Neisseria meningitidis is a facultative pathogen bacterium which is well founded with a number of adhesion molecules to facilitate its colonization in human nasopharynx track. Neisseria meningitidis is a major cause of mortality from sever meningococcal disease and septicemia. The Neisseria meningitidis adhesion, NadA, is a trimeric autotransporter adhesion molecule which is involved in cell ad...
Worldwide Chlamydia trachomatis and Neisseria gonorrhoeae are two of the most prevalent sexually transmitted pathogens. The present study aimed to estimate the prevalence of Chlamydia trachomatis and Neisseria gonorrhoeae infection in women from Taif, western region, KSA. A polymerase chain reaction (PCR) method was carried using DNA extracted from 144 female urine samples. Primer pairs specifi...
Bacteriocin typing has been described previously and proposed for typing gonococci. A survey has been made of 150 strains of N. gonorrhoeae from various places to determine the feasibility of a gonocin typing system. All strains were found to produce an inhibitory substance which inhibited all strains of gonococci tested, one strain of Neisseria flavescens, two strains of Neisseria meningitidis...
Neisseria gonorrhoeae is one of the leading antimicrobial resistance threats worldwide. This study determined the MICs of closthioamide to be 0.008 to 0.5 mg/liter for clinical N. gonorrhoeae strains and related species. Cross-resistance with existing antimicrobial resistance was not detected, indicating that closthioamide could be used to treat drug-resistant N. gonorrhoeae.
PCR-based assays for the identification of Neisseria meningitidis serogroups 29E, X, and Z by detection of specific regions of the ctrA gene are described. The specificities of these assays were confirmed using serogroups A, B, C, 29E, H, W135, X, Y, and Z and nongroupable meningococcal isolates.

A glucose-negative group B strain of Neisseria meningitidis isolated from a meningitis case is described. A brief review of Neisseria identification procedures is also presented.
A fluorescence-based PCR method was developed, fully automated, and used to confirm infection with Neisseria meningitidis by detection of the meningococcus-specific ctrA gene. The method provided a highly sensitive, high-throughput assay that was reproducible and less labor-intensive than manual methods.
In a 12-month period, oxidase-positive, Gram-negative cocci showing similar characteristics in biochemical tests have been isolated from the urogenital tract of 39 male and female patients. Although these organisms superficially resemble Neisseria gonorrhoeae, biochemical characterization and the results of DNA base composition analysis indicate that they do not belong to the genus Neisseria. T...
