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 In 2001 the clinically relevant species Aerococcus sanguicola [22], which was later renamed A. sanguinicola, was defined. Two additional aerococcal species have been identified in humans: Aerococcus christensenii [23] from the vaginal tract, which seems to be an uncommon cause of infections [24], and Aerococcus TEXT.
Commercial ID systems have limited abilities to ID A. urinae/A. viridans and will not recognize A. sanguinicola. The most distinguishing characteristic of Aerococcus sp. is their gram stain morphology of large GPCs in This report describes the clinical sources and phenotypic characterization of 16 isolates of Aerococcus sanguinicola.Sixteen conventional tests were used to describe and differentiate the 16 isolates of A. sanguinicola from 30 strains of Aerococcus viridans, 27 strains of Aerococcus urinae, and a single strain each of Aerococcus christensenii and Aerococcus urinaehominis. Aerococcus sanguinicola is sensitive to most antibiotics likely to be used for empirical treatment of septicaemia such as β-lactams and vancomycin [ 5 ]. However, A sanguinicola has often reduced susceptibility to fluoroquinolones [ 1, 3, 5 ].
Both species have worldwide been associated with urinary tract infections. More rarely cases of bacteremia/septicemia and infective endocarditis have been reported.

However, the clinical significance, phenotypic features and antimicrobial susceptibilities of these underestimated and/or misidentified species remain unclear. Aerococcus urinae and Aerococcus sanguinicola: Susceptibility Testing of 120 Isolates to Six Antimicrobial Agents Using Disk Diffusion (EUCAST), Etest, and Broth Microdilution Techniques Derya Carkaci, Xiaohui Chen Nielsen, Kurt Fuursted, Robert Skov, Ole Skovgaard , Emilio Perez Trallero, Reto Lienhard, Jenny Åhman, Erika Matuschek, Gunnar Kahlmeter, Jens Jørgen Christensen We identified 64 Aerococcus urinae isolates and 40 Aerococcus sanguinicola isolates, which correlates with an incidence of 33 cases of aerococcal bacteriuria per 100,000 inhabitants per year. The median age was 83years for all patients with aerococcal bacteriuria, which was significantly higher than for patients with Escherichia coli or Enterococcus faecalis bacteriuria.

Epidemiology and antibiotic susceptibility of aerococci in
Clinical studies are needed to establish clinical breakpoints and optimal treatment. Aerococcus urinae and Aerococcus sanguinicola are relatively newcomers and emerging organisms in clinical and microbiological practice. Both species have worldwide been associated with urinary tract infections. More rarely cases of bacteremia/septicemia and infective endocarditis have been reported. Treatment options are therefore important. A. sanguinicola are catalase-negative, vancomycin-susceptible, gram-positive cocci arranged in clusters and tetrads, as are all Aerococcus species except A. christensenii (which is arranged in short chains). A retrospective chart review was performed on 92 patients from whom 118 isolates of Aerococcus sanguinicola (n = 52) or Aerococcus urinae (n = 66) were obtained from urine cultures between October 2007 and June 2008 to assess clinical presentation and antimicrobial susceptibilities.

The objective of this study was to evaluate three methods for susceptibility testing of A. urinae and A. sanguinicola using EUCAST media. Aerococcus sanguinicola is a cause of urinary tract infections, blood stream infections, and infective endocarditis (IE). 2017-08-01 ABSTRACT 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. The isolates had low MICs to amoxicillin, cefotaxime, ceftriaxone, doxycycline, linezolid, meropenem Aerococcus Urinae and Aerococcus Sanguinicola: Susceptibility The Open Microbiology Journal, 2017, Volume 11 161. Conclusion: All isolates were found susceptible to all six antimicrobial agents: penicillin, cefotaxime, meropenem, vancomycin, linezolid, and sanguinicola n=13, A. viridans n=14 and A. christensenii n=1).

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. 2021-01-01 · All Aerococcus species were susceptible to vancomycin . A. urinae, A. sanguinicola, and Aerococcus sp. were all susceptible to both penicillin and ceftriaxone. The majority of Aerococcus viridans and Aerococcus viridans/urinaeequi isolates were not susceptible to penicillin and Aerococcus urinae and Aerococcus sanguinicola are relatively newcomers and emerging organisms in clinical and microbiological practice.
The aerococcal isolates displayed low MICs for ampicillin, cefalotin, mecillinam, and nitrofurantoin.
