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.
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. [2]
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 .
Colonial morphology serves as the first step in the identification of microbial species from clinical samples. [10] Based on the visual appearance of the colonies, microbiologists can narrow down the list of possible organisms, allowing them to select appropriate tests to provide a definitive diagnosis.
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]
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]
Streptolysin O is an oxygen-sensitive cytotoxin secreted by most Group A streptococcus (GAS) and Streptococcus dysgalactiae; it interacts with cholesterol in the membrane of eukaryotic cells (mainly red and white blood cells, macrophages, and platelets), usually resulting in β-hemolysis under the surface of blood agar. Streptolysin S is an ...
