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.

Commercial ID systems have limited abilities to ID A. urinae/A. viridans and will not recognize A. sanguinicola. The most distinguishing characteristic of Aerococcus sp. is their gram stain morphology of large GPCs in Aerococcus spp.

Aerococcus urinae may cause urinary tract infections, bacteremia, and endocarditis. No standardized susceptibility test methods or interpretive criteria have been proposed for this organism. This study reports the MIC results for 128 A. urinae isolates tested by broth microdilution.

Se hela listan på antimicrobe.org A retrospective chart review was performed on 92 patients from whom 118 isolates of Aerococcus sanguinicola (n = 52) or Aerococcus urinae (n = 66) were obtained from urine cultures between October 2007 and June 2008 to assess clinical presentation and antimicrobial susceptibilities. The study found that nitrofurantoin (Macrobid), pivmecillinam (Selexid) and ciprofloxacin (Cipro) were effective antibiotic treatments for UTIs caused by aerococcus. Some background UTIs are a common problem that can be caused by different bacteria. 2018-10-01 · There are no studies on the recommendations for the antibiotic treatment of A. sanguinicola, but the genus Aerococcus is fairly sensitive to beta-lactams and vancomycin.

Aerococcal infections - from bedside to bench and back

Prior to the description of the new species, Aerococcus viridans was the only non-chain-forming GPC that was pyrrolidonylarylamidase (PYR) positive and leucine aminopeptidase (LAP) negative. Several antibiotics, including nitrofurantoin and amoxicillin, could serve as treatment options. Resistance against ciprofloxacin was recorded, especially in A. sanguinicola isolates. In a retrospective population-based study on aerococcal bacteremia, 77 cases were identified during a three-year period (A. urinae n=49, A. sanguinicola n=13, A. viridans n=14 and A. christensenii n=1). Aerococcus urinae is a member of the bacterial genus Aerococcus. The bacterium is a Gram-positive, catalase-negative coccus growing in clusters.

Interestingly, it shares characteristics with Streptococci, Staphylococci, and Enterococci.

MICs to erythromycin and levofloxacin were ≥0.5 and >4 μg/mL in 41% and 78% of A. sanguinicola and 17% and 23% of A. urinae isolates, respectively. Introduction. During the past decade the clinical relevance of various catalase-negative, Gram-positive cocci has received much attention. 1 Among these, Aerococcus urinae is a newcomer in clinical and microbiological practice, first reported in 1989 2 and designated in 1992. 3 A. urinae isolates were originally recognized by their cell morphology (Staphylococcus-like in Gram's stain) and Keywords: Aerococcus, Aerococcus sanguinicola, Aerococcus urinae, antibiotic treatment, infective endocarditis, urinary tract infection Article published online: 8 October 2015 Corresponding author: M. Rasmussen, Department of Clinical Sciences Lund, Division of Infection Medicine, Tornavägen 10, BMC B14, SE-221 84 Lund, Sweden Almost 80 % of patients with aerococcal bacteruria had symptoms of a urinary tract infection. Several antibiotics, including nitrofurantoin and amoxicillin, could serve as treatment options.

Aerococcus urinae was first recognized as a separate species in 1992 . Its normal habitat remains unclear. Interestingly, it shares characteristics with Streptococci, Staphylococci, and Enterococci. I vissa nordiska länder används mecillinam även i enstaka fall vid komplicerad UVI (övre urinvägsinfektioner). Klinisk evidens är otillräcklig, varför EUCAST-brytpunkter för denna indikation saknas. group of antibiotics [4,6]. Aerococcus urinae is found in the urinary tract and most, but not all, studies implicate A. urinae as a pathogen in uri-nary tract infections [1,2,4,7,8].

Patients often only start to feel better if given active antibiotics such as Amoxicillin or Nitrofurantoin.
