A. viridans isolates were commonly susceptible to-lactam antimicrobials and exhibited a great genetic 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. Embolization is frequently reported with Aerococcus urinae … 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 Since Aerococcus sanguinicola was designated as a species in 2001, only a few cases of bacteremia have been reported.

The objective of this study was to evaluate three methods for susceptibility testing of A. urinae and A. sanguinicola using EUCAST media. Aerococcus sanguinicola is a cause of urinary tract infections, blood stream infections, and infective endocarditis (IE).

Bacteremia with Aerococcus sanguinicola: Case Series with


Answer: Aerococcus sanguinicola DISCUSSION Species belonging to the genus Aerococcus are isolated from the urine and blood of elderly patients with underlying illnesses, such as diabetes, heart disease, or urological conditions. They are facultatively anaerobic GPCs arranged in pairs, tetrads or irregular clusters, catalase and oxidase (-). Aerococcus urinae and Aerococcus sanguinicola are relatively newcomers and emerging organisms in clinical and microbiological practice. Both species have worldwide been associated with urinary tract infections. More rarely cases of bacteremia/septicemia and infective endocarditis have been reported. Treatment options are therefore important.
Johann schäffer

A. urinae och A.sanguinicola förekommer vid urinvägsinfektion, septikemi, endokardit och meningit. A. viridans förekommer vid urinvägsinfektioner om predisponerande faktorer finns.

The mean patient age was 82 (range 24-101) years. Se hela listan på antimicrobe.org Species belonging to the Aerococcus genus are isolated from the urine and blood of elderly patients suffering from urinary tract infections (UTIs). However, the clinical significance, phenotypic features and antimicrobial susceptibilities of these underestimated and/or misidentified species remain unclear. Aerococcus urinae and Aerococcus sanguinicola: Susceptibility Testing of 120 Isolates to Six Antimicrobial Agents Using Disk Diffusion (EUCAST), Etest, and Broth Microdilution Techniques Derya Carkaci, Xiaohui Chen Nielsen, Kurt Fuursted, Robert Skov, Ole Skovgaard , Emilio Perez Trallero, Reto Lienhard, Jenny Åhman, Erika Matuschek, Gunnar Kahlmeter, Jens Jørgen Christensen We identified 64 Aerococcus urinae isolates and 40 Aerococcus sanguinicola isolates, which correlates with an incidence of 33 cases of aerococcal bacteriuria per 100,000 inhabitants per year. The median age was 83years for all patients with aerococcal bacteriuria, which was significantly higher than for patients with Escherichia coli or Enterococcus faecalis bacteriuria.
