Organisms of the tribe Klebsielleae, comprised of the genera Klebsiella, Enterobacter, and Serratia, had been recognized only rarely as primary pathogens in humans before the introduction of modern chemotherapy. Since that time, however, they, along with other gram-negative bacilli, have assumed increasing importance as causes of serious infection in hospitalized patients (1-4). Within the past 8 years the number of patients with bacteremia due to Klebsielleae has almost doubled in the Boston City Hospital (5) while the number of admissions to that hospital has remained virtually unchanged.
