To identify the isolates, we performed matrix-assisted laser desorption/ionization time-of-flight mass spectroscopy
using MALDI-TOF MS, version 3 (Bruker Daltonik GmbH, Bremen, Germany) and sequenced the D1/D2 region of a large subunit of ribosomal DNA (7,8).
Under the agreement, Agilent is providing a portfolio of instruments valued at more than $1 million, including such advanced technology as microwave plasma-atomic emission spectroscopy (MP-AES), inductively coupled plasma-optical emission spectroscopy (ICP-OES), gas chromatography-mass spectroscopy (GC-MS), gas chromatography-triple quadrupole mass spectroscopy (GC-QQQ), and gas chromatography-quadrupole time-of-flight mass spectroscopy
Three isolates (2 implant isolates and the oropharyngeal isolate) were subsequently characterized by MALDI-TOF-MS (matrix-assisted laser desorption-ionization time-of-flight mass spectroscopy
) Bruker Dalton ics, Fremont, CA, USA) and by 16S rRNA sequencing (5) and partial rpoB (6) gene sequencing (Table).
