Enterobacter species have emerged as important nosocomial pathogens. Common reservoirs for these organisms include wounds and the gastrointestinal, urinary, and respiratory tracts. Enterobacter bacteremia typically occurs in patients with long-standing underlying illnesses who received antimicrobial agents before their bacteremia. The wide use of broad-spectrum antibiotics has contributed to the increased prominence of Enterobacter infections. Enterobacter species have a propensity to emerge resistant to the antibiotic therapy administered. Plasmid analysis, restriction endonuclease analysis of total cellular DNA, pulsed-field electrophoresis, and ribotyping can be valuable in investigating the spread of antibiotic-resistant strains.

An 18-month prospective study of Enterobacter bacteremia was conducted in 129 patients. The results indicated that (1) emergence of resistance was more frequent during treatment with third-generation cephalosporins than with other antibiotics; (2) the addition of an aminoglycoside to the cephalosporin did not prevent emergence of resistance; (3) previous treatment with cephalosporins was associated with bacteremia caused by multiresistant Enterobacter species; and (4) infection with multiresistant Enterobacter species was associated with a higher mortality than infection with susceptible strains. It is concluded that avoidance of third-generation cephalosporins for surgical prophylaxis and therapy in patients in whom Enterobacter infections are suspected or proven should lower the prevalence of Enterobacter bacteremias and mortality and prevent the emergence of multiresistance.

Treatment of Enterobacter infection is complicated due to its intrinsic resistance to cephalosporins. Medical records of 192 adults with cancer who had Enterobacter bacteremia were analyzed retrospectively to evaluate the risk factors for and the treatment outcomes in extended-spectrum cephalosporin (ESC)-resistant Enterobacter bacteremia in adults with cancer. The main outcome measure was 30-day mortality. Of the 192 patients, 53 (27.6%) had bloodstream infections caused by ESC-resistant Enterobacter species. Recent use of a third-generation cephalosporin, older age, tumor progression at last evaluation, recent surgery, and nosocomial acquisition were associated with ESC-resistant Enterobacter bacteremia. The 30-day mortality rate was significantly higher in the resistant group. Multivariate analysis showed that respiratory tract infection, tumor progression, septic shock at presentation, Enterobacter aerogenes as the culprit pathogen, and diabetes mellitus were independent risk factors for mortality. ESC resistance was significantly associated with mortality in patients with E. aerogenes bacteremia, although not in the overall patient population.
