Streptococcus parasanguinis is a Gram-positive, alpha-haemolytic coccus of the family Streptococcaceae, belonging to the mitis group of viridans streptococci. It is one of the early colonisers of the oral cavity and dental plaque, but can enter the bloodstream and cause infective endocarditis, particularly in individuals with predisposing cardiac conditions. Genomically, S. parasanguinis is naturally competent for transformation and carries fimbria-associated genes (fap1 and related loci) that mediate adhesion to saliva-coated surfaces and are important for biofilm initiation.

How to read this: A value outside a failure limit fails QC. Within the failure limits, values beyond a warning limit are borderline and worth a manual look; values within the warning limits pass that criterion. A dash means that no bound is defined on that side.
