The organism that causes gonorrhea is best described as?

Explanation:
Gonorrhea is caused by Neisseria gonorrhoeae, a gram-negative diplococcus that is oxidase positive and grows on selective media such as Thayer-Martin. In clinical specimens, it often appears inside neutrophils as coffee-bean–shaped diplococci. Lab tests can distinguish it by glucose fermentation (it ferments glucose but not maltose), setting it apart from other Neisseria species. The other organisms listed cause different sexually transmitted infections: Chlamydia trachomatis is an obligate intracellular bacterium associated with nongonococcal urethritis and PID; Treponema pallidum is a spirochete causing syphilis; Haemophilus ducreyi causes chancroid.
