpose of the present study is to evaluate the kinectics of the inflammatory process, as well as the involvement of the glial cells and cytokines in the development of the experimentally encephalitis induced by BHV-5 and VSV in different strains of mice.
