- For sterilization to occur correctly it must include; heat and pressure: true Falsethere are different methods to be used in order to control opportunistic infection and that includes cleaning, sanitizing, disinfecting, sterilizing... And that depends how they can be applied according to the area and level the health care worker or scientist is and the environment. Do you know how these methods of microbial growth are applied and where?As the temperature of pasteurization increases, the time of treatment decreases. As the temperature of pasteurization increases, the time of treatment decreases. True False
- There is definitely survival of some microorganisms even after alcohol treatment. Without staining or microscopic scrutiny, predict what types of microbes are growing on the medium where you made the right thumb impression after treatment.In the laboratory, autoclaving is required to prepare media for the growth of microorganism. What type of method of control does this involve? Dry Heat Moist Heat Chemical Radiation All of the optionsWhat is the purpose of fixing a smear? Mark all that apply: 1. To attach the bacteria to the slide 2. To cause the cells to shrink and become distorted 3. To kill the bacteria so they aren't harmed by the staining method 4. To break down the cell wall in order to make the cells accept stain 5. To kill the bacteria to make the slide safer to handle
- Which of the following are true regarding UV disinfection? Mark all that apply. Water must be clear, so light can kill pathogens It is the cheapest method of disinfection The water has to flow at a specific speed past the UV light Only about 85% of pathogens are killed by UV It is very rarely used in water disinfection due to high costsDo you think UVC disinfection of N95 face masks is effective? Give two important considerations for UVC disinfection of N95 face masks to be effective?According to CNN, the FDA has a warning list, with over 100 different types of hand sanitizers to avoid. Please mention a few of them and explain why should we avoid them. Also, please provide images if possible. Thank you
- In some hospitals, short wavelength irradiation of patients room is a way to kill pathogens and endospores contaminating surfaces. True or false?Use of chemical agents to destroy microbes on skin or tissues Reinoval of microbes from surfaces by scrubbing Removal or destruction of all microbes Use of chemical agents to destroy microbes on surfaces used by the public Use of physical/chemical agents to destroy microbes on non-living objects Free of contamination by pathogens Antisepsis (antiseptic) Aseptic Degerming Sanitization Sterilization DisinfectionThere are so many microbes in a single mL of culture, it is very difficult to perform one dilution to produce countable cells. Microbiologists need to perform a dilution series, where multiple dilutions are performed in sequence to arrive at the correct dilution. Dilutions are cumulative. Multiple the series of dilutions together to find the final dilution value. If 3 serial dilutions are performed, each with a value of 0.01, what is the cumulative dilution? Express your answer as an exponent, e.g. 0.1 would be 1e-1 and 0.01 would be 1e-2
