History

This species was described in 2003. [1]

Description

The cells are coccoid, Gram positive, catalase positive, oxidase positive with a diameter is 0·89–1·21 micrometres. Colonies reach 2–4 millimeters in diameter on P agar after 24 hours. Colonies are circular, smooth and glossy, without pigment. Growth is detected under anaerobic conditions at 15–36 °C and in 4% sodium chloride but not at 4 or 42 °C.

The G+C content of the DNA is 41–42 mol%.

It hydrolyses casein and gelatin but not Tween 80, starch, lecithin, aesculin or tyrosine. Alkaline and acid phosphatases are produced, nitrates are reduced. Acetoin, clumping factor and coagulase are not produced and activities of urease, haemolysis, arginine dihydrolase, arginine arylamidase, ornithine decarboxylase, beta-galactosidase, beta-glucuronidase, pyrrolidonyl arylamidase, esterase (C4), lipase (C14), Naphthol-AS-BI-phosphohydrolase, valine arylamidase, cystine arylamidase, alpha-galactosidase, N-acetyl-beta-glucosaminidase, alpha-mannosidase, alpha-fucosidase and esterase-lipase (C8) are negative.

Acid is produced from D-fructose, D-glucose, maltose, D-mannitol and D-trehalose. Acid is not produced from arabinose, N-acetylglucosamine, D-cellobiose, D-galactose, or methyl alpha-D-glucoside, lactose, D-mannose, D-melibiose, melezitose, raffinose, ribose, D-salicin, D-sorbitol, sucrose, turanose, xylitol and xylose.

It is resistant to novobiocin. Predominant fatty acids are iso-13 : 0, iso-15 : 0, anteiso-15:0, 16:1-omega-11c, iso-17:1-omega-10c and 18:1-omega-9c.

Epidemiology

This species was isolated from the skin of llamas ( Lama glama ).

Clinical

This species has not been associated with disease.

Corynebacterium is a genus of bacteria that are Gram-positive and aerobic. They are bacilli (rod-shaped), and in some phases of life they are, more particularly, club-shaped, which inspired the genus name.

Mycobacterium brisbanense is a member of the Mycobacterium fortuitum third biovariant complex. They are rapidly growing ubiquitous environmental organisms that normally inhabit soil, dust and water. These organisms frequently are human pathogens that cause a wide spectrum of clinically significant disease. It is important for practitioners to be aware of these organisms as possible etiological agents, as they are resistant to most first-line anti-tuberculous agents.

Cutinase

Cronobacter is a genus of Gram-negative, facultatively anaerobic, oxidase-negative, catalase-positive, rod-shaped bacteria of the family Enterobacteriaceae. They are generally motile, reduce nitrate, use citrate, hydrolyze esculin and arginine, and are positive for L-ornithine decarboxylation. Acid is produced from D-glucose, D-sucrose, D-raffinose, D-melibiose, D-cellobiose, D-mannitol, D-mannose, L-rhamnose, L-arabinose, D-trehalose, galacturonate and D-maltose. Cronobacter spp. are also generally positive for acetoin production and negative for the methyl red test, indicating 2,3-butanediol rather than mixed acid fermentation. The type species of the genus Cronobacter is Cronobacter sakazakii comb. nov.

<i>Pseudogymnoascus destructans</i>

Pseudogymnoascus destructans is a psychrophilic (cold-loving) fungus that causes white-nose syndrome (WNS), a fatal disease that has devastated bat populations in parts of the United States and Canada. Unlike species of Geomyces, P. destructans forms asymmetrically curved conidia. Pseudogymnoascus destructans grows very slowly on artificial media and cannot grow at temperatures above 20 °C. It can grow around 4 °C to 20 °C, which encompasses the temperatures found in winter bat hibernacula. Phylogenic evaluation has revealed this organism should be reclassified under the family Pseudeurotiaceae, changing its name to Pseudogymnoascus destructans.

Paenibacillus tylopili is a soil-dwelling, Gram-positive, rod-shaped bacterium. Described as new to science in 2008, it was found in the mycorhizosphere of the bolete fungus Tylopilus felleus.

Parasutterella is a genus of Gram-negative, circular/rod-shaped, obligate anaerobic, non-spore forming bacteria from the Proteobacteria phylum, Betaproteobacteria class and the family Sutterellaceae. Previously, this genus was considered "unculturable," meaning that it could not be characterized through conventional laboratory techniques, such as grow in culture due its unique requirements of anaerobic environment. The genus was initially discovered through 16S rRNA sequencing and bioinformatics analysis. By analyzing the sequence similarity, Parasutterella was determined to be related most closely to the genus Sutterella and previously classified in the family Alcaligenaceae.

<i>Arthrobacter bussei</i> Species of bacterium

Arthrobacter bussei is a pink-coloured, aerobic, coccus-shaped, Gram-stain-positive, oxidase-positive and catalase-positive bacterium isolated from cheese made of cow´s milk. A. bussei is non-motile and does not form spores. Rod–coccus life cycle is not observed. Cells are 1.1–1.5 µm in diameter. On trypticase soy agar it forms pink-coloured, raised and round colonies, which are 1.0 mm in diameter after 5 days at 30 °C The genome of the strain A. bussei KR32T has been fully sequenced.
