This species was defined in 2001 and has since then been increasingly recognized as a pathogen causing urinary tract infections and also invasive infections including infective endocarditis. Aerococcus urinae and Aerococcus sanguinicola are newcomers to clinical and microbiological practice. The first report on A. urinae was published in 1989 (14) and the name designated in 1992 (1) and A.sanguinicola was named in 2001 (40). Aerococcus urinae is a pathogen that rarely causes severe or fatal infections.

Aerococcus sanguinicola pyr

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. Eighty percent of the A. urinae patients were men.

Urine cultures, however, were negative. 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.

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.

The majority of urinary isolates are Aerococcus urinae (55–66%) followed by Aerococcus sanguinicola (26–46%). Aerococcus viridans is uncommon . Aerococci are also presumed to be part of normal genitourinary tract flora, and isolation in urine may Aerococcus The Aerococcus sp. are sensitive to vancomycin, do not form gas from glucose, and are generally PYR positive but are LAP negative.

Most Aerococcus species will grow in Salt Broth but A. sanguinicola is the only species that is usually Bile Esculin (+). 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 Aerococcus urinae and Aerococcus sanguinicola, two frequently misidentified uropathogens Scand J Infect Dis . 2010 Oct;42(10):775-80.
