[Cultivation of the gonococcus in nutrient broths].

The dynamics of the multiplication of gonococci and the parameters of their growth have been studied in the process of batch cultivation in liquid culture media with different content of bovine blood serum. The protective and stimulating action of the serum on the growth of gonococci has been shown. The optimization of the process of cultivation has been carried out; as a result, the growth of test strains in a culture medium containing no serum has been achieved. Phasic changes in the ultrastructure of gonococci in the process of their cultivation in liquid media have been followed. 9- to 12-hour cultures of gonococci grown in liquid culture media have been found the most valuable and physiologically active.
