The family Neisseriaceae consists of gram-negative bacteria, primarily known for including the genera Neisseria and Kingella. These bacteria are often found in the human body, particularly in the mucous membranes of the respiratory and urogenital tracts. Some species, like Neisseria gonorrhoeae, are pathogenic and can cause diseases such as gonorrhea. Members of the Neisseriaceae family are characterized by their cocci shape and tendency to form pairs, resembling coffee beans. They are aerobic and require specific nutrients for growth, making them important in both clinical and environmental microbiology. Understanding this family helps in diagnosing and treating infections caused by its members.
