Abstract

Enterobacter species have increasingly been identified as pathogens over the past several decades. These bacterial species have become more important because most are resistant to cephalothin and cefoxitin, and can produce extended-spectrum beta-lactamase. Enterobacter Asburiae (E. asburiae) is a gram-negative rod of the family Enterobacteriaceae, named in 1986. Since then, there has been only one clinical report of E. asburiae pneumonia. We report a case of E. asburiae pneumonia with cavitation and compare it with the previous case.

  Fig. 1 Enterobacter asburiae pneumonia with cavitation in a 74-year-old man. A. Chest radiograph after radiofrequency ablation for hepatocellular carcinoma is clear. B. Radiograph obtained after 6 months for the evaluation of fever shows a large cavity in the right upper lobe (arrow) and extensive consolidation in the left lung. C. After administration of IV antibiotics (Tazoperan 4.5 g), consolidation in the left lower lobe disappeared. The cavitary lesion in the right upper lobe (arrow) has persisted until now.
