Family of bacteria

Staphylococcaceae Staphylococcus aureus Scientific classification Domain: Bacteria Kingdom: Bacillati Phylum: Bacillota Class: Bacilli Order: Bacillales Family: Staphylococcaceae Akatov et al. 1988 ex Schleifer and Bell 2010[1] Genera[1] See text Synonyms Staphylococceae Prévot 1940

**Staphylococcaceae**, from [Ancient Greek](/source/Ancient_Greek) σταφυλή (*staphulḗ*), meaning "bunch of grapes", and κόκκος (*kókkos*), meaning "sphere", are a [family](/source/Family_(taxonomy)) of [Gram-positive](/source/Gram-positive) [bacteria](/source/Bacteria) that includes the [genus](/source/Genus) *[Staphylococcus](/source/Staphylococcus)*, noted for encompassing several medically significant [pathogens](/source/Pathogens).

The five genera *[Jeotgalicoccus](/source/Jeotgalicoccus)*, *[Macrococcus](/source/Macrococcus)*, *[Nosocomiicoccus](/source/Nosocomiicoccus)*, *[Salinicoccus](/source/Salinicoccus)*, and *Staphylococcus* have been shown to be [monophyletic](/source/Monophyly), while *[Gemella](/source/Gemella)* appears to be [polyphyletic](/source/Polyphyly). The pathogen [methicillin-resistant *Staphylococcus aureus*](/source/Methicillin-resistant_Staphylococcus_aureus) is a member of this family.

The most famous species in this family is *[Staphylococcus aureus](/source/Staphylococcus_aureus)*, usually found in the skin [microbiota](/source/Microbiota). *Staphylococcus aureus* is the [pathogenic bacteria](/source/Pathogenic_bacteria) with the highest global mortality in 2019, with approximatively 1.1 million deaths.[2]

## Phylogeny

The currently accepted taxonomy is based on the [List of Prokaryotic names with Standing in Nomenclature](/source/List_of_Prokaryotic_names_with_Standing_in_Nomenclature) (LPSN)[1] and [National Center for Biotechnology Information](/source/National_Center_for_Biotechnology_Information) (NCBI).[3]

GTDB (below) renames this taxon "Staphylococcales", as it finds that the evolutionary divergence within this taxon is more fitting of an order. Bello et al. (2023) puts the GTDB approach to familial division into a formal proposal, but the proposed names have yet to appear on any [Validation List](/source/Validation_List).[4]
