Staphylococcus Aureus Clinical Trial
Official title:
Detection of Methicillin Resistant Staphylococcus Aureus Colonization Using the zNose®, an Ultra-fast Gas Chromatograph
The zNose® MRSA test is a non-invasive breath test for markers of Staphylococcus aureus,
which may predict the probability of bacterial organisms in the anterior nares, throat and
respiratory tract, wounds, and anus and therefore be able to replace or supplement current
active Methicillin Resistant Staphylococcus Aureus (MRSA) surveillance efforts. It consists
of:
- A collection apparatus for collection of volatile compounds from suspected infection
sites onto a sorbent trap or Tedlar bag, as well as for the collection of a separate
sample of room air.
- Analysis of the volatile organic compounds from suspected infection sites and room air
by short acoustic wave gas chromatography.
- Interpretation of the volatile organic compounds with a proprietary algorithm in order
to predict the probability of Staphylococcus aureus infection and colonization.
This study will test the hypothesis that we can identify the presence of MRSA by sampling
the "head space" above culture media of anterior nare samples provided by patients with
MRSA. Additionally, this study will test the hypothesis that we can identify the presence of
MRSA by sampling air exhaled through the nostrils (nasal exhalant).
