Classification

Higher order taxa

Bacteria – Proteobacteria – Betaproteobacteria – Neisseriales – Neisseriaceae – Kingella

Species

Kingella oralis

Strain: strain UB-38 = ATCC 51147 = CCUG 30450 = CIP 103803.[1]

Description and significance

Kingella oralis is a gram-negative, bacilli bacteria that was first observed by Chen et al in 1989, who were investigating the presence of Eikenella corrodens in the human oral cavity.[2] This isolate was further investigated by Dewhirst et al in 1993, using Eikenella corrodens-selective medium containing 1 μg of clindamycin per ml. [3] Several characteristics distinguished the two species from each other including colony morphology on agar and acid production from sugars.

Kingella oralis is found in both supragingival and subgingival plaque, as well as in mucosa and saliva.[2]

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. Examples of citations [1], [2]

Genome structure

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

Cell structure and metabolism

Cell wall, biofilm formation, motility, metabolic functions.

Ecology

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

Pathology

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

Application to biotechnology

Bioengineering, biotechnologically relevant enzyme/compound production, drug targets,…

Current research

Summarise some of the most recent discoveries regarding this species.
