Aerococcus urinae is a Gram-positive alpha-hemolytic bacterium first isolated and identified from urine from patients with UTI ( 8 ). Since its discovery, A. urinae has been isolated from a wide variety of patients, both male and female, ranging from children to the elderly ( 9 ).

Aerococcus urinae may cause urinary tract infections, bacteremia, and endocarditis. No standardized susceptibility test methods or interpretive criteria have been proposed for this organism.

Se hela listan på antimicrobe.org Aerococcus urinae is a pathogen that rarely causes severe or fatal infections. We describe four cases of severe A. urinae bloodstream infections. All patients had underlying urologic conditions. Urine cultures, however, were negative.

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).

This study reports the MIC results for 128 A. urinae isolates tested by broth microdilution.

Jacopo Guccione.

Results: A total of 20 Aerococcus spp. 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).

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%). The most common species was Aerococcus urinae (n = 38, 78%).

Aerococcus urinae is a Gram-positive coccus that was identi-ﬁed as a possible pathogen colonizing the human urinary tract and was originally designated as an Aerococcus-like organism [1,2]. The bacterium was recognized as a distinct species in 1992 [3].

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.

This study reports the MIC results for 128 A. urinae isolates tested by broth microdilution. The isolates had low MICs to amoxicillin, cefotaxime, ceftriaxone, doxycycline, linezolid, meropenem Aerococcus urinae may cause urinary tract infections, bacteremia, and endocarditis. No standardized susceptibility test methods or interpretive criteria have been proposed for this organism. To evaluate procedures for the identification of Aerococcus urinae, we examined 24 α‐hemolytic non‐enterococcal bacterial isolates from 4373 urine samples.Published procedures were compared with 16s rRNA sequencing and biochemical profiling (BBL‐Crystal‐GP). 16s rRNA sequencing and BBL‐Crystal‐GP identified the same 13 isolates as A. urinae. Parent taxon: Aerococcus Williams et al.

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. 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… Aerococcus urinae and Aerococcus sanguinicola: Susceptibility Testing of 120 Isolates to Six Antimicrobial Agents Using Disk Diffusion (EUCAST), Etest, and Broth Microdilution Techniques Aerococccus urinae (AU) is a pathogen mainly identified in male urinary tract infections and responsible for bacteremia and endocarditis. To the best of our knowledge, there are only five patients with osteomyelitis due to AU described in the literature. All of them had urinary tract disease or systemic conditions such as diabetes, and two were associated with an endocarditis.
