Aerococcus

Aerococcus is a genus in the phylum <a href="/facts/Bacillota/FxP0p0n8">Bacillota</a> (<a href="/facts/Bacteria/wC8xSCsU">Bacteria</a>). The genus was first identified in 1953 from samples of air and dust as a <a href="/facts/Catalase-peroxidase/Uon0meGI">catalase</a>-negative, <a href="/facts/Gram_stain/E20u5av2">gram</a>-positive <a href="/facts/Coccus/51QVlEDC">coccus</a> that grew in small clusters. They were subsequently found in hospital environments and meat-curing brines. It has been difficult to identify as it resembles <a href="/facts/Streptococcus/Fx8lJ0nz">alpha-hemolytic Streptococcus</a> on <a href="/facts/Agar_plate/eMdxP8rB">blood agar plates</a> and is difficult to identify by biochemical means. Sequencing of <a href="/facts/16S_ribosomal_RNA/XCgSahoy">16S rRNA</a> has become the gold standard for identification, but other techniques such as <a href="/facts/Matrix-assisted_laser_desorption%2fionization/nBBXfb2Q">MALDI-TOF</a> have also been useful for identifying both the genus and species.
