Aerococcus urinae has lately been acknowledged as a cause of infective endocarditis (IE) especially in older males with underlying urinary tract disorders. In this 

The Gram-positive bacterium Aerococcus urinae can cause infectious endocarditis (IE) in older persons. Biofilm formation and platelet aggregation is believed to contribute to bacterial virulence in IE. Five A. urinae isolates from human blood were shown to form biofilms in vitro and biofilm formation was enhanced by the presence of human plasma. Aerococcus urinae is a Gram-positive coccus with the capacity to cause urinary tract infections (), infectious endocarditis (IE) (), and spondylodiscitis (). A. urinae was recognized as a distinct species in 1992 and can be misreported as an alpha-hemolytic streptococcus due to its growth characteristics and hemolysis pattern.

The risk for endocarditis was higher if duration of symptoms was longer than 7 days (OR 105, 95% CI: 5-2271), or if there were septic emboli (OR 71, 95% CI: 3-1612). Aerococcus urinae (A.urinae) is a rare bacterium that can occur in a urinary tract infection, infective endocarditis, blood stream, and spinal disc infections. A. urinae is a gram-positive coccus occurring in tetrads or pairs, similar to the α-hemolytic Streptococci, which is commonly found in the urinary tract in children and elderly people. Background. Aerococcus urinae is a gram-positive, alpha-hemolytic coccus bacterium primarily implicated in less than 1 % of all symptomatic urinary tract infections.

Initial laboratory work returned with blood and urine cultures positive for Aerococcus urinae. A transthoracic echocardiogram further revealed new aortic regurgitation. Given this, a transesophageal echocardiogram was completed, confirming new aortic insufficiency as well as findings of infective endocarditis.

Patients with endocarditis were younger (66 vs 80 p < 0.05). The risk for endocarditis was higher if duration of symptoms was longer than 7 days (OR 105, 95% CI: 5−2271), or if there were septic emboli (OR 71, 95% CI: 3–1612). Aerococcus urinae is a rare cause of urinary tract infections, mainly in elderly men with underlying urinary tract pathologies. In addition, it has been described as a pathogen in balanitis, soft tissue infections, septicemia and endocarditis.

Background: Aerococcus urinae is a gram-positive, alpha-hemolytic coccus bacterium primarily implicated in less than 1 % of all symptomatic urinary tract infections. Risk factors for disease include male gender, advanced age, and comorbid genitourinary tract pathology.

Heart valve specimens from two patients were obtained during surgery at Charité–Universitätsmedizin and 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. 2020-01-01 · Infective endocarditis (IE) caused by Aerococcus urinae is rare. The true incidence rate of this pathogen is likely underestimated as this is easily misidentified as Staphylococci or Streptococci.

Less than 50 cases of A. urinae associated with  Feb 28, 2020 Abstract. Aerococcus urinae is a gram positive, alpha haemolytic cocci that rarely is associated with urinary tract infections, bacteraemia and  It is a rare cause of infections in humans, but cases of urinary tract infection (UTI), bacteraemia, endocarditis and  Background. Aerococcus urinae is a rare causative pathogen of infective endocarditis that results in a high risk of embolic events. The mortality rate for A urinae  Background. Aerococcus urinae has lately been acknowledged as a cause of infective endocarditis (IE) especially in older males with underlying urinary tract  urinae may also cause invasive infections including urosepsis and infective endocarditis, especially in elderly men with underlying urinary tract diseases.

2018-01-01 · Aerococcus urinae is a Gram-positive bacterium which can cause urinary tract infections (UTIs), bacteremia, and infective endocarditis (IE) [1-3]. After the introduction of MALDI-TOF MS for species determination in medical microbiology, A. urinae has been increasingly identified as a relatively common cause of both UTIs and bacteremia [4, 5].

Less than fifty cases of A. urinae infective endocarditis (IE) have been described in the literature.
