title: Comparison of two systems for identification of anaerobic bacteria.
abstract: The RapID Ana and the API 20A systems for identification of anaerobic bacteria were compared for accuracy on 108 recent isolates of gram-negative and gram-positive anaerobic bacteria. No additional tests or gas-liquid chromatography were used. RapID Ana identified 91.7% of the isolated strains to species level and 6.5% to genus level but failed to identify 1.8% of the total strains. API 20A identified 85.2% of strains to species level, 3.7% to genus level but failed to identify 11.1% of the total strains. Although the difference between the identification rates of the two systems was not significant, it was concluded that RapID Ana was easier to perform and interpret.
