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 is a rare organism infrequently isolated from cultures. Mostly known to cause urinary tract infection, it can cause bacteremia leading to severe urosepsis and infective endocarditis. 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].

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). Two species in the genus Aerococcus have been implicated as rare pathogens in humans.

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 2021-01-01 2010-09-01 Clin Microbiol Infect ABSTRACT: 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.

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 ).

Clinical significance Isolates of this species were originally isolated from the urine of patients with urinary tract infections and were denoted Aerococcus-like organisms. Infections with this bacterium has likely been underestimated. 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 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).

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. We report a case of abdominal aortitis (with aneurysm) caused by A urinae in a male with recurrent urinary tract infections and recently treated A urinae bacteremia.

Conclusions: Aerococcus urinae is a rare microorganism usually found in the urinary tract, which until recently was thought to be a urinary contaminant lacking clinical significance. 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.
