Abstract
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.
