The genus Kingella includes 3 species, a typical species of K. Kingae. Cells are coccoid or short sticks with rectangular ends, 0.5-0.8 microns in size, i.e., smaller than most Moraxelles. Kinglets form blood colonies with a size of 1.0-2.0 mm after 48 h on blood agar, sometimes they have a mucous consistence. On the blood agar form a narrow zone of beta-hemolysis, but no "hemolysis" occurs on the "chocolate" agar. At room temperature, cultures on blood agar are very poorly preserved. The folded serum is not liquefied. Some kinella restore nitrates to nitrites.
These bacteria do not form urease, catalase and phenylalanine deaminase. Demanding to nutrient media, but the addition of growth serum does not improve. Ferment with acid formation of glucose and maltose, but not sucrose on medium containing ascitic fluid. The content of G + C in DNA is about 44-46 mol%. Highly sensitive to penicillin. The most often isolated from pharyngeal mucus, as well as from the mucous membranes of the urinary tract, nose, abscesses, bone injuries, joint disease, etc. The main habitat is the mucous membrane of the pharynx. Pathogenicity for a person it turns out.
