When production of a drug all work area surfaces must be disinfected?
During production of a drug, all work area surfaces must be disinfected using sterilized disinfectants. Which of the following statements about disinfectants are true? Select all that apply.
Which is the most commonly used application of moist heat for sterilization?
Autoclaving is the most commonly used application of moist heat for sterilization. Which of the following statements about autoclaving is true? Choose the statement about autoclaving that is true.
What are the microbial targets of disinfecting chemicals?
List the microbial targets of disinfecting chemicals and provide one example of a chemical agent that affects that structure. Four main categories of cellular targets for chemical agents. - Cell wall. - Cell membrane. - Cellular synthesis processes (DNA, RNA).
When does most of the cell death occur during antimicrobial treatment?
Most of the cell death occurs early in the treatment. The following microbial death curves were collected from a variety of antimicrobial treatments used on different E. coli samples. Arrange the graphs below in order of the effectiveness of these treatments.
How do disinfectants work?
Disinfection can occur by physical or chemical means. Disinfectants are used to inhibit or destroy pathogens. Assume that you have an antimicrobial agent specific for each of the targets listed below. Indicate which type of microbe would be most susceptible to the agent by placing it in the appropriate bin.
Does heat sterilize food?
The higher temperatures kill most contaminating microbes and endospores and therefore effectively sterilize the food. Use of moist heat can control microbial growth in many circumstances, but heat-sensitive items and those susceptible to moisture cannot be sterilized in this manner.
What is chlorine used for?
Chlorine has traditionally been used to disinfect water, preventing the spread of waterborne illnesses. However, chlorine (and other disinfectants) can react with naturally occurring water chemicals, forming ______, which can have long-term health risks.
Which government agency regulates germicidal chemicals?
T/F: The government agencies that regulate germicidal chemicals are the Food and Drug Administration (FDA) and the Environmental Protection Agency (EPA). true. Silver sulfadiazine, a combination of silver and a sulfa drug, is used to. prevent infection of second- and third-degree burns.
How does thymine work?
Works by producing thymine dimers in DNA strands. Most effective at close range and with long duration of exposure. -High energy radiation that directly destroys DNA and damages cytoplasmic membranes. It can also cause indirect damage by producing reactive oxygen species (ROS).
Does boiling water kill microbes?
It can also cause indirect damage by producing reactive oxygen species (ROS). -Doesn't affect microorganisms directly, but can generate heat in fluids which can indirectly kill microbes. Boiling is not reliable for sterilization because. heat-resistant endospores are unaffected.
