| Research Abstract |
We established a technique to determine the viability of yeast cells in urine specimens by directly staining with fluorescent dyes, which have different permeability into yeast cells. After staining, yeast cells were analyzed by flow cytometer. Yeast cells in urine specimens from competent patients against infection were mostly classified as injured cells, whereas those from compromised patients were live cells. Also, the increased ratios of injured cells were observed along the improvement of clinical manifestation of compromised diseases. This established procedure provides us with a perspective prognostic indicator for a variety of diseases following the compromised against infections.
