Neisseria sicca has the ability to produce acid from carbohydrates in which most of the strains not pigmented and forms dry wrinkled adherent colonies. It consists of multiple strains in which some reported to caused septicemia to an immunocompromised individual. It has been identified among Neisseria species to show O-repeat structure in its lipopolysaccharides.
Neisseria sicca is a natural inhabitant of the oropharynx in human that is known to be a harmless saprophyte but rarely considered as an etiologic agent in human disease particularly to those with immunodeficient individual. Some cases this bacterium caused serious infections includes endocarditis, bacteremia, meningitis and septic arthritis as well as peritonitis.
Neisseria sicca has the ability to degrade hydrogen peroxide in salivary sediment and dental plaques. It does not utilize lactose but produces acid from maltose, glucose, fructose and sucrose.
