No evidence of N gonorrhoeae infection by culture, gram stain of a smear of the discharge, or antigen or nucleic acid detection. Urethritis should be documented.
Gently insert the urogenital swab into the urethra (women 1-2 cm, men 2-4 cm). Rotate the swab in one direction for at least one revolution for a minimum of 10 seconds. Withdraw the swab and inoculate MTM plate as described below. Moraxella catarrhalis and Neisseria meningitidis can be confused with N. gonorrhoeae on Gram stain.

D. Culture The current preferred laboratory method for the diagnosis of N. gonorrhoeae infections is the isolation and identification of the agent. Identification of Neisseria meningitidis. Once isolated, N. meningitidis, like N. gonorrhoeae discussed above, is identified by the oxidase test, Gram staining, and carbohydrate utilization reactions. N. meningitidis, like all neisseriae, is oxidase-positive and appears in a Gram stain as Gram-negative diplococci. neisseria gonorrhoeae gram stain. A 45-year-old member asked: can you get rid of neisseria gonorrhoeae?

Urinalysis is positive for leukocyte esterase and a Gram stain shows intracellular diplococci within polymorphonuclear neutrophils. Introduction: Classification Neisseria.
A photomicrograph of Neisseria gonorrhoeae viewed using a Gram-stain technique, 1979. This photomicrograph of N. gonorrhoeae, a gonococcus, is from a urethral discharge specimen in a case of acute
Gram stain Cell Morphology: of Neisseria spp. isolated on selective media for N. gonorrhoeae, isolates of other Neisseria spp. are gamma-glutamylaminopeptidase Neisseria gonorrhoeae gram staining of a preparation of urethral secretion showing coffee-bean-shaped diplococci, grouped within a granulocyte Neisseria gonorrhoeae Diagnosis Gram stain using methylene blue Among the Neisseria gonorrhoeae positive patients 27.57% were positive from Gram stain, 26.49% were culture positive, 30.27% were positive by PCR (p<0.001). 32.65% of the Neisseria gonorrhoeae isolates were penicillinase producers and 83.67% were susceptible to ceftriaxone.
We compared a simple, one-step staining procedure using a mixture of methylene blue and gentian violet to Gram stain for the detection of gonococcal urethritis. The sensitivity and specificity of both Gram stain and methylene blue/gentian violet stain were 97.3% and 99.6%, respectively.

Gram stain for Neisseria gonorrhoeae is a quick and inexpensive test that works by detecting Gram-negative diplococci (the gonorrhoea bacteria) under a microscope. The presence of bacteria resembling Neisseria gonnorhoeae in a man is diagnostic of gonnorhoea, however in women it is more difficult to diagnose, having a mixture of bacterial organisms present.
