Sphingobacterium multivorum is a Gram-negative, nonfermentative bacillus that rarely causes disease in humans. In the medical literature, only a few cases of infections caused by this organism have been reported. Almost all the reported cases of this infection were associated with conditions that decrease immunity.
Is flavobacterium motile?
Abstract. The Flavobacterium species are Gram-negative rods, non-spore-forming, strictly aerobic, motile by gliding, pigmented bacteria containing menaquinone-6 as the sole respiratory quinone.
Is Flavobacterium gram positive?
Flavobacterium species are nonfastidious, oxidase-positive, gram-negative rods that do not ferment glucose.
What is the only motile bacteria under Flavobacteriaceae?
Is Flavobacterium catalase positive or negative?
A yellow-pigmented, oxidase-positive, catalase-negative, Gram-stain-negative, rod-shaped, aerobic and non-motile bacterial strain designated K3R-10T was isolated from a freshwater source.
Does Flavobacterium grow on MacConkey Agar?
Clinical Flavobacterium meningosepticum and Group IIb. Primary plating of a clinical specimen is usually onto blood, chocolate, eosin-methylene blue, or MacConkey agar, but other media may be used. Incubation temperature is 35–37°C, but the bacteria will grow at room temperatures (20–25°C).
Is Flavobacterium pathogenic?
Most Flavobacterium are harmless, but some are opportunistic or true pathogens and cause disease in a wide variety of organisms, including plants, fish, and humans.
Is Bacteroides aerobic or anaerobic?
Bacteroides species are anaerobic, bile-resistant, non-spore-forming, gram-negative rods.
Is Flavobacterium motile or nonmotile?
Flavobacterium include a specific genus of gram-negative bacteria that are characterized by their presence in soil and fresh water environments. Flavobacterium can be either non-motile or motile and are rod-shaped.
Is flavobacterium catalase positive?
Is Elizabethkingia Meningoseptica motile?
Elizabethkingia meningoseptica is increasingly being recognized as a pathogen in hospitalized patients. It is a gram-negative, nonfermenting, nonmotile, oxidase positive bacilli growing on enriched media only.
How many species of Sphingobacterium are there in World?
Sphingobacterium spp. Two species of the genus Sphingobacterium, S. multivorum and S. spiritivorum, are derived from several Flavobacterium spp. and CDC groups IIk-2 and -3 (see Table 181-2). In addition, the genus also harbors S. antarcticum, S. faecium, S. thalpophilum and Sphingobacterium genospecies 1 and 2.
Is the Sphingobacterium multivorum a life threatening bacteria?
Sphingobacterium multivorum, a gram-negative bacillus, is ubiquitous in nature, and is rarely involved in human infections, however it is intrinsically resistant to many commonly employed antibiotics and can be a life threatening microorganism.
How is the genus Sphingobacterium different from Flavobacteria?
The genus Sphingobacterium includes organisms previously classified as Flavobacterium species. The organisms that were transferred to this genus contain large amounts of sphingophospholipid compounds in their cell membranes and have other taxonomic features that distinguish them from flavobacteria.
What kind of infection does s.multivorum have?
Most cases of S. multivorum infection are nosocomial, but the natural habitat of the organism is not well defined.
