Question

question 46 (1 point) zoonosis refers to: a hospital - acquired infection a disease transmitted from animals to humans a fungal infection a viral disease question 47 (1 point) an opportunistic pathogen: is noninfectious causes disease in weakened hosts causes disease only in healthy hosts is always harmless

Explanation:

• Question 46: Zoonosis is defined as a disease that can be transmitted from animals to humans. For example, rabies (transmitted from infected animals like dogs to humans) is a well - known zoonotic disease. A hospital - acquired infection is called a nosocomial infection. A fungal infection is caused by fungi (e.g., athlete's foot), and a viral disease is caused by viruses (e.g., influenza), but these definitions do not match the concept of zoonosis.
• Question 47: An opportunistic pathogen is a microorganism that can cause disease when the host's immune system is weakened. For instance, Candida albicans (a fungus) can cause thrush in people with HIV/AIDS (a weakened immune state). Opportunistic pathogens are infectious (so “is noninfectious” is wrong), do not cause disease only in healthy hosts (as they rely on host weakness), and are not always harmless (they can cause disease in the right circumstances).

Answer:

• Question 46: B. A disease transmitted from animals to humans
• Question 47: B. Causes disease in weakened hosts
