positive for A. urinae and Escherichia coli. Aerococcus urinae is a Gram-positive, catalase-negative coc-cus that was ﬁrst described in the 1990s as a causative organism of urinary tract infections (1). A. urinae levels of 0.3 to 0.8% in urine specimens are reported, with a preponderance in pa-tients with underlying urologic conditions (6, 8). Although the Aerococcus urinae is a member of the bacterial genus Aerococcus.

Forty-nine cases of Aerococcus bacteremia were deemed as true bloodstream infection. The median age of patients was 79 years (range: 20−97 years). Majority were male (n = 32, 65%) and White (n = 48, 98%). The most common species was Aerococcus urinae (n = 38, 78%). Aerococcus urinae is a Gram-positive bacterium that can cause invasive infection, including infectious endocarditis (IE), mainly in older men. A. urinae is often misclassiﬁed in routine diagnostic laboratories.

Results: A total of 20 Aerococcus spp. isolates were identified over the study period of 9 years. Of these, Aerococcus urinae was isolated in 10 (50%), Aerococcus viridans in 6 (30%), and Aerococcus spp. (not speciated) in 4 (20%). The median age was 74.3 years (12 males and 8 females). The two most frequent presentations were fever (15 of 20) and altered mentation (6 of 15).

All of them had urinary tract disease or systemic conditions such as diabetes, and two were associated with an endocarditis.

Aerococcus urinae is a Gram-positive coccus that was identi-ﬁed as a possible pathogen colonizing the human urinary tract and was originally designated as an Aerococcus-like organism [1,2]. The bacterium was recognized as a distinct species in 1992 [3]. A. urinae shares features with staphylo-cocci, streptococci and enterococci as the bacterium grows Aerococcus urinae is a Gram-positive, catalase-negative coccus that was first described in the 1990s as a causative organism of urinary tract infections .

Aerococcus urinae is a Gram-positive alpha-hemolytic bacterium first isolated and identified from urine from patients with UTI ( 8 ). Since its discovery, A. urinae has been isolated from a wide variety of patients, both male and female, ranging from children to the elderly ( 9 ).

A. urinae may cause simple and complicated UTIs, bacteremia, and endocarditis in older adults with multimorbidity, chronic urinary retention, or indwelling catheters. Aerococcus urinae is a Gram-positive bacterium that can cause invasive infection, including infectious endocarditis (IE), mainly in older men. A. urinae is often misclassiﬁed in routine diagnostic laboratories. Through searches in the laboratory databases we identify 16 iso- Aerococcus urinae (A.urinae) is a rare bacterium that can occur in a urinary tract infection, infective endocarditis, blood stream, and spinal disc infections.
