Rothia aeria (strain A1-17B), Rothia amarae (strain J18), Rothia dentocariosa (strain ATCC 17931), Rothia endophytica (strain YIM 67072), Rothia mucilaginosa (strain ATCC 25296), Rothia nasimurium (strain CCUG 35957), Rothia terrae (strain L-143) ^[2]

Description and significance

Give a general description of the species (e.g. where/when was it first discovered, where is it commonly found, has it been cultured, functional role, type of bacterium [Gram+/-], morphology, etc.) and explain why it is important to study this microorganism.

Type of bacterium: Gram - positive, non-sporogenic, non-motile

Morphology: Coccoid to rod-shaped. Younger colonies are round, convex, smooth or creamy and potentially resembling corynebacteria and staphylococci. Mature colonies may be raised and highly convoluted. ^[4]

First discovered:

Commonly found: Mouth and respiratory tract

Cultured: yes

Functional role:

Importance: Morphologically similar to Actinomyces and Nocardia genus, which contain pathogenic members. ^[3]

Genome structure

Select a strain for which genome information (e.g. size, plasmids, distinct genes, etc.) is available.

Strain: ATCC 17931 ^[5]

SIze: 2,506,025 bp

Motility:

Metabolic functions:

Reactions: catalase production, nitrate and nitrite reduction, esculin hydrolysis and acid production from glucose, sucrose, maltose, salicin and glycerol. ^[3]

Ecology

Aerobe/anaerobe, habitat (location in the oral cavity, potential other environments) and microbe/host interactions.

Aerobic ^[4]

Habitat: Oral cavity, other potential environments??

Microbe-host interactions:

Pathology

Do these microorganisms cause disease in the oral cavity or elsewhere?
