Anthrax is the preferred biological warfare agent because:
It is highly lethal.
100 million lethal doses per gram of anthrax material (100,000 times deadlier than the deadliest chemical warfare agent).
Silent, invisible killer.
Inhalational anthrax is virtually always fatal.
There are low barriers to production.
Low cost of producing the anthrax material.
Not high-technology. Knowledge is widely available.
Easy to produce in large quantities.
It is easy to weaponize.
It is extremely stable. It can be stored almost indefinitely as a dry powder.
It can be loaded, in a freeze-dried condition, in munitions or disseminated as an aerosol with crude sprayers.
Currently, we have a limited detection capability.
What is Anthrax?
Anthrax is a naturally occurring disease of plant eating animals (goats, sheep, cattle, wine, etc.) caused by the bacterium Bacillus anthracis.
It is an illness which has been recognized since antiquity. Anthrax was common in essentially all areas where livestock are raised. Intensive livestock immunization programs have greatly reduced the occurrence of the disease among both animals and humans in much of the world, an most outbreaks occur in areas where immunization programs have not been implemented or have become compromised (primarily Africa and Asia; however, outbreaks occurred during the mid- I 990's in Haiti and the former Soviet Union).
Anthrax spores can remain viable for several decades under suitable environmental conditions; thus, absence of cases does not equate to absence of risk.
Humans can contract anthrax in three ways:
Through cuts or breaks in the skin resulting from contact with an infected animal (cutaneous anthrax), resulting in local and possibly systemic (bloodstream) infection.
From breathing anthrax spores (termed "woolsorters" disease) resulting in an infection of the lungs (inhalational anthrax).
From eating infected meat, resulting in gastrointestinal infection (gastrointestinal anthrax). Gastrointestinal anthrax is generally not considered a threat to U.S. forces.
What are the symptoms?
Symptoms of anthrax begin after a 1 to 6 day incubation period following exposure.
For contact or cutaneous anthrax, itching will occur at the site of exposure followed by the formation of a lesion. Untreated contact anthrax has a fatality rate of 5-20 percent, but with effective antibiotic treatment, few deaths occur.
Initial symptoms for inhalational anthrax are generally non-specific: low grade fever, a dry hacking cough, and weakness. The person may briefly improve after 2 to 4 days; however within 24 hours after this brief improvement, respiratory distress occurs with shock and death following shortly thereafter.
The case, Near v Minnesota, took place in Minneapolis in 1929. It was argued on January 30, 1931 and was decided on June 1, 1931. This case appeared in the supreme court after the constitutionality of Minnesota’s law was questioned by Jay Near, the defendant. Near was to be censored due to his "malicious, scandalous and defamatory" article about the Chicago chief of police and many other local officials with being affiliated with gangsters. This then led to a lawsuit that formed from an attempt by Floyd B. Olson, to shut down the local newspaper owned by Jay Near that used racial language in its criticism of local officials and political figures. Olson claimed the paper violated the state’s nuisance law, and both the county court and Minnesota Supreme Court upheld Olson’s right to shut down the paper under Minnesota’s nuisance law. This was questioned because it was unclear whether or not the law permitted by the state would be impeding upon the defendant 's freedom of speech and even freedom of press.
After an incubation period of five to ten days, or as long as 21 days, numerous symptoms can be observed. The symptoms come in two stages. The first stage consists of common cold symptoms such as sneezing, runny nose, low-grade fever, and a mild cough. It is during this time that the disease is most contagious, and it lasts from one to two weeks.
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...
The main objectives of the pathogen are to gain entry inside the host, once inside grow and reproduce, and avoid host defenses. There are three possible routes of infection: respiratory, alimentary, and traumatic. The respiratory route is the easiest and most direct means of entry. Under crowded conditions, the rate of infection is even more rapid. The diseases brought over to America were mainly spread by the respiratory method. The alimentary pathway of infection is through the ingestion of contaminated food and water. Throughout Europe during the 15th century, food and water were contaminated with fecal matter and by unsanitary habits ( i.e. the lack of bathing). The traumatic route of infection is through insect and animal bites.
When one thinks of great powerful empires and nations of any time, they would think of Ancient Rome. So how would future nations take what the almighty Roman empire had to build their own successful country? After all, the Romans did eventually fall. This means that nations would have to mimic but not copy their exact steps and acts. It is an ultimate mystery of picking and choosing. However, many of the things Rome did were very important. In the United States of America, we see some direct connections from Ancient Rome. These connections have to do with anything from politics, social living, geography, government, sport, and many more. All in all, America would not be the same if it were not for Roman connections.
the animals and cattle as well. The disease was so contagious that touching even an object that had
It was spread very slowly and less broadly than other viral illnesses which took a long time to identify the infection in the first two weeks. Infection of smallpox started to grow between 7 to 10 days when the scabs formed into bruises. The signs and symptoms of this disease include high fever, widespread rashes, redness, muscle pain, headache, common cold, vomiting, nausea and many more. Consequently, the virus was found in the bone marrow along with bloodstream in huge numbers. There are different types of the smallpox disease with other classifications.
Although the Columbian Exchange allowed for the beneficial exchange of cultures, ideas, foods, and animals around the world during the 1450-1750 time period, it also had a dark side. One detrimental result of the Columbian Exchange would be the spreading of smallpox from Europe to the New World.
Masks and personal protective equipment were not worn by the factory workers. With no preventative measures taken, workers respiratory tracts were exposed to cotton, flax, and hemp dust. This exposer caused side effects such as chest tightness, shortness of breath, long term respiratory diseases (COPD), and permeant loss of lung functions. These symptoms were later classified as a syndrome called byssinosis before disease were diagnoses. According to the online article, “Long term respiratory health effects in textile workers,” there were two obstructive lung diseases textile workers exhibited, Asthma and COPD. The article states that two hundred and twenty-five newly hired textile workers were studies and found to have increased in asthma like symptoms at a one year follow up. The article continues to explain that there was an increase in incidence of chronic and progressive dyspnea, cough, and sputum production characteristic of COPD seen textile workers on year follow up as well. Another lung problem seen in some textile workers per Dr. Edward Holmes interview in 1818 was Scrofula, known today as
“African Americans have just as amount of chance of becoming a professional athlete as he or she winning the lottery”. This so called goal of theirs is unrealistic and is highly impossible. There are so many sports athletes but majority of them are of a different c...
“While stands the Coliseum, Rome shall stand; When falls the Coliseum, Rome shall fall; And when Rome falls - the World.” Lord Byron. This essay will discuss the similarities of military, economics and systems of government between the Roman Empire of the 6th century BCE and the United States of America of the 20th century. History has revealed that all superpowers fall eventually, although much time has passed since the glory days of Rome we see in 2015 the largest superpower in charge, the United States. There are many similarities that can be drawn between the American superpower and the Roman Empire such as the same founding of government and both dominated in military, as well as economic similarities. This leads to the conclusion that because the rise to power between the two powers was so similar, the downfall will be equally parallel.
Wear gloves and proper cloths if handling the infected animals to prevent the direct contact.
Bacterial cells, like plant cells, are surrounded by a cell wall. However, bacterial cell walls are made up of polysaccharide chains linked to amino acids, while plant cell walls are made up of cellulose, which contains no amino acids. Many bacteria secrete a slimy capsule around the outside of the cell wall. The capsule provides additional protection for the cell. Many of the bacteria that cause diseases in animals are surrounded by a capsule. The capsule prevents the white blood cells and antibodies from destroying the invading bacterium. Inside the capsule and the cell wall is the cell membrane. In aerobic bacteria, the reactions of cellular respiration take place on fingerlike infoldings of the cell membrane. Ribosomes are scattered throughout the cytoplasm, and the DNA is generally found in the center of the cell. Many bacilli and spirilla have flagella, which are used for locomotion in water. A few types of bacteria that lack flagella move by gliding on a surface. However, the mechanism of this gliding motion is unknown. Most bacteria are aerobic, they require free oxygen to carry on cellular respiration. Some bacteria, called facultatibe anaerobes can live in either the presence or absence of free oxygen. They obtain energy either by aerobic respiration when oxygen is present or by fermentation when oxygen is absent. Still other bacteria cannot live in the presence of oxygen. These are called obligate anaerobes. Such bacteria obtain energy only fermentation. Through fermentation, different groups of bacteria produce a wide variety of organic compounds. Besides ethyl alcohol and lactic acid, bacterial fermentation can produce acetic acid, acetone, butyl alcohol, glycol, butyric acid, propionic acid, and methane, the main component of natural gas. Most bacteria are heterotrophic bacteria are either saprophytes or parasites. Saprophytes feed on the remains of dead plants and animals, and ordinarily do not cause disease. They release digestive enzymes onto the organic matter. The enzymes breakdown the large food molecules into smaller molecules, which are absorbed by the bacterial cells. Parasites live on or in living organisms, and may cause disease. A few types of bacteria are Autotrophic, they can synthesize the organic nutrients they require from inorganic substances. Autotrophic bacteria are either photosynthetic or Chemosynthetic. The photosynthetic bacteria contain chlorophyll that are different from the plant chlorophyll. In bacterial photosynthesis, hydrogen is obtained by the splitting of compounds other than water.
It all started because Great Britain was afraid that Germany and Japan had a great advantage in biological technology in comparison to them. They were testing to see the range of spread of the anthrax spores. Great Britain tested its weapons on the coast of the Island of Gruinard in Scotland were they thought it was far enough from they coast so it would not contaminate or hurt the mainland. In the year of 1943 throughout many experiments that were conducted it was proven that sheep and cattle were affected with anthrax. The British government thought of decontaminating the island that that meant that they had to brushfire they entire island to kill all of th...
What types of crime are considered to be the most costly to a country? Could it be street crime? Vandalism, breaking and entering, carjacking and pick pocketing are all examples of street crime, “a crime committed by average people against other people or organizations, usually in public spaces” (Open Education Sociology Dictionary). Street crime usually involves material possessions of large monetary amounts, costing the global economy an estimated $16.6 billion (Simon) so perhaps this could this be the most expensive type of crime. However, according to the 2014 Report to the Nations on Occupational Fraud and Abuse, corporate crime and fraud costs the global economy more than $3.7 trillion (ACFE). Investopedia defines corporate fraud, or
