Elizabethkingia meningoseptica is a Gram-negative, rod-shaped bacterium widely distributed in nature. 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. In 1959, American bacteriologist Elizabeth O. King was studying unclassified bacteria associated with pediatric meningitis at the Centers for Disease Control and Prevention in Atlanta, when she isolated an organism that she named Flavobacterium meningosepticum. In 1994, it was reclassified in the genus Chryseobacterium and renamed Chryseobacterium meningosepticum(chryseos = "golden" in Greek, so Chryseobacterium means a golden/yellow rod similar to Flavobacterium). In 2005, a 16S rRNA phylogenetic tree of Chryseobacteria showed that C. meningosepticum along with C. miricola were close to each other but outside the tree of the rest of the Chryseobacteria and were then placed in a new genus Elizabethkingia named after the original discoverer of F. meningosepticum.
Aggregatibacter actinomycetemcomitans is a Gram-negative, facultative anaerobe, nonmotile bacterium that is often found in association with localized aggressive periodontitis, a severe infection of the periodontium. It is also suspected to be involved in chronic periodontitis. Less frequently, A. actinomycetemcomitans is associated with nonoral infections such as endocarditis. Its role in aggressive periodontitis was first discovered by Danish-born periodontist Jørgen Slots, a professor of dentistry and microbiology at the University of Southern California School of Dentistry.
Chryseobacterium is a genus of Gram-negative bacteria. Chryseobacterium species are chemoorganotrophic, rod shape gram-negative bacteria. Chryseobacterium form typical yellow-orange color colonies due to flexirubin-type pigment. The genus contains more than 100 described species from diverse habitats, including freshwater sources, soil, marine fish, and human hosts.
Cupriavidus pauculus is a Gram-negative, nonfermentative, motile bacterium of the genus Cupriavidus and family Burkholderiaceae isolated from water from ultrafiltration systems and bottled mineral water. C. pauculus is associated with human infections.
Elizabethkingia anophelis is a yellow-pigmented, rod-shaped, gram-negative bacterium in the Flavobacteriaceae family. Elizabethkingia is isolated from the midgut of Anopheles gambiae G3 mosquitoes reared in captivity. The genus Elizabethkingia, named for former US Centers for Disease Control and Prevention (CDC) microbiologist Elizabeth O. King, also includes E. meningoseptica which causes neonatal sepsis and infections in immunocompromised persons, E. endophytica, and E. miricola.
Elizabeth Osborne King was an American microbiologist who discovered and described bacteria of medical importance at the United States Centers for Disease Control and Prevention from the late 1940s through the early 1960s. A 1984 CDC manual dedication referred to King as "internationally known as an authority on a variety of unusual bacteria." The genera Kingella and Elizabethkingia and several species of bacteria are named to honor her for her pioneering work. King died of cancer on April 8, 1966, in Atlanta, where she is interred in Oakland Cemetery.
Elizabethkingia endophytica is a slightly yellow Gram-stain-negative rod-shaped bacterial strain isolated from the stem of healthy 10-day-old sweet corn . A comparison of the 16S rRNA gene sequence of the isolate showed 99.1, 97.8, and 97.4% similarity to the 16S rRNA gene sequences of the type strains of Elizabethkingia anophelis, Elizabethkingia meningoseptica and Elizabethkingia miricola, respectively. DNA-DNA hybridization indicated that the strain is representative of a new species.
Elizabethkingia is a genus of bacterium described in 2005, named after Elizabeth O. King, the discoverer of the type species. Before this genus being formed in 2005, many of the species of Elizabethkingia were classified in the Chryseobacterium genus. Elizabethkingia has been found in soil, rivers, and reservoirs worldwide.
