WSJM, a simple chemically defined medium for growth of Neisseria gonorrhoeae.
The growth requirements of 135 clinical isolates of Neisseria gonorrhoeae and six American Type Culture Collection reference strains were examined by using a simple chemically defined medium known as Wong-Shockley-Johnston medium, WSJM. The simple liquid medium supported growth of gonococci from an inoculum of 2 X 10(6) colony-forming units ml-1 and yielded 10(10) colony-forming units ml-1 in 10 h in the absence of CO2. Scale-up experiments with the complete medium yielded 5 to 10 g, wet weight, of cells per liter. The complete medium was stable upon storage at 5 degrees C and after lyophilization.
