title: The diagnostic and therapeutic significance of antimicrobial antibody titer in the bacteremia.
abstract: Antimicrobial antibody titer (AMT) in the sera was determined in 5 patients with infective endocarditis (IE), 8 with septicemia without endocarditis, 3 with fungemia, and 4 with false-positive blood culture. AMT in cases of IE in the early stage of clinical course was over 350 and decreased to less than 50 with clinical improvement following appropriate antibiotic therapy. AMT in cases of septicemia without endocarditis was over 20 and less than 200 and the titer in patients with false-positive blood culture was less than 10. AMT in cases of fungemia without endocarditis ranged from 200-800.
