Quick Answer: What Diagnostic Medium For Neisseria Gonorrhea Is Best For Tracking Antibiotic Resistance?


How do you confirm Neisseria gonorrhoeae?

A Definitive diagnosis of gonorrhea requires: isolation of N. gonorrhoeae from sites of exposure (e.g., urethra, endocervix, throat, rectum) by culture (usually a selective medium) and demonstrating typical colonial morphology, positive oxidase reaction, and typical gram-negative morphology and.

What selective media can be used for identification of N gonorrhoeae?

The catalase test (3% hydrogen peroxide) or superoxol (30% hydrogen peroxide) are other rapid tests used in the presumptive identification of N gonorrhoeae.

Which method has the best sensitivity and specificity for gonorrhea?

As with chlamydia, NAATs are now considered the gold standard for diagnosing gonorrhea. The USPSTF found that testing for gonorrhea using NAATs had a sensitivity ranging from 90 to 100 percent and a specificity greater than 97 percent.

How does gonorrhea become resistant to antibiotics?

The ceftriaxone- resistance mutations alter the bacterial enzyme that is the target of ceftriaxone, making it harder for the drug to bind to the enzyme but at the same time making it less able for the enzyme to build and repair bacterial cell walls.

Can Neisseria gonorrhoeae be cured?

Yes, gonorrhea can be cured with the right treatment. It is important that you take all of the medication your doctor prescribes to cure your infection. Medication for gonorrhea should not be shared with anyone. Although medication will stop the infection, it will not undo any permanent damage caused by the disease.

What antibiotics treat Neisseria gonorrhoeae?

Due to emerging strains of drug-resistant Neisseria gonorrhoeae, the Centers for Disease Control and Prevention recommends that uncomplicated gonorrhea be treated with the antibiotic ceftriaxone — given as an injection — with oral azithromycin (Zithromax).

What medium is best for growing gonorrhea?

Neisseria gonorrhoeae is one of the causatives of sexually transmitted diseases, and it is a fastidious organism. This organism is typically cultured using an agar medium such as chocolate agar plate (GCII agar base with 1% IsoVitaleX [BBL] and purified hemoglobin).

Is chocolate agar selective or differential?

Chocolate agar, a differential medium for gram-positive cocci.

What is the prevention of gonorrhea?

The surest way to avoid transmission of gonorrhea or other STDs is to abstain from vaginal, anal, and oral sex, or to be in a long-term mutually monogamous relationship with a partner who has been tested and is known to be uninfected.

What is the best test to detect gonorrhea?

Gonorrhea nucleic acid amplification (NAAT) testing: NAAT testing detects the genetic material (DNA) of the gonorrhea bacteria and is considered the optimal test for gonorrhea infection. This type of test can be performed on a urine sample or a swab taken from a site of potential infection.

What culture method is used for gonorrhea?

Specimens collected for gonorrhea culture should be obtained by using swabs with plastic or wire shafts and rayon, Dacron, or calcium alginate tips. Other swab material such as wood shafts and cotton tips might be inhibitory or toxic to the organism and should be avoided.

When can you not collect a gonorrhea culture?

Delay obtaining specimens until 2 hours after patient has last voided. 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).

What happens if antibiotics don’t work for gonorrhea?

When bacteria become resistant to an antibiotic, they no longer can be killed by that medicine. If you’ve been treated for gonorrhea and don’t get better, you may be retested to see if there is resistance to the antibiotic you took. In this case, you may need another antibiotic.

Is Super Gonorrhea antibiotic resistance?

Instead, super gonorrhea results when the bacteria that causes gonorrhea, Neisseria gonorrhoeae, develops a high level of resistance to the antibiotics normally used to treat the infection: azithromycin and ceftriaxone.

Can you develop gonorrhea resistance?

Immunity to N. gonorrhoeae is a topic that until recently has been hard to define, because there is currently no clearly established state of immunity to gonorrhea in humans, which are the only natural host for this infection.
