The genus Aerococcus was initially described by Williams in his description of Aerococcus viridans ( Williams et al., 1953 ). Aerococcus urinae can, in older males with underlying urinary tract conditions, cause invasive infections such as urosepsis or infective endocarditis. The prognosis of invasive aerococcal infections appears to be relatively favourable despite the old age of patients and their many comorbidities. Aerococcus urinae (AU) is an alpha-hemolytic, coagulase-negative, gram-positive coccus. These features are similar to streptococci and enterococci species and it also resembles staphylococci as it forms in clusters [ 1 ].

Aerococcus urinae Aerococcus urinae is a relatively new species of bacteria in clinical and microbiological practice, first reported in 1989 and designated as a 9 Additional articles not included in the thesis Erik Senneby, Ann-Cathrine Petersson, Magnus Rasmussen. Clinical and microbiological features of bacteraemia with Aerococcus urinae. Clinical Microbiology and Infection, 2012 Jun;18(6):546-50. To the Editor: We report the first case of Aerococcus viridans bacteremia in a patient with HIV infection. Two species in the genus Aerococcus have been implicated as rare pathogens in humans.A. urinae causes urinary tract infections; the other species, A. viridans, a gram-positive coccus considered a contaminant in cultures, has been associated with human infections that included bacteremia Complete Genome Sequences of Aerococcus christensenii CCUG 28831 T, Aerococcus sanguinicola CCUG 43001 T, Aerococcus urinae CCUG 36881 T, The genus Aerococcus encompasses eight species, which are Gram-positive cocci. For a long time, Aerococcus viridans (1953) was the only known species.

The first report on A. urinae was published in 1989 and the name designated in 1992 6 Isolates of A. urinae may easily be mistaken for staphylococci in gram stain, because they appear as gram-positive cocci that are arranged in tetrads or clusters. A. urinae may also cause invasive infections including urosepsis, lymphadenitis, spondylodiscitis and infective endocarditis especially in elderly men with underlying urinary tract diseases. Gram stain. the following information is not yet verified Gram positive cocci, grouped, in pairs, tetrads, clusters or irregular groups. Culture Primary identiﬁcation is based upon Gram stain of alpha-hemolytic colonies which are catalase negative.
ABSTRACT. Aerococcus urinae is a rarely reported pathogen, possibly due to difficulties in the identification of the organism.A. urinae is a gram-positive coccus Aug 13, 2018 The urine culture grew 10-50,000 cfu/ml Aerococcus urinae.
