Diseases Caused By Endospore Forming Bacteria?

What are the Endospore forming bacteria?

In endospore formation, the bacterium divides within its cell wall, and one side then engulfs the other. Examples of bacterial species that can form endospores include Bacillus cereus, Bacillus anthracis, Bacillus thuringiensis, Clostridium botulinum, and Clostridium tetani.

Why are endospores dangerous to humans?

Endospores are highly dangerous bio-terrorist weapons. This is because they are smaller than the vegetative state. A bacterium, in itself, is already smaller than a eukaryotic cell. Therefore, considering the small size of endospore, a small volume of it can already contain a large quantity of it.

What conditions favor spore production in Endospore forming bacteria?

Examples of bacteria that can form endospores include Bacillus and Clostridium. Endospores can survive without nutrients. They are resistant to ultraviolet radiation, desiccation, high temperature, extreme freezing and chemical disinfectants.

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.

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.

Can Antibiotics kill endospores?

Prolonged exposure to ionising radiation, such as x-rays and gamma rays, will also kill most endospores. Bacterial endospores are resistant to antibiotics, most disinfectants, and physical agents such as radiation, boiling, and drying.

Do endospores cause disease?

Endospores are quite resistant to high temperatures (including boiling), most disinfectants, low energy radiation, and drying. Infectious diseases such as anthrax, tetanus, gas gangrene, botulism, and pseudomembranous colitis are transmitted to humans by endospores.

Can boiling water destroy endospores?

Boiling is one of the oldest methods of moist-heat control of microbes, and it is typically quite effective at killing vegetative cells and some viruses. However, boiling is less effective at killing endospores; some endospores are able to survive up to 20 hours of boiling.

What kinds of conditions can endospores survive?

Endospores can survive without nutrients. They are resistant to ultraviolet radiation, desiccation, high temperature, extreme freezing and chemical disinfectants. They are commonly found in soil and water, where they may survive for long periods of time. Bacteria produce a single endospore internally.

Why are spores so difficult to destroy?

Other organisms form spores, but the bacterial spore is generally more heat resistant and difficult to denature. The greater heat resistance is hidden in the very structure of an endospore. Note that the bacterium is in the center of the endospore. The endospore makes it difficult to kill bacteria.

How many endospores can a bacteria produce?

Unlike fungal spores, where one fungus can make many spores, bacterial endospores are a “one cell makes one endospore” affair. Endospores exhibit no signs of life, however when the environment returns to a favorable state for bacterial growth the bacterial endospore will germinate and return to a normal state.

What can kill bacterial 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.

Does bleach kill spores?

Bleach and vinegar can both kill mold, but vinegar is much more effective for removing mold from porous materials. This is because bleach only kills mold spores on the surface of affected materials.

What kills spores in food?

Most microbial cells will die at a temperature of 100 ºC. However, some bacterial spores will survive this and need temperatures around 130ºC to kill them. This should kill all the microbes and their spores. Some foods (like milks, soups and sauces) are heated to around 132ºC for a short time.
