Abstract
Summary
Interferon could not be detected in 50 sera obtained during the acute illness from 42 patients with clinical malaria. Similarly negative results were obtained when 40 sera from patients with subclinical T. cruzi infection were studied.
The authors thank Dr. Wendell H. Hall from the Minneapolis V.A. Hospital who provided some of the malarial sera. Miss J. Balay provided capable technical assistance. Studies of Chagas disease were supported in part by a grant-in-aid from the S. C. Johnson Foundation.
