Is chlamydia eukaryotic or prokaryotic?

Can you see gonorrhea on Gram stain?

The presence of typical gram-negative intracellular diplococci and polymorphonuclear leukocytes on Gram stain from a specimen collected from a symptomatic male establishes a diagnosis of gonorrhea (sensitivity, >95%; specificity, >99%).

What are facts about Chlamydia?

Chlamydia Facts. Chlamydia is caused by the bacterium Chlamydia trachomatis. Chlamydia is sometimes called NGU or non-gonorrheal urethritis. Because it is caused by a bacterium, not a virus, chlamydia can be cured with a complete course of the correct antibiotics.
