Abbreviations: + = strains typically positive but genetic mutants might be negative; – = negative; V = variable.
* Certain strains grow on selective media for the isolation of N. gonorrhoeae.
† Includes biovars subflava, flava, and perflava. N. subflava biovar perflava strains produce acid from sucrose and fructose and produce polysaccharide from sucrose;
N. subflava biovar flava strains produce acid from fructose; N. subflava biovar flava and N. subflava biovar subflava do not produce polysaccharide.
