The relationship between the mechanical stability and the viability of N. gonorrhoeae (Type 4) in suspension was investigated. A correlation between viability and optical density recordings was often found. However, in spite of increased mechanical stability in solutions with low pH (5-2) or containing Cu++ or sucrose (10 per cent.), these environments were toxic to the gonococci. A viability preserving effect by Mg++ (4 mM), Ca++ (4 mM), spermine (0-5 mM), polyvinylpyrrolidone (10 per cent.), and low temperature (4 degrees C) was demonstrated. The possibility of improving transport media for gonococci is discussed.
研究了淋病奈瑟菌(4型)在悬浮液中的机械稳定性与生存能力之间的关系。生存能力与光密度记录之间经常发现存在相关性。然而,尽管在低pH值(5 - 2)的溶液中或含有Cu++或蔗糖(10%)的溶液中机械稳定性有所提高,但这些环境对淋球菌有毒性。已证明Mg++(4 mM)、Ca++(4 mM)、精胺(0 - 5 mM)、聚乙烯吡咯烷酮(10%)和低温(4℃)具有保存生存能力的作用。讨论了改进淋球菌运输培养基的可能性。
