2015-09-28 · 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.

Most Aerococcus species will grow in Salt Broth but A. sanguinicola is the only species that is usually Bile Esculin (+). 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 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). Although for many years Aerococcus urinae was considered a urinary contaminant, increasingly it is recognized as an emerging pathogen capable of causing not only urinary tract infection (UTI) but also secondary bacteremia and endocarditis, among others. 1 Aerococci urinae is a Gram-positive, catalase-negative, bacterium that grows in clusters, often appearing in colonies that resemble Streptococci viridans [ 1 ]. Its genus was first described in 1953, with the first reported case of A. urinae in a human described in 1992 [ 1, 2 ].

Due to increasing antibiotic resistance, urine culture should include antibiotic susceptibility testing. Prompt and culture-specific treatment is critical to avoid clinical progression of the infection. 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. In complicated UTI, ampicillin is probably a safe treatment option, whereas nitrofurantoin is probably effective in uncomplicated UTI. Treatment studies in aerococcal infections are needed as is a better understanding of the natural niches for aerococci and the pathogenesis and clinical course of aerococcal infections. Se hela listan på antimicrobe.org Nitrofurantoin was most commonly prescribed, achieving clinical and microbiological success in 71/76% of cases of A. urinae UTI, and 42/50% of cases of A. sanguinicola UTI. Pivmecillinam achieved success in patients with A. urinae cystitis and ciprofloxacin in patients with pyelonephritis.

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.

•Erwinia herbicola Enterobacter agglomerans Pantoea agglomerans •Alfa (viridans) streptokocker Streptococcus mitis Aerococcus urinae is an uncommon urinary tract pathogen that causes infections predominately in elderly people with local or general predisposing conditions, such us malignancy, prostatic diseases, diabetes mellitus, dementia. 2016-01-01 1997-12-01 Nitrofurantoin är ett av två förstahandsmedel för UVI-behandling i Sverige. Det andra medlet, pivmecillinam, gavs endast till sex patienter med A. urinae men med bra effekt. Ett annat antibiotikum, ciprofloxacin, som vanligtvis ges till patienter med mer komplicerade urinvägsinfektioner (t.ex.

Both species have worldwide been associated with urinary tract infections especially in elderly predisposed patients. Fig. 1 Upper part of the figure shows a blood isolate of Aerococcus urinae grown for 24 h on blood agar in 5% CO 2. The small colonies with clear α-haemolysis can be seen. Lower part of the panel shows a blood isolate of Aerococcus sanguinicola grown on the same plate.

Aerococcus urinae is a newcomer in clinical and microbiological practice, causing urinary tract infections, bacteraemia/septicaemia and/or endocarditis. This study presents for the first time an evaluation of the activity of a representative panel of antibiotics against a large number of A. urinae isolates. Background Aerococcus urinae is a Gram-positive organism, initially identified in 1992. It is known to cause urinary tract infections (UTIs), bacteremia, and endocarditis in humans. There is limited data regarding the susceptibility of A. urinae to first-line antimicrobials indicated for the treatment of UTIs. Aerococcus urinae (A.urinae) is a rare bacterium that can occur in a urinary tract infection, infective endocarditis, blood stream, and spinal disc infections.
