Is Flavobacterium Gram positive or negative?
Is Flavobacterium Gram positive or negative?
Flavobacterium species are nonfastidious, oxidase-positive, gram-negative rods that do not ferment glucose.
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 Flavobacterium a pathogen?
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.
What is Myroides SPP?
Background. The Myroides spp., which were previously classified as Flavobacterium spp., are Gram negative, non-fermentative and non-motile bacteria. They do not traditionally belong to the normal human flora. Myroides genus includes two species: Myroides odoratus and Myroides odoratimimus [1].
Is flavobacterium aerobic or anaerobic?
a genus of gram-negative, aerobic or facultatively anaerobic, rod-shaped bacteria, characteristically producing a yellow pigment. Organisms occur widely in soil and water and are opportunistic pathogens in humans. F.
Is flavobacterium citrate positive?
They are catalase-positive, oxidase-positive, and citrate negative.

Is flavobacterium capsulatum pathogenic?
They are largely non-pathogenic, and do not survive long on the human skin surface.
Is flavobacterium motile?
Flavobacterium is a genus of Gram-negative, nonmotile and motile, rod-shaped bacteria that consists of 130 recognized species.
What is Empedobacter brevis?
Empedobacter brevis previously known with name of Flavobacterium breve belongs to Flavobacteriaceae family. It is an environmental, gram-negative bacteria and is rarely encountered in human specimens. The pathogenicity of the bacteria is rare and is usually limited to health care workers [1].
Is flavobacterium catalase positive?
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.
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.
What is Flavobacterium spp?
Flavobacterium spp. have been isolated from many chilled foods. They occur in significant numbers in many types of fresh and frozen fish species including halibut, sole cod, salmon and trout and seem to be particularly significant in milk and dairy products ( García-López et al., 2000a ).
What kind of bacteria is in a cat’s urine?
In a study published in the Journal of American Veterinary Association the following bacteria were found in the urine of clinically normal cats: Escherichia coli (E. coli), Staphylococcus spp, Streptococcus spp, Cornebacterium spp, Pasteurella spp and Flavobacterium spp.
What determines the infectivity of Gram-negative rods?
We studied the heat resistance and the range of growth temperature o gram-negative rods to find one of the bacterial factors governing their infectivity in exogenous and endogenous infections in predisposed patients. Escherichia coli, Klebsiella pneumoniae, serratia marcescens, Pseudomonas aeruginos …
