Textbook Question
Chapter 9, Problem 11CT
Would you expect Gram-negative bacteria or Gram-positive bacteria to be more susceptible to antimicrobial chemicals that act against cell walls? Explain your answer, which you should base solely on the nature of the cells’ walls (see Figure 3.15).

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.
Choose the false statement below.
O Effective antimicrobials may not be used commercially because of their mode of delivery or the
time it takes them to leave the body.
O Decontamination of an object is not necessary if disinfection is done properly.
O In general, acid fast bacteria are less sensitive to antimicrobials than are Gram-negative bacteria
or fungi.
Question 8
Choose the false statement below:
O Using three different classes of antimicrobials in combination greatly decreases the chance of
developing resistance because the drug resistance strategy for one is the same for others.
O Drug resistance to antimicrobials has proven to be extensive against chemotherapeutics as well
as other chemical antimicrobials.
O Collateral damage is a term that refers to the killing of normal body flora as well as pathogenic
bacteria when taking antimicrobials or antibiotics.
Why 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.

- 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_forwardThe type of antimicrobial drug that would be most likely to have toxic effects in humans based on the premise of selective toxicity when treating microbial infection would be a drug that O 1) inhibits the synthesis of the cell wall O 2) inhibits metabolic pathways O 3) disrupts the cytoplasmic membrane 4) inhibits protein synthesis 5) All of the above have equal potential to be toxicarrow_forwardList all the antibiotics in the above table that work through destroying the bacterial cell wall.

- 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.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.
