Abstract
A vesicular, immunogenic, non-pyrogenic complex is obtained from isolates of N. gonorrhoeae by cultivating N. gonorrhoeae on a suitable nutrient medium; harvesting and centrifuging the cells; extracting the cell pellet with TRITON X-100 at alkaline pH; suspending the solids remaining after extraction in aqueous medium and precipitating in the cold with ethanol.
