BACKGROUND: Over the past 20 years, Brevundimonas vesicularis has rarely been reported as a pathogen causing human infection. The clinical manifestations of B vesicularis bacteremia and its susceptibility to antibiotics has not been characterized. METHODS: A retrospective study was conducted between 2006 and 2009 in a tertiary-care hospital in southern Taiwan. RESULTS: A total of 22 cases of B vesicularis bacteremia were identified during the study with 86% being community-acquired primary bloodstream infections. Of the 22 patients, 15 (68%) presented with fever, fewer comorbidities, shorter hospital stays, lower mean creatinine levels (1.10 mg/dL vs. 1.74 mg/dL), lower aspartate aminotransferase levels (29.1 IU/L vs. 79.0 IU/L), and lower alanine aminotransferase levels (16.4 IU/L vs. 67.0 IU/L) when compared to afebrile patients. Among the bacterial isolates, 90.9% were susceptible to cefpirome, imipenem and piperacillin/tazobactam while 86.4% were susceptible to gentamicin, amikacin and ciprofloxacin. However, 63.6% of the bacterial isolates were susceptible to ceftazidime, and only 59.1% were susceptible to trimethoprim-sulfamethoxazole (TMP-SMX). The 30-day mortality rate from all causes was 4.5%. CONCLUSION: B vesicularis is able to cause community-acquired and low-mortality primary bloodstream infections. The resistance of B vesicularis to trimethoprim-sulfamethoxazole and ceftazidime limits the choice of available antibiotics for treatment. |
