Only one endospore is formed per cell. The spores are resistant to heat, cold, radiation, desiccation (drying out) and disinfectants.
Anthrax has infected humans throughout recorded history. The fifth and sixth plagues of Egypt described in Exodus are believed to have been anthrax.
The disease was featured in the writings of Virgil in 25 BC and was familiar in medieval times as the Black Bane. It was from studies on anthrax that Koch established his famous postulates in 1876, and vaccines against anthrax, the best known being that of Pasteur (1881), were among the first bacterial vaccines developed.

Does not describe spores produced by bacillus anthracis causative agent of anthrax?
Sensitive to UV light
What is clostridium anthracis?
Clostridium anthracis is a bacterium that causes anthrax, a serious infectious disease primarily affecting livestock and occasionally humans. It can form spores that can survive in the environment for long periods of time, leading to the potential for outbreaks in animal populations or human exposure through contact with contaminated animal products. Anthrax can be treated with antibiotics if promptly diagnosed.
Is bacillus anthracis a good or bad bacteria and why?
Bacillus anthracis causes the disease anthrax. Anthrax is a life-threatening infectious disease that normally affects animals (such as goats, cattle, sheep, and horses). Anthrax can be transmitted to humans by contact with infected animals or their products. Anthrax does not spread from person to person. In the soil, where they live, anthrax organisms exist in a dormant form called spores. These spores are difficult to destroy. The spores have been known to survive for as long as 48 years. Ingestion of anthrax can cause serious, sometimes fatal disease.The most deadly form is inhalation anthrax. If the spores of anthrax are inhaled, they spread, and produce toxins that often cause death.The greatest threat of anthrax today is through a bio-terrorist attack which would be delivered as an aerosol.It is considered "bad".
What disease does Bacillus anthracis cause?
Bacillus anthracis is a gram positive, aerobic, endosporic bacteria. Human infection is usually through the cut or abrasion of the skin, resulting in cutaneous anthrax; however, inhaling spores may result in pulmonary anthrax, also known as woolsorter's disease. If spores reach the gastrointestinal tract, gastrointestinal antrax may result The principle virulence factor of B. anthracis are encoded on two plasmids- one involved in the synthesis of polyglutamyl capsule that inhibit phagocytosis and the other bearing the genes for the synthesis of its exotoxins.
Why should you use an old culture for the endospore stain?
Spores are typically formed when an organism is enduring stressful conditions. If you wait until the culture is old then it is likely that some of the organisms will be experiencing stressful conditions such as lack of nutrients. It helps if you remember why the organism forms spores at all! The organism is protecting itself against harsh conditions, the spore will not germinate until conditions favour growth.
Does not describe spores produced by bacillus anthracis causative agent of anthrax?
Sensitive to UV light
What is Sorters disease?
A pulmonary form of anthrax that results from the inhalation of spores of the bacterium Bacillus Anthracis in the wool of contaminated sheep. The bacterium that causes this is Bacillus Anthracis
Whiat describes spores produced by Bacillus anthracis causative agent of anthrax?
The spores produced by Bacillus anthracis, the causative agent of anthrax, are highly resistant and can survive in harsh environmental conditions for long periods. They are usually oval-shaped, have a tough outer layer, and are capable of forming protective structures called endospores. These spores are the infectious form of the bacteria and are responsible for the spread of anthrax.
Spores produced by bacillus anthracis?
The anthrax bacterium can form spores. these can be blown through the air and inhaled or gotten into cuts. You can also get it from animals dead from it and it can go though the skin forming an ugly sore.
What is the chemical formula of anthrax?
Anthrax is really a bunch of spores of a microbe called bacillus anthracis. These spores are very resistent to drying out and harsh environmental conditions, making them survive for long times. Once these spores settle and grow into the bacterium, this bacterium releases an anthrax toxin that can cause life threatening pneumonia if the bacterium/spores were inhaled and settled in your lung.
Can spores produced by bacillus anthrax remain viable in soil for years?
Thousands of years.
What is clostridium anthracis?
Clostridium anthracis is a bacterium that causes anthrax, a serious infectious disease primarily affecting livestock and occasionally humans. It can form spores that can survive in the environment for long periods of time, leading to the potential for outbreaks in animal populations or human exposure through contact with contaminated animal products. Anthrax can be treated with antibiotics if promptly diagnosed.
What statement describe spores produced by bacillus anthraciscaustive agent of anthrax?
Since there is not any information provided about the statements the answers will not be known. It is important to include the statements to know which does not describe the spores.
What are the genera of bacteria which forms spores?
bacillus and clostridium

Which two foods may contain the spore of bacillus cereus?
Rice and wheat. Bacillus cereus spores are found in cereal grains.
Why is it hard to kill bacillus with a disenfectant?
Bacillus sp form spores which protect them from toxins & high temperature levels. It will take more than a disinfectant to kill a Bacillus species.
