THE BIGGEST WAR in the Worlds history is waiting to strike. Anthrax is considered as the deadliest bioweapon known to mankind (Discovery News, 2012) . Anthrax is a silent killer; symptoms of flu layer the biological weapon. The first epidemic known as “Black Bane” was recorded in 1613, where the plague swept through Europe causing more than 60,000 recorded deaths (Siumed.edu, 2010). In recent cases, the silent killer, re-appeared in 2001, where air mail from Russia swept through a postal service in the US, affecting 66 people and killing seven. The term Anthrax is a derivative of the scientific name Bacillus Anthracis; a gram positive rod shaped, facultative anaerobic bacterium, ranging from seven to nine micrometers in diameter …show more content…
Common hosts include wild and domestic livestock for instance goats, cattle, horses and sheep (Mayoclinic.org, 2012). Unlike other pathogenic bacteria, which are host specific; only to be able to affect one specific species, Anthrax is able to infect livestock and humans, with soil having little to no effect until it is transferred to a host. Although the silent killer is most commonly found in developing countries, it is also found in agricultural environments like Central and South America, Central and Southwestern Asia, Southern and Eastern Europe and also the Caribbean (Cdc.gov, 2013). Anthrax is rare in first world countries like Australia and the United States, but erratic outbreaks do occur. A SILENT KILLER
The silent killer, Anthrax, has been recognised as a highly likely biological or terrorist agent (KIEL et al., 2000). It is an acute bacterial disease which usually affects the skin, providing indicators of regular infections like flu, causing one to have various symptoms such as itching, fever, cough, headache, and swelling of abdomen. These are very typical symptoms animals and humans overcome on a regular

These enzymes are responsible for the transmission of cell signaling within the cell itself. The enzyme controls growth and embryonic development and by eliminating or disturbing the transmission, it causes a cell to malfunction and denature, creating larger more dangerous concern.
CONTROLLING A PREDATOR
The 7 billion people around the world have a lot to lose, if at any stage an outbreak of Anthrax triumphed. Effects of an outbreak may be catastrophic, the slightest presence of Anthrax needs to be responded to instantaneously with vast importance and control. For these reasons, increased biosecurity has been instigated in every tier of society (Dance, 2008). Control steps are rigorously implemented, measures like correct disposal of Anthrax carcasses, correct disinfection, decontamination and disposal of contaminated materials and also vaccinating any exposed animals and humans at risk, are all measures strongly practiced.

This summer we had an opportunity to dive into the world of bioweapons, through Richard Preston’s novel The Demon in the Freezer. His book explored the colorful world of smallpox and its use as a biological weapon. Earlier this week we were graced with this authors present for an ACES event. He discussed some of the found topics in his book such as animal testing, what small pox is, and even its eradication. One of the great things we had the chance of vocalizing were our many opinions on the gloom associated with this intriguing disease.
The Demon in the Freezer by Richard Preston is an intriguing book that discusses the anthrax terrorist attacks after 9/11 and how smallpox might become a future bioterrorist threat to the world. The book provides a brief history of the smallpox disease including details of an outbreak in Germany in 1970. The disease was eradicated in 1979 due to the World Health Organization’s aggressive vaccine program. After the virus was no longer a treat the World Health Organization discontinued recommending the smallpox vaccination. In conjunction, inventory of the vaccine was decreased to save money. The virus was locked up in two labs, one in the United States and one in Russia. However, some feel the smallpox virus exists elsewhere. Dr. Peter Jahrling and a team of scientists at the U.S. Army Medical Research Institute of Infectious Diseases in Maryland became concerned terrorists had access to the smallpox virus and planed to alter the strain to become more resistant. These doctors conducted smallpox experiments to discover more effective vaccines in case the virus were released. Preparedness for a major epidemic is discussed as well as the ease with which smallpox can be bioengineered.

Anthrax is one of the most preferred biological warfare agents for many highly identified reasons. First, anthrax is extremely lethal. Anthrax can contain up to 100 million lethal doses in just one gram of anthrax spores, which is 100,000 times more lethal than any other biological warfare agent. It is also known that inhalation anthrax is almost always fatal if the symptoms are allowed to progress without any treatment. Anthrax is also the silent and invisible killer. On top of the fatality rate of anthrax, there are also very low barriers to produce the biological weapon. Anthrax spores are very easy to produce in large quantities, and the process of production is very inexpensive. Also, there is plenty of available information on how to weaponize anthrax and not a whole lot of technology is needed to be able to produce anthrax. Anthrax is also easy to weaponize because it is extremely stable as a dry powder in the form of spores. These spores can live for decades and still be very lethal to the human body. Anthrax can be put into an aerosol form disseminated into a spray can, and it can also be freeze-dried into a bomb. Presently anthrax is the most preferred biological agent is because we have no accurate detection capability.
The 2001 anthrax attacks was one of the worst bio-weapon attacks on the US in history. The attacks where done through the mail. The anthrax was placed in envelopes with a letter and mailed from various locations to different people and organizations. The anthrax filled letters ended up killing 5 people, causing 17 to become sick and exposing anthrax it is believed to as many as 30,000 people. During the mail process spores of anthrax from the letters escaped and got on mailroom equipment exposing postal employees. If a person was exposed to enough anthrax and developed symptoms they typically died in a few days. Postal workers during the attacks where told that anthrax will appear as a white powder t...

On September 18th and the weeks following, a multitude of letters containing the Bacillus Anthracis bacterium were mailed to various New York news stations. Individuals at 5 different stations became ill with similar symptoms that included vomiting and shortness of breath. This began the nationwide panic known as the Amerithrax Investigation. The Amerithrax investigation was said to be the worst biological attacks in all of US History. Three weeks later, on October 9th, two more letters, containing the anthrax bacterium was mailed to two Democratic senators. In all of the 7 attacks, over 22 people developed infections, over half being life-threatening. The letters themselves confused federal investigators. In the sets of letters addressed to the media, certain T’s and A’s were bolded. When added together, the groups of letters formed 3 codons that corresponded to 3 amino acids. These amino acids pointed federal investigators towards a possible culprit, Bruce Edwards Ivins, a scientist for the US government in Frederick, Maryland.
From 166 A.D. to 180 A.D., The Antonine Plague spread around Europe devastating many countries. This epidemic killed thousands per day and is also known as the modern-day name Smallpox. It is known as one of deadliest plagues around the world.

Bacillus anthracis or anthrax is bacteria that infect thousands of people a year worldwide. Mostly found in the hinds and hair of grazing animals like cattle and sheep, the bacteria can stay dormant for years until contacted. Contact can occur through broken skin, eating infected meat, or inhaling infected dust from hides through the mouth or nostrils. Normal contact through the skin begins forming malignant skin ulcers that are dark black in appearance. If left untreated, the blisters lead to blood poisoning and eventually death. Eating contaminated meat not fully cooked can cause intestinal infection also leading to death. Surprisingly, many people survive contact of the skin and very few cases of intestinal infection exist. However, inhalation of infected dust or spores are much more deadly because the symptoms resemble a common cold...
Louis Pasteur, in 1881, discovered the anthrax vaccine. Anthrax is an infection caused by many bacteria cells called “Bacillus”. These bacteria make “spores” which have a protective shell. This disease is most common in farm animals. They live in soil, and affect domestic a...
Anthrax is a very real and dangerous threat to all people who come in contact with it. The bacterial infection is caused by the bacteriaium Bacillus anthracis. Anthrax is divided into three categories all are contracted in different ways. The first type is called Cutaneous Anthrax; this is where anthrax spores make contact with the skin. If there is a cut or a lesion then a person can be infected. Cutaneous Anthrax is the most common way to get anthrax, but is also the least lethal. The second type of anthrax is called Pulmonary Anthrax this is where a person inhales the spores of anthrax directly into the lungs. If this type of anthrax is left untreated it could lead to death. The third type of anthrax is called Gastrointestinal Anthrax, this form results from eating meat from animals that have been infected with the anthrax bacteria. This causes the intestinal tract to become infected and this from is almost always fatal. This particular mode of anthrax has never been seen in the United States.
Department of State, the perception of people on biosecurity threat has evolved as they “see the world in terms of a multipolar, multi-threat environment”. It further stated that “biorisk and matrices to measure the weighted value of each risk have become the norm, and biosecurity and biosafety have come to encompass the use of proper safety measures and facility specifications, as well as the proper training of employees to ensure not only their own safety but that of the public at large.”
Chicken pox is not an Entrée that is served at one’s family holiday dinner party. Chicken pox is an extremely contagious disease caused by the Varicella zoster virus. Chicken Pox is not a disease that is known to affect other animals or insects. Unlike other diseases, where human and other animal close interaction causes the exchange of virus and disease this disease did not come from a human-chicken interaction. The name chicken pox has been stuck for generations; there are many theories behind its name. Chicken pox could sneak up on its young victims in the form of an innocent touch, or by inhaling tiny particles from a cough, or sneeze which then enters the respiratory tract. Once the virus attaches itself to it gracious, and unwilling host cells it causes a crimson rash that could be located on different parts of the body. The rash is highly irritating which makes it almost impossible not scratch. In the United States each year about 5,000 to 9,000 people are hospitalized, and around 100 people die from the microbe Varicella zoster that causes chicken pox.
