Study Notes
Molecular Testing
- The analyte for molecular testing is the genetic material (DNA or RNA) of an organism, in contrast to the analysis of phenotypic traits which are the physical and behavioral characteristics of an organism.
Molecular Epidemiology
- The purpose of molecular epidemiology in outbreak situations is to identify the source and track the spread of an infectious disease by analyzing the genetic material of the causative agent.
Targeted Microorganisms
- Some microorganisms are targeted by molecular-based laboratory tests because they are difficult to culture, require specialized growth conditions, or have a fastidious nature, making it hard to detect them using traditional methods.
Nucleic Acid Amplification
- The focus of nucleic acid amplification methods in detecting antimicrobial resistance is to identify specific genetic mutations associated with resistance to certain antibiotics, allowing for targeted treatment and effective infection control.

Description
Test your knowledge of detection and identification of microorganisms using molecular-based laboratory tests. This quiz covers the common targets for molecular-based tests, advantages and disadvantages of molecular-based methods compared to traditional culture-based methods, and differentiation between organisms for which nucleic acid-based tests are available.
