Resumen
Use of the ncbsr4 gene for the diagnosis and prevention of neosporosis and as a marker for the analysis of pathogenesis. The present invention relates to the use of the ncbsr4 gene and the ncbsr4 protein, the expression vectors and the host cells that contain them, for the diagnosis and prevention of neosporosis and, as a specific marker of the bradyzoite phase of n. Caninum, for the analysis of the pathogenesis or efficacy of vaccines against the establishment of chronic infection in the intermediate host. It also refers to the use of the promoter of the ncbsr4 gene for the expression of heterologous genes that allows the study of the molecular mechanisms that determine the conversion of the stage from tachyzoite to bradyzoite and vice versa. In addition, the present invention relates to the development of monoclonal antibodies and monospecific polyclonal sera against the ncbsr4 protein and its recombinant form, which represent an alternative for the serological diagnosis of neosporosis and of chronic n. Caninum infection in animal tissues. . (Machine-translation by Google Translate, not legally binding)
