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. 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?

Although V. parvula is generally considered to be a commensal or non-pathogenic resident in the bacterial communities of the oropharynx and the gastrointestinal, genitourinary and respiratory tracks [7], it known to be associated with a number of human oral diseases [5]. In particular is has been shown to have a strong association with severe early childhood caries and intraradicular infections [6]. Rarely, however, V. parvula can cause serious and life-threatening infections, including osteomyeltitis, spondylodiscitis, discitis, meningitis and sinus infections [7,8].

Application to biotechnology
