Summary Introduction

Introduction:

Symbiosis is a process that provides a close relationship between two species where both the species share common habitat. Members that take part in symbiotic relationships are called “symbionts”.

Answer to Problem 1MC

Correct answer:

Mutualism is a type of symbiosis in which both members benefit from their interaction. Therefore, option (a) is correct.

Option (a) is given as “mutualism”.

Explanation of Solution

Justify reasons for the correct statement:

The symbiotic relationship that benefits both the members is termed as mutualism. Mutualism improves the fitness of both members. For example: Bacteria that live in the colon of human receives a moist, warm and nutrient-rich environment in which it can proliferate and human absorb vitamin precursors along with other nutrients from bacteria.

Hence, option (a) is correct.

Justify reasons for the incorrect statements:

Option (b) is given as “parasitism”.

In this relationship, one member or species get resources at the cost of a living host. Hence, it is a wrong answer.

Option (c) is given “commensalism”.

In this relationship, one member is benefitted while other remains unaffected significantly. Hence, it is a wrong answer.

Option (d) is given as “pathogenesis”.

Pathogenesis is an event in which an infection occurs in the host’s body. Hence, it is a wrong answer.

Hence, options (b), (c) and (d) are incorrect.Microbiology with Diseases by Taxonomy (5th Edition), Chapter 14, Problem 1MC

Conclusion

In mutualism, both the species are benefitted with the presence of one another.

We will be starting a group project next week where you and your group will research and ultimately present on a current research article related to the biology of a pathogen that infects humans. The article could be about the pathogen itself, the disease process related to the pathogen, the immune response to the pathogen, vaccines or treatments that affect the pathogen, or other biology-related study about the pathogen. I recommend that you choose a pathogen that is currently interesting to researchers, so that you will be able to find plenty of articles about it. Avoid choosing a historical disease that no longer circulates. List 3 possible pathogens or diseases that you might want to do for your group project.
