[A comparison of the developmental characteristics of Neisseria gonorrhoeae and Staphylococcus aureus cultures on nutrient media of different compositions].

The growth parameters of gonococcus and staphylococcus strains in liquid medium were determined. The generation time varied within the limits from 0.8 to 1.3 h for gonococcus and from 0.47 to 0.60 h for staphylococcus, the specific growth rate varied from 0.51 to 0.91 h-1 for gonococcus and from 1.68 to 2.11 h-1 for staphylococcus, depending on the concentration of sodium humate and bovine serum in the medium. The growth characteristics of analysed staphylococcus strains did not depend on the presence of plasmids. The gonococcal cultures grown in the liquid nutrient medium containing 20% of bovine serum for 8-11 h were the most physiologically active. Sodium humate added to the medium for cultivation in concentration 0.01% stimulated the growth of N. gonorrhoeae.
