Abstract

The antiswarming agent p-nitrophenylglycerol (PNPG) has been found invaluable for the recognition and isolation of pathogenic bacteria from specimens contaminated with swarming strains of Proteus spp. PNPG is cheap, stable and non-toxic. All strains tested grew well in its presence and produced characteristic morphology. PNPG was without effect on the results of a variety of identification tests performed directly on colonies from media containing PNPG. This permitted identification without the need for further subculture.

摘要

抗群游剂对硝基苯甘油（PNPG）已被证明在从被变形杆菌属群游菌株污染的标本中识别和分离病原菌方面具有极高价值。PNPG价格低廉、性质稳定且无毒。所有测试菌株在其存在的情况下生长良好，并呈现出特征性形态。PNPG对直接在含有PNPG的培养基上的菌落进行的各种鉴定试验结果没有影响。这使得无需进一步传代培养即可进行鉴定。
