Eliminating the threat of terrorist or criminal attacks with microorganisms or toxin weapons is a continual challenge for biodefense and biosecurity programs. The task is difficult for several reasons: (1) the relative ease of access to a variety of effective source materials (Srivatsan et al., 2. At the onset of an event, it may be difficult to distinguish between a deliberate attack and a naturally occurring outbreak of an infectious disease (Morse and Budowle, 2. Morse and Khan, 2. Activate Windows 7 Chew Wga 13whamEven if evidence strongly supports the hypothesis of a deliberate attack, it may still be very difficult to attribute the attack with certainty to those responsible (i. Attempts to resolve the crime will require advanced methods for characterizing microbial agents, as well as a combination of traditional investigation and intelligence gathering activities. The Approach. In response to the need to determine the nature of the threat and the source of the weapon and to identify those who perpetrated the crime, the scientific community rose to the occasion beginning in 1.

A service of the National Library of Medicine, National Institutes of Health. Institute of Medicine (US) Forum on Microbial Threats. Microbial forensics is the scientific discipline dedicated to analyzing evidence from a bioterrorism act, biocrime, hoax, or inadvertent microorganism/toxin release for attribution purposes (Budowle et al., 2. Köser et al., 2. 01. Morse and Budowle, 2. Another goal can be to support analysis of potential bioweapons capabilities for counter- proliferation, treaty verification, and/or interdiction. A forensics investigation initially will attempt to determine the identity of the causal agent and/or source of the bioweapon in much the same manner as in an epidemiological investigation. The epidemiological concerns are identification and characterization of specific disease- causing pathogens or their toxins, their modes of transmission, and any manipulations that may have been performed intentionally to increase their effects against human, animal, or plant targets (Morse and Budowle, 2. Morse and Khan, 2. A microbial forensics investigation proceeds further in that evidence is characterized to assist in determining the specific source of the sample, as individualizing as possible, and the methods, means, processes, and locations involved to determine the identity of the perpetrator(s) of the attack or to determine that an act is in preparation. A systems analysis may be able to determine the processes used to generate the weapon or how it was delivered, which also can help inform the investigation and attribution decision. The ultimate goal is attribution—to identify the perpetrator(s) or to reduce the potential perpetrator population to as few individuals as possible so investigative and intelligence methods can be effectively and efficiently applied to “build the case” (Figure A1- 1). The microbial forensics attribution continuum. Forensic Targets. Microbial forensic evidence may include the microbe, toxin, nucleic acids, protein signatures, inadvertent microbial contaminants, stabilizers, additives, dispersal devices, and indications of the methods used in a preparation. In addition, traditional types of forensic evidence may be informative and should be part of the toolbox of potential analyses of evidence from an act of bioterrorism or biocrime. Traditional evidence includes fingerprints, body fluids and tissues, hair, fibers, documents, photos, digital evidence, videos, firearms, glass, metals, plastics, paint, powders, explosives, tool marks, and soil. Other types of relevant evidence must be considered to exploit avenues to better achieve attribution, including proteins and chemical signatures. These types of signatures can only be obtained from crimes where the weaponized material or delivery device is found; they have little use in covert attacks where the biological agent is derived from the victims. Many of these methods are based on sound technologies and are complementary. They can be combined to identify signatures of sample growth, processing, and chronometry (Morse and Budowle, 2. Matching of sample properties can help to establish the relatedness of disparate incidents. Furthermore, mismatches might have exclusionary power or signify a more complex causal relationship between the events under investigation. The results of these analyses can provide information on how, when, and/or where microorganisms were grown and weaponized. While the goal of a microbial forensic analysis is to characterize a sample such that it can be traced to a unique source or at least eliminate other sources, it is unlikely that microbial forensic evidence alone is currently adequate to meet this goal. Emerging Science and Technology. To enhance attribution capabilities with microbial evidence, considerable attention is being invested in molecular genetics, genomics, and bioinformatics. These fields are essential to microbial species/strain identification, fine genome variation, virulence determination, pathogenicity characterization, possible genetic engineering, and attaining source attribution to the highest degree possible. The various tools that have been, or are being, developed in these areas will help to narrow the potential sources from which the pathogen used in an attack may have originated. Indeed, sequencing of an entire genome has been demonstrated as feasible in epidemiological investigations, such as the recent studies of outbreaks of E. O1. 04: H4 in Germany and cholera in Haiti (Brzuszkiewicz et al., 2. Chin et al., 2. 01. Grad et al., 2. 01. Hasan et al., 2. 01. Hendriksen et al., 2. Mellmann et al., 2. Rasko et al., 2. 01. Rohde et al., 2. 01. In addition, metagenomics studies may become foundational on describing diversity and endemicity. Endemicity becomes important when the relationship between microbes or their genetic residues in samples collected from a site of interest and microbes in the environmental background need to be defined. While the inferential capacity of microbial forensics genetics has yet to reach its full power, the phenomenal new generations of sequencing technology and the concomitant developments for bioinformatics capabilities to handle and extract the explosion of data offer potentials for enhancing microbial forensic investigations. Indeed, the science and technology supporting microbial forensics are advancing at an inconceivable rate. For example, in 2. TIGR (Budowle et al., 2. NRC, 2. 00. 9; Ravel et al., 2. Read et al., 2. 00. That seemingly nominal analysis, by today’s capabilities, cost approximately $2. Today, such enterprises are a fraction of the cost (and continue to drop dramatically), are becoming more automatable, and provide gigabases and terabytes of data in a matter of days (Bentley et al., 2. Holt et al., 2. 00. Loman et al., 2. 01. Mac. Lean et al., 2. Margulies et al., 2. Given the enhanced capabilities of nucleic acid sequencing of microbes the microbial forensics community will embrace these molecular tools. Although developments are needed, one can envision identification of microbes at the species, strain, and isolate levels being transformed using next- (or better termed “current- ”) generation sequencing (CGS). Fine genome detail could become available for routine microbial forensic use. Because CGS provides whole genome characterization capabilities with high depths of coverage (1. Indeed, whole genome sequencing will reduce the need for a priori design of assays directed at defined species. The technology should apply at some resolution level to any genome without knowledge of the target. In addition, whole genome sequencing offers the capability to evaluate a sample for indications of genetic engineering. Current Realities. However, not all microbial forensic evidence will present itself in a manner where copious quantities of target are available. Some samples will be highly degraded and/or contaminated. Thus, there will be challenges to extract the most information possible from limited materials and non- viable organisms.
