Practical Medical Microbiology Lab Sterilization and Disinfection Quiz

The process of killing all microorganisms, including bacterial spores, using methods like heat, radiation, or chemicals.

The process of reducing the number of pathogenic microorganisms to a safe level, often using chemical disinfectants.

The absence of significant contamination by microorganisms, often achieved through techniques like sterile equipment and practices.

Agents that kill bacteria, including their resistant endospores, effectively eliminating bacterial populations.

Agents that inhibit the growth of bacteria, preventing them from multiplying but not necessarily killing them.

The presence of bacteria in the blood or other tissues, often leading to systemic infection and complications.

The process of reducing the number of microorganisms in a public setting to a safe level, often using chemicals or cleaning methods.

Agents applied topically to living surfaces to prevent infection by inhibiting the growth of microorganisms.

The natural process of sterilization by the ultraviolet rays of sunlight, effectively killing microorganisms.

A method of sterilization that focuses on removing microorganisms from heat-sensitive solutions using filters with pore sizes small enough to trap microbes.

A type of radiation, like X-rays or gamma rays, that carries enough energy to damage DNA and kill microorganisms.

A dry heat method of sterilization that involves heating an instrument in a Bunsen flame until it glows red hot, killing all microorganisms.

A method of pasteurization used in the food and dairy industry that involves heating the product at 63°C for a specific duration to kill harmful microorganisms.

A method of sterilization using moist heat, typically involving heating glassware at 180°C for 30 minutes to ensure complete sterilization.

The main mechanism by which moist heat sterilizes microorganisms, by breaking down the proteins essential for microbial survival and function.

The process of removing microorganisms from air using specialized filters known as HEPA filters, which capture particles with remarkable efficiency.

The most commonly used and highly effective method for treating infectious waste in hospitals. It involves burning the waste at high temperatures, completely eliminating all microorganisms and making it safe.
