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). Aerococci have often been misidentified as streptococci in microbiology laboratories, leading to an underestimation of these bacteria as causes of human infections.

Bacteriological investigation of urine often shows the presence of alpha-haemolytic streptococci, but the clinical significance of this finding may be unclear. Among the alpha-haemolytic streptococci found in urine is Aerococcus urinae, which is pathogenic.

Conduct genome-based taxonomy at. 16S rRNA gene: AJ276512 Analyse FASTA. Valid publication: Lawson PA, Falsen E, Truberg-Jensen K, Collins MD. 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 … 2016-02-02 2020-06-09 A. urinae was in pure culture in 61 %, A. sanguinicola in 46 % and A. viridans in 36 % of the cases. The A. urinae and A. sanguinicola patients were old and many had urinary tract disorders, and a majority had a suspected urinary tract focus of the bacteraemia.

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. 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 Objectives: Aerococcus urinae and Aerococcus sanguinicola cause urinary tract infections (UTIs) and antibiotic treatment recommendations are solely based on in vitro findings and limited clinical experience. Our objective was to investigate the effectiveness of different treatment strategies in aerococcal UTI through a prospective observational Both Aerococcus urinae and Aerococcus sanguinicola have been shown to cause invasive human infections such as sepsis with a urinary tract focus and infective endocarditis (IE),,,, and both these species are also believed to cause urinary tract infections (UTI),. The genus Aerococcus was first proposed in 1953 to describe a Gram-positive, microaerophilic, catalase-negative bacteria that were morphologically different from Streptococcus species, and now includes eight distinct species – Aerococcus viridans, A. urinae, A. sanguinicola, A. christensenii, A. urinaehominis, A. urinaeequi, A. suis, and A. vaginalis (Senneby, 2018, Williams et al., 1953).
