Vergleich der ergebnisse der O2-verbrauchsmessung mit einem konventionellen bakteriologischen verfahren an blasenpunktionsharnen: Comparison between the O2-consumption method and a conventional bacteriological method by the example of urines obtained by puncture

Summary A method is described which utilizes the O 2 consumption of aerobes and facultative aerobes from urinary tract infections for their detection. Urines obtained by puncture and the corresponding midstream urines were examined for verification. Irrespective of secondary contamination and the presence of non-causative organisms, the O 2 consumption method permits the detection of a bacterial urinary tract infection within 1 h. When this method was used, a comparison between midstream urine and urine obtained by puncture showed a complete coincidence. The O 2 method has shown a sensitivity of 96.9% at a specificity of almost 100% for bacterial concentrations of more than 105/ml in the urine obtained by puncture.
