Summary
Aerococcus-like organisms have been identified in Danish hospitals, potentially causing urinary tract infections. Further analysis suggests these bacteria may represent a distinct taxonomic group.
Area of Science:
- Clinical Microbiology
- Bacteriology
- Taxonomy
Background:
- Aerococcus-like organisms have been intermittently isolated from urinary tract specimens in hospitalized patients.
- Clinical data suggests a potential role for these organisms in urinary tract infections.
Purpose of the Study:
- To investigate the prevalence and characteristics of Aerococcus-like organisms in urinary tract infections.
- To determine if these isolates represent a distinct bacterial taxon.
Main Methods:
- Isolation and identification of Aerococcus-like organisms from urine specimens.
- Phenotypic characterization of 73 bacterial strains (63 new, 10 historical).
- Comparison with known gram-positive, catalase-negative cocci and coccobacillary organisms.
Main Results:
- Aerococcus-like organisms were isolated from patients with suspected urinary tract infections across seven Danish clinical microbiology departments.
- One strain (NCTC 12142) is available in a type culture collection.
- Phenotypic analysis indicates these strains may constitute a separate taxon.
Conclusions:
- Aerococcus-like organisms are found in urinary tract infections in Denmark.
- These findings support the classification of these isolates as a distinct bacterial taxon.
