In 1877, Robert koch grew an organism called anthrax. He tested, demonstrated, and produced anthrax by injecting it into animals. Anthrax is an animal disease that can be transmitted to humans by direct contact with infected animals or their products. The spore-forming bacteria called Bacillus Anthracis cause it.
             Anthrax occurs mostly in cattle, sheep, goats, camels, antelopes, and other herbivores, but it can also occur in humans, if they are exposed to an infected animal.
             Anthrax is one of the easiest biological agents to manufacture, it is easy to develop as a weapon, easily spread in the air over a large area, also is easily stored and dangerous for a long time.
             1) Cutaneous Anthrax: most common form of the disease in humans; caused by contact with the infected animals. It is usually an exposed area of skin. About 20% of untreated cases will result in death.
             2) Gastrointestinal Anthrax: ingestion of contaminated meat. Food poisoning occurs when spores survive cooking or pasteurization and multiply when the food poorly refrigerated.
             3) Inhalation Anthrax: inhalation of anthrax spores. It is the most deadly kind of anthrax, because the spores are inhaled and stuck in the lungs, where they travel to the lymph nodes, change to bacteria form, multiply and produce toxins. The toxins are then spread throughout the body, through the bloodstream, leading to shock and death within 24-48 hours.
             Some of the symptoms of cutaneous anthrax are a raised itchy bump that looks kind of like a insect bite but within 1-2 days develops into a serum-filled blister, then a painless ulcer, usually 1-3 cm in diamerter, with black necrotic area in the center. The symptoms for gastrointestinal anthrax are nausea, loss of apetite, vomiting, fever are followed by pain, vomiting of blood, and diarrhea. Gastrointestinal anthrax results in death in 25% to 60% of cases. Inhalation symptoms resemble the common cold. Afte
