Which statement regarding chlamydia infection is correct?
Correct Answer: C
Rationale: The correct statement regarding chlamydia infection is that the clinical manifestations include dysuria and urethral itching in males. Chlamydia is a sexually transmitted infection caused by the bacterium Chlamydia trachomatis. In males, common symptoms include a burning sensation during urination (dysuria) and urethral itching. It is important to note that chlamydia is often asymptomatic, especially in women, which is why regular screening is important to detect and treat the infection early. Option A is incorrect because the treatment of choice for chlamydia is typically antibiotics such as azithromycin or doxycycline, not oral penicillin. Option B is incorrect because nystatin or miconazole are used to treat fungal infections, not chlamydia. Option D is incorrect because small, painful vesicles on genital areas are more indicative of herpes simplex virus infection rather than chlamydia
