Abstract
This proof-of-concept study used solid-phase microextraction fibers (SPME) to collect headspace vapors from a methicillin sensitive <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">Staphylococcus aureus</i> (MSSA) and a methicillin-resistant <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">Staphylococcus aureus</i> (MRSA) strain grown <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">in vitro</i> in liquid growth medium. The collected molecules were separated and identified using gas chromatography and mass spectrometry (GC/MS). Preliminary results distinguished these two strains and provide a foundation for a biomarker library that could one day serve as a diagnostic tool for identifying specific bacterial infections.
