Gonococcus is a gram-negative diplococcus, catalase, and oxidase positive, fermenting only glucose. It causes the sexually transmitted genitourinary infection gonorrhea as well as other forms of gonococcal disease including disseminated gonococcemia, septic ahritis, and gonococcal ophthalmia neonatorum.
