Bacteremia due to Brevundimonas vesicularis.

In the original article on Brevundimonas vesicularis bacteremia, Zhang et al described the clinical characteristics and microbiological features of 22 patients with primary B. vesicularis bacteremia who were being treated in a medical center in southern Taiwan during 2006e2009. In this study, microbiological identification was performed with an API 20 NE system (bioMérieux, Marcy L’etoile, France) or Phoenix100 automated system (Becton, Dickinson, and Company, Sparks, MD, USA). However, there are some differences between commercial automated identification methods and 16s rRNA gene sequencing, as shown in another case series study conducted in Taiwan. Of the four strains identified as B. vesicularis by the Phoenix system, three were finally confirmed as Brevundimonas nasdae and one as Brevundimonas diminuta by the 16s rRNA gene sequencing. Again, four isolates were identified as B. diminuta or B. vesicularis by the VITEK 2 system (bioMérieux), which were finally confirmed as B. nasdae by 16s rRNA gene sequencing. Therefore, in addition to commercial identification methods, further identification by amolecularmethodmight
