Abstract

We report a case of melioidosis in China and offer a comparison of 5 commercial detection systems for Burkholderia pseudomallei. The organism was misidentified by the VITEK 2 Compact, Phoenix, VITEK mass spectrometry, and API 20NE systems but was eventually identified by the Bruker Biotyper system and 16S rRNA sequencing.

Keywords: Burkholderia pseudomallei; China; bacteria; biochemical identification systems; matrix-assisted laser desorption/ionization time-of-flight mass spectrometry; misidentification.
