Identification of carbohydrate structures that are possible receptors for Neisseria gonorrhoeae.

چکیده
Different strains and isogenic variants of Neisseria gonorrhoeae were assayed for their ability to bind glycolipids extracted from various sources. Among a large number of reference glycolipids, binding was observed only to lactosylceramide [Gal(beta 1-4)Glc(beta 1-1)Cer], isoglobotriaosylceramide [Gal(alpha 1-3)Gal(beta 1-4)Glc(beta 1-1)Cer], gangliotriaosylceramide [GalNAc(beta 1-4)Gal(beta 1-4)Glc(beta 1-1)Cer], and gangliotetraosylceramide [Gal(beta 1-3)GalNAc(beta 1-4)Gal(beta 1-4)Glc(beta 1-1)Cer]. The latter two glycolipids bound gonococci with the highest affinity. Lactosylceramide and gangliotriaosylceramide were found in glycolipid preparations from ME180 cells, an epithelial cell line derived from a human cervical carcinoma, and thus are possible receptors for gonococci. The gonococcal surface component that bound the above glycolipids is a protein distinct from pilin and protein II.

Rapid carbohydrate utilization test for the identification of Neisseria gonorrhoeae.
A rapid carbohydrate utilization test for the identification of N. gonorrhoeae was investigated, with reference to its use in a routine diagnostic laboratory. The rapid test was shown to give accurate results in agreement with those of a conventional serum-free sugar medium. Because of the shorter time taken for the confirmation of an isolate, and several other advantages, it is proposed that t...
متن کاملRapid micro-carbohydrate test for confirmation of Neisseria gonorrhoeae.
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 clini...

Methods for identifying Neisseria spp. include conventional and modified carbohydrate degradation procedures, chromogenic enzyme substrate tests, and immunologic coagglutination tests for Neisseria gonorrhoeae. In this study, we evaluated the abilities of the RIM-N carbohydrate degradation system (American MicroScan, Campbell, Calif.), the Gonochek II enzymatic identification system (Du Pont Co...

Bacterial vaginosis or non-specific vaginitis describes the disease caused by a change in the normal Flora of the vagina, which leads to the elimination of Lactobacilli, generating hydrogen peroxide and excess growth of bacteria, particularly anaerobic bacteria. This disease is the most prevalent infection of the female genital tract, and the rate of frequency of anaerobic bacteria, specificall...
