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.

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. [4]
Viridans may refer to: Viridans streptococci, large group of bacteria species; Achatinella viridans, species of mollusc; Aerococcus viridans, species of bacteria; Apotoforma viridans, species of moth; Blennidus viridans, species of ground beetle; Ericydeus viridans, species of true weevil; Eucalyptus socialis subsp. viridans, species of plant
Gaffkaemia was first discovered in 1947 in American lobsters (Homarus americanus) in a holding tank in Maine. [1] It was originally described as "Gaffkya homari" by Hitcher and Snieszko, but the genus name Gaffkya was rejected in 1971, [2] [3] and the gaffkaemia bacterium was recognised as a subspecies or variety of Aerococcus viridans by Kelly and Evans in 1974.
Bacteriuria is assumed if a single bacterial species is isolated in a concentration greater than 100,000 colony forming units per millilitre of urine in clean-catch midstream urine specimens. [16] In urine samples obtained from women, there is a risk for bacterial contamination from the vaginal flora.
