Abstract Epidemiological, microbiological and clinical characteristics of 14 episodes of Xanthomonas maltophilia bacteremia in 12 seriously immunocompromised hematological patients, admitted to Rigshospitalet in Copenhagen over the 3-year period 1989-91, were evaluated. The results were compared with a randomly selected control group of 25 patients with Escherichia coli bacteremia. Hospital acquired bacteremia was more common among the patients with X. maltophilia bacteremia (p < 0.01). Treatment with broad-spectrum antibiotics before the bacteremic episode was markedly more common among the patients with X. maltophilia bacteremia (p < 0.001). The presence of a central venous catheter and previous treatment with corticosteroids were more frequent in patients with X. maltophilia bacteremia (p < 0.05). The X. maltophilia blood culture isolates were generally resistant to aminoglycosides and most beta-lactams. The mortality rates related to bacteremia caused by X. maltophilia and E. coli were 14\% and 20\%, respectively.
