Microbial Forensics – An Upcoming Investigative Discipline

Microorganisms make good weapons and bioterorism has been known to exist since centuries. This has most recently been highlighted by the terrorist attack using anthrax in the fall of 2001 in U.S. Although such attacks of bioterrorism are few, forensic evidence to criminally prosecute the perpetrator is necessary. To strengthen defence against bio crimes, a comprehensive technological network involving various fields needs to be developed. Microbial forensics is one such new discipline combining microbiology and forensic science. It uses advanced molecular techniques like microarray analysis and DNA fingerprinting etc. to associate the source of the causative agent with a specific individual or group by measuring variations between related strains. High quality assurance and quality control standards for microbial forensics will ensure highly reliable results that will stand up in the court of law. The more precise and refined a microbial system becomes, the more proper guidelines for investigations will be defined. An integrated approach towards developing this field of microbial forensics needs to be followed, to meet the challenges of bioterrorism more effectively.
