The records of 46 enterococcal bacteremia at Tokyo Metropolitan Geriatric Hospital from 1972 through 1984 were reviewed.
Sixteen out of 46 cases were monomicrobial bacteremia and 30 cases were polymicrobial bacteremia. Portal of entry were urinary tract in 15 cases, biliary tract in 10 cases, decbitus in 10 cases, and unknown source in 11 cases. Seven out of the 15 patients with enterococcal urosepsis were monomicrobial bacteremia. On the other hand, almost all patients with enterococcal bacteremia originated from biliary tract and decubitus were polymicrobial. Of the 48 strains indentified to species level, 34 were S. faecalis, 8 were S. faecium and 6 were S. avium. S. faecalis was isolated from 14 out of 15 patients with enterococcal urosepsis. In patients whose portal of entry was biliary tract or decubitus, 3 species were recovered in almost same proportions. Total mortality of the bacteremia was 41.3%. The factors which contributed to poor prognosis were DIC, shock, and antimicrobial treatment during 2 weeks prior to onset of the bacteremia. Portal of entry and polymicrobial bacteremia did not influence the mortality.
