Insights

This study details methods for infecting mice with murine cytomegalovirus (mCMV). It includes protocols for virus propagation, preparing virulent strains, and quantifying viral load using plaque-forming cell assays.

Area of Science:

  • Virology
  • Immunology
  • Animal Models

Background:

  • Murine cytomegalovirus (mCMV) is a significant pathogen in research settings.
  • Understanding mCMV infection dynamics is crucial for developing effective countermeasures.
  • Standardized protocols are needed for consistent mCMV research.

Purpose of the Study:

  • To describe standardized procedures for infecting mice with mCMV.
  • To provide methods for mCMV propagation and preparation of virulent strains.
  • To detail a plaque-forming cell (PFC) assay for viral quantification.

Main Methods:

  • Infection of newborn and adult mice with mCMV.
  • Propagation of mCMV in cell cultures.
  • Preparation of virulent mCMV from infected mouse salivary glands.
  • Murine embryonic fibroblast preparation.
  • Plaque-forming cell (PFC) assay for mCMV titration.

Main Results:

  • Established protocols for successful mCMV infection in mice.
  • Demonstrated methods for generating high-titer mCMV stocks.
  • Validated the PFC assay for accurate measurement of mCMV titers.

Conclusions:

  • The described procedures provide a robust framework for mCMV research.
  • Standardized methods facilitate reproducible studies on mCMV pathogenesis and immunity.
  • Accurate viral quantification is essential for evaluating antiviral strategies.
