This Gram-stained specimen reveals N. gonorrhoeae intracellular diplococci, leading to a positive diagnosis of gonorrhea.
The genus Neisseria consists of aerobic, non-spore-forming Gram-negative coccobacilli, which inhabit the mucous membranes of humans. These microbes require a moist environ... Read More
