Investigations on blood and cerebrospinal fluid lymphocytes in patients suffering from tick-borne encephalitis.

This paper deals with the immuno-pathological characteristics of tick-borne encephalitis. With the appearance of neurological signs, there is a strong T cell reaction in th peripheral blood. The following seven days are characterized by the appearance of specific cell-mediated reaction in the peripheral blood; in the cell-mediated reaction in the peripheral blood; in the cerebrospinal fluid, an increasing number of B cells and specific antibodies can be detected. After a week, the percent positivity of cell-mediated immune reactions is higher and there is a T cell dominance in the cerebrospinal fluid. Intact cellular immunity against specific antigen is required for the management of this disease. There are major differences in the results obtained from patients suffering from meningitis alone and those suffering from meningoencephalitis.
