Neisseria is a large genus of bacteria that colonize the mucosal surfaces of many animals. Of the 11 species that colonize humans, only two are pathogens, N. meningitidis and N. gonorrhoeae.
Neisseria species are Gram-negative bacteria included among the Pseudomonadota, a large group of Gram-negative forms. Neisseria diplococci resemble coffee beans when viewed microscopically.[1]
