The Athena Project security system utilizes several components
to detect the presence of pathological agents. Each site hosting
an Athena system would be equipped with monitoring devices, which
detect pathogens by means of nucleic acid analysis. Data obtained
by the detecting devices would be reported to a centralized location,
where it would be assessed compared to previously acquired "control"
readings. From this location, assistance could be sent and the authorities
could be notified.
Detection systems use a variety of methods to identify
the presence of pathogens in a matter of minutes. Many detection
devices are still works in progress. The overall detection system
must involve the integration of several key parts. For one, a device
that offers real-time detection of pathogens is needed. We believe
that the Advanced
Nucleic Acid Analyzer would be one of the best devices because
it can analyze samples on the scene within 15 minutes. The HANAA,
(a hand held ANAA) is the
first man-portable, handheld, real-time PCR biodetection instrument
ever made. It can simultaneously test four different samples for
two different DNA sequences and report the results in real time.
Unfortunately, this product is not yet commercially available as
it is constantly being tested and improved. Nine prototype units
are currently undergoing testing by evaluators, including the CDC.
We believed this was the best device to use until we discovered
some of its drawbacks. Samples that are used to analyze must be
liquefied and free of PCR inhibitors. This device cannot work alone
because an additional device is needed to obtain air samples and
to convert the particles into liquid form.
However,
a different detection system is also construction that is able to
incorporate both the aspects of air sampling and pathogen detection.
This device is known as the Autonomous
Pathogen Detection System (APDS). It can continuously monitor
multiple airborne biological threat agents in the environment and
is specifically designed for use in places in which a large number
of people are at high risk to exposure of bioterrorism. According
to the Lawrence
Livermore National Laboratory, which develops APDS, "The
APDS is completely automated, offering aerosol sampling, in-line
sample preparation fluidics, multiplex flow cytometer detection
and identification assays, and orthogonal, flow-through PCR (nucleic
acid) amplification and detection." Although this system can
apparently be deployed without any need for technicians to be on-hand,
there are a few drawbacks. A device such as this, which integrates
several different components into one system, is as large as a refrigerator.
This system may eventually be compacted so that it will be more
practical for use in some spaces. Additionally, this system is not
commercially available either and is still undergoing tests for
improvements. However, at this point in time, it seems to be the
best choice for implementing a detection system. Moreover, some
of the drawbacks of the system can be cleverly worked around. For
example, a large urn could mask the large detection system that
connects itself to ventilation units in malls.
Example Application of the Athena Project: Malls
As
an example application of the Athena Project, we will demonstrate
our security system in a mall complex. Our system should be adapted
to airports and other public places where bioterrorism is a threat.
We believe these places could consist of places of mass gathering
including train stations, schools, conventions, stadiums, and office
complexes.
New malls built with the Athena project in mind should be partitioned
into several compartments with the ability to section off different
parts of the mall. Also, the ventilation system of the mall should
be designed so that it can partition off contaminated areas to prevent
the further spreading of pathogens. In malls currently standing,
where air is recycled and special partitions are not currently in
place, a series of detectors can still be used at the present air
intake locations. Folding partitions can be installed in case of
an emergency.
The APDS should be placed throughout the mall complex's air circulation
system, one each at the ends of the vents it is connected to. Before
completely installing our system of APDS, a measurement of the air
quality must be taken and used as a comparison for future samples.
If more than one of our APDS detect the presence of a lethal pathogen,
an alarm will go off. A measurement can be taken which will be used
to determine the extent of the contamination. This alarm will include
an electrical signal that will be relayed from the devices to the
headquarters of the mall security, as well as the closest emergency
response center. The events that take place after the alarm goes
off are specific to the situation and location. We have identified
possibilities for what could happen after the detection, but they
are not absolute, fixed plans. The exact emergency procedure is
obviously dependent on the circumstances.
An example of this system in action is shown below. A potential
pathogen is released from a location within the mall and spreads
out in the mall through the duration of sixty minutes. As detectors
detect a pathogen, their color turns blue to show that the pathogen
has been detected.
Pathogen detectors would be attached to the central units where
potentially contaminated air enters the mall though ducts and also
through each mini unit in case contaminants are placed in the vicinity
of these. Since air circulates more rapidly near these blowers,
the hazard would spread more quickly -- another potential site for
effective terrorist offensives. Placing detectors near the mini
units averts this possibility.
Once a pathogen has been detected, the contaminated portion of
the mall could be shut down so that no persons contaminated can
be led to a decontamination area, while the rest of the mall should
be evacuated. A mall security team might be the first to arrive
to the contaminated region. They should help calm the shoppers,
and take any precautions needed to help those in the contaminated
area. For example, gas masks could be handed out if the situation
demanded so. The closest paramedics and emergency response center
should be notified of the detection of a pathogen and will send
an emergency response team. The people in the contaminated sector
could then be asked to move towards a sort of "decontamination"
exit of the mall. If they are infected or have inhaled the pathogen,
they should be examined by the paramedics. If infected they could
take drugs such as Cipro, a drug which treats many bacterial pathogens,
including anthrax. As the people are evacuated and treated, the
CDC and/or FBI could arrive in order to investigate the site and
clean up the area. The mall should be closed until the area is completely
safe.
We expect the sales of our system increase dramatically within
a short period of time. The government is currently doing anything
it can to increase the security in public places, and products
such as our detection system will be in heavy demand. The growth
of malls throughout the United States has been dramatic, with Simon
Properties being the largest mall chain in the country with 252
properties. We feel that with the growing number of malls across
the United States, and restoration of consumer confidence in goods,
more and more people will be shopping in malls in the next few years.
Shopping malls are dependent
on high-level security to keep people shopping at malls. Their
owners realize that people now have online alternatives to shopping,
so they will be more prone to obtaining a high-level defense system.
Though the monetary cost may be high, malls will gladly shoulder
them as the benefits of such a system outweigh the costs.
Using existing technology, the price of installing an Athena Project
system in a single mall is rather high. Though the Autonomous Pathogen
Detection System is not yet commercially available, we estimate
its price to be around $15,000 a unit based on the costs of existing
technologies. With an estimated need of 80 units per mall, the costs
of APDS alone is $1.2 million. The cost
of the monitoring software system is estimated at $85,000. Additional
training costs for mall personnel are negligible as the skills needed
to operate the ANAA can be taught fairly quickly. Gas masks are
priced at $299 a unit, and Cipro costs $5 a dose.

A program such as nVIZn, developed by Illumitek
Inc. could handle data monitoring and analysis. The system
they have developed allows for real-time display and analysis of
data received from the sensors in a variety of graphical arrays.
Further, information received can be archived and analyze to determine
patterns and statistics, so as to better monitor and assess the
protected sites. Information may be delegated to client systems,
so that the monitored sites can access their own information.
The detection and display/analysis components would ideally be
linked by wireless communications, which would allow for data to
be sent out over a wide range of frequencies and over a long distance.
Precautions such as signal encryption make wireless communications
quite secure. Even if the signal were to be compromised, an "eavesdropper"
would not be able to decode the message. RSA
Security Inc. supplies a variety of wireless security systems,
featuring cryptography to protect the code and client "certificate"
authorization. Certification would prevent unauthorized data transfer
and interference.
In 1987, the German company Bayer developed the drug ciprofloxacin,
Cipro,
an antibiotic that is effective against a wide array of pathogens
but is the most commonly used drug against anthrax. It is a synthetic
bactericidal antibiotic that can inhibit bacterial nuclear DNA
synthesis, so bacteria will rapidly die. Cipro is orally administered
and has treated more than 250 million patients worldwide. Since
the attacks on September 11th, Cipro sales have skyrocketed. Sales
have continued to grow in the United States, and the U.S. State
Department wants all US embassies to have a 3-day supply of Cipro
on hand for all employees. Cipro had worldwide sales of $1.6 billion
last year, and has an average wholesale price of nearly $5 for a
500-milligram pill. The recommended dose for anthrax is two 500
mg pills per day for 60 days. We believe that Cipro could be our
principle drug to be used against a possible biological attack in
order to treat those infected. A large supply of this drug should
be stored on-site in order to quickly treat anyone who may be infected.
In addition to Cipro, another antibiotic, such as penicillin, should
also be selected to prevent resistive cell selection.
American
Gas Masks is a large producer of gas masks for civilians. Many
different companies widely produce gas masks, and this company is
just one possibility for our supplier of gas masks. The gas masks
they produce have an 18-hour filter in order to filter out the harmful
microbes that could be in the air. The sales
of gas masks to civilians have soared due to the concern of
a potential attack with biological weapons. We believe that gas
masks are an essential part of our system after a pathogen is detected.
People need to quickly have access to air they can breathe.
The main product of our system is the Autonomous Pathogen Detection
System, but this is fairly new product and the scientists are still
trying to improve their product and eventually commercialize it.
The Advanced Nucleic Acid Analyzer is also undergoing similar tests.
The scientists at the National Laboratory in Livermore, California,
where both products are being tested, are hoping to increase the
number of pathogens the device can detect in order to offer a better
detection system.

The American Society for Microbiology
is a professional society for microbiologists. The mission of the
American Society for Microbiology is to advance the microbiological
sciences and their applications for the common good. It tries to
accomplish this goal by publishing journals and books, convening
meetings, and conducting and supporting education, training and
public information programs to facilitate the application of new
microbiological knowledge that address scientific matters which
affect the public interest. The ASM also promotes the microbiological
sciences with actions that both preserve the heritage, tradition

achievement, and distinction among its practitioners. This society
aims to set an example of ethical and professional behavior for
all students and practitioners of microbiology. The ASM strives
to ensure that all of our programs, products and services are of
the highest possible quality provided at the lowest possible cost,
and serve our members and other constituencies well. This society
does not have any companies involved, but rather scientists who
seek to further scientific knowledge and applications. The ASM has
great economic importance because it promotes the education of new
scientists, providing an economic incentive for new students in
the area to study microbiology and its applications to environmental
safety.
Company Evaluation
In the new and secretive environment of the anti-bioterrorism marketplace,
it has been hard to contact a company willing to spend the time
evaluating our project. Our team has contacted Cepheid,
Matech, C*CHEM,
International Safety Instruments,
and Micronel Safety
without a response from any of them. However, we were lucky enough
to have Dr. Guy Patra, a research
scientist in the Institute of Molecular Biology and Medicine at
the University of Scranton, evaluate
our project for us from a research perspective. We thank him for
the time and effort he spent on this valuable evaluation; his evaluation
follows below. We have attempted to follow up on as much of the
advice Dr. Patra has given us as possible. Note that because we
have changed some of our content since Dr. Patra's evaluation, much
of it as per his advice, some of the quoted text may not be available
in the final versions of the project's components.
Dr. Guy Patra's Evaluation
The contaminated letters with spores of Anthrax after the September
11, 2001 tragic events bring to us the reality of bioterrorism.
Because of the nature of the anthrax disease, a rapid and accurate
diagnosis is a key factor to prevent the death of exposed persons.
The "Athena Project" described in details with figures
"A system involving devices to detect and protect the public
from anthrax in contained facilities."
Component 1: Rather than the term "biochemical",
I will suggest the utilization of the terms "Chemical and/or
Biological" weapon. Both the anthrax and the botulism bacteria
produce a toxin, which when the spores of these bacteria are spread
by aerosol...no ambiguity now.
See the article of Rocco Casagrande "Detecting
Anthrax", in Scientific American, March 2002, page 55.
Component 2: "Each site hosting an Athena system would
be equipped with monitoring devices, which detect pathogens by means
of nucleic acid or immunofluorescence analysis; "
At this point my feeling is the first alert needs to be a "cytometry"
alert rather than a "nucleic acid " analysis alert. According
to the text the Athena system is planning to do a reaction every
thirty seconds, this means 2880 PCR reactions per day. The cost
will be very high.
I will suggest as a first alert, a "Particle recognition"
system based on Cytometry measures.
See Davey H. M. et al. 2000. A portable flow cytometer for the
detection and identification of microorganisms in "Rapid methods
for analysis of biological materials in the environment" NATO
ASI Series. Vol. 30. p. 159-167 Ed. P. J. Stopa and M. A. Bartoszcze.
And Winson M. K. and Davey H. M. 2000, Flow cytometric analysis
of microorganisms. Methods 21(3): 231-241.
Regarding the Advanced Nucleic Acid Analyzer (ANAA): in fact the
DNA is not directly accessible from the anthrax spore. The spore
coat protects the inside spore environment very well from the outside.
Also, for example a PCR is not possible directly from spores because
the DNA is not accessible. However it is possible from vegetative
cells. Also if the spore preparation contains some vegetative cells,
it is OK to do PCR or other nucleic acid tests. In fact there are
methods to extract DNA from spores, which can be automated in the
future.
For the antibiotic treatment, I will recommend Ciprofloxacine plus
another antibiotic to prevent any resistance cell selection, because
the actual treatment recommended is 60 days. Penicillin and Doxycycline
are good candidates. Anthrax from the environment is very sensitive
to broad range of antibiotics. Some Penicillin resistant strains
are described in the literature.
In any case, it is important to keep a sample of the anthrax spores
during an attack for further epidemiological study (fingerprinting
investigation). This is the way to trace the origin of the contamination
and find the people responsible for the attack.
Component 3: This part emphasizes the fact that the Athena
system is fully automated (computer-operated). Also points to the
fact that America is facing Bioterrorism and that the society has
to adapt rapidly to the new kind of attacks. This can take place
with the Biological Terrorism Prevention (BTP) action.
General remarks: The project is well written, clear and
with selected figures to support the text. The name of Athena for
the project is very a good choice from the Greek mythology. The
bibliography is well documented. The actual project is under development
and evaluation, and all components are in place to build a prototype
in the near future.
