53Microbes Are Genetically Modified by
- A natural event
- Unintended result of experiments
- Malicious manipulation
-
54Resistant bacterial infections a public
health problem with global security implications
55Microbial Development of Resistance Natural Event
Antimicrobial drugs in the environment pressure
microbes to develop resistance
Chromosomal mutations transpositions
MICROBE
Extra-chromosomal plasmid acquisition
RESULT Development of drug-resistant strains
56Malicious Manipulation
Not easy
- Pathogenicity or other characteristics, such as
stability, may be compromised when multi-drug
resistance is deliberately engineered. - Soviet researchers failed to design
environmentally stable virulent
multi-drug-resistant strains of tularemia
plague.
but still a concern
Designing new or modified virulent pathogens
that could evade drugs current vaccines may be
possible with new, sophisticated technologies.
57Malicious Manipulation Potential Impact
- Drug resistance
- Virulence
- Environmental stability
- Dissemination potential
- Ease of Replication
- Ability to Detect
- Effectiveness of Countermeasures
Note Possibility of new chimeric organisms

59NRC Report on Dual Use Research
Report of the National Research Council of the
National Academies Biotechnology Research in
an Age of Terrorism Confronting the Dual Use
Dilemma (October 2003)
60NRC Criteria for Experiments of Concern
- Demonstrate how to render a vaccine ineffective
- Confer resistance to therapeutically useful
antimicrobials - Confer pathogenicity or enhance the virulence of
a pathogen - Increase transmissibility of a pathogen
- Alter the host range of a pathogen
- Enable evasion of diagnostic/detection modalities
- Enable weaponization of a biological agent or
toxin
61Gene Mutation Leads to Super-Virulent Strain of
TBUC Berkeley Press December 9, 2003
- Disabling a set of virulence genes led to a
more deadly form of TB - Results were completely unexpected
62Bioterror Researchers Build a More Lethal
MousepoxNew York Times November 1, 2003
- Gene that suppresses immune system added to
mousepox virus (close relative to smallpox) - Killed all mice, even vaccinated ones or those
treated with antivirals - A combination therapy was protective
- Effort to learn how to combat genetically
engineered smallpox
63Synthetic Polio Virus Made from Mail-Order
KitsCELL July, 2002
- Scientists synthesized entire polio genome using
readily available reagents and well-established
molecular biology techniques - Synthetic virus was infectious, capable of
replication, and pathogenic. - In vitro synthesis took 3 years to complete
- Application could lead to benefits for medicine,
such as rebuilding other viruses in a weakened
form to help devise vaccines.
64Nature News November 14, 2003
Virus Built from Scratch in Two WeeksNew
method accelerates prospect of designer microbes
- Scientists made Phi-X virus, a harmless
bacteriophage, in 2 weeks from commercially
available ingredients - Virus was fully functional
- New method a step toward new lifeforms to clean
up toxic waste, secrete drugs, produce fuel

71Rad/Nuc Event Planning Challenges
- Dirty bomb
- Small affected population
- Low level exposure
- Limited tools for isotope identification,
dosimetry - Long-range susceptibility to cancer
- Small scientific community
- Improvised nuclear device attack on nuclear
facility - Large affected population
- High level exposure
- Acute radiation syndrome, blast injuries,
hematopoietic and GI syndromes - Triage vs. medical care treatment pre- or
post-exposure -
72- Today, terrorist organizations have access to
nuclear material which could produce a crude
weapon with a yield of 0.01 kt to 20 kt in
size. - Hiroshima 12.5 kt
73Health Consequences of a 1 kt Nuclear Bomb (4 Gy
exposure zone)
- 1 Gy Nausea and vomiting in 10 within 48 hr of
exposure - 2 Gy Nausea and vomiting in 50 within 24 hr of
exposure marked decrease in WBC and platelet
counts - 4 Gy Nausea and vomiting in 90 within 12 hr,
diarrhea in 10 within 8 hr 50 mortality in the
absence of medical care - 6 Gy 100 mortality within 30d in the absence of
medical care, due to BM failure
