Bruker Biotyper MALDI TOF Mass Spectrometer versus BD Phoenix Automated Microbiology System Identification of Gram-Negative Bacilli2

Slide 20

February 2012

There were limitations of the mass spectrometry system evaluated. Shigella species were not included in the studied database and Shigella species was identified as Escherichia coli. These 2 organisms are so closely related that they are not readily distinguished by this technique. In the same vein, closely related species were not differentiated from one another, including the species comprising the Enterobacter cloacae complex and those comprising the Klebsiella pneumoniae complex. Finally, the database contained some confusing synonyms, variously identifying Stenotrophomonas maltophilia as Stenotrophomonas maltophilia, Pseudomonas hibiscicola, or Pseudomonas beteli for example.
