New detection method for UTI-causing bacteria means better treatment and fewer costs

A new method for identifying bacteria that cause urinary tract infections (UTIs) will lead to faster, more effective treatment and a reduction in costs. The procedure could also be used for the identification of organisms in other bodily fluids, like blood and spinal fluid. Scientists were able to effectively separate and accurately identify bacteria in urine using a technique called Matrix-Assisted Laser Desorption Ionization-Time of Flight (MALDI-TOF) mass spectrometry. Currently, bacteria from urine are identified by biochemical testing of bacterial colonies that grow on agar plates, which takes a minimum of 12 hours, often longer. The MALDI-TOF technique identifies bacteria by analysing their proteins directly from the urine sample, which is faster. "This should mean less patient suffering, fewer complications and a reduction in costs of both diagnosis and therapy," stated Dr. Frank Mosel, who led the study.
