Anthrax is an infection caused by the bacteria bacillus anthracis. It has different presentations and primarily attacks cattle and herbivores, but it is also contageous to man.

In the 18th and 19th centuries anthrax in its epidemic form was not too rarely seen on the European continent. It was not until 1849 that the German bacteriologist Robert Koch demonstrated that the epidemiological origin of anthrax was bacterial.
Later on, Louis Pasteur was able to produce the effective vaccine.

Cases of anthrax are still seen in Southern and Central America, Southern and Eastern Europe, in Africa, Asia, and in the Middle East, primarily in agricultural areas and areas where livestock is present.

Human disease commonly results from exposure to contaminated animals or animal byproducts. There have even been reports of humans catching the disease by using shaving brushes made from horsehair, or by having contact with leather or other materials from contaminated animals. Cases of human infection through direct or indirect contact with contaminated individuals are extremely rare.

The anthrax bacterion (baccillus anthracis) is a non-moveable gram-positive bacillus. Being a facultative anaerobic bacterion it has the ability to live in normal oxygen concentrations as well as in the absence of oxygen. The optimal temperature for bacterial growth is around 35 degrees Cp. Increasing temerature to 42 - 43 degrees C will result in considerable bacterial weakening because of the loss of its surrounding polypeptide capsule. Outside the body anthrax bacteria have the ability to dry up into an extremely resistant spore, witch can survive for many years in nature. Spores form in the soil and can be carried away with the wind, travelling long distances. Spores usually have to be burned, or destroyed through autoclaving, an effective form of disinfection where the material is heated to 120 degrees C using steam pressure.

There are three presentations of anthrax known to infect humans.

  • Cutaneous anthrax, malignant postule form is most common. Bacterial spores enter the body through scratches in the skin and create an elevated cutaneous wound or papule that enlarges and erodes into an ulcer. Nearby lymph nodes may be swollen. As the disease progresses, ulcerations gradually darken to purple or black, and a charcoal carbuncle is formed (anthrax meas charcoal in Greek). Typical attending symptoms are headaches, fever, and vomiting.
  • Gastro-intestinal anthrax. This form is aquired by eating or drinking contaminated material, most often meat. Symptoms are loss of appetite, nausea, and vomiting, developing into stomach ache, severe diarrhoea, and vomiting blood.
  • Pulmonary anthrax, wool-sorters disease, develops when spores of B. Anthracis are inhaled, and the disease progresses through the airways. Large quantities of bacteria are found in saliva. This is by far the most dangerous form of infection. The disease presents symptoms resembling a cold or the flu which after a few days develops into worsening respiratory distress or respiratory failure.

The spores of B anthracis germinate in the body to yield vegetative bacteria which multiply and release a potent necrotizing toxin. Bacterial toxins severely impair the natural defence of the immune system and its ability to fight infection. Bacteria are able to withstand attack from white blood cells. The spleen that produces the white blood cells will swell and if left untreated the patient may die of blood poisoning as anthrax toxin levels rise dramatically in the later stages of disease development.
The incubation period can vary from 2 to 6 days depending on pathology.
Untreated, mortality varies from 20% in cutaneous anthrax to 90% in pulmonary anthrax.
Anthrax spores is one of the micro-organism used in biological weapons. The effectiveness of anthrax in biological warfare is the result of a relatively high mortality compared to other bacterial infections in combination with the high durability of bacterial spores. In addition, spores are relatively easy to mount in different weapon systems making it possible to spread spores over large areas.

Anthrax spores are hardly visible and has neather smell nor taste. The presence of visible powder is therefore not an indication of anthrax spores.


When travelling to countries where outbreaks of anthrax are common in livestock one should avoid contact with contaminated animals or animal byproducts.

Anthrax can be treated with antibiotics and when treatment is initiated within 36 hours of the first contact with bacterial material, one is likely to achieve complete recovery. A more dangerous situation arises if treatment is not initiated until symptoms have developed.

In order to prevent bacterial infection a vaccine has been developed. The vaccine is injected into the subcutis following a vaccination program where a number of monthly injections are followed by one injection given 12 months after the last vaccination. Anthrax vaccine programs are not common in European countries, although military personnel who are likely to encounter infection in the field are given the vaccine. The vaccine may have several side effects.

The use of gas masks is generally not likely to offer sufficient protection against anthrax spores. However, anthrax spores on the skin can be washed off with water and soap. The spores will especially be located on the areas of the skin where there is hair growth.

Contrary to general belief, several natural remedies may be used in the treatment of anthrax infection and are not without therapeutical value. Especially if no other treatment is available. These include:

  • Garlic. Should be administered in concentrated form, as either capsules, powder, or another type of extract.
  • Black tea: Common black teat contains polyphenols, which have the ability to counteract the anthrax bacteria. The tea must be taken without milk to achieve this effect.
  • Vitamin C. Bacterial infection has been shown to degrade large quantities of vitamin C. Therefore, large doses of vitamin C can be administered without risks of usual gastro-intestinal side effects such as diarrhoea. A vitamin supplement can be given together with antibiotics without complications. In fact, antibiotic side effects may be diminished as a result of administration of vitamin C. Tissue-damage caused by the action of anthrax toxins may be counteracted. Treatment of the severe pulmonary infection is likely to require administration of intravenous injections in doses up to 200 g. of sodium ascorbate. When given as capsules, calcium ascorbate is used until diarrhoea develops.
  • Gluthatione - Counteracts the inflammation caused by infectious agents.
  • Lipoic acid. A powerfull antioxidizer. Capable of reducing neural damage caused by toxic agents.
  • N-acetyl cysteine. Known for its detoxifying abilities.
  • Taurine. Possibly because body levels may fall dramatically during intoxication.
  • Melatonin. Material is available that indicates that supplements may counteract the effects of anthrax toxins. 5 mg. before bedtime for mild conditions. 20 mg. in more severe cases.


In case of anthrax infection one should consult a physisian before initiating self treatment.
