Cultivation and lifespan of gonococcus

E. Kadischu. SW Ruan (Arch. F. Derm. U. Syph. Bd 154, H. 2, 1928), having worked for several years with the cultivation of gonococcus, and having tested a number of different culture media, they think that Levinthаlʹya medium is the most convenient and acceptable, however, the technique of its preparation has not yet undergone final development. They modified Levinthal's medium by preparing it with horse or lamb blood and adding 1.8-1.85% agar. The second part of the work is devoted to the study of the lifespan of a gonococcus on everyday objects: sponges, canvas rags and pine sticks. Observing the vital activity of gonococci on these objects under various conditions, room temperature, glacier temperature and in a thermostat, the authors come to the conclusion that gonococci are able to remain viable on wet sponges, pieces of wood and canvas rags for 24 hours at room temperature: in culture liquids, as well as in flowing water, during the same period.
