Cervicitis is caused by:a) Pseudomonusb) Staphylococcusc) Chlamydiad) Trichomonase) N. gonorrhoea
**Core Concept**
Cervicitis is an inflammation of the cervix, often caused by infectious agents. The most common pathogens responsible for cervicitis are sexually transmitted bacteria.
**Why the Correct Answer is Right**
Chlamydia trachomatis is a sexually transmitted bacterium that commonly causes cervicitis. The pathogen adheres to the cervical epithelial cells, leading to an inflammatory response. Chlamydia's mechanism involves the inclusion formation within the host cells, where it replicates and causes cell death. This results in the release of pro-inflammatory cytokines, leading to cervicitis.
**Why Each Wrong Option is Incorrect**
**Option A:** Pseudomonas is a type of bacteria that typically causes infections in immunocompromised individuals or those with pre-existing respiratory conditions, not cervicitis.
**Option B:** Staphylococcus is a type of bacterium that commonly causes skin and soft tissue infections, not cervicitis.
**Option D:** Trichomonas vaginalis is a protozoan parasite that causes vaginitis, not cervicitis.
**Clinical Pearl / High-Yield Fact**
Chlamydia trachomatis is the most common cause of cervicitis, and its diagnosis often requires nucleic acid amplification testing (NAAT) due to its fastidious nature.
**Correct Answer: C. Chlamydia**
