DOC for Neisseria gonorrhea infection is
**Core Concept**
The question is testing the student's knowledge of the recommended treatment for Neisseria gonorrhea infection, a sexually transmitted bacterial infection caused by the bacterium Neisseria gonorrhoeae. The recommended treatment is a combination of antibiotics to prevent antibiotic resistance.
**Why the Correct Answer is Right**
The Centers for Disease Control and Prevention (CDC) recommend dual therapy with ceftriaxone (a third-generation cephalosporin antibiotic) and azithromycin (a macrolide antibiotic) as the first-line treatment for uncomplicated gonorrhea. Ceftriaxone works by inhibiting cell wall synthesis in the bacterial cell, ultimately leading to bacterial lysis and death. Azithromycin, on the other hand, inhibits protein synthesis by binding to the 50S ribosomal subunit of the bacterial cell.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because fluconazole is an antifungal medication used to treat fungal infections, not bacterial infections like gonorrhea.
**Option B:** This option is incorrect because metronidazole is an antibiotic used to treat various bacterial and protozoal infections, but it is not the recommended treatment for gonorrhea.
**Option C:** This option is incorrect because ciprofloxacin is a fluoroquinolone antibiotic that was previously used to treat gonorrhea, but due to widespread resistance, it is no longer recommended as a first-line treatment.
**Clinical Pearl / High-Yield Fact**
It's essential to remember that the recommended treatment for gonorrhea is subject to change due to emerging antibiotic resistance. Always consult the latest CDC guidelines for the most up-to-date treatment recommendations.
**Correct Answer: D. Ceftriaxone and azithromycin.**
