“…In the past few years, reports of various rapid tests for the culture confirmation of Neisseria gonorrhoeae have appeared. However, decreased specificity (1)(2)(3)6), mainly due to cross-reactions with Neisseria cinerea, has been a problem with many of the tests. In an earlier study (4), we reported the sensitivity and specificity of the original Phadebact Gonococcus Test to be 94.3 and 100%, respectively.…”

, N.J.) is used for the definitive identification of Neisseria gonorrhoeae. In this test, boiled organisms are examined by using a 1-min coagglutination technique. A total of 776 Neisseria strains, confirmed to the species level by patterns of acid production from carbohydrates incorporated in cysteine-tryptose agar or morphologically consistent with Neisseria meningitidis and fluorescent antibody negative, were tested by the coagglutination technique. Of the 516 isolates of N. gonorrhoeae, 8 (1.6%) were negative with the OMNI Test. Of the 260 isolates of Neisseria spp. other than N. gonorrhoeae, none showed a positive coagglutination reaction. The Phadebact Monoclonal GC OMNI Test provided rapid, accurate identification of N. gonorrhoeae (sensitivity, 98.4%; specificity, 100%).

“…In contrast, some strains of N. cinerea traditionally considered to be glucose negative (58,95) have given positive glucose reactions in some rapid tests (18,34,63). Studies have shown that strains of N. cinerea do produce carbon dioxide from glucose (17). It is possible that these strains produce acid from glucose but rapidly overoxidize it to carbon dioxide; the weak reaction in glucose may be due to the accumulation of a small amount of acid or to acidification caused by the formation of carbonic acid.…”

HISTORICAL PERSPECTIVES ON THE TAXONOMY OF THE FAMILY NEISSERIACEAE Taxonomy of the Family Neisseriaceae The genus Neisseria belongs to the family Neisseriaceae (95), which has undergone many taxonomic changes (14, 15, 19, 74, 75, 80) that are summarized in Table 1. The genus Neisseria was assigned to the family Coccaceae until 1948 (74), when it was reassigned as the type genus in the family Neisseriaceae (75). The family Neisseriaceae at that time also contained the strictly anaerobic Veillonella spp. (14, 19). The family Neisseriaceae now contains the genera Neisseria, Moraxella, Acinetobacter, and Kingella (14), which are differentiated from each other by cell morphology, oxidase and catalase reactions, the presence of carbonic anhydrase, the production of acid from glucose, the ability to reduce nitrite, the presence of thymidine phosphorylase, nucleoside deoxyribosyl transferase, and thymidine kinase, and the presence of true waxes in the cell wall (14). The genus Neisseria contains species that are isolated from humans and other animals. The human species have undergone few taxonomic changes. The most notable change in the taxonomy of the family has been a result of genetic studies. These led to the reassignment of N. catarrhalis to the genus Branhamella (25) and the inclusion of B. catarrhalis as a subgenus in the genus Moraxella (14, 15). Because subgenus and subspecific epithets are not used (90), strains of B. catarrhalis should correctly be called Moraxella catarrhalis. However, because B. catarrhalis is distinctly different from the Moraxella spp. in cell morphology and has recently been recognized as a pathogen (21, 27, 68), the name B. catarrhalis is commonly used, although no formal request has been made to have the name conserved taxonomically. Branhamella catarrhalisc Moraxella lacunata M. bovis M. nonliquefacians M. phenylpyruvica M. osloensis M. kingii M. "urethralis" M. atlantae Acinetobacter calcoaceticus Kingella kingae K. indologenes K. denitrificans 5th (1939) Yes Yes Yes Yes Yes Yes Yes h N. caviae, N. cuniculi, and N. ovis were assigned to the subgenus Branhamella (15). 'N. lactamica was first listed in the 8th edition of Bergey's Manual as N. lactamicus, a species incertae sedis, and was listed as N. lactamica in Bergey's Manual of Systematic Bacteriology in 1984 (95). J N. polysaccharea and N. gonorrhoeae subsp. kochii were described after the publication of Bergey's Manual of Systematic Bacteriology (95). N. polysaccharea was first named N. polysacchareae (82). N. kochii has characteristics of both N. gonorrhoeae and N. meningitidis. k The genus Veillonella was included in the family Neisseriaceae until 1974 (80), when it was assigned as the type genus in the family Veillonaceae.

“…Perhaps in part because of the infrequency with which N. cinerea is isolated in the clinical laboratory, care must be taken not to identify this organism as N. gonorrhoeae (1,2,4,5). Laboratory technicians must be familiar with the limitations of the various rapid identification kits used to identify Neisseria species, especially when these isolates are cultured from nongenital sites.…”
