Characterization of Neisseria elongata subsp. glycolytica isolates obtained from human wound specimens and blood cultures.

Four slightly yellow-pigmented, alpha-hemolytic, gram-negative coccobacilli, three from wound specimens and one from multiple blood cultures of a patient with endocarditis, were identified as Neisseria elongata subsp. glycolytica on the basis of their overall biochemical and genetic similarities to this subspecies. These strains resembled N. elongata in their guanine-plus-cytosine contents (55.6 to 57.1 mol%) and in their overall cellular fatty acid profiles, which are characterized by large amounts of 16:0, 16:1 omega 7c, and 18:1 omega 7c fatty acids. Their identities were confirmed by species-level DNA relatedness (hydroxyapatite method) to the type strains of all three N. elongata subspecies. The biochemical profiles and cultural characteristics of these strains resembled those of the type strain of N. elongata subsp. glycolytica except for the production of a weak yellow growth pigment and alpha-hemolysis on sheep blood agar. They differed from N elongata subsp. elongata by the production of catalase, by the production of alpha-hemolysis on sheep blood agar, and by acid production from D-glucose. They differed from N. elongata subsp. nitroreducens by the production of catalase and an inability to reduce nitrate. These studies suggest a pathogenic potential for N. elongata subsp. glycolytica, usually considered to be a transient colonizer in humans
