- a. true pathogen
- b. opportunistic pathogen
- c. commensal organism
- d. symbiotic organism
Introduction:
Fungi are defined as eukaryotic and multicellular organisms that depend on other organisms for food. They are different from plants and animals. They reproduce by both asexual and sexual means.
Answer to Problem 1MC
Correct answer:
True pathogens are the type of fungus that can infect both healthy individual and immunocompromised patients. Therefore, option (a) is correct.
Option (a) is given as “true pathogens”.
Explanation of Solution
Justify reason for the correct statement:
True pathogens are those fungi that have an ability to cause infection in both healthy individual with strong immune system and immunocompromised patients with weak immune system. For example: Histoplasma capsulatum, Coccidioides immitis, and Blastomyces dermatitidis.
Hence, option (a) is correct.
Justify reasons for the incorrect statements:
Option (b) is given as “opportunistic pathogen”.
Opportunistic fungi are those fungi that only infect individuals having weak immune system. Hence, it is a wrong answer.
Option (c) is given as “commensal organisms”.
Commensalism is a type of relationship in which one organism gets benefited and the other is neither harmed not benefited. Hence, it is a wrong answer.
Option (d) is given as “symbiotic organisms”.
It is a type of relationship in which both organisms are benefitted from each other. Hence, it is a wrong answer.
Hence, options (b), (c), and (d) are incorrect.
True pathogens are the fungi that cause infection to both healthy individual and immunocompromised patients.
