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] They were subsequently found in hospital environments and meat-curing brines. [3]
Aerococcus viridans is a member of the bacterial genus Aerococcus. It is a causative agent of gaffkaemia , a disease of lobsters , [ 1 ] and is used as a commercial source for lactate oxidase. [ 2 ]

An improper technique can produce false results, for example, leukocytes and erythrocytes precipitate at the bottom of the container and may not be detected if the sample is not properly mixed, and in the same way, if an excess of urine remains on the strip after it has been removed from the test sample, may cause the reagents to leak from the ...
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.
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
The instrument scans the MGIT every 60 minutes for increased fluorescence. Analysis of the fluorescence is used to determine if the tube is instrument positive; i.e., the test sample contains viable organisms. An instrument-positive tube contains approximately 10 5 to 10 6 colony-forming units per milliliter (CFU/mL).
