THE SKIN often enables one to a ascertain whether or not a person has had adequate exposure to a particular infectious or parasitic agent. This ability of recording more or less permanently experiences which the skin has undergone has been called ``mnemodermie.'' It will be impossible here to discuss the technical and immunologic details of the various skin test procedures. This has been done adequately in the available textbooks.1 However, a few introductory remarks appear necessary to facilitate the understanding of the tables presented.
In infectious and parasitic diseases, skin tests can be utilized for the following purposes: (1) to establish whether exposure has taken place, (2) to establish whether the skin is in a state of relative susceptibility or resistance and (3) to help in making the diagnosis and prognosis.
The altered reactivity of the skin which occurs after clinical or subclinical exposure to certain infections or infestations may, with or without demonstrable reexposure, last for
