DISCLOSURES: No Apr 23, 2020 A. urinae should be considered in endocarditis patients with a history of Korner B. Bacteremia/septicemia due to Aerococcus-like organisms: This is a case of septic spondylodiscitis and bacteremia due to Aerococcus urinae with a urinary starting point. Corresponding author: Amina Lyagoubi. Faculty of However, there are case reports of AU causing more serious infections, including bacteremia and endocarditis. In our case, AU lead to septicemia, a probable Aerococci occur naturally in dust, air, vegetation, and hospital environments.

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 ]. 2020-06-09 prosthetic aortic valve caused by Aerococcus urinae. A. urinae affects elderly patients with comorbidities and urinary tract pathologies. Infective endocarditis should be suspected in all patients with Aerococcus bacteremia and urinary source is usually the source of bacteremia. Optimal treatment of A. urinae infective endocarditis is 2018-02-16 Results: A total of 20 Aerococcus spp.

Blood cultures revealed gram positive cocci in clusters (2/4 bottles), which ultimately speciated after additional testing as Aerococcus urinae. Aerococcus urinae is a rare organism infrequently isolated from cultures.

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 ). 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.

Aerococcus urinae is a pathogen that rarely causes severe or fatal infections. We describe four cases of severe A. urinae bloodstream infections.

Embolization is frequently reported with Aerococcus urinae endocarditis (AUE); hence, the presentation is highly variable. Aerococcus urinae, which has been more extensively studied, also infects elderly men with urinary tract abnormalities, but patients with A urinae bacteremia seem to have less neurological disease [7]. positive for A. urinae and Escherichia coli.

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). Although the 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 … 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 ].
