Area of Science:

  • Microbiology
  • Genomics
  • Drug Discovery

Background:

  • Advances in microbial genome sequencing and functional genomics have enabled the identification of numerous virulence genes in Gram-positive bacteria.
  • These virulence genes represent a diverse set of potential targets for novel antimicrobial therapies.

Purpose of the Study:

  • To review the contribution of two key functional genomics technologies to the identification of virulence genes in Gram-positive pathogens.
  • Focus on in vivo expression technology (IVET) and signature-tagged mutagenesis (STM).

Main Methods:

  • In vivo expression technology (IVET) for monitoring gene expression within a host.
  • Signature-tagged mutagenesis (STM) for genetic screening of virulence factors.
