Capitolo 22, Problema 1
A fungus that can infect both healthy and immunocompromised patients is called
a(n) _______.
a. true pathogen
b. opportunistic pathogen
c. commensal organism
d. symbiotic organism
Guida verificata passo dopo passo1
Understand the definitions of the terms given in the options: a 'true pathogen' is an organism capable of causing disease in healthy individuals as well as those with weakened immune systems.
An 'opportunistic pathogen' typically causes disease only in immunocompromised or weakened hosts, not in healthy individuals.
A 'commensal organism' lives on or within a host without causing harm, often benefiting from the host without affecting it.
A 'symbiotic organism' refers to an organism involved in a close and often long-term interaction with another organism, which can be mutualistic, commensal, or parasitic.
Since the question asks for a fungus that can infect both healthy and immunocompromised patients, identify which term matches this capability based on the definitions.

Ecco i concetti essenziali che devi comprendere per rispondere correttamente alla domanda.
True Pathogen
A true pathogen is a microorganism capable of causing disease in healthy individuals with normal immune defenses. These pathogens have specific virulence factors that allow them to invade and damage host tissues regardless of the host's immune status.

Introduction to Pathogenic Toxins
Opportunistic Pathogen
An opportunistic pathogen causes disease primarily in immunocompromised or weakened hosts, taking advantage of reduced immune defenses. These organisms are usually harmless in healthy individuals but can cause infections when the immune system is impaired.

Commensal and Symbiotic Organisms
Commensal organisms live on or within a host without causing harm, often benefiting from the host environment. Symbiotic organisms engage in mutually beneficial relationships with the host. Neither typically causes disease under normal conditions.
