What is the primary purpose of virus quantification?
What is the primary purpose of virus quantification?
- To determine the shape and structure of viruses
- To count the number of viruses in a specific volume and determine virus concentration (correct)
- To identify the genetic sequence of viruses
- To observe virus interactions with host immune cells
The virus titer is defined as:
The virus titer is defined as:
- The number of viruses that do not infect cells
- The lowest concentration of viruses that still infects cells (correct)
- The genetic material concentration of a virus
- The number of virus particles that bind to host cells
Which of the following statements correctly differentiates biological and physical viral quantification tests?
Which of the following statements correctly differentiates biological and physical viral quantification tests?
- Biological tests depend on viral replication, while physical tests do not require viral activity (correct)
- Physical tests determine viral infectivity, while biological tests count all viral particles
- Both tests measure virus infectivity directly
- Biological tests count viral particles, while physical tests rely on cell cultures
