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. My greatest hobby is to teach and motivate other peoples to do whatever they wanna do in life. ⇒ It requires a moist environment with a 5 – 10% CO2 for the growth in the laboratory.
