Area of Science:

  • Microbiology
  • Molecular Biology
  • Bioforensics

Background:

  • Accurate detection of biological warfare agents is vital for national security.
  • Characterizing indigenous microbial populations is essential for identifying foreign agents in environmental samples.

Purpose of the Study:

  • To create region-specific genetic fingerprints of microbial flora in environmental air samples.
  • To establish a baseline for rapid discrimination of potential biological warfare agents.

Main Methods:

  • Analysis of environmental air samples using polymerase chain reaction (PCR).
  • Employing temporal temperature gradient electrophoresis (TTGE) to generate microbial genetic fingerprints.
  • Data compilation including meteorological information for comprehensive analysis.
