Chapter 3, Problem 4TMW
Summary Introduction
To determine:
The reason that microbe illustrated in Figure 3.2 more likely a Gram-positive bacterium than a Gram-negative one.
Introduction:
The bacterial cells are protected by a cell wall, composed of peptidoglycan. It is a unique molecule made up of polysaccharides that are linked by amino acids. Based on the structure of the cell wall there are two types of the bacteria: Gram-positive bacteria and Gram-negative bacteria.

When do we make the determination that a bacterium is Gram positive?
A) Safranin washes the crystal violet die out of the cell wall.
B) Crystal violet die is not able to absorb into the cell wall.
C) Alcohol does not wash the crystal violet die out of the cell wall.
D) Crystal violet turns the bacterium a yellow color.
It is 0.4 um in length, but that is all you know. What could you do to determine if this microbe was a bacteria or an archaea?
How does the growth rate of a specific bacterium impact how easy or difficult it is to treat clinically?

- Diseases 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_forward1) Listen In the lab you are testing a bacterium's oxygen requirement for growth. You grow your bacterium in a test tube, without shaking at the appropriate temperature. The next day you find that your bacterial culture is growing only at the top surface (ie at the top of the tube closest to the cap) and not dispersed throughout the test tube. What term would be used to describe the oxygen requirement of this bacterium? O A) Obligate aerobe. O B) Microaerophile. O C) Anaerobe. D) Obligate anaerobe. E) Facultative anaerobe.arrow_forwardWhat is a micrometer (μm )? Is it really possible to see microbes with this dimension using Leeuwenhoek’s “primitive” microscopes?arrow_forward
