Which agent can be used to kill bacterial endospores?

Glutaraldehyde 2% This disinfectant does not necessarily kill all bacterial endospores, but it is approved by the U.S. Food and Drug Administration (FDA) as effective against all vegetative bacteria, mycobacteria, fungi, and viruses. Instruments must remain submerged for at least 20 minutes in this solution.

How can endospores be killed?

While resistant to extreme heat and radiation, endospores can be destroyed by burning or by autoclaving. Endospores are able to survive boiling at 100°C for hours, although the longer the number of hours the fewer that will survive.

Which of the following does not kill spores?

Answer and Explanation: The correct answer is B. Pasteurization.

Which of the following are typically irradiated in order to kill microbes?

What kills bacterial spore?

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 machine called an autoclave.

Which of the following processes removes or destroys endospores?

Sterilization: Killing or removing all forms of microbial life (including endospores) in a material or an object. Heating is the most commonly used method of sterilization.

How do you kill bacterial endospores?

As a general rule, only a few disinfectants are strong enough to kill bacterial endospores within a short period of time. Usually they are strong oxidants like 1:10 diluted bleach. Among antimicrobial devices, strong ultraviolet light-based systems are the best bet for endospore killing.

Which of the following is most effective against resistant endospores?

Alcohols are widely used as antiseptics and disinfectants because they are effective against endospores as well as vegetative cells.

Which of the following methods is possible to kill bacteria?

Autoclaving is the most reliable method of sterilization or killing bacteria and other microorganisms. It is used for all materials that contain water, and are permeable or wettable and not liable to be damaged by the process.

Which of the following would be an effective process to eliminate resistant endospores?

Given proper time, temperature, and pressure, endospores can be killed by the autoclave.
