Is Kurthia oxidase positive?

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.

Where is Kurthia found?

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. It has also been found in various meats, milks, and soils.

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).

Does Kurthia form endospores?

Based on these observations, the isolated spore-forming bacteria could be identified as B. circulans complex. 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.

Is arthrobacter catalase positive?

The genus Arthrobacter includes a heterogeneous group of aerobic, gram-positive, catalase-positive, nonfermentative coryneform bacteria of high G+C DNA content (18).

Is Arthrobacter catalase-positive or negative?

What is Kurthia Zopfii?

K. zopfii is a motile, saprophytic, Gram-positive firmicute of regular, unbranched rods that fragment into a coccoid morphology in older cultures (1–4). The type strain of K. The type strain of K. zopfii, ATCC 33403 (Kurth 1883) Trevisan 1885, was ordered (ATCC, Manassas, VA, USA) and rehydrated.

What is Gram cocci positive?

Gram-positive cocci include Staphylococcus (catalase-positive), which grows clusters, and Streptococcus (catalase-negative), which grows in chains. The staphylococci further subdivide into coagulase-positive (S. aureus) and coagulase-negative (S. epidermidis and S.

Where is Arthrobacter found?

soils
Abstract. Arthrobacter is a genus of obligate aerobes bacteria characterized by a rod–coccus growth cycle. Arthrobacter spp. commonly are found in soils, aerial surface of plants, and wastewater sediments; they do not form endospores and are highly proteolytic.

What is Kurthia used for?

Amino acids, alcohols, fatty acids are used as carbon sources. Kurthia species are widely distributed in the environment and are common in feces of farm animals, milk, soil and surface waters, meat and meat products after cold storage. Kurthia species are primarily non-pathogenic.

What are the carbon sources of Kurthia?

Amino acids, alcohols, fatty acids are used as carbon sources. Kurthia species are widely distributed in the environment and are common in feces of farm animals, milk, soil and surface waters, meat and meat products after cold storage.

Is Kurthia a pathogen?

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. It has also been found in various meats, milks, and soils.

What are the enzymes produced by Kurthia?

Kurthia species produce carbamoylase and hydantoinase. They also can produce L-Proline from glutamic acid or aspartic acid with the aid of a detergent. ^ a b c d e f g h i “Kurthia”.
