Common Pitfalls

• Pitfall: Misinterpreting ResFinder results by overlooking gene variants or incomplete matches can lead to inaccurate resistance predictions. Always cross-check findings with literature and use high-quality genome assemblies to improve accuracy.
• Pitfall: Confusing intrinsic and acquired resistance mechanisms may result in incorrect assumptions about transmission potential. Remember that intrinsic resistance is species-specific, while acquired resistance spreads via mobile genetic elements.
• Pitfall: Neglecting quality control in virtual AST exercises can undermine data reliability. Always include control strains and adhere to standardized protocols to ensure results are valid and reproducible.
• Pitfall: Overlooking the importance of breakpoints in susceptibility interpretation may lead to clinical misclassification. Familiarize yourself with EUCAST or CLSI standards to correctly categorize isolates as resistant, intermediate, or susceptible.
• Pitfall: Assuming PCR detection alone confirms phenotypic resistance can be misleading. Some genes are silent or poorly expressed, so molecular detection must be correlated with phenotypic testing when possible.
• Pitfall: Failing to document bioinformatics parameters (e.g., % identity, coverage thresholds) may reduce reproducibility. Always record settings used in ResFinder to allow verification and peer review of results.
• Pitfall: Rushing through the final assessment without reviewing all modules can result in gaps in integrated knowledge. Allocate time to revisit key concepts in resistance mechanisms and AST interpretation before attempting the exam.
