Anthrax is a serious infectious illness caused by the microbe Bacillus anthracis. This microbe resides in soil. Anthrax became widely known in 2001 when it was used as a biological weapon. Powdered anthrax spores were sent via letters in U.S. mail.

Can deer eat anthrax?
Wild animals like deer, and livestock such as cattle or sheep, can inhale or ingest the dormant (inactive) spores while grazing. After mixing with bodily fluids, anthrax bacteria activate, multiply and spread throughout the body. The bacteria cause a toxic, potentially deadly reaction.

7.1.1. Background
In a review of treatment in the early days of antibiotics half a century ago, Herman Gold (1955) wrote: “penicillin and the broad spectrum antibiotics … have simplified the management of anthrax so that one can safely say that, in man, this disease has lost its serious connotations”.
7.1.3. Supportive care
In pulmonary or gastrointestinal anthrax or cutaneous disease with systemic signs, symptomatic treatment in an intensive care unit in addition to antibiotic therapy may save the patient’s life.
7.1.4. Vaccines
Anthrax in its natural state being primarily a disease of herbivorous animals ( section 1.1 ), its control in both animals and humans depends to a very great extent on its prevention in livestock (principally cattle, sheep, goats and horses), good hygienic practices when an animal dies of anthrax and antibiotic treatment when a case occurs, at least in a human.
7.2.1. General principles and approaches
Following the first incident of anthrax in a herd, the remaining animals should be moved immediately from the field or area where the index case died, and regularly checked at least three times a day for two weeks for signs of illness (rapid breathing, elevated body temperature), or of submandibular or other oedema.
7.2.2. Specific procedures
The recommended procedure for treating animals showing clinical illness in which anthrax is thought to be the likely or possible cause is immediate intravenous administration of sodium benzylpenicillin as directed by the manufacturer’s instructions (usually in the range 12 000–22 000 units per kg of body weight) followed 6–8 hours later by intramuscular injection of long-acting benethamine penicillin (manufacturers’ instructions usually recommend a dose within the range of 6000–12 000 units per kg of body weight) or other appropriate preparation such as Clamoxyl® (15 mg/kg), a long–acting preparation of amoxycillin.
7.3.1. Developing countries, naturally acquired anthrax
Penicillin G is still the drug of choice in the therapy of naturally-occurring anthrax in most parts of the world.
7.3.2. Treatment in high-economy (developed) countries
Fear resulting from increasing numbers of anthrax hoaxes, especially in the USA, and then the 2001 anthrax letter events, also in the USA, have led to recommended treatment schedules that would frequently not be possible in developing countries.
What is the best treatment for anthrax?
Treatment for anthrax infection and other bacterial infections includes large doses of intravenous and oral antibiotics, such as fluoroquinolones ( ciprofloxacin ), doxycycline, erythromycin, vancomycin, or penicillin. FDA-approved agents include ciprofloxacin, doxycycline, and penicillin.
What are the preventive measures for anthrax?
Preventive antibiotics are recommended in those who have been exposed. Early detection of sources of anthrax infection can allow preventive measures to be taken. In response to the anthrax attacks of October 2001, the United States Postal Service (USPS) installed biodetection systems (BDSs) in their large-scale mail processing facilities. BDS response plans were formulated by the USPS in conjunction with local responders including fire, police, hospitals, and public health. Employees of these facilities have been educated about anthrax, response actions, and prophylactic medication. Because of the time delay inherent in getting final verification that anthrax has been used, prophylactic antibiotic treatment of possibly exposed personnel must be started as soon as possible.
How long does it take for anthrax to show up?
It can occur in four forms: skin, lungs, intestinal and injection. Symptom onset occurs between one day to over two months after the infection is contracted.
What is the most common form of anthrax?
Cutaneous anthrax, also known as hide-porter's disease, is when anthrax occurs on the skin. It is the most common form (>90% of anthrax cases). It is the least dangerous form (low mortality with treatment, 23.7% mortality without). Cutaneous anthrax presents as a boil -like skin lesion that eventually forms an ulcer with a black center ( eschar ). The black eschar often shows up as a large, painless, necrotic ulcer (beginning as an irritating and itchy skin lesion or blister that is dark and usually concentrated as a black dot, somewhat resembling bread mold) at the site of infection. In general, cutaneous infections form within the site of spore penetration between two and five days after exposure. Unlike bruises or most other lesions, cutaneous anthrax infections normally do not cause pain. Nearby lymph nodes may become infected, reddened, swollen, and painful. A scab forms over the lesion soon, and falls off in a few weeks. Complete recovery may take longer. Cutaneous anthrax is typically caused when B. anthracis spores enter through cuts on the skin. This form is found most commonly when humans handle infected animals and/or animal products.
When was the last time anthrax was inhaled?
The last fatal case of natural inhalational anthrax in the United States occurred in California in 1976, when a home weaver died after working with infected wool imported from Pakistan. To minimize the chance of spreading the disease, the body was transported to UCLA in a sealed plastic body bag within a sealed metal container for autopsy.
What is the intestinal form of anthrax?
The intestinal form presents with diarrhea which may contain blood, abdominal pains, nausea, and vomiting. The injection form presents with fever and an abscess at the site of drug injection. Anthrax is spread by contact with the bacterium's spores, which often appear in infectious animal products.
Where are anthrax spores picked up?
The spores are then picked up by scavenger cells ( macrophages) in the lungs and are transported through small vessels ( lymphatics) to the lymph nodes in the central chest cavity ( mediastinum ). Damage caused by the anthrax spores and bacilli to the central chest cavity can cause chest pain and difficulty breathing.
