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.

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. 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.

CONTAINS TWO IMPORTANT PATHOGENS Nesseria meningitidis Nesseria gonorrhoeae 5. 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.

Freshly isolated strains of N. gonorrhoeae exhibit at least two of four colony forms, designated T1, T2, T3, and T4. T1 colonies predominate in the first culture of an isolate; in subsequent subcultures, T3 colonies predominate and T1 colonies may not be observed. Neisseria gonorrhoeae, also known as gonococcus (singular), or gonococci (plural) is a species of Gram-negative diplococci bacteria isolated by Albert Neisser in 1879.

N. cinerea strains produce colonies that resemble those of N. gonorrhoeae in size and general appearance. 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.
