On the Growth Requirements of Neisseria Gonorrhoeae

Abstract
Growth of several strains of gonococ-cus has been obtained on a medium consisting of glutamic acid, histidine, glucose, starch, glutathione, Mg and Fe salts, phosphates, NaCl, and agar. Casein hydrolyzate and meat infusion contain unknown factors which greatly stimulate the growth on this medium but which are not essential. Evidence has been obtained showing that the function of starch in the growth of the gonococcus is as a protection against the inhibitory effect of certain samples of agar.
