Inhibition of Lancefield group D enterococci by contamination of a commercial identification medium with paraffins
Journal of Clinical Microbiology
|December 1, 1980
Abstract:
A commercially available system for the identification of streptococci was found to incorrectly identify group D enterococci due to contamination of the 6.5% NaCl medium with paraffins.
Insights
A commercial streptococci identification system misidentified group D enterococci. This occurred because the 6.5% NaCl medium was contaminated with paraffins, impacting bacterial identification accuracy.
Area of Science:
- Microbiology
- Clinical Diagnostics
Background:
- Accurate identification of streptococci is crucial for clinical diagnostics and treatment.
- Group D enterococci are a significant group of streptococci with distinct clinical implications.
Purpose of the Study:
- To investigate the cause of misidentification of group D enterococci by a commercial streptococci identification system.
Main Methods:
- Evaluation of a commercially available streptococci identification system.
- Analysis of the 6.5% NaCl medium for contaminants.
Main Results:
- The commercial system incorrectly identified group D enterococci.
- Contamination of the 6.5% NaCl medium with paraffins was identified as the cause.
Conclusions:
- Paraffin contamination in the 6.5% NaCl medium can lead to inaccurate identification of group D enterococci.
- Quality control of diagnostic media is essential for reliable bacterial identification.
