Summary
Aerococcus urinae is a pathogenic bacterium found in urine samples. Microbiological labs should identify this organism, with ampicillin or nitrofurantoin recommended for treatment.
Area of Science:
- Clinical microbiology
- Bacteriology
Context:
- Alpha-haemolytic streptococci in urine are common but their significance is often unclear.
- Aerococcus urinae is a pathogenic species within this group.
Purpose:
- To determine the prevalence and antibiotic susceptibility of Aerococcus urinae in urine samples.
- To describe appropriate methods for identification and resistance determination.
Summary:
- A prospective study identified Aerococcus urinae in 7 of 27 alpha-haemolytic streptococcal isolates (0.3% of all urine isolates).
- Methods for accurate identification and antibiotic resistance testing are presented.
Impact:
- Highlights the importance of identifying Aerococcus urinae in clinical microbiology laboratories.
- Recommends ampicillin and nitrofurantoin as effective treatments for Aerococcus urinae infections.
