Kingella kingae is a species of Gram-negative facultative anaerobic β-hemolytic coccobacilli. First isolated in 1960 by Elizabeth O. King , it was not recognized as a significant cause of infection in young children until the 1990s, when culture techniques had improved enough for it to be recognized.
Kingella is a genus of bacteria of the family Neisseriaceae. [1] It belongs to the HACEK group of fastidious Gram-negative bacteria that tend to cause endocarditis . [ 2 ] Kingella kingae is its type species .
Elizabethkingia meningoseptica is a Gram-negative, rod-shaped bacterium widely distributed in nature (e.g. fresh water, salt water, or soil). It may be normally present in fish and frogs; it may be isolated from chronic infectious states, as in the sputum of cystic fibrosis patients.
HACEK is an abbreviation of the initials of the genera of this group of bacteria: Haemophilus, Aggregatibacter (previously Actinobacillus), Cardiobacterium, Eikenella, Kingella. [1] The HACEK organisms are a normal part of the human microbiota , living in the oral - pharyngeal region.
In the 1960s, King identified a novel bacteria from human respiratory secretions, blood, and bone and joint exudates that was designated Moraxella kingii in her honor shortly after her death. In 1976 it was reassigned to the genus Kingella and given the species name Kingella kingae. [7] [8]
Elizabethkingia is a genus of bacterium in the order of Flavobacteriales.It was established in 2005 from a branch in of the genus Chryseobacterium, [1] and named after Elizabeth O. King, the discoverer of the type species. [2]
Most strains are gamma-hemolytic (non-hemolytic), but some also display alpha-hemolytic activity on sheep blood agar plates. Strep bovis is a non-enterococci.

Streak a beta-lysin–producing strain of aureus down the center of a sheep blood agar plate. The test organism streak should be 3 to 4 cm long. Streak test organisms across the plate perpendicular to the S. aureus streak within 2 mm. (Multiple organisms can be tested on a single plate). Incubate at 35°-37°C in ambient air for 18-24 hours.
