“…CTA medium has, however, been associated with aberrant utilisation of carbohydrates by both gonococcal and meningococcal isolates. The reaction pertinent to this report is that certain meningococci may fail to utilise maltose and are thus mistaken for gonococci (Kingsbury, 1967;Hollis et al, 1970;Faur et al, 1975b). The failure of some meningococci to utilise maltose has been associated with resistance to sulphonamide and is due to the absence of either maltose permease or maltose phosphorylase activity (Kingsbury, 1967).…”

SUMMARY Three cases of pharyngeal gonorrhoea were misdiagnosed in patients harbouring meningococci which failed to utilise maltose in CTA medium. The microbiological identity of the isolates was established by other means. Although meningococci giving atypical reactions to carbohydrate utilisation tests occur only rarely, the possibility of a misdiagnosis of gonorrhoea, and its social and legal repercussions, should be considered.

“…The appearance of meningococci that fail to utilise maltose is fortunately uncommon; the frequency has ranged from 0 5 to 5 7% of meningococcal isolates from clinical surveys (Hollis et al, 1970;Faur et al, 1975b). This was also our experience.…”

“…On the other hand, glutamate-stimulated citrate metabolism, in this study, proved to be a characteristic shared by a large number of strains of N. meningitidis, but only by an occasional other Neisseria. Of particular interest is the difference between strains of N. meningitidis and N. lactamicus which have been recently separated on the basis of several phenotypic characteristics (5,6) and DNA reassociation (15).…”

Effect of Glutamate on Exogenous Citrate Catabolism of Neisseria meningitidis and of Other Species of Neisseria

Resting cell suspensions of Neisseria meningitidis group B (strain 2091) do not catabolize citrate as the sole substrate to an appreciable degree. When another substrate, such as glutamate, is also present to furnish energy for transport, citrate metabolism is greatly stimulated. Within limits, the amount of CO2 produced from citrate is proportional to the amount of glutamate added. When the cells are disrupted, citrate is degraded at a rapid rate and the stimulatory effect of glutamate is completely eliminated. Pronounced stimulation of citrate metabolism by glutamate was demonstrated in 12 of 13 strains of N. meningitidis tested and only I of 6 strains of N. lactamicus. The remaining strains of N. lactamicus and one each of N. gonorrhoeae, N. flavescens, and N. flava did not utilize significant amounts of citrate in the absence or presence of glutamate. N. catarrhalis shared with Mima polymorpha and Moraxella glucidolytica a capability to catabolize citrate at a rapid rate without added glutamate. It is concluded that tests of glutamate-stimulated citrate metabolism may contribute to species characterization in the genus Neisseria.

Neisseria lactamica septicemia in an immunocompromised patient

Neisseria lactamica was isolated from the blood of a 7-year-old girl who was immunosuppressed from chemotherapy for acute lymphocytic leukemia. She was receiving trimethoprim-sulfamethoxazole prophylactically. The isolate was resistant to trimethoprim-sulfamethoxazole and sensitive to penicillin. The patient responded to intravenous penicillin therapy. The organism did not produce immunoglobulin Al protease.
