Neisseria gonorrhoeae causes urogenital, rectal, and pharyngeal infections, as well as hyperacute conjunctivitis, and can invade intact corneal epithelium, induce keratolysis of the corneal stroma, and perforate the cornea. N gonorrhoeae is always a pathogen, whereas the closely related species Neisseria meningitidis may be commensal in the pharynx without causing disease. N gonorrhoeae is a bean-shaped, gram-negative diplococcus usually seen within neutrophils on a clinical smear taken from ocular or genital sites (Fig 10-2).
