Figure 22.8 Compared to free-floating bacteria, bacteria in biofilms often show increased resistance to antibiotics and detergents. Why do you think this might be the case?
Which of the following is not true about biofilms a) are caused by many Gram positive and Gram negative bacteria as well as algae and fungi b) are highly contagious c) are hard to treat due to impermeability to drugs
Which of the following is true of microbial biofilms? A. Biofilms are restricted to freshwater environments. B. Biofilms typically are small because resources such as nutrients and oxygen are unable to circulate through them. C. Cells within the biofilm are encased within a layer of polysaccharide. D. Biofilms almost always consist of only a single bacterial species
Which 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.
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.
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 technique

Bacteria have three major methods of resisting antibiotics. They may lack (or modify) the feature that the antibiotic targets, so that the drug has little or no effect. The may have an enzyme that helps them break down and inactivate the antibiotic. They may have efflux pumps that remove the drug from the cell. Which method of resistance are Gram-negatives particularly famous for? Group of answer choices target modification enzymatic breakdown horizontal transfer efflux pumps
