- Scientists analysed volatile organic compounds (VOCs) given off by two common bugs that infect lungs: Pseudomonas aeruginosa and Staphylococcus aureus;
- Mice infected with the bacteria had their breath sampled after 24 hours;
- The test could tell the species of bacteria apart and also identified two strains of one of the bugs
Results are published in the Journal of Breath Research.
Dr Jane Hill, one of the US scientists from the University of Vermont, said:
A simple breath test could be used to diagnose lung infections such as TB by identifying bacterial "fingerprints", scientists have said.
Researchers from the University of Vermont distinguished between different types and strains of bacteria by testing the breath of mice.
A scaled up version of the technique could reduce the time it takes to diagnose lung infections in humans from days and weeks to just minutes, it is claimed.
