Introduction. Because investigations of sexual abuse may be initiated on the basis of a laboratory diagnosis of gonorrhea, it is important that only strains of N. gonorrhoeae be identified and reported as N. gonorrhoeae. Several Neisseria and related species may be misidentified as N. gonorrhoeae unless appropriate differential tests are performed. The purpose of this, and other, pages in this.
