Study Notes

Quantitative Susceptibility Testing

  • Necessary for patients who fail to respond to antimicrobial therapy or relapse during therapy
  • Targets accuracy and communication as goals

Importance of Susceptibility Testing

  • Crucial for effective management of infectious diseases
  • Ensures high-quality results for informed antimicrobial therapy
  • Overcoming challenges of increasing bacterial resistance and limited laboratory resources

Definition of Antimicrobial Agents

  • Clinically significant organisms
  • Natural, semisynthetic, or synthetic molecules used to treat or prevent disease
