Aerococcus species: A. viridans, A. urinae och A. sanguinicola växer med alfa-hemolys på blodagar och framträder i gramfärgade preparat som en grampositiv kock i par, tetrad eller kluster. Genus Leuconostoc är katalasnegativa bakterier som i gramfärgat preparat framträder som ovoida kocker. 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 first report on A. urinae was published in 1989 (14) and the name designated in 1992 and A.sanguinicola was named in 2001 . Secondly, Aerococcus urinae also tends to be resistant to the antibiotics Trimethoprim and Ciprofloxacin, both commonly used to treat UTIs. Patients often only start to feel better if given active antibiotics such as Amoxicillin or Nitrofurantoin. Thirdly, Aerococcus urinae tends only to cause UTIs in the Aerococcus urinae is a Gram-positive alpha-hemolytic bacterium first isolated and identified from urine from patients with UTI (8).

Aerococcus urinae is often misclassified in routine diagnostic laboratories. A. urinae shares features with staphylococci, streptococci and enterococci as the bacterium grows in clusters, displays a-haemolysis when grown on blood agar, and is resistant to sulphonamide. We report here, a case study of A. urinae, which initially was misdiagnosed. Aerococcus urinae is a Gram-positive bacterium associated with urinary tract infections.. Classification. Aerococcus urinae is a member of the bacterial genus Aerococcus.The bacterium is a Gram-positive, catalase-negative coccus growing in clusters.

Infektion Flashcards Quizlet

A. urinae may cause simple and complicated UTIs, bacteremia, and endocarditis in older adults with multimorbidity, chronic urinary retention, or indwelling catheters. Aerococcus urinae can, in older males with underlying urinary tract conditions, cause invasive infections such as urosepsis or infective endocarditis. The prognosis of invasive aerococcal infections appears to be relatively favourable despite the old age of patients and their many comorbidities. Aerococcus urinae is a rarely reported pathogen, possibly due to difficulties in the identification of the organism.

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) [3,6–9] and both these species are also believed to cause urinary tract infections (UTI) [10,11]. Both species can form biofilms on foreign ma- Among the alpha-haemolytic streptococci found in urine is Aerococcus urinae, Nitrofurantoin (Furadantin) has recently become established as a useful drug in urinary tract infections.
