Lack of antibody induction by Histolyn-CYL, a new skin-testing reagent for histoplasmosis.
Histolyn-CYL, a yeast phase skin-test reagent, was administered to 85 histoplasmin-sensitive subjects living in the United States and South America. In a multicenter study, sera were obtained at the time the skin tests were read and again 3 weeks later. In no instance did the skin test induce significant complement-fixing antibody changes or antibodies detected by immuno-diffusion.
