According to the following steps, live cells, injured cells, VNC cells and dead cells of a microorganism in a test sample are detected by flow cytometry:
a) the step of treating the test sample with an enzyme having an activity of decomposing cells other than those of the microorganism, colloidal particles of proteins or lipids existing in the test sample,
b) the step of treating the test sample with a topoisomerase poison and/or a DNA gyrase poison.
c) the step of treating the test sample treated in the steps
a) and b) with a nuclear stain agent, and
d) the step of detecting the microorganism in the test sample treated with the nuclear stain agent by flow cytometry.
根据以下步骤,用流式细胞仪检测测试样品中微生物的活细胞、受伤细胞、VNC 细胞和死细胞:
a) 用一种酶处理测试样品,该酶具有分解测试样品中微生物细胞、蛋白质胶体颗粒或脂质以外的细胞的活性、
b) 用拓扑异构酶毒物和/或 DNA 回旋酶毒物处理测试样品。
c) 处理经上述步骤处理过的试验样品的步骤
c) 用核染色剂处理在 a) 和 b) 步骤中处理过的检测样本,以及
d) 用流式细胞仪检测经核染色剂处理的测试样本中的微生物。
