Abstract
Summary
Human serum transfer tests were conducted upon the lemuroid prosimian, Nycticebus coucang (slow loris). Intradermal injections of allergic sera passively sensitized the skin of the slow loris. Challenge with the allergens affecting the human patients caused erythema, piloerection, blanching, whealing, and extravasation of intravenously injected colloidal dye in the passively sensitized sites. The human allergic serum transfer test may be an aid in ordinal and subordinal classification of species suspected of being related to the Anthropoidea.
Mr. Leonard Harrison, animal caretaker, rendered invaluable aid in maintaining the animals in healthy condition. Mr. Wm. G. Murray filmed the procedures and performed the photographic services. Dr. Raphael Panzani of Marseille, France, supplied the sera from castor bean allergic patients. Dr. C. W. Denko, Ohio State University, supplied the sera from ragweed atopic patients.
