Aerococcus urinae is a member of the bacterial genus Aerococcus.The bacterium is a Gram-positive, catalase-negative coccus growing in clusters. Isolates of this genus were originally isolated in 1953 from samples collected in the air and dust of occupied rooms and were distinguished by their tetrad cellular arrangements. [2]
Aerococcus is a genus in the phylum Bacillota . [1] The genus was first identified in 1953 from samples of air and dust as a catalase -negative, gram -positive coccus that grew in small clusters. [ 2 ]
Aerococcus viridans is a member of the bacterial genus Aerococcus. It is a causative agent of gaffkaemia, a disease of lobsters, [1] ...
The viridans streptococci are a large group of commensal streptococcal Gram-positive bacteria species that are α-hemolytic, producing a green coloration on blood agar plates (hence the name "viridans", from Latin "vĭrĭdis", green), although some species in this group are actually γ-hemolytic, meaning they produce no change on blood agar.

However, it has retained some clinical usefulness even after the taxonomic changes, [1] and as of 2018, Lancefield designations are still often used to communicate medical microbiological test results. The classification assigns a letter code to each serotype. There are 20 described serotypes assigned the letters A to V (excluding E, I and J). [3]

Aerococcus sanguinicola is a member of the bacterial genus Aerococcus and is a Gram-positive, catalase-negative coccus growing in clusters.This species was defined in 2001 [1] and has since then been increasingly recognized as a pathogen causing urinary tract infections [2] [3] and also invasive infections including infective endocarditis.
