Abstract
Klebsiella pneumoniae, classified as facultative enteric Gram-negative rods, was previously believed to cause few diseases. Recently, however, K.pneumoniaehas been frequently isolated from infections occurring in immunocompromised hosts. We describe a case of liver abscess and maxillary sinusitis due toK. pneumoniaein a previously healthy 30-year-old man. Both infections were found concurrently, and onlyK. pneumoniaewas isolated. Pyogenic liver abscess is often associated with distant infectious lesions, such as endophthalmitis, osteomyelitis, pulmonary abscess, or purulent meningitis; however, there has been no previous report describing an association with maxillary sinusitis.
Pulsed-field gel electrophoresis (PFGE) suggested similarities between both isolated strains ofK. pneumoniae.
