- 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 ?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 optionsWhy is it important to use sterile practices when working with microorganisms?
- When heat treatment is used as to control microbial growth, what is the immediate impact of this increased temperature? The microbe's DNA is digested and the microbe can no longer reproduce. The microbe is unable to attach to host cells. The microbe is unable to synthesize and secrete toxins. The microbe's food is destroyed and the microbe is without a food source. The microbe's proteins are denatured and the membranes are disrupted.there 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?Identify two factors( in detail)that make biofilms more tolerant to antimicrobials including their mode of action.
- Which of the following types of antimicrobial drugs make microbes more susceptible to osmotic pressure? 1) drugs that inhibit nucleic acid synthesis O 2) drugs that inhibit metabolic pathways 3) drugs that inhibit cell wall synthesis 4) drugs that block a pathogen's recognition of its host 5) drugs that inhibit protein synthesisAfter streaking microbial culture on agar plates and observing colonial growth, TMTC usually happens. What are the causes of TMTC plates (plates with more than 300 colonies that cannot be counted)? What are the ways to prevent this from happening?Why is there a need for an incubator in the lab? How about incubating cultures at room temperature? How can this affect microbes?
