Pseudomonas vesicularis is a motile, nonfermentive gram negative bacillus and belongs to group IV of the genus Pseudomonas. Although P. vesicularis is rarely isolated from environmental sources or clinical specimens, the exact pathogenic role of this organism is not confirmed yet. There are rare clinical reports of human infection with this organism in Korea. P. vesicularis produces opportunistic infections in the immunocompromised host or in patient with foreign bodies. Identification of P. vesicularis has been increasing in frequency, since automated or semiautomated identification system of bacteria was introduced. We report 4 cases P. vesicularis bacteremia with a review of literatures. All patients were immunocompromised hosts such as premature newborn, diabetes mellitus, and liver cirrhosis with medical devices. Medical devices were umbilical catheter, urinary catheter, chest tube, and nasogastric tube.
