- How is UV radiation a good type of control mechanism against microbial growth? Explain what happens to the microbe and effects this control causes.how can ultraviolet be used to control microbial growth. which specific UV can be used to control microbe?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 options
- Why is it important for a microbiology laboratory technician to use aseptic technique?Why is it important to use sterile practices when working with microorganisms?There are various environmental factors that can influence microbial growth and reactions. These factors play a role which will determine if a microbe can function in a given environment. What are 2 environmental factors believed to be the most important out of the others ?
- What 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 handleWhich of the following statements regarding microbial control agents is FALSE? Question options: strongly acidic or alkaline disinfectants are typically more effective than neutral pH agents the presence of extracellular fats typically decreases the effectiveness of control agents a warmed disinfectant is typically more effective than the same disinfectant at room temperature substances secreted by members of biofilms increase protection against microbial control agents all of these statements are TRUE bacterial endospores are more resistant to antimicrobial treatment than vegetative bacterial cellswhy is it important that you disinfect your work area both before and after working with bacteria?
- Which of the following statements regarding microbial death is FALSE? Question options: cell walls are targeted by all microbial control agents all of these statements are TRUE many antimicrobial agents function through the disruption of protein structure under a given set of conditions, the fraction of a microbial population tht dies per minute is typically constant over time the effectiveness of an antibacterial agent is a function of its microbial death rate the rate at which microbes are killed is termed the microbial death ratethere 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?The clear zone around an antibiotic disk Multiple Choice is a plaque indicating the bacteria got killed is a zone of inhibition is a zone of inhibition indicating resistance of microbes is a zone of inhibition indicating susceptibility of microbes
