Whole-Blood Amino Acids in Experimentally Induced Typhoid Fever in Man

Abstract
A significant increase in whole-blood amino acids was observed during the incubation period of experimentally induced typhoid fever in man. Ten of the 17 subjects became ill. Retrospective analysis of amino acid changes permitted recognition of impending illness in nine of the 10. A significant increase was not observed in any subject in whom clinically apparent disease did not develop.
