|---|---|
| Which common hospital pathogen is able to grow abundantly in soap dishes? | Escherichia coli |
| All of the following are correct about the autoclave except | it is important not to overload the chamber. |
Which of the following is officially accepted as a sterile and high level disinfectant?
Which of the following is officially accepted as a sterilant and high-level disinfectant? vegetative bacteria and fungi.
Are most microbial contaminants of food killed at freezing temperatures?
Most microbial contaminants of food are killed at freezing temperatures. Filtration is an effective method to remove microbes from air and liquids. Chlorine compounds remain stable and effective in the presence of excess organic matter.
Which of these metals have antimicrobial properties associated with them?
titanium, cobalt, nickel, copper, zinc, zirconium, molybdenum, tin, and lead have been tested for their antibacterial properties against two bacterial strains, Gram-positive Staphylococcus aureus and Gram-negative Escherichia coli.
Is a treatment that uses 134 C for 1 to 2 seconds and can be used as a method for sterilizing milk?
In ultra-high-temperature (UHT) pasteurization, milk is pasteurized at 135 °C (275 °F) for 1–2 seconds, which provides the same level of safety, but along with the packaging, extends shelf life to three months under refrigeration.
What is the minimum sterilizing conditions in a steam autoclave?
The minimum sterilizing conditions in a steam autoclave are: 121° C at 15 psi for 15 minutes. The shortest time required to kill all the microbes in a sample at a specified temperature is called the: thermal death time (TDT).
What is the fastest method of sterilization?
Filtration is the quickest way to sterilize solutions without heating. This method involves filtering with a pore size that is too small for microbes to pass through. Generally filters with a pore diameter of 0.2 um are used for the removal of bacteria.
What is the most commonly used hospital disinfectant?
Hypochlorites are the most commonly used chlorine disinfectants. Sodium Hypochlorite is commercially available as household bleach. This EPA-registered chemical is stable and fast acting. While generally considered safe, bleach can cause skin and eye irritation.
What is the lowest temperature required to kill all microbes in a sample in 10 minutes?
thermal death time is the shortest amount of time required to kill an organism at a 100 degrees C, whereas thermal death temperature is the lowest temperature required to kill an organism in 10 minutes.
What are the minimum sterilizing conditions in a steam autoclave?
How do phenols kill bacteria?
A type of antimicrobial agent used as a disinfectant, called a phenol, uses a similar process to kill off bacteria on inanimate objects through the inactivation of their enzyme systems. Well, our phenols cause the cells whose enzymes they pop off to crash, burn and die as well.
What metal is naturally antibacterial?
Copper and its alloys (brasses, bronzes, cupronickel, copper-nickel-zinc, and others) are natural antimicrobial materials. Ancient civilizations exploited the antimicrobial properties of copper long before the concept of microbes became understood in the nineteenth century.
