Overview
This article presents a method for detecting the bacterial pathogen Yersinia pestis using genetically engineered reporter phage. These phage can transduce a bioluminescent signal in response to their specific host, allowing for rapid identification of the pathogen.
Key Study Components
Area of Science
- Microbiology
- Pathogen Detection
- Genetic Engineering
Background
- Yersinia pestis is the causative agent of plague.

What is Yersinia pestis?
Yersinia pestis is a bacterium that causes plague, a serious infectious disease.
How does the reporter phage work?
The reporter phage transduces a bioluminescent signal in response to the presence of its specific host.
Why is detecting Yersinia pestis important?
Early detection is crucial for preventing outbreaks and addressing bioterrorism threats.
What are category A pathogens?
Category A pathogens are those that pose the highest risk to national security and public health.
What role does bacterial luciferase play?
Bacterial luciferase is responsible for the bioluminescent signal that indicates the presence of the pathogen.
Can this method be used for other pathogens?
Yes, the approach may be adapted for detecting other bacterial pathogens.
