Neisseria gonorrhoeae is the pathogenic bacterium that causes gonorrhea. Slides 1 through 9 show Neisseria gonorrhoeae present in a urethral or vaginal discharge stained with the Gram stain at 1000X magnification. The bacteria have been phagocytized by white blood cells (neutrophils). The nuclei of the white blood cells are the large red circles, while the bacteria are the small red circles that tend to be in pairs (diplococci). Neisseria gonorrhoeaeare thus identified as "Gram-negative intracellular diplococci". Slide 10 shows uninfected white blood cells stained with the Gram stain.
