Description:This Gram-stained photomicrograph revealed the presence of numerous Gram-negative Neisseria lactamica diplococcal bacteria.
N. lactamica strains are colistin-resistant, grow on gonococcal selective medium, and are characterized by their ability to produce acid from glucose, maltose, and lactose, and by their ability to produce beta-galactosidase. Among the Neisseria species, N. lactamica is the probably the easiest species to identify; it is the only species that produces acid from lactose and produces beta-galactosidase. Thus, with a rare exception (one known, unpublished report of a lactose-negative strain), this species should not be misidentified.”
