**Question:** Most common cause of acute cervicitis is

A. Chlamydia trachomatis
B. Neisseria gonorrhoeae
C. Trichomonas vaginalis
D. Human papillomavirus (HPV)

**Correct Answer:** B. Neisseria gonorrhoeae

**Core Concept:** Acute cervicitis is inflammation of the cervix, typically caused by bacterial infections. The most common pathogens associated with cervicitis include Chlamydia trachomatis, Neisseria gonorrhoeae, Trichomonas vaginalis, and Human papillomavirus (HPV).

**Why the Correct Answer is Right:** Neisseria gonorrhoeae is a Gram-negative bacterium and a sexually transmitted infection (STI) that causes cervicitis. The bacterium invades the cervical mucosa and endocervical canal, leading to local inflammation and pain. Gonorrhea is often associated with other STIs, such as Chlamydia trachomatis, increasing the severity and duration of cervicitis symptoms.

**Why Each Wrong Option is Incorrect:**

A. Chlamydia trachomatis: Chlamydia is a common cause of cervicitis but is usually presented with urethritis or cervicitis in conjunction with Neisseria gonorrhoeae.

C. Trichomonas vaginalis: Trichomoniasis is a separate infection caused by Trichomonas vaginalis, which primarily affects the vagina and cervix. The correct answer is Trichomonas vaginalis for cervicitis caused by this microorganism.

D. Human papillomavirus (HPV): HPV is responsible for cervical cancer and genital warts but is not typically associated with acute cervicitis.

**Clinical Pearl:** Regular sexual health check-ups, including STI screening, are essential for early detection and appropriate treatment of cervicitis and other STIs. Early intervention can prevent severe complications and transmission to partners.
