Aerococci occur naturally in dust, air, vegetation, and hospital environments. A. urinae has been known to cause urinary tract infections, bacteremia/septicemia

Aerococcus urinae is an uncommon urinary tract pathogen that causes infections predominantly in elderly persons with local or general predisposing conditions. During a one-year study, the clinical features ofAerococcus urinae urinary tract infections (≥105 cfu/ml) were investigated in two large medical microbiology laboratories in the Netherlands.

A. urinae - associated with urinary tract infections and rarely with endocarditis, septicemia and peritonitis. A. urinaehominis - implicated in urinary tract infections. Usual Susceptibility Pattern 2015-09-28 1997-12-01 Aerococcus urinae is a Gram-positive bacterium which can cause urinary tract infections (UTIs), bacteremia, and infective endocarditis (IE) [1–3]. After the introduction of MALDI-TOF MS for species determination in medical microbiology, A. urinae has been increasingly identified as a relatively common cause of both UTIs and bacteremia [ 4 , 5 ]. 2019-10-23 2020-04-23 Aerococcus urinae (A.urinae) isanewcomer to clinical and microbiological practice.

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 … Aerococcus urinae is found in the urinary tract and most, but not all, studies implicate A. urinae as a pathogen in urinary tract infections [ 1,2,4,7,8 ]. Importantly, A. urinae has been described as a cause of invasive infections such as infectious endocarditis (IE) [ 9 ], spondylodiscitis [ 10 ], septicaemia [ 11 ], cellulitis [ 7 ] and peritonitis [ 12 ]. Aerococci urinae is a Gram-positive, catalase-negative, bacterium that grows in clusters, often appearing in colonies that resemble Streptococci viridans [ 1 ]. Its genus was first described in 1953, with the first reported case of A. urinae in a human described in 1992 [ 1, 2 ].

A. urinae naturally is isolated from dust, air, vegetation, and hospital environments. Aerococci have often been misidentified as streptococci in microbiology laboratories, leading to an underestimation of these bacteria as causes of human infections. An increased awareness of aerococci and the introduction of matrix-assisted laser desorption ionization time-of-flight mass spectrometry, has led to an increased isolation of Aerococcus urinae and Aerococcus sanguinicola from human 2018-06-15 Background: Aerococcus urinae and Aerococcus sanguinicola are relatively newcomers and emerging organisms in clinical and microbiological practice.

Aerococcus urinae is a Gram-positive, catalase-negative coc-cus that was ﬁrst described in the 1990s as a causative organism of urinary tract infections (1). A. urinae levels of 0.3 to 0.8% in urine specimens are reported, with a preponderance in pa-tients with underlying urologic conditions (6, 8).

In the last one to two decades additionally six species have been included in the genus: A. urinae (1992), Aerococcus christensenii (1999), Aerococcus urinae hominis (2001), A. sanguinicola (2001), Aerococcus urinaeequi (reclassification of Pediococcus urinae equi, 2005), Aerococcus suis (2007), and Aerococcus vaginalis (2014).

Aerococcus urinae accounts for between 0.2% and 0.8% of positive urinary cultures, but up to 45% of positive cultures come from asymptomatic patients . Bacteremia is the most common invasive disease caused by A urinae; however, isolates from a variety of other clinical sites has been reported .
