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 ). Naghibi M, Javaid MM, Holt SG. Case study: Aerococcus urinae as pathogen in peritoneal dialysis peritonitis--a first report. Perit Dial Int. 2007;27(6):715-6. Colakoglu S, Turunc T, Taskoparan M, et al. Three cases of serious infection caused by Aerococcus urinae: A patient with spontaneous bacterial peritonitis and two patients with bacteremia. Two species in the genus Aerococcus have been implicated as rare pathogens in humans. 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 ).

Aerococcus urinae bacteremia

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). 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]. A. urinae shares features with staphylo-cocci, streptococci and enterococci as the bacterium grows Aerococcus urinae is a Gram-positive, catalase-negative coccus that was first described in the 1990s as a causative organism of urinary tract infections . A. urinae levels of 0.3 to 0.8% in urine specimens are reported, with a preponderance in patients with underlying urologic conditions ( 6 , 8 ).

Aerococcus urinae muodostaa verimaljalle viljeltynä 24 tunnin inkubaatioajalla hiilidiok- sidiolosuhteissa pieniä noin 0,5 mm kokoisia pesäkkeitä, jotka ovat ulkonäöltään kupe- ria, läpikuultavia ja kiiltäviä (Christensen – Ruoff 2015: 428).

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.

2019-10-23 2020-04-23 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.

It is now being recognized as an emerging cause of UTIs, especially in elderly males with urologic conditions, with the potential to cause bacteremia if not appropriately treated.

Aerococcus urinae is a Gram‐positive bacterium that can cause invasive infection, including infectious endocarditis (IE), mainly in older men. A. urinae is often misclassified in routine diagnostic laboratories.

Jongdem1@kg.nl 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. 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. Aerococcus urinae is a Gram‐positive bacterium that can cause invasive infection, including infectious endocarditis (IE), mainly in older men.

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 ]. 2020-06-09 prosthetic aortic valve caused by Aerococcus urinae.

None of the patients had cardiac devices or were active intravenous drug users. 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 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.
