[Immunological reactivity in tuberculosis in children].

Immunological reactivity was assessed comparatively in respiratory, intrathoracic and osteoarticular, urinary tuberculosis (122, 133, 38 children, respectively, versus 44 controls). References for age were made. The changes in immune system varied in nature, severity and relationships. Basing on these findings the author has created a complex of most informative tests in the diagnosis of childhood tuberculosis adjusted for age and site of the infection focus.
