APEA Predictor Practice Exam

Urethritis is often caused by sexually transmitted infections, and the most commonly associated bacteria with this condition is Chlamydia trachomatis. This organism is a leading cause of urethritis, particularly in sexually active individuals. It often does not present with symptoms, which can lead to increased rates of transmission and complications if left untreated.

While Neisseria gonorrhea is also known to cause urethritis and can lead to similar symptoms, Chlamydia trachomatis is more prevalent in the general population. Other bacterial infections such as those caused by Escherichia coli typically relate to urinary tract infections rather than urethritis alone. Mycoplasma genitalium is emerging as a relevant pathogen in urethritis, but it is not as widely recognized as Chlamydia for this specific condition.

Therefore, when considering the most commonly associated bacteria with urethritis, Chlamydia trachomatis is the correct choice due to its higher incidence in the population and significant role in sexually transmitted infections.
