Which of the following diseases are caused by Endospore forming bacteria?
Infectious diseases such as anthrax, tetanus, gas gangrene, botulism, and pseudomembranous colitis are transmitted to humans by endospores.
Which disease is an example of one caused by a spore?
Anthrax is a rare but serious illness caused by a spore-forming bacterium, Bacillus anthracis. Anthrax mainly affects livestock and wild game. Humans can become infected through direct or indirect contact with sick animals.
What makes endospores resistant to external forces?
In endospore formation, the bacterium divides within its cell wall. Endospores can survive without nutrients. They are resistant to ultraviolet radiation, desiccation, high temperature, extreme freezing and chemical disinfectants.
What is Endospore formation?
An endospore is a dormant, tough, and non-reproductive structure produced by certain bacteria from the Firmicute phylum. Endospore formation is usually triggered by lack of nutrients, and usually occurs in Gram-positive bacteria. In endospore formation, the bacterium divides within its cell wall.
What is the advantage of forming endospores?
Endospores can survive without nutrients. They are resistant to ultraviolet radiation, desiccation, high temperature, extreme freezing and chemical disinfectants. While resistant to extreme heat and radiation, endospores can be destroyed by burning or by autoclaving.
Are endospores good or bad?
Bacteria propagate when times are good. When times are bad, certain bacteria have the capability to shrink down and encrust critical cellular elements in a tough casing. This is called an endospore. The endospores are a purified Clostridum difficile spore suspension.
Which bacteria are spore forming?
Spore-forming bacteria include Bacillus (aerobic) and Clostridium (anaerobic) species. The spores of these species are dormant bodies that carry all the genetic material as is found in the vegetative form, but do not have an active metabolism.
Can viruses form spores?
Organisms known for producing Spores include bacteria, fungi, protists and some plants. The Spores often bear gametes and other structures that, in favorable conditions, develop into new individuals. So, to answer your question: No, Viruses do not produce spores.
How do you kill spores?
Chemical disinfectants can kill bacteria, but they do not destroy their spores. A process called sterilization destroys spores and bacteria. It is done at high temperature and under high pressure. In health care settings, sterilization of instruments is usually done using a device called an autoclave.
