Aerococcus urinae is a rarely reported pathogen, possibly due to difficulties in the identification of the organism. A. urinae is a gram-positive coccus that grows in pairs and clusters, produces alpha-hemolysis on blood agar, and is negative for catalase and pyrrolidonyl aminopeptidase. Some of these characteristics and its being absent from the databases of most commercial identification

Aerococcus species är närbesläktade med enterokocker. De finns i miljön, men kan också isoleras från human hudflora. A. urinae och A.sanguinicola förekommer vid urinvägsinfektion, septikemi, endokardit och meningit. A. viridans förekommer vid urinvägsinfektioner om predisponerande faktorer finns. Har isolerats vid endokardit.

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.

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.

Aerococcus viridans is uncommon . Aerococci are also presumed to be part of normal genitourinary tract flora, and isolation in urine may 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.

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

Table  25 Apr 2015 Ideal practice is based on culture and sensitivity. Empiric Tx may be too BROAD Aerococcus urinae – gram+.

Aerococcus: an increasingly acknowledged human pathogen. Rasmussen, Magnus LU () In Clinical Microbiology and Infection 22 (1). p.22-27. Mark; Abstract Aerococci have often been misidentified as streptococci in microbiology laboratories, leading to an underestimation of these bacteria as causes of human infections.

The colonies are larger, whiter and the haemolysis is not as pronounced. 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. Vi fann att MALDI-TOF MS var en metod med god sensitivitet och specificitet i avseende att identifiera A. urinae och A. sanguinicola jämfört med en referensmetod (sekvensering av 16S rRNA-genen).

A. urinae and A. sanguinicola were isolated in approximately 1 % of all urine samples in Skåne. The patients were of old age and gender was almost equally distributed between men and women. 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.
