zopfii. Kurthia is a bacterial genus from the Planococcaceae family. Kurthia is a gram-positive, non-spore forming, rod-like bacteria. This strain has been isolated from diarrhea samples, however, no evidence has been brought forward suggesting it is pathogenic in nature.
Is Kurthia zopfii Gram-positive or negative?
zopfii is a motile, saprophytic, Gram-positive firmicute of regular, unbranched rods that fragment into a coccoid morphology in older cultures (1–4).
Is Kurthia Gram-positive?
The genus Kurthia is made up of Gram-positive, actively motile, biochemically inactive bacilli of the family Brevibacteriaceae. An isolate from a routine eye swab which produced a heavy, pure growth of a Kurthia species is described.
Does Kurthia ferment mannitol?
On this medium, Listeria spp. are entirely black on a red background, whereas resistant strains of enterococci and staphylococci are surrounded by a yellow zone due to mannitol fermentation. The medium surrounding resistant Kurthia strains turns maroon due to their strong alkaline reaction.
Is Kurthia aerobic?
Bacteria of the genus Kurthia are strictly aerobic, Gram-positive rods that do not produce acid from glucose.
Is Kurthia motile?
The genus Kurthia is made up of Gram-positive, actively motile, biochemically inactive bacilli of the family Brevibacteriaceae.
Does Kurthia form endospores?
One strain (TR-43) did not form endospores. Three genera (Planococcus, Lactobacillus, and Kurthia), which are similar to Bacillus except for endospore formation, were described in Bergey’s manual (Sheath et al. circulans which lacks the ability to form endospores.
Is Kurthia oxidase positive?
ORGANISMS of the Kurthia group are Gram-positive actively motile bacilli that are facultative anaerobes, catalase-positive and oxidase-negative. They are inactive biochemically, but some species liquefy gelatin and produce hydrogen sulfide.
Does Kurthia reduce nitrate?
Kurthia spp. give negative responses in most of the usual biochemical tests, e.g., indole, nitrate reduction; urease, lecithinase production; and hydrolysis of starch and esculin; however, some strains produce H2S weakly (Jones, 1975; Shaw and Keddie, 1983a).
