Defining a core breath profile for healthy, non-human primates

Area of Science:

• Biomedical Research
• Pre-clinical Disease Modeling
• Analytical Chemistry

Background:

• Non-human primates are crucial pre-clinical models for human diseases.
• Primate breath analysis has previously identified disease states.
• A non-invasive method to establish a healthy baseline is needed for comparative studies.

Purpose of the Study:

• To define a healthy baseline breath profile in non-human primates.
• To establish a standardized breathprint for future research in macaques.
• To support studies evaluating diseases, therapies, and vaccines.

Main Methods:

• Pilot study involving 30 healthy macaques.
• Breath sample collection using Tedlar bags.
• Analysis via comprehensive two-dimensional gas chromatography-time of flight mass spectrometry (GCxGC-TOFMS).

Main Results:

• Identified 2,017 distinct molecular features in macaque breath.
• Discovered 113 molecules consistently present across all samples.
• Defined a core breathprint of 23 highly abundant and invariant molecules.

Conclusions:

• A critical core of 23 molecules serves as a pragmatic breathprint for healthy primates.
• This baseline profile is valuable for future validation studies.
• Establishes a foundation for non-invasive health monitoring in non-human primate research.
