Abstract:
Odoribacter splanchnicus was recently reclassified from the genus Bacteroides. We present the first case of Odoribacter splanchnicus bacteremia following appendicitis. The species was identified using MALDI-TOF mass spectrometry and later confirmed with 16S rRNA sequencing. The patient was successfully managed with surgery and antibiotic administration for two weeks.

MALDI-TOF Mass Spectrometry
5.1K
Mass spectrometry is a powerful characterization technique that can identify and separate a wide variety of compounds ranging from chemical to biological entities, based on their mass-to-charge ratio (m/z). The instruments that allow this detection, known as mass spectrometers, have three components: an ion source, a mass analyzer, and a detector. These spectrometers differ based on the nature of their ion source and analyzers.
