Staphylococcaceae

Staphylococcaceae, from Ancient Greek σταφυλή, meaning "bunch of grapes", and κόκκος, meaning "sphere", are a family of Gram-positive bacteria that includes the genus Staphylococcus, noted for encompassing several medically significant pathogens.
The five genera Jeotgalicoccus, Macrococcus, Nosocomiicoccus, Salinicoccus, and Staphylococcus have been shown to be monophyletic, while Gemella appears to be polyphyletic. The pathogen methicillin-resistant Staphylococcus aureus is a member of this family.
The most famous species in this family is Staphylococcus aureus, usually found in the skin microbiota. Staphylococcus aureus is the pathogenic bacteria with the highest global mortality in 2019, with approximatively 1.1 million deaths.

Phylogeny

The currently accepted taxonomy is based on the List of [Prokaryotic names with Standing in Nomenclature] and National Center for Biotechnology Information.
GTDB renames this taxon "Staphylococcales", as it finds that the evolutionary divergence within this taxon is more fitting of an order. Bello et al. puts the GTDB approach to familial division into a formal proposal, but the proposed names have yet to appear on any Validation List.
