[Immunologic studies of children in day care centers].

The acute respiratory diseases (ARD) remain an individually and a socially relevant problem in crèches. Immunological processes are also important within the multifactoral genesis. The study presents normal values for intracutaneous tests of the recall-antigens "Tetamun" of the strengths II and III and Tuberculin "CPPD" (Dessau) for different age groups. Statements are made referring the behaviour of the test results at 265 probands of the mentioned age groups with attention to the sex differentiations, infections groups and the kinetics of the specific cellular immunity during the acute phase (A) of the ARD up to fourth week of convalescence. Conclusions are discussed.
