Aerococcus urinae is a Gram-positive organism, initially identified in 1992. It is known to cause urinary tract infections (UTIs), bacteremia, and endocarditis in humans. There is limited data regarding the susceptibility of A. urinae to first-line antimicrobials indicated for the treatment of UTIs.

isolates were identified over the study period of 9 years. Of these, Aerococcus urinae was isolated in 10 (50%), Aerococcus viridans in 6 (30%), and Aerococcus spp. (not speciated) in 4 (20%). The median age was 74.3 years (12 males and 8 females). The two most frequent presentations were fever (15 of 20) and altered mentation (6 of 15). Aerococcus urinae is a rare organism infrequently isolated from cultures.

Aerococcus urinae bacteremia

A. urinae is a gram-positive coccus occurring in tetrads or pairs, similar to the α-hemolytic Streptococci, which is commonly found in the urinary tract in children and elderly people. Aerococcus urinae may cause urinary tract infections, bacteremia, and endocarditis. No standardized susceptibility test methods or interpretive criteria have been proposed for this organism. This study reports the MIC results for 128 A. urinae isolates tested by broth microdilution. The isolates had … Aerococcus urinae is a rare organism infrequently isolated from cultures. Mostly known to cause urinary tract infection, it can cause bacteremia leading to severe urosepsis and infective endocarditis. Embolization is frequently reported with Aerococcus urinae endocarditis (AUE); hence, the presentation is highly variable.

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.

Aerococcus urinae (A.urinae) isanewcomer to clinical and microbiological practice. This bacterium is mainly associated with urinary tract infections (UTI) especially in elderly patients with predisposing conditions. A. urinae naturally is isolated from dust, air, vegetation, and hospital environments. 2015-09-28 · Aerococcus urinae (A.urinae) is a rare bacterium that can occur in a urinary tract infection, infective endocarditis, blood stream, and spinal disc infections.

A. urinae naturally is isolated from dust, air, vegetation, and hospital environments.

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 (1, 3), septic arthritis (3), and infectious endocarditis (4, 5).
