The Gram stain of a smear of urethral exudates or endocervical secretions shows typical Gram-negative, non-motile, intracellular diplococci. D. Culture The current preferred laboratory method for the diagnosis of N. gonorrhoeae infections is the isolation and identification of the agent.

If urine NAAT is NOT available, recommend Gram Stain and urethral GC Note: All GC cultures presumptively identified as Neisseria gonorrhoeae must be.

N. cinerea colonies are slightly more pigmented after incubation for 48 h. A direct smear for Gram staining may be performed as soon as the swab specimen is collected from the urethra, cervix, vagina or rectum. The Gram stain of a smear of urethral exudates or endocervical secretions shows typical Gram-negative, non-motile, intracellular diplococci. Gonorrhea cultures are incubated for a minimum of 48-72 hours. Growth on MTM is screened for presumptive positives by oxidase test and gram stain. Positive cultures are confirmed by biochemical identification. Neisseria gonorrhoeae is a Gram-negative coccus, 0.6 to 1.0 µm in diameter, usually seen in pairs with adjacent flattened sides (Figure 1 Left and Fig 2 below).

Neisseria meningitidis colonies on chocolate agar plate. Figure 3. Gram stain of spun CSF showing N. meningitidis diplococci.

N. gonorrhoeae direct Gram Stain of symptomatic male = urethral discharge= Intracellular GNDC is considered _ = appearance of GNDC inside Polymorph nuclear leukocyte presumptive N. gonorrhoeae direct Gram of females is only _: Normal vaginal and rectal flora include Gram neg coccobacilli that may resemble Neisseria spp. 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.

Moraxella catarrhalis and Neisseria meningitidis can be confused with N. gonorrhoeae on Gram stain. 50–53 Diagnosis of gonococcal ophthalmia is confirmed by culture on chocolate agar or Thayer–Martin media incubated at 37°C in humidified carbon dioxide. Appropriate culture specimens should also be obtained from the mother.

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.

Using DNA hybridization, N. cinerea exhibits 50% similarity to Neisseria gonorrhoeae. Gram stain of the isolates showed that 31.4 percent of the oxidase-positive isolates were gram-negative diplococci, 59 percent were yeastlike mole, and 9.7 percent were gram-negative bacilli. All of the gram-negative diplococci were confirmed to be N gonorrhoeae by sugar fermentation studies.

N. gonorrhoeae culture was performed when gram-negative diplococci were present in a gram-stained smear or with material collected at a return visit when the

Dr. Gregory Lewis answered. 44 years experience Urology. Neisseria gonorrhoeae (gonokocker) tillhör släktet Neisseria och är bakterien som orsakar den sexuellt överförbara sjukdomen gonorré.Bakterien uppträder endast hos människan och är en av de vanligast förekommande könssjukdomarna i världen. [1] Gram stain and culture have been the primary methods of diagnosing N. gonorrhoeae.

In liquid culture media like peptone water and TS broth, the growth of the bacterium occurs as Granular turbidity in the broth medium which is further analyzed for the morphology (under the microscope), gram reaction, biochemical tests, and Neisseria gonorrhoeae specific tests.

Neisseria gonorrhoeae is a Gram-negative, oxidase-positive, non-motile, non-sporulating, non-capsulate, diplococcus found asymptomatically in humans. N. gonorrhoeae is found in the family Neisseriaceae and genus Neisseria which contains two important human pathogens viz: N. gonorrhoeae and N. meningitidis.

Neisseria gonorrhoeae and Neisseria meningitidis are both Gram Negative Bacteria. They are diplococci, non-sporing, non-motile and oxidase positive. But they have some differences which are as follows:

Neisseria gonorrhoeae is a Gram-negative coccus, 0.6 to 1.0 µm in diameter, usually seen in pairs with adjacent flattened sides (Figure 1 Left and Fig 2 below). The organism is frequently found intracellularly in polymorphonuclear leukocytes (neutrophils) of the gonorrhea pustular exudate (Figure 1 Right). Moraxella catarrhalis and Neisseria meningitidis can be confused with N. gonorrhoeae on Gram stain. 50–53 Diagnosis of gonococcal ophthalmia is confirmed by culture on chocolate agar or Thayer–Martin media incubated at 37°C in humidified carbon dioxide. Appropriate culture specimens should also be obtained from the mother. 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.

Culture characteristics Neisseria gonorrhoeae| 65 A presumptive diagnosis ofN. gonorrhoeae originally isolated on selective medium can be made based upon colonial morphology, the observation of typical (gram-negative) diplococci in pairs, tetrads or clusters upon Gram stain or simple single stain with Loeffler’s methylene blue, and a positive oxidase reaction.
