MALDI-TOF MS has led to an increased identification of aerococcal bacteremia. A. urinae remains the most common Aerococcus in blood cultures and in
Feb 19, 2018 Other presentations have included abscess formation, bacteremia, osteomyelitis, ocular infections, and granulomatous disease that mimics
All of them had urinary tract disease or systemic conditions such as diabetes, and two were associated with an endocarditis. We described the Aerococcus urinae is a Gram-positive bacterium which can cause urinary tract infections (UTIs), bacteremia, and infective endocarditis (IE) [1–3]. After the introduction of MALDI-TOF MS for species determination in medical microbiology, A. urinae has been increasingly identified as a relatively common cause of both UTIs and bacteremia [ 4 , 5 ]. Of these, Aerococcus urinae was isolated in 10 (50%), Aerococcus viridans in 6 (30%), and Aerococcus species (not speciated) in 4 (20%) patients. Seven of 20 (35%) had blood cultures with polymicrobial growth, 3 with coagulase-negative staphylococci, 2 with Enterococcus faecalis and the other 3 with Acinetobacter baumannii, Diphtheroids, and Proteus mirabilis [ Table 1 ]. 2020-04-23 · Melnick S, Nazir S, Hingorani R, Wexler P. Aerococcus urinae, a rare cause of infective endocarditis. BMJ Case Reports.
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 ]. 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.

Aerococcus urinae may cause urinary tract infections, bacteremia, and endocarditis. 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.
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. A. urinae has been known to cause urinary tract infections, bacteremia/septicemia Clinical and microbiological features of bacteraemia with Aerococcus urinae.
All patients had a genitourinary source of infection, and five had at least one underlying urological abnormality like nephrolithiasis, prostate cancer, BPH, phimosis, and bladder cancer. None of the patients had cardiac devices or were active intravenous drug users.
