<prompt> Please answer with one of the option in the bracket. Write reasoning in between . Write answer in between .Q:A 26-year-old man comes to the emergency department for evaluation of burning with urination and purulent urethral discharge for the past 3 days. He is sexually active with multiple female partners. Several months ago he was diagnosed with urethritis caused by gram-negative diplococci and received antibiotic treatment with complete resolution of his symptoms. A Gram stain of the patients urethral discharge shows gram-negative intracellular diplococci. Which of the following properties of the infecting organism most contributed to the pathogenesis of this patients recurrent infection?? A: Expression of beta-lactamase genes, B: Synthesis of capsular polysaccharides, C: Absence of immunogenic proteins, D: Production of enzymes that hydrolyze urea, E: Variation of expressed pilus proteins,  <response>: This is a question about the pathogenesis of recurrent urethritis caused by Neisseria gonorrhoeae in a patient with multiple sexual partners. The key information is that the patient was previously diagnosed and treated for urethritis caused by N. gonorrhoeae, but now has recurrence of symptoms and a positive Gram stain showing intracellular gram-negative diplococci, indicating N. gonorrhoeae infection again. The answer choices focus on various virulence factors and antigenic variation capabilities of N. gonorrhoeae that allow it to evade host defenses and cause recurrent infection. Choice A regarding beta-lactamase production may lead to antibiotic resistance but does not explain recurrence in an untreated infection. Choices B, C, and D do not explain the pathogenesis of recurrent infection in this case. Choice E regarding pilus variation is the most likely explanation for how N. gonorrhoeae was able to cause a new infection in this patient by altering its surface proteins to evade existing immune defenses.E: Variation of expressed pilus proteins
