Cases of endocarditis (n = 7) were high-grade, monomicrobial bacteremia caused by Aerococcus urinae. Patients with endocarditis were younger (66 vs 80 p < 0.05). The risk for endocarditis was higher if duration of symptoms was longer than 7 days (OR 105, 95% CI: 5-2271), or if there were septic emboli (OR 71, 95% CI: 3-1612).

Through searches in the laboratory databases we identify 16 iso- 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 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.
The median age was 74.3 years (12 males and 8 females). 2018-06-15 · Although for many years Aerococcus urinae was considered a urinary contaminant, increasingly it is recognized as an emerging pathogen capable of causing not only urinary tract infection (UTI) but also secondary bacteremia and endocarditis, among others.1 The proportion of patients with aerococcal bacteriuria with symptoms suggestive of UTI ranges from 55-98%.1 So A. urinae… May 28, 2020 Since its first classification, Aerococcus urinae has emerged as a human pathogen capable of causing urinary tract infections (UTI), as well as more invasive infections, including bacteremia, 1,2 endocarditis, 3,4 septicemia 5 and necrotizing soft tissue infections. 6-8 We became particularly interested in A. urinae as a member of the urinary microbiota—the polymicrobial 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. Aerococcus urinae and Aerococcus sanguinicola: Susceptibility Testing of 120 Isolates to Six Antimicrobial Agents Using Disk Diffusion (EUCAST), Etest, and Broth Microdilution Techniques Background: Aerococcus urinae has lately been acknowledged as a cause of infective endocarditis (IE) especially in older males with underlying urinary tract disorders. In this population, cardiac implanted electronical devices (CIED) are not uncommon, but despite the capacity of A. urinae to form biofilm in vitro, no cases of aerococcal CIED infections have been reported to date.
However, there are case reports of AU causing more serious infections, including bacteremia and endocarditis. In our case, AU lead to septicemia, a probable

Apr 23, 2020 A. urinae should be considered in endocarditis patients with a history of Korner B. Bacteremia/septicemia due to Aerococcus-like organisms:
Se hela listan på academic.oup.com 2019-10-23 · Background: Aerococcus urinae is a Gram-positive coccus that is increasingly recognized as a urinary pathogen since the introduction of mass spectrometry for identification of bacteria.
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.

In this population, cardiac implanted electronical devices (CIED) are not uncommon, but despite the capacity of A. urinae to form biofilm in vitro, no cases of aerococcal CIED infections have been reported to date.Case 2010-10-01 urinae (Au) and Aerococcus sanguinicola.2 High-resolution micro-bial identification techniques, such as MALDI-TOF and 16S rDNA gene sequencing, support the notion that is a more Au common cause of urinary tract infection (UTI), endocarditis, bacteremia, and urosepsis than previously thought.2-6 A third Sweden stands up for open access – cancels agreement with Elsevier LUBcat LIBRIS Cases of endocarditis (n = 7) were high-grade, monomicrobial bacteremia caused by Aerococcus urinae.
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
2017-07-01 · Aerococcus urinae is a rare organism isolated from urine cultures. We present a case of an 80 year-old male with bladder cancer and multimorbidity who developed A. urinae infection. A. urinae may cause simple and complicated UTIs, bacteremia, and endocarditis in older adults with multimorbidity, chronic urinary retention, or indwelling catheters.

FICHE TECHNIQUE Aerococcus urinae CLASSIFICATION - NOMENCLATURE Aerococcus urinae appartient au genre Aerococcus qui comprend à l'heure actuelle 8 espèces : 5 espèces isolées chez l'homme: Aerococcus viridans, espèce type, décrit en 1953, A.urinae (1992), A.
Forty-nine cases of Aerococcus bacteremia were deemed as true bloodstream infection. The median age of patients was 79 years (range: 20−97 years). Majority were male (n = 32, 65%) and White (n = 48, 98%).
