Rapid micro-carbohydrate test for confirmation of Neisseria gonorrhoeae.

摘要

A rapid carbohydrate utilization procedure for the confirmation of Neisseria gonorrhoeae and identification of other Neisseria species has been developed. This method utilizes both preformed enzymes, introduced in a heavy inoculum, and enzymes formed by the microorganisms as a result of growth in a small volume of super-enriched medium. Expected carbohydrate reactions were produced by 383 clinical isolates of neisseriae and were clearly visible within 4 h of incubation. The combined use of disposable glass tubes (6 by 50 mm) and microamounts of media (0.05 ml) make this method not only rapid, but also low in cost.
