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.

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.

For example, when the genome of N. gonorrhoeae (strain FA1090) is compared to that of N. meningitidis (strain H44/76) 68% of their genes are shared. Neisseria - Wikipedia Neisseria species including Neisseria gonorrhoeae (which causes gonorrhea ), Streptococcus pneumoniae , and Haemophilus influenzae type B all release a protease that destroys IgA.

Neisseria gonorrhoeae グラム染色は、そんな抗菌薬選択の答えを導くことができる。グラム染色(Gram Stain)をマスターし Gram stain of urethral discharge with intracellular neisseria gonorrhoeae. Publication Date : August 2009 MyBook is a cheap paperback edition of the original book and will be sold at uniform, low price.

Gram negative diplococcus 2. Called GC as an abbreviation for Gonococcus. 3. The disease is gonorrhea ("The Gram Stain. ▫ isolate: pus smear. ▫ organism: Neisseria gonorrhoeae. ▫ reaction: Gram negative.

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.

Neisseria spp. are a Gram-negative non-spore-forming diplococcus that has a flattened shape; its size ranges between 0.6–0.8 μm. They are oxidase-positive, non-acid-fast cocci or plump rods. They can reach a diameter of around 0.6–0.8 μm and sometimes up to 1.0 × 2.0–3.0 μm.

Rates of recovery for N. gonorrhoeae can be significantly improved if specimen is received within 12 hours of collection. Gonorrhoea is a disease is due to infection with the bacteria Neisseria gonorrhoeae. The common sites of infection are the mucous membranes of the urethra, endocervix, rectum, pharynx and conjunctiva.

It is of no value in pharyngitis. Patients from whom N. gonorrhoeae is isolated are reported to the City of Chicago Board of Health. This is mandated by law. A Neisseria gonorrhoeae DNA probe assay is available for rapid detection of this pathogen.

Freshly isolated 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. Gram stain and culture have been the primary methods of diagnosing N. gonorrhoeae. Gram stain is quick and inexpensive with a high sensitivity and specificity for urethral specimens (sensitivity and specificity are both 90% to 95%), however, it is much lower for endocervical and rectal specimens with both the sensitivity and specificity ranging from 50% to 70%.

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.

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. A Neisseria gonorrhoeae Gram Stain. Gram negative diplococci (fastidious) Clinical Significance. This organism is associated with sexually transmitted infections including urethritis, epididymitis, orchitis, prostatitis, proctitis, cervicitis, salpingitis, pelvic inflammatory disease, Bartholin’s abscess, and pharyngitis. The Gram stain of a smear of urethral exudates or endocervical secretions shows typical Gram-negative, non-motile, intracellular diplococci.

neisseria gonorrhoeae gram stain. A 45-year-old member asked: can you get rid of neisseria gonorrhoeae? Dr. Gregory Lewis answered. 44 years experience Urology.

But they have some differences which are as follows: Neisseria gonorrhoeae é uma bactéria da família Neisseriaceae. É um diplococo gram-negativo, não flagelado, não formador de esporos, não hemolítico, aeróbio ou facultativamente anaeróbio que habita o trato respiratório superior do homem, sendo responsável pela gonorreia – doença sexualmente transmissível, com formato de rim – e consequentemente pela conjuntivite gonocócica Perform an oxidase test on growth of representative colonies that stained as ( gram- negative) diplococci. Because the oxidase reagent is toxic for bacteria, it is. Figure 1.

Obtain specimens for gram stain and gonorrhea culture first, BEFORE specimens for Chlamydia or Pap smear. 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.
