Researchers from the Technical University of Munich have developed two modified disk diffusion methods that may drastically reduce the time for antibiotic susceptibility testing in urinary tract infections (UTIs) while preserving accuracy. Traditional testing involves prolonged bacterial isolation, leading to delays in targeted therapy. The new approaches, which take bacterial concentration into account, significantly increase identification accuracy and may provide physicians with vital susceptibility data up to a day faster, ultimately aiding antimicrobial stewardship.
1. Two new methods may speed up antibiotic susceptibility testing for UTIs. 2. Traditional testing delays treatment due to overnight bacterial isolation. 3. New approaches consider bacterial concentration for accurate results. 4. Targeted susceptibility data can be obtained 24 hours faster. 5. Proteus mirabilis presents challenges in inhibition zone interpretation. 6. Future work needs broader validation and integration into automated systems. 7. The study claims substantial clinical and antimicrobial stewardship benefits.
