Is Flavobacterium a bacteria?
Bacteria known generically as flavobacterium (Phylum Bacteroidetes, Class Flavobacteriia, family Flavobactereaceae) are well known for their ubiquitous distribution in nature, metabolic diversity, and in some cases pathogenicity in animals, particularly fish.
How do you get Elizabethkingia Meningoseptica?
Elizabethkingia meningoseptica, a ubiquitous gram-negative aerobic bacillus, is an emerging hospital acquired pathogen in patients on dialysis. It has been isolated in the hospital environment in water supplies, disinfectants, and medical devices.

Where is Flavobacterium found?
Members of the genus Flavobacterium are distributed widely in nature and have been isolated from various habitats such as diseased fish, microbial mats, freshwater and river sediments, seawater and marine sediments, soil, glaciers, and Antarctic lakes.
Is Elizabethkingia motile?
Elizabethkingia species are gram negative bacilli which are aerobic, oxidase positive, indole positive, non-motile bacilli and does not ferment glucose. They can be found commonly in freshwater, saltwater, soil and in hospital environments (1).
How is Elizabethkingia transmitted?
This isn’t entirely surprising, Chen said, considering researchers don’t know exactly how Elizabethkingia anophelis is transmitted. But they suspect people get sick by coming into contact with the bacteria in hospitals or through contaminated water.
What kind of rod is flavobacterium meningosepticum?
Flavobacterium is a gram-negative, aerobic rod that is found in both soil and water. The organism is pigmented yellowish orange. Flavobacterium meningosepticum and F. indologenes have caused disease in leopard frogs, and F. meningosepticum and F. oderans disease outbreaks have been identified in Xenopus laevis colonies ( Green et al., 1999 ). ii.
What kind of disease is caused by Flavobacterium?
Flavobacterium meningosepticum and F. indologenes have caused disease in leopard frogs, and F. meningosepticum and F. oderans disease outbreaks have been identified in Xenopus laevis colonies ( Green et al., 1999 ). ii. Epizootiology and transmission.
How big are the colonies of Flavobacterium?
The colonies are typically translucent and pigmented yellow to orange. Usually 1-2 micrometers in diameter, they are convex or low convex, smooth and shiny with entire edges. Non-pigmented and occasionally opaque strains occur. Aerobic, having a strictly respiratory type of metabolism. Chemoorganotrophic.
Is the genus Flavobacterium sensitive to salts?
The genus Flavobacterium is physiologically diverse: It can be psychrophilic, psychrotolerant, or mesophilic, as well as halophilic, halotolerant, or sensitive to salts.
