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).

The most distinguishing characteristic of Aerococcus sp. is their gram stain morphology of large GPCs in Aerococci have often been misidentified as streptococci in microbiology laboratories, leading to an underestimation of these bacteria as causes of human infections. An increased awareness of aerococci and the introduction of matrix-assisted laser desorption ionization time-of-flight mass spectrometry, has led to an increased isolation of Aerococcus urinae and Aerococcus sanguinicola from human Aerococcus sanguinicola and urinae * 16. 16 Nitrofurantoin exhibits in vitro activity against these bacteria; however, the safety and effectiveness of nitrofurantoin in treating clinical infections due to these bacteria have not been established in adequate and well controlled clinical trials.

In complicated UTI, ampicillin is probably a safe treatment option, whereas nitrofurantoin is likely effective in uncomplicated UTI. Comparative 16S rRNA gene sequencing demonstrated that the organism represents a new subline within the genus Aerococcus. The unknown bacterium was readily distinguished from the three currently recognized Aerococcus species, Aerococcus christensenii, Aerococcus urinae and Aerococcus viridans, by biochemical tests and electrophoretic analysis of whole-cell proteins.

Aerococcus urinae and Aerococcus sanguinicola: Susceptibility Testing of 120 Isolates to Six Antimicrobial Agents Using Disk Diffusion (EUCAST), Etest, and Broth Microdilution Techniques Bakterien har fått navnet Aerococcus urinae og er en alfahemolytisk (grønn) streptokokk. Bakterien er også beskrevet som årsak til septikemi og endokarditt (4, 5). Det er flere arter i samme gruppe med klinisk relevans. Stomatococcus, Gemella og Aerococcus viridans forårsaker endokarditt, bakteriemi, meningitt og peritonitt.

Aerococcus urinae and A. sanguinicola can cause urinary tract infections and invasive infections, such as urosepsis and infective endocarditis. Due to difficulties in biochemical identification of Aerococcus spp., the incidence of infections with this species has probably been underestimated.

More rarely cases of bacteremia/septicemia … Aerococci have often been misidentified as streptococci in microbiology laboratories, leading to an underestimation of these bacteria as causes of human infections. An increased awareness of aerococci and the introduction of matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF MS), has lead to an increased isolation of Aerococcus urinae and Aerococcus Posts about Aerococcus urinae; written by FA Manian MD, MPH.

The aerococcal isolates displayed low MICs for ampicillin, cefalotin, mecillinam, and nitrofurantoin. Most A. sanguinicola isolates were resistant to ciprofloxacin, whereas most A. urinae isolates had low MICs. Clinical studies are needed to establish clinical breakpoints and optimal treatment.
