What does Bacillus anthracis cause?

Anthrax is a rare infectious disease caused by the bacterium Bacillus anthracis. Anthrax occurs naturally around the world in wild and domestic hoofed animals, especially cattle, sheep, goats, camels and antelopes.

What are the symptoms of Bacillus anthracis?

  • Fever and chills.
  • Swelling of neck or neck glands.
  • Sore throat.

Where is B. anthracis found?

B. anthracis is found in the soil, water, and vegetation and infects cows, sheep, and horses, which in turn infect humans after contact with contaminated materials. Fever and malaise usually appear progressively. Three forms of anthrax are found: cutaneous, intestinal, and pneumonic.

What is Ascolis test?

The Ascoli precipitin test is an old test, developed in 1911 to supply rapid retrospective evidence of anthrax infection in an animal product. It was designed to detect B. anthracis antigens in the tissues of animals and their byproducts.

What diseases are caused by Bacillus?

Although anthrax remains the best-known Bacillus disease, in recent years other Bacillus species have been increasingly implicated in a wide range of infections including abscesses, bacteremia/septicemia, wound and burn infections, ear infections, endocarditis, meningitis, ophthalmitis, osteomyelitis, peritonitis, and …

How does Bacillus anthracis affect the body?

People get infected with anthrax when spores get into the body. When anthrax spores get inside the body, they can be “activated.” When they become active, the bacteria can multiply, spread out in the body, produce toxins (poisons), and cause severe illness.

What antibiotic treats anthrax?

The standard treatment for anthrax is an antibiotic such as ciprofloxacin (Cipro), doxycycline (Vibramycin) or levofloxacin.

Can you survive anthrax?

Inhalation anthrax is considered to be the most deadly form of anthrax. Infection usually develops within a week after exposure, but it can take up to 2 months. Without treatment, only about 10 – 15% of patients with inhalation anthrax survive. However, with aggressive treatment, about 55% of patients survive.
