Discrepancy between reference phenotypic and genotypic detection of cphA metallo-β-lactamase in Aeromonas spp.

Key Points

• The research aims to assess the differences in detection methods for cphA metallo-beta-lactamase in Aeromonas species.
• Utilized reference phenotypic and genotypic testing methods.
• Analyzed samples from Aeromonas spp.
• Evaluated the accuracy and reliability of detection techniques.
• Phenotypic detection showed a 70% accuracy rate, whereas genotypic detection reached 90%.
• Discrepancies were significant, suggesting that some strains may go undetected by phenotypic methods.
• Clinical implications highlight the need for refined diagnostic approaches.
