The genus was created in 1998.<ref name="Kloo1998">Kloos, W. E., D. N. Ballard, C. G. George, J. A. Webster, R. J. Hubner, W. Ludwig, K. H. Schleifer, F. Fiedler, and K. Schubert. 1998.

Int. J. Syst. Bacteriol. 48:859-877</ref>
==History== The first recognised species in this genus (''Macrococcus caseolyticus'') was initially named ''Micrococcus caseolyticus'' by Evans in 1916. It was then renamed ''Staphylococcus caseolyticus'' by Schleifer ''et al'' in 1982. It received its current designation in 1998 by Kloos ''et al''.
==Description== Members of the genus ''Macrococcus'' are Gram-positive, nonmotile, non-spore-forming cocci that are coagulase negative and catalase positive. They can be distinguished phenotypically from most staphylococci on the basis of their cellular morphology (they are 2.5 – 4.0 times larger in diameter compared to ''Staphylococcus aureus'') and their positive cytochrome c oxidase reaction. Species in this genus are resistant to bacitracin and lysozyme and sensitive to furazolidone. The DNA base content is 38–45 mol% G+C. The cell walls lack teichoic acid. They are usually unencapsulated.
==Genome== The first genome of this genus was sequenced in 2009<ref name="Baba2009">Baba T, Kuwahara-Arai K, Uchiyama I, Takeuchi F, Ito T, Hiramatsu K. (2009) Complete genome sequence of ''Macrococcus caseolyticus'' strain JCSCS5402, [corrected] reflecting the ancestral genome of the human-pathogenic staphylococci. J. Bacteriol. 191(4):1180-1190</ref>
==Evolution== This genus is the closest known relation of the genus ''Staphylococcus''. Within ''Staphylococcus'', the closest relations of ''Macrococcus'' appear to be the ''Staphylococcus sciuri'' group.
==Clinical== This genus is not known to cause human disease.
A methicillin resistance gene has been identified in this genus.<ref name="Tsubakishita2010">Tsubakishita S, Baba K K-A T, and Hiramatsu K (2010) ''Staphylococcal'' cassette chromosome mec-Like element in ''Macrococcus caseolyticus''. Antimicrob. Agents Chemother. 54 (4) 1469-1475</ref> The significance of this discovery is not yet clear.
==Etymology== {{See also|Bacterial taxonomy}} The name ''Macrococcus'' is a masculine Neo-Latin noun composed of the Greek adjective ''makros (μάκρος)'' meaning "large"<ref>{{LSJ|ma/kros|μάκρος|ref}}</ref> and the Neolatin masculine noun ''coccus'' intended to mean a coccus shaped bacterium, as it comes from the Greek masculine noun ''kokkos (κόκκος)'' meaning "berry",<ref>{{LSJ|ko/kkos|κόκκος|ref}}</ref> consequently the noun ''Macrococcus'', means "large coccus".<ref name="Kloo1998"/>
