Question
Chapter 9, Problem 11CT
Summary Introduction
To answer:
Whether Gram-positive bacteria or Gram-negative bacteria is more susceptible to antimicrobial drugs.
Introduction:
The antimicrobial drugs can be natural, synthetic, or semi-synthetic. These drugs act on the fungi, bacteria and viruses. These drugs are also used to control and eradicate the microbial growth. For example, some drugs are available in powder form that is applied on the

A common mechanism by which sensor cells in the host detect micro-organisms relies on the production of unique microbial components not found in the host. Propose a strategy by which a clever microbe could evade this type of response.
Define the terms antiseptic and disinfectant. using one named example of each describe their modes of action. Using named examples describe 3 modes of action of antibiotics. describe three ways in which bacteria may develop resistance to antibiotics.
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 ?

- Some antibiotics show no zone of inhibition against the microbe. How is this possible? Explain how the microbe is able to combat against the antibiotic with proper reasoning.arrow_forwardWhy might clinical medicine have an interest in understanding bacterial cell division at the molecular level? Explain why a hyperthermophile would probably not be a human pathogen. Describe four factors that may have an influence on the effectiveness of an antimicrobial treatment. Explain why 70% or 80% alcohol is more effective than 100% alcohol in controlling microorganisms.arrow_forwardThe statements are given below, which will best describe why antimicrobial drugs that affect cell wall synthesis tend to have selective toxicity when used by humans? Human cells only synthesize peptidoglycan as a food source Cell wall synthesis is a common metabolic process in humans and bacteria. Most bacteria only synthesize cell walls during their log phase of growth. Human cells do not have cell walls.arrow_forward
- Bacterial growth depends on many environmental factors, including the temperature of the environment. Since microbes can survive in a certain range of temperatures and will thrive at a temperature, understanding these variables allows for control of their growth. This understanding can be used, for example, to preserve certain foods or to treat infections. This lab simulation will use an instrument called a spectrophotometer. This instrument quantitatively measures the amount of light that is absorbed or transmitted by molecules in solution. Microbial populations grow at different rates based on temperature. One way to measure growth is by turbidity measurements. When bacteria multiply in a broth culture they turn the clear solution cloudy, or turbid. a) in your own words explain the proper steps to Inoculate 5°C sterile broth tube using aseptic techniquearrow_forwardList the four cellular agents of bacterium that most antimicrobial agents such as antibiotics target. Explain how each area is affected by the agent.arrow_forwardWhen 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.arrow_forward
- Citing the data from your results table tell which antibiotic is the most effective against this type of bacterium. Citing the data from the results table tell which antibiotic is the least effective against this type of bacterium. Explain how you determined the level of effectiveness. Describe what the Petri dish looked like. Hint(the most effective antibiotic has a larger clear area around the antibiotic disk. The least effective antibiotic has a smaller clear area around the antibiotic disk.arrow_forwardWhich of the following characterize biofilms that form within the body? (Check all that apply.) Group of answer choices Biofilms help microorganism adhere to human tissue. Biofilms are formed only by Gram-positive bacteria. Biofilms protect microbes from the body’s defenses. Biofilms protect microorganisms from antibiotics. Biofilms are usually made up of only one species of bacteria.arrow_forwardNote that it is not appropriate to self-diagnose outside of a medical context and this is a completely hypothetical scenario. Imagine you have a rash on your foot. You're concerned that it's an infection and inoculate a sample onto an agar plate. You wonder, How can I figure out whether the pathogen is a bacterium vs a eukaryote? You decide to use lab supplies to get a basic understanding of the pathogen. Be specific about what tests you use and what you expect the results to be. Limit yourself to experiments we could do in our lab. What is one experiment you could do, involving culturing the organism?arrow_forward

Do these microbes typically cause disease in humans? Consider the environment in your body and the environment in which the microbes are growing.arrow_forwardDiseases that involve biofilm-producing bacteria are of serious concern. They are not as easily treated compared with those involving free-floating (or planktonic) bacteria. Explain three reasons why biofilm formers are more pathogenic. Brian goes to the hospital after not feeling well for a week. He has a fever of 38 °C (100.4 °F) and complains of nausea and a constant migraine. Distinguish between the signs and symptoms of disease in Brian’s case.arrow_forward
