Which of the following methods is used for rapid bacterial identification based on protein profiles?
Understand the Problem
The question asks to identify the method used for rapid bacterial identification based on protein profiles from a list of options. The options include disk diffusion, Gram staining, PCR, and MALDI-TOF MS. The question requires knowledge of microbiology and techniques used in bacterial identification.
Answer
MALDI-TOF MS
Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) is used for rapid bacterial identification based on protein profiles.
Answer for screen readers
Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) is used for rapid bacterial identification based on protein profiles.
More Information
MALDI-TOF MS is a rapid and sensitive method that identifies bacteria by analyzing their protein profiles. It is now a routine resource in clinical microbiology because of its speed and reliability in microorganism identification.
Tips
A common mistake is confusing MALDI-TOF MS with other identification methods like PCR or genotypic techniques. MALDI-TOF MS specifically analyzes protein profiles for rapid identification.
