We are a product of our genes, so they say; however, we are also populated by microbes. Some we cannot do without, but others wait around until our defenses are down and then they strike. During your examination of the topics in this chapter, consider the following:
Which characteristics of bacterial cells allow them to cause disease in humans?

To determine: The characteristics of bacteria cells that allow them to cause disease in humans.
Introduction: Prokaryotes are the oldest form of life on Earth that belongs to the domain Archaea and bacteria. They are single-celled microscopic organisms and they do not possess true nucleus or membrane-bounded organelles. The prokaryotes are found to be both beneficial as well as harmful to humans.
Explanation of Solution
The bacterial cells possess certain characteristics that make them cause infections or diseases in humans. The virulence factors are the characteristics of the bacteria that enhance its ability to cause disease. The cell structure of the bacteria acts as the virulence factors that include: LPS (lipopolysaccharide), S-layer, mycolic acid, fimbria, capsule, pili, and endospores.

- We are a product of our genes, so they say; however, we are also populated by microbes. Some we cannot do without, but others wait around until our defenses are down and then they strike. During your examination of the topics in this chapter, consider the following: What types of relationships do we have with the microbial world?arrow_forwardJust as with most living beings, bacteria require the proper conditions to grow and reproduce. Rarely are bacterial cells found alone; so, you could say they are social beings. During your examination of the topics in this chapter, consider the following: Do different bacteria prefer different temperatures?arrow_forwardIn a 400-600 word answer, properly cited with an APA-formatted reference list and in-text citations, please answer the following questions. In addition to the researched facts you present as your answer, you may provide opinions and real-world experiences where appropriate. Although much of this course is focused on microorganisms that are considered pathogens and have the potential to cause disease in humans, there are numerous microbes that are on our side or at least list side-by-side with us without causing trouble. There are many bacteria and fungi on or in our bodies that are beneficial or are necessary for good health. Summarize the benefit (or need) for “good” microorganisms in and on the body. Choose a part of the body that is normally colonized by “good” microorganisms (e.g.- skin, intestines, vagina, other). List examples of normal microbes and their relationship with the human body. What factors or specific pathogens could threaten this microbial population and how can a…arrow_forward
