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.
