This presentation touches on the lilmitations of the VITEK 2 systems in conducting microbial identification and Antimicrobial susceptibility testing.

1. Understanding the Limitations of the Vitek 2 System in Microbial Identification and Antimicrobial Susceptibility Testing (AST ) By Egah not AGAR Ruth Grace 1/11/2023

2. Introduction: Understanding Vitek 2 System Limitations In clinical microbiology, accurate and timely identification of microbial pathogens and their susceptibility to antibiotics is crucial for effective patient care.

3. What is the Vitek 2 system? overview The Vitek 2 System is an automated platform used in clinical microbiology for microbial identification and AST

4. Microbial identification limitations Rare or Emerging Pathogens The Vitek 2 system relies on a predefined database for microbial identification. However, this database may not always include rare or emerging pathogens. When faced with microorganisms not in the database, Vitek 2 may struggle to provide accurate identification. T herefore, it becomes important to verify results with additional methods False Identifications

6. Limitations in Antimicrobial Susceptibility Testing (AST) Antimicrobial Susceptibility Testing (AST) using the Vitek 2 system is a valuable tool in clinical microbiology, but it has several limitations that should be considered. Here are some common limitations associated with AST testing using Vitek 2 The AST panel of the Vitek 2 system may not include all antibiotics used in clinical practice.

7. Limitations in Antimicrobial Susceptibility Testing (AST) The Vitek 2 system may not allow for easy customization of the AST panel. The system may not effectively detect certain resistance mechanisms, particularly those associated with novel or emerging resistance patterns. In some cases, the Vitek 2 system may yield "indeterminate" results for certain antibiotics. The Vitek 2 system is not the fastest method for AST. It may take several hours to days to obtain results, which can be a limitation in cases where rapid decision-making is crucial.

8. Limitations in Antimicrobial Susceptibility Testing (AST) Accurate interpretation of Vitek 2 results can sometimes be complex, particularly when dealing with multidrug-resistant organisms. R efer to pdf file It's important for clinical microbiologists and healthcare professionals to be aware of these limitations and to complement Vitek 2 AST results with additional testing and clinical judgment when necessary to ensure the best patient care and treatment decisions.
