ID#:14854
Description:Taken from a cervical smear specimen, this Gram-stained photomicrograph reveals the presence of “deceptive” extracellular diplococcal bacteria. Of importance, a bacterial culture returned a negative result.

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.
Laboratory criteria for diagnosis:

- Isolation of typical gram-negative, oxidase-positive diplococci (presumptive Neisseria gonorrhoeae) from a clinical specimen, or

- Demonstration of N. gonorrhoeae in a clinical specimen by detection of antigen or nucleic acid, or

- Observation of gram-negative intracellular diplococci in a urethral smear obtained from a male
