Anthrax facts

  • Anthrax is an infection by bacteria, Bacillus anthracis, usually transmitted from animals.
  • Anthrax causes skin, lung, and bowel disease and can be deadly.
  • Anthrax is diagnosed using bacterial cultures from infected tissues.
  • There are four types of anthrax: cutaneous, inhalation, gastrointestinal, and injection.
  • Anthrax is treated by antibiotics.
  • Pulmonary anthrax is often lethal.
  • It is possible to prevent anthrax.
  • Sadly, the greatest threat of anthrax today is through a bioterrorist attack.
  • Federal, state, and local agencies are working hard to deal with this bioterrorist threat.

What is anthrax? Is anthrax contagious?

Anthrax is a life-threatening infectious disease caused by Bacillus anthracis that normally affects animals, especially ruminants (such as goats, cattle, sheep, and horses). Anthrax can be transmitted to humans by contact with infected animals or their products. In recent years, anthrax has received a great deal of attention as it has become clear that the infection can also be spread by a bioterrorist attack or by biological warfare. Anthrax does not spread from person to person and is not considered contagious.

There have been a number of outbreaks over the years that are usually localized. Most recently in 2016, in Siberia, Russia, there was a major outbreak of anthrax that sickened at least 13 Siberian people and killed over 2,000 reindeer. Authorities believe that the melting permafrost unburied a reindeer that died of anthrax 75 years ago, causing the release of anthrax spores.

What causes anthrax?

The agent of anthrax is a bacterium called Bacillus anthracis. While other investigators discovered the anthrax bacillus, it was a German physician and scientist, Dr. Robert Koch, who proved that the anthrax bacterium was the cause of a disease that affected farm animals in his community. Under the microscope, the bacteria look like large rods. However, in the soil, where they live, anthrax organisms exist in a dormant form called spores. These spores are very hardy and difficult to destroy. The spores have been known to survive in the soil for as long as 48 years. The bacteria secrete toxins composed of three proteins termed protective antigen, lethal factor, and edema factor.
