Staphylococcussuvun

Staphylococcussuvun is a hypothetical species within the genus Staphylococcus, used here as an example to illustrate bacterial taxonomy and clinical relevance. In this account, Staphylococcussuvun is described as a Gram-positive, non-motile bacterium that forms irregular cocci in clusters and is catalase-positive. Like other staphylococci, it is typically facultatively anaerobic and tolerates high salt concentrations.

Isolation and habitat: Type strains have been described from human skin and nares in urban environments; colonization is common but asymptomatic in most individuals. It has been described as coagulase-negative, which generally corresponds with lower virulence compared with coagulase-positive Staphylococcus aureus.

Biochemical and genetic characteristics: It ferments mannitol and demonstrates typical Staphylococcal biochemical tests. The genome is about 2.9–3.2 megabases with GC content around 32–34%, encoding genes for enzymes common to staphylococci, along with several lineage-defining 16S rRNA gene variations distinguishing it from related species.

Pathogenicity and clinical relevance: S. suvun has a relatively low virulence profile; it can be recovered from mild skin infections or device-associated colonization, but systemic disease is rare. Antimicrobial susceptibility is variable; some isolates harbor mecA-like elements conferring beta-lactam resistance, while others remain susceptible to beta-lactams and non-beta-lactam agents. Standard infection-control and antibiotic stewardship practices apply.

Taxonomy and history: The name combines the genus Staphylococcus with the epithet suvun, proposed in fictional taxonomic descriptions for teaching purposes. It illustrates how new species are differentiated by phenotype, genetics, and ecological niche. See also: Staphylococcus, Staphylococcaceae, coagulase-negative staphylococci.
