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.

Several other species in the Aerococcus genus have been identified, including the pathogenic A. sanguinicola and the less-pathogenic A. christensenii and A. urinaehominus [ 3 - 5 ]. While rarely recognized in the past, A. urinae has become more commonly isolated in bacterial cultures, as bacterial detection has improved [ 6 ]. 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 . However, A sanguinicola has often reduced susceptibility to fluoroquinolones [1, 3, 5].

Treatment options are therefore important. Archive.9 Additional closed Aerococcus genomes were published by Carkaci et al10 in 2016; this included A. sanguinicola CCUG 43001T, Au CCUG 36881T, and A. viridans CCUG 4311T. Recently, Au and A. sanguinicola genomes were characterized, postulating a core genome and determining the extent of genomic diversity among various clinical isolates.11 Aerococcus urinae and Aerococcus sanguinicola can both cause urinary tract infections (Cattoir et al. 2010. Aerococcus urinae and Aerococcus sanguinicola, two frequently misidentified uropathogens, Scand J Infect Dis 42: 775‐780). (2010).

Species belonging to the Aerococcus genus are isolated from the urine and blood of elderly patients suffering from urinary tract infections (UTIs). However, the clinical significance, phenotypic features and antimicrobial susceptibilities of these underestimated and/or misidentified species remain u …

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. 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.

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. 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.

FIG. 1. Upper part of the ﬁgure shows a blood isolate of Aerococcus urinae grown for 24 h on blood agar in 5% CO 2. The small colonies with clear α-haemolysis can be seen. Lower part of the panel shows a blood isolate of Aerococcus sanguinicola grown on the same plate. The colonies are larger, whiter and the haemolysis is not as pronounced. 2011-08-01 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.

EUCAST breakpoints are used to categorise results into three susceptibility categories: 25, Aerococcus sanguinicola and urinae, New comments

are problematic for clinical lab-oratories and clinicians. There are a limited number of published studies that address susceptibility testing of A. urinae, and these usually include a small number of isolates. A variety of test meth-ods have been reported, and interpretive criteria for streptococci as Aerococcus sanguinicola by 16S rDNA sequencing and thus disregarded.

Aerococci have often been misidentified as streptococci in microbiology laboratories, leading to an underestimation of these bacteria as causes of human infections. An increased awareness of aerococci and the introduction of matrix-assisted laser desorption ionization time-of-flight mass spectrometry, has led to an increased isolation of Aerococcus urinae and Aerococcus sanguinicola from human
