Quizplus · Accepted Answer

Dysbiosis refers to an imbalance in the microbiome that can occur due to various factors, including taking antimicrobial medications, and can lead to negative interactions between hosts and their microbial communities.

Answer: B
 Parasitism is a type of symbiotic relationship between two organisms in which one partner (the parasite) benefits and the other is harmed (the host). This is not specific to interactions between hosts and microbes, but can include various types of organisms.

The other answer choices are incorrect:
A) Immunocompetent refers to having a fully functional immune system, rather than a weakened one.
D) Secondary infection refers to an infection that occurs after a primary infection has already occurred, rather than a specific interaction between hosts and microbes.
E) Fc receptors are molecules on immune cells that bind to the Fc region of antibodies, allowing for various immune functions. While this is related to host-microbe interactions, it is a specific component of the immune response rather than an overarching concept.
