Anthrax is an acute infection that usually affects the skin, lungs, and the digestive tract.
This disease is caused by the spore- forming, rod- shaped bacterium known as Bacillus anthracis. The gram positive spores of Bacillus anthracis are usually spread to humans from livestock, especially from goats, cows, and sheep. This type of infection can not spread from person to person. The dormant spores of Bacillus anthracis can live in soil and animal products, such as leather, for many years and is not easily killed by heat or cold. Once these spores are eaten by the livestock, they are quickly activated and the bacteria reproduce. The exposed animal usually dies, and the bacteria is returned to the soil and water as spores, creating an on going cycle. Although humans are more susceptible to this infection through the skin (cutaneous), it can also result from inhalation, or from eating contaminated meat.
The most common form of infection is known as cutaneous anthrax and results in about ninety five percent of all cases. Cutaneous anthrax usually occurs when bacteria from infected animal products, such as carcasses or wool, enter a break in the skin. This skin infection begins as a painless red bump similar to that of an insect bite. After about one to five days, the bump forms a blister that eventually breaks open to form a eschar (a black scab). Lymph nodes in the infected area may swell and the person may experience fever, nausea, muscle aches, headaches, and vomiting. Death from cutaneous anthrax is rare with the appropriate antimicrobial therapy. One out of five people who contract cutaneous anthrax and are left untreated will die.
Gastrointestinal tract anthrax, or anthrax of the digestive tract is not very common and has not been known to have occurred in the United States. When a person eats contaminated meat, the bacterium Bacillus anthracis begins to grow in the throat, mouth, or intestines. The bacteria releases...
